  • The Science Behind Climate Change – What You Need to Know.

    The Science Behind Climate Change – What You Need to Know.

    Changes in Earth’s climate are consistent with an increase in heat-trapping greenhouse gases due to human activities, including burning fossil fuels (coal, oil and natural gas) and land-use changes. This warming phenomenon has its source in human activities like burning fossil fuels (coal, oil and natural gas).

    Increased concentrations of these gases are also contributing to more complex climate processes that accelerate, including Arctic sea ice reduction and energy transfer from ocean to atmosphere.

    Climate change is happening.

    Scientists agree on one point: climate change is real and human activity is the cause. Earth has experienced climate changes throughout history, but nothing compares with the rapid global temperature rise we’ve witnessed since mid-20th century. Human activities largely contribute to this rate of warming as fossil fuel use creates heat-trapping greenhouse gasses which trap heat inside our atmosphere and lead to warming trends like this one.

    As these gases absorb and trap solar heat, they warm the planet while altering natural systems – this phenomenon is known as the greenhouse effect and it’s the main driver behind climate change. Interacting gases further amplify initial warming processes and lead to further changes; for instance, carbon dioxide and other greenhouse gases found in air can deplete stratospheric ozone levels which in turn leads to further warming effects.

    Recent studies show that human activities, primarily the burning of fossil fuels, are driving global warming. Human actions increase heat-trapping greenhouse gases in the atmosphere, especially CO2. Scientists can measure old carbon in modern atmosphere and compare it with past levels – this evidence confirms that current CO2 levels exceed those before the Industrial Revolution.

    Global temperatures are increasing at an alarming rate and they’re impacting everyone, everywhere. Altering weather patterns put our lives in jeopardy – from devastating floods and prolonged drought to sea level rise and sea level remapping – even leading to food shortages, loss of biodiversity, more frequent extreme weather events that damage infrastructure and harm communities.

    Weather fluctuations will continue naturally, yet scientific evidence overwhelmingly points to climate change as being real and having serious repercussions now. Without swift action to reduce our emissions of heat-trapping greenhouse gases, risks will only worsen further – often leaving the poorest countries and people of color to bear its brunt.

    It’s caused by humans.

    Human activities have been the primary contributor to climate change over the last century, particularly the combustion of fossil fuels like oil, gas and coal that produce carbon dioxide (CO2). CO2 traps heat in the atmosphere and warms our planet; other human influences include deforestation, changes to land cover and water use.

    These changes alter our planet’s energy balance, affecting global temperatures and weather patterns as well as biodiversity, food safety and availability, water scarcity, poverty, conflict and migration. Climate change affects everyone.

    Climate can be affected by both natural forces like volcanic eruptions and human activities like deforestation; however, human activities have the greatest effect. A major contributor is carbon dioxide (a “heat trapping gas”) from human activity – whether through burning fossil fuels such as coal, oil or natural gas or deforestation, agriculture or land-use changes as well as deforestation, agriculture or any other means.

    Arrhenius first proposed in 1859 that rising atmospheric CO2 levels may contribute to global warming; however, his work failed to gain widespread support at that time as geologic evidence showed ice ages occurring over thousands of years and laboratory experiments suggested changes in CO2 levels had little bearing on heat absorption.

    Carbon isotope measurements provide scientists with compelling evidence of our role in driving recent increases in carbon dioxide. Scientists can use carbon isotope measurements to distinguish between “older” carbon molecules produced through burning fossil fuels and natural living system production; and “newer” lighter carbon atoms produced through living systems – with the older carbon having its own distinctive isotopic fingerprint making its identification straightforward.

    Scientific studies are increasingly exploring the impact of human-driven climate change on various aspects of life. Researchers have demonstrated how higher CO2 levels make extreme events–like the 2003 European heatwave that killed tens of thousands–more likely. Climate change also made record temperatures during Hurricane Harvey three times more likely.

    It’s dangerous.

    Scientists, researchers, and affected individuals worldwide report changes that go beyond normal temperature fluctuations on land and in the oceans, rainfall patterns, and many other systems on our planet. These anomalous changes are evidence of global warming caused by human activities like burning fossil fuels and deforestation that increase heat-trapping gases in our atmosphere.

    Carbon dioxide (CO2) and other air pollutants accumulate for decades to centuries in our atmosphere, blocking out part of Earth’s heat radiation from escaping into space and thus contributing to climate change. Even slight increases in average global temperatures can trigger shifts in weather patterns or extreme events such as record floods, violent storms or deadly heat waves – potentially increasing risks significantly.

    Current atmospheric CO2 concentration levels are the highest they’ve been in 650,000 years – an indicator of human-caused environmental degradation. Since the Industrial Revolution, human activities have contributed to increasing greenhouse gas concentrations through burning of fossil fuels and extensive deforestation activities.

    CO2 and other greenhouse gas emissions are projected to increase further, leading to further climate change due to energy use, economic development and population growth. This poses serious concerns as many experts recognize that current rates of energy usage, economic development and population expansion will lead to sustained climate change with potentially dramatic consequences.

    As our planet warms, glaciers and ice sheets melt, sea levels rise and disrupt natural ecosystems on Earth – impacting food production, water availability, coastal communities and many other aspects of life on our beautiful but fragile Earth. These changes have already had serious repercussions that are destabilizing ecosystems across our beautiful yet vulnerable world.

    Some impacts may be reversible, while many will not. According to the Intergovernmental Panel on Climate Change (IPCC), we are nearing “tipping points”, thresholds past which changes may accelerate irrevocably and become irreversible – including Arctic ice melt and Greenland ice sheet collapse and degradation of coral reefs. Most vulnerable people across the planet, especially economically disadvantaged and people of color will bear the brunt of these shifts.

    It’s our responsibility.

    Atmospheric change has long been driven by natural processes, including volcanic activity and changes to solar output, but they do not account for recent rises in global temperatures caused by human activities like fossil fuel burning, increasing ocean heat content, and shifting air circulation patterns.

    Over 97% of scientists agree that humans are the cause of climate change. Human activities, like burning fossil fuels (oil, gas and coal), create greenhouse gases which act like blankets around our planet and trap solar energy, warming global temperatures. Carbon dioxide levels used to fluctuate naturally due to volcanic activity or animal breathing out oxygen into their systems but since the Industrial Revolution humans have produced unprecedented quantities of greenhouse gases such as carbon dioxide that have contributed significantly to temperature rise worldwide.

    Human-caused climate impacts that we are currently witnessing include rising sea levels, shrinking mountain glaciers, increased Greenland and Antarctica ice melt rates and altered rainfall patterns; shifting rain-fall patterns; altered rain-to-sun ratios; altered rain-droplet distribution patterns and shifting flower/plant bloom times – impacts that were not anticipated by scientists earlier. Scientists’ projections will likely continue to accelerate.

    Climate change impacts all people worldwide, yet is already having devastating effects. Wildfires, hurricanes, flooding and drought are already occurring and endangering food production, homes and livelihoods; those most at risk include those living in poverty as well as communities that experience gender, racial or economic disparities.

    Good news is that it is indeed feasible for us to reduce emissions and limit global warming to 2 degrees Celsius or less with significant reductions in fossil fuel and other harmful chemical consumption. Unfortunately, however, Big Oil lobbyists and their supporters are doing all they can to sow doubt and delay meaningful climate action.

    Our planet needs our collective effort and action now more than ever; together we must enact policies to achieve rapid, deep and permanent reductions of greenhouse gas emissions required to secure its future.

  • The Carbon Culprit – Understanding the Role of CO2 in Climate Change

    The Carbon Culprit – Understanding the Role of CO2 in Climate Change

    The greenhouse gas carbon dioxide blankets Earth’s atmosphere, preventing heat energy from escaping. That extra heat raises temperatures, warming the planet and disrupting nature’s usual balance.

    This animation, by Carbon Brief, shows national responsibility for historical emissions. It ranks nations by their total cumulative CO2 emissions from fossil fuels and land use change since 1850, including those emitted under colonial rule.

    1. The Carbon Cycle

    Carbon is a vital element for all living organisms and is found in various forms throughout the natural world. The carbon cycle describes the continuous circulation of carbon between Earth’s reservoirs – the atmosphere, oceans and soil. Carbon atoms are constantly moving between these reservoirs through processes such as photosynthesis, respiration and decomposition of living organisms, and volcanic eruptions.

    As greenhouse gases, carbon dioxide and other GHGs trap radiant energy from the sun within the atmosphere, warming the planet by increasing its average temperature. This is known as the greenhouse effect and it is essential to the existence of life on Earth, but it can become dangerous if concentrations of GHGs increase too much.

    GHGs are emitted into the air when carbon-containing matter is combusted, such as when fossil fuels like coal, oil and gas are burned. This causes CO2 levels in the atmosphere to rise, which is then absorbed by the ocean and land, leading to a positive feedback loop that amplifies climate change.

    Normally, natural processes keep atmospheric CO2 levels in balance. However, since the onset of industrial times, human activities have caused a significant rise in CO2 levels. This is because burning fossil fuels releases carbon that’s been locked away in geological formations for millions of years, transferring it from the slow to the fast (biogenic) carbon cycle. This influx has led to excessive levels of atmospheric CO2 that the biogenic carbon cycle can’t cope with, and which is driving climate change.

    Figure 1 shows the long-term trend of atmospheric CO2 observed at Mauna Loa since 1958. While the trend is clearly upwards, there are also a series of wiggles within the data. These are caused by seasonal cycles in photosynthesis, which cause the levels of CO2 in the atmosphere to rise and fall each year.

    Human activity is causing CO2 levels to rise at a rate faster than they have in the past 3.6 million years, and this has triggered the climate change we are currently experiencing. This figure shows the total cumulative emissions of CO2 from human activities since 1850, broken down by country and source (in billions of tonnes). The breakdown includes fossil fuels, cement, land-use change and forestry.

    2. Fossil Fuels

    Fossil fuels are a group of non-renewable materials that can be burned to produce energy. They include coal, crude oil, natural gas and other hydrocarbons that formed from the fossilized remains of plants and animals.

    When fossil fuels are burnt they release carbon dioxide and other greenhouse gases into the atmosphere. These gases trap heat from the sun and cause the world to warm. They also disrupt the Earth’s natural climate processes. This is causing a number of problems, including ocean acidification, loss of biodiversity and severe weather events.

    In the United States, coal, oil and gas provide 81 percent of our energy. They are responsible for nearly three-fourths of the CO2 emissions from human activities since the beginning of the industrial revolution. Fossil fuels are a non-renewable resource, and waiting millions of years for new deposits to form is not an option. This means that we need to make a transition to renewable energy sources and increase efficiency in our existing buildings and vehicles.

    It’s important to understand who is responsible for emissions because of the global nature of our economy and the complex ways that countries trade with each other. Emissions accounts that take into account consumption give full responsibility to the people who use the products that are made with fossil fuels, and tend to reduce the total for major exporters. However, there are practical challenges to obtaining such accounts, which require detailed trade tables and have only been available for the years since 1990.

    A key issue is that countries themselves are arbitrary boundaries, created by accidents of history, geography and politics. This makes it difficult to compare the historical responsibility of different nations.

    One way of looking at this is to use a method called “normalisation”. This involves splitting total emissions into categories according to the population of each country. This allows the share of a country’s emissions to be compared across countries with very different populations.

    Carbon Brief has normalised country shares using the historical timeseries published by CDIAC and aggregated with other useful information by Our World in Data (OWID). The chart below shows the 20 largest contributors to cumulative emissions (1850-2021) and also breaks down the total into those from fossil fuel use and land-use change and forestry (green). A further chart shows these breakdowns for each of the years since 1990.

    3. Energy

    The energy we use to do work — like walking, cycling, driving cars and trucks, running factories and ships, and baking bread in ovens — depends on the chemical energy of fossil fuels. But this energy isn’t free — it comes with a cost in the form of greenhouse gas emissions.

    Historically, fossil fuels have been the primary source of human-caused CO2 emissions. But a growing proportion of global energy consumption now stems from renewables and nuclear power, which are less carbon-intensive than fossil fuels. The renewables and nuclear sectors also produce fewer other types of harmful greenhouse gases, such as methane, nitrous oxide and sulfur dioxide.

    It’s important to understand that there is a direct link between the total amount of CO2 humans release and the planet’s warming – and that it doesn’t matter if those emissions happen now or in the past. This is because the climate system is a long-term player, with impacts that persist far beyond our own lives.

    The carbon cycle has natural’sources’ and’sinks’ for CO2. Volcanoes belch CO2 into the atmosphere, but a broader system of plants, oceans, and soils absorb and store it. Over time, the carbon sinks replenish themselves, but the rapid pace of human activity has overwhelmed them.

    For this reason, the global climate system now has a ‘carbon budget’ that determines how much further the world can warm before it goes too far. This budget is the total amount of CO2 humans have already released into the air. If emissions continue at current levels, the budget for a two-thirds chance of keeping temperatures below 1.5°C would be used up within 10 years – and the remaining two-thirds chance in 2050.

    Countries can take steps to reduce their historical emissions by using renewable and nuclear energy sources, and reducing their transport and heating and cooling demand. They can also invest in clean energy technologies, such as carbon capture and storage, which involves capturing the CO2 from fossil fuels before they enter the atmosphere, and storing it deep underground at a suitable geologic formation.

    It’s also important to recognise that a country’s ranking in the chart above – and its per-capita ranking – depends on the methodology chosen. While Carbon Brief’s approach to normalising a country’s ranking by population is fairly straightforward, other methods can lead to markedly different results and should be considered carefully.

    4. Renewable Energy

    The rise in atmospheric CO2 is largely due to human activities. The burning of fossil fuels such as coal and oil, and deforestation have added a significant amount of heat-trapping greenhouse gases to the atmosphere. These gases trap the Sun’s heat in the atmosphere and change the climate.

    Scientists are working on ways to reduce these changes by developing renewable energy sources. One way is to turn carbon dioxide into a useful fuel substitute by using it as raw material in the production of biofuels like ethanol and biomass. Another method is to capture the CO2 produced when fossil fuels are burned and store it deep underground.

    These methods have the potential to slow, halt and even reverse global warming. But the key to a successful outcome will be implementing them on a large scale. This includes replacing a substantial proportion of cars with zero-emission vehicles, and providing access to clean energy for all, including remote, island and coastal communities.

    Renewables such as wind and solar photovoltaics (PV) are increasingly popular, and the technology continues to improve and get cheaper every year. They are a vital part of the solution to climate change, but they will need to be matched by increased deployment of nuclear power and other low-carbon technologies, along with better batteries to store energy.

    Observed changes in the Earth’s climate system, such as rising global air and ocean temperatures, melting of snow and ice, and long-term sustained reductions in regional weather patterns, are caused by extra heat being added to the atmosphere by humans through the use of fossil fuels, land-use change, agriculture, and deforestation. These human-caused inputs increase the concentration of heat-trapping greenhouse gases in the atmosphere.

    The US is responsible for the highest total cumulative emissions of CO2 since 1850, as shown in this animation from Carbon Brief, which also ranks countries by their contribution to the global total and separates them into emissions from fossil fuels and land-use change/forestry.

    A recent study has suggested that adding genetically modified E coli bacteria to sugar cane fields could make the plant produce three-fourths as much ethanol per hectare, and thus emit less CO2. This would reduce the need to harvest sugar cane for ethanol and cut the rate of deforestation in tropical nations where it is harvested.

  • Fossil Fuel Companies and Their Action Against Climate Change

    Fossil Fuel Companies and Their Action Against Climate Change

    Fossil fuel companies make billion-dollar profits from extracting and selling coal, oil and natural gas. They are also responsible for producing greenhouse gases, which cause climate change.

    Despite being aware of the risks, some fossil fuel companies are spreading misinformation and obstructing policies to move away from fossil fuels. They must be held accountable for their actions.

    Coal

    The global energy industry has a huge opportunity to make a rapid shift away from fossil fuels and towards clean renewables. But a new analysis by InfluenceMap shows that big oil companies are spending far more on advertising about climate change than they are on green investments.

    The world’s largest energy companies have publicly embraced the goal of reaching net zero greenhouse gas emissions by 2050. But this vision isn’t reflected in the decisions that they make with their money and lobbying power.

    Fossil fuel companies are spending billions of dollars on advertising about their “green” investments—and at the same time investing millions in new coal, oil and natural gas production. It’s a clear sign that they aren’t taking the threat of climate change seriously.

    It’s been more than a century since scientists first documented the link between fossil fuel burning and climate change. Now there is an overwhelming scientific consensus that Earth’s temperature is warming and human activities, particularly burning fossil fuels, are largely to blame. Global warming is already causing rising sea levels, devastating wildfires and destroying crops. The impacts are hitting low-income communities and people of color hardest.

    But the fossil fuel industry is trying to hide its role in this disaster. It’s denying the science and attempting to confuse the public. And it’s working to limit the reach of the legal system, which could force it to hand over years of internal documents that reveal what its executives knew about climate change and when they knew it.

    A lawsuit filed in Minnesota last fall aims to do just that. It accuses Exxon, Koch Industries and an industry trade group of deception, false advertising and consumer fraud. The lawsuit, like others across the country, alleges that fossil fuel companies have engaged in a campaign of misinformation to discredit and delay climate action. It’s a lawsuit that could force the oil companies to produce evidence of their misdeeds and expose their attempts to conceal them. It’s a process that could take years, but it’s a crucial one in the fight to protect our planet and the lives of people who depend on it.

    Oil

    Many of the world’s biggest fossil fuel companies, such as ExxonMobil, have come under scrutiny over their knowledge of climate change. The company was accused of spreading misinformation to protect its profits, and this has led to a series of lawsuits. In some cases, it is alleged that the company knew about climate change in the 1960s, and this evidence has been used to support claims that the company hid this information from the public.

    The company’s scientists were aware of the risk posed by burning fossil fuels, and they warned management that the company would need to take steps to reduce its emissions. However, they were told that this would have a negative impact on the company’s bottom line. This was despite evidence that the planet was warming and that humans were responsible for this, and a report by the Intergovernmental Panel on Climate Change in the 1990s recommended limiting future greenhouse gas (GHG) emissions to less than two degrees Celsius.

    In recent years, politicians and environmentalists have accused the company of delaying action on climate change by funding organisations that spread doubt about the science. It has also been alleged that it funded front organisations with neutral, scientific-sounding names. For example, the US House of Representatives Oversight Committee alleges that ExxonMobil funded the George C Marshall Institute, which was involved in a sham petition to President Bush to deny manmade global climate change.

    A number of lawmakers have called for an end to fossil fuel industry funding for groups that discredit climate science. They argue that such money is preventing the country from taking effective action to curb global warming and is harming the lives of poor people, particularly those in low-income communities.

    Despite this, it is important to recognise that not all fossil fuel companies are bad, and that some have taken a constructive approach towards tackling climate change. For instance, some have embraced the goal of becoming net zero carbon businesses by 2050.

    The overarching issue is that fossil fuel corporations have failed to address climate change adequately and are allowing a dangerous planetary crisis to escalate. As a result, policies that aim to limit climate change must be rigorously applied. Those policies must focus on reducing demand for fossil fuels, not simply lowering GHG emissions. This is why efforts that restrict fossil fuel production, such as eliminating oil and gas drilling on US public lands or banning hydraulic fracturing, are so important.

    Natural Gas

    Natural gas has been billed as a “cleaner” alternative to coal and oil because it produces significantly less climate-warming pollution when burned. Unfortunately, it also emits a substantial amount of greenhouse gases (GHGs) during its production and transmission. In addition, methane, the primary constituent of natural gas, is a potent GHG that traps heat in the atmosphere 28 to 36 times more effectively than carbon dioxide. Minimizing methane releases along the natural gas value chain is one of the most important things we can do to reduce its climate footprint.

    Natural gas is extracted from shale and other types of sedimentary rock by forcing water, chemicals and sand down a well under high pressure. This process, known as hydraulic fracturing or fracking, enables access to fossil fuels that wouldn’t be economically viable to produce using older technology. Since the late 1980s, fracking has become increasingly efficient and widespread as companies develop new technologies and obtain regulatory waivers. As a result, the United States has become the world’s largest producer of natural gas, displacing Russia.

    Once drilled, natural gas is sent through pipelines to locations where it will be used for electricity generation, heating homes and businesses, and as a raw material for various industrial processes. Demand varies daily and seasonally, so natural gas is stored in large volumes underground to be available when needed.

    The natural gas industry is committed to reducing its environmental impact through innovation, cultivating a diverse and inclusive workforce, and exceeding customer expectations. The AGA Playbook is an excellent resource for anyone interested in learning more about how the American natural gas industry is delivering on its commitment to sustainability, affordability and innovation.

    The United States is the second-largest GHG emitter, and most of our emissions come from burning fossil fuels. However, reducing U.S. GHG emissions alone will not be enough to mitigate the impacts of climate change. Significantly reducing global demand for fossil fuels by phasing out their combustion without carbon capture and storage or use, along with other GHG-reducing measures like energy efficiency and renewable energy, will be necessary.

    Tar

    As the world faces climate change, fossil fuel companies are trying to portray themselves as clean energy leaders. But the reality is they’re using their billions to fund climate denial and delay action. Now, lawsuits by coastal cities, Midwestern states watching “mega-rains” wreak havoc and fishing communities struggling with declining catches are demanding that they take responsibility for the damage their products cause.

    The fossil fuel industry is facing a reckoning. For decades, it has hidden evidence that burning its products is causing climate change and misleading the public about its effects. A growing field of research called attribution science links heat-trapping gases from the burning of fossil fuels to quantifiable changes in our climate — like rising temperatures, sea levels and ocean acidification. Several new lawsuits allege that ExxonMobil, the US’s largest oil company, engaged in a decades-long conspiracy to deceive customers and investors by funding groups with neutral, scientific-sounding names to deny the existence of manmade global warming.

    Exxon’s own scientists documented the effects of fossil fuel combustion on our planet’s climate, and in 1978, it even equipped one of its tankers with equipment to monitor air and water temperatures to track carbon dioxide emissions. But, year after year, its executives continued to invest in fossil fuels and ignore the mounting scientific warnings.

    Today, Exxon is facing a wave of lawsuits filed by cities and states across the country – all accusing it of hiding what it knew about climate change while pushing its products to consumers. Unlike the tobacco lawsuits, which were settled out of court in 2000, these cases are being prosecuted under a civil law known as the Racketeer Influenced and Corrupt Organizations Act (RICO). And they’re likely to go all the way to the Supreme Court.

    To avoid catastrophic climate change, the world needs to stop producing and consuming fossil fuels and transition to a net zero greenhouse gas (GHG) economy by 2050. Many of the world’s biggest oil and gas companies support these goals publicly, but their lobbying and spending suggest they have no intention of slowing down their fossil fuel production.

  • Green Hydrogen and the Energy Transition

    Green Hydrogen and the Energy Transition

    Green Hydrogen is hydrogen that is produced from low-carbon or renewable energy sources. It is renewable energy and can be produced at a cost comparable to fossil fuels. Green Hydrogen is a promising technology that has many applications. This article explores the advantages of green hydrogen and the impact it will have on the global energy transition.

    Renewable energy

    Green hydrogen is a clean fuel alternative to fossil fuels that leaves no greenhouse gas residue. It can be used at any time and in any weather and could help solve our current climate crisis. Green hydrogen is made by electrolyzing water to separate hydrogen from oxygen. This process can be powered by renewable energy.

    The demand for hydrogen is growing rapidly. The green hydrogen industry requires over 22,000 TWh of green electricity per year and requires more than 500 million tons of green hydrogen per year. The value chain for hydrogen is similar to that for fossil fuels, with upstream, midstream, and downstream elements.

    Renewable hydrogen is a useful fuel for a variety of uses, from making fertilizers to fuelling cars. It can also be used in the production of ammonia, a feedstock for fertilisers, and can be used as a fuel in ships. It is also a replacement for coal in the production of iron.

    Green hydrogen is produced with renewable energy and produces near-zero greenhouse gas emissions. Some projects are “off-grid”, while others are “on-grid” and contribute to the electricity supply. This additional demand can reduce the use of renewable energy in other sectors and increase the overall greenhouse gas emissions.

    In addition to storing energy from renewable sources, hydrogen is also a valuable fuel that can transport renewable energy to areas with high energy demand. Green hydrogen is a promising energy solution for a global transition to a net-zero emissions economy. Renewable energy from green hydrogen is essential to achieve the goals of the Paris Climate Agreement. This fuel can help decarbonize heavy industry, long haul freight, aviation, and shipping.

    Governments around the world are making major efforts to promote the hydrogen industry. The European Commission, whose goal is to make green hydrogen cheaper than conventional fuels, has set a 2050 target for hydrogen use in the industrial sector. This goal is also a significant step towards energy security in Europe.

    Governments are considering new regulations for green hydrogen. These regulations would require green hydrogen producers to build additional renewable electricity capacity, or to curtail their production in certain locations. These regulations would be in line with EU’s Renewable Energy Directive II (RED II).

    Cost parity with fossil fuels

    While the cost of green hydrogen remains higher than fossil fuels, the rising price of carbon is likely to drive up demand for the fuel. This means that the green hydrogen industry must become cost-competitive with fossil fuels. The key is to scale up the technology and bring the cost per kilogram of green hydrogen down to fossil fuel levels. If this can be achieved, then cost parity with fossil fuels could be reached by 2050.

    Green hydrogen is a renewable fuel that has a significant demand window. Its cost is lower in the Global South than in the Global North, which represents a significant opportunity for developing countries. There are several regions of the world with high potential to produce large amounts of green hydrogen at low cost, depending on the available renewable resources. Some of these regions include Africa and Asia. Some of these regions have geothermal resources and are ideally positioned to take advantage of this growing opportunity.

    Green hydrogen is an important component of a decarbonized economy, but there are a few challenges associated with this. It is currently much more expensive than grey hydrogen, so it will take some time to become cost-competitive. In the long run, however, green hydrogen should be as cheap as gray hydrogen. By 2030, it is likely to reach cost-parity with fossil fuels in some sectors. This will require a lot of effort, investment, and research, but there are many benefits to be gained.

    The hydrogen industry is expected to reach $183 billion by 2023. In 2017, it was valued at $129 billion. The industry is expected to grow at a rate of 9% every year. With the help of renewable energy, the cost of green hydrogen could fall to a price that is comparable to that of natural gas.

    Governments are actively promoting the development of green hydrogen. At the moment, 16 countries have published national hydrogen strategies, and eight have specific electrolyzer targets. There is no shortage of interest from governments across the world, and this is just the beginning. Governments should back these plans with appropriate policies and funding to make the transition to green hydrogen as seamless as possible.

    Sectors that will benefit from green hydrogen

    Hydrogen is a valuable energy storage resource that can be used for many industrial processes. It is currently used in the chemical industry to produce ammonia and fertilisers, as well as in the petrochemical industry to produce petroleum products. It is also finding its way into the steel industry, where environmental regulations are putting pressure on this industry to become more sustainable.

    There are many sectors that will benefit from green hydrogen. However, there are several major barriers to commercialization. One of the primary challenges is the development of zero-carbon electricity, which is required for hydrogen production at scale. Countries with high renewable electricity potential are best-positioned to take advantage of the emerging markets facilitated by green hydrogen.

    Green hydrogen can help countries reduce emissions, create jobs, and boost the economy. It will also help governments create a more just energy transition while improving competitiveness and opening new markets. It can also contribute to inclusive growth and local green jobs. Ultimately, the global economy will be stronger if we can make a more sustainable choice in energy.

    Governments, companies, and other stakeholders must collaborate to develop clean hydrogen technology. Governments must also work together to ensure that existing regulations are not unnecessary barriers to investment. Industry and government must also adopt common international standards to track the environmental impacts of hydrogen supply. The IEA has identified four near-term opportunities to boost the use of hydrogen. Implementing these solutions will help hydrogen achieve the scale it needs, while reducing risks for the private sector and governments.

    Green hydrogen is already being used in many industrial processes. For example, GE gas turbines have been using hydrogen blends for 30 years as an energy source. These hydrogen blends can reduce the CO2 emissions of natural gas by two percent. In addition, Japan is exploring co-firing green hydrogen-produced ammonia into coal-fueled boilers, which will cut GHG emissions from coal-fired power plants.

    Hydrogen can also reduce emissions in industries that are highly carbon intensive. In addition to reducing carbon dioxide and sulfur pollution, hydrogen fuels also support high-wage jobs, and create new export opportunities. However, there are concerns associated with hydrogen, which could limit the growth of its use in industrial processes.

    Impact on global energy transition

    The energy transition is underway, and hydrogen is widely seen as an important fuel for the future. Currently, hydrogen is used mostly in industry during oil refining and for synthetic nitrogen fertilizer production. It is relatively expensive compared to fossil fuels, but it is increasingly being promoted as a cleaner fuel that can address climate change. Its main disadvantage is its high greenhouse gas emissions, and some sources of hydrogen are more environmentally friendly than others. Blue hydrogen, on the other hand, is a new concept that refers to hydrogen that has low emissions.

    Green hydrogen has multiple benefits and can be produced using renewable resources. However, the economics of this energy source are very challenging. For instance, the cost of producing green hydrogen can vary by region. This makes it difficult to forecast the demand for green hydrogen. But the good news is that with continued technological advancements and economies of scale, the cost of production of green hydrogen will decline.

    To increase the adoption of green hydrogen, governments must adopt policies that incentivize investment in the industry. Moreover, they need to adopt policies that signal future changes. Furthermore, governments must also develop standards and regulations for green hydrogen and ensure compliance. Lastly, workers must be trained in the industry.

    Green hydrogen is a solution that can reduce global emissions and help achieve net-zero carbon emissions by 2050. It also has the potential to create a green alternative for industries that have difficulty embracing electrification. The idea is gaining popularity among governments. For instance, the European Union’s European Hydrogen Strategy was recently named the centerpiece of its Green Deal in July 2020. However, the European Union’s Green Deal has been folded into a fiscal stimulus response to the pandemic.

    As green hydrogen production grows, the geostrategic importance of countries that are best positioned to become significant green hydrogen exporters will rise. These historically energy-poor nations will become regional hubs for hydrogen trading. The European Union can influence the establishment of markets for hydrogen, and is already looking far across the world for sources. For example, countries in South America and Sub-Saharan Africa have significant potential to trade in green hydrogen.
