How Hydrogen Fuel Works:

Green Hydrogen: A Master in the Clean Energy Revolution

Green Hydrogen: Hydrogen fuel is typically used in two primary ways:

  1. Fuel Cell: A hydrogen fuel cell is an electrochemical device that converts hydrogen and oxygen into electricity and heat. This process produces electricity without combustion and releases only water and heat as by-products. Fuel cells are used to power vehicles, buses, trains, and even stationary power sources.
  2. Combustion of Hydrogen: Hydrogen can also be combusted directly in internal combustion engines, similar to gasoline and diesel engines. Although this method is less efficient and may produce some emissions, it is cleaner than fossil fuels because it is mostly water vapor and has limited pollutant emissions.

Green Hydrogen: Difference Between Hydrogen Engine:

  • Fuel Cell: These devices produce electricity through an electrochemical reaction. Because they are highly efficient and do not produce harmful emissions, they are widely used in electric vehicles such as hydrogen fuel cell cars.
  • Internal Combustion Engines: These engines burn hydrogen directly to produce mechanical work. Although they are less efficient and produce fewer emissions, they are still cleaner than traditional internal combustion engines running on gasoline or diesel.

Countries using hydrogen fuels vehicle

When I last updated my knowledge in 2023, several countries had already started using hydrogen fuel cell vehicles and were actively promoting the adoption of this technology. Please note that things may have changed since then. However, here are some countries that were early adopters of hydrogen fuel cell vehicles:

11 Countries Moving Toward a Green Hydrogen Economy

Renewable hydrogen is still in its infancy, but its potential is huge and several countries are in the driver’s seat.

On this month’s little-known National Hydrogen and Fuel Cell Day, Air Liquide has prepared a special gift for the United States: The French industrial giant will produce renewable liquid hydrogen at a planned facility near Las Vegas. announced plans to do so.The company announced that its facility will have a liquid hydrogen production capacity of 30 tons per day. Most of this will go to California, where 200 hydrogen filling stations are planned by 2025.

“Green hydrogen appears to be at a potential tipping point,” said Ben Gallagher, carbon and emerging technologies expert at Wood Mackenzie Power & Renewables. “There’s definitely something in the air.”

TOP STORIES Investors and policymakers are starting to take notice. Green hydrogen is still in its infancy, but here are 10 countries that are taking steps to be at the forefront of developments that could become an important energy source in the future.


Until now, Australia has had little presence in the green hydrogen market. But it wants to significantly expand its involvement in replacing fossil fuel exports with alternative fuels based on the country’s abundant renewable energy resources.
For example, Siemens this month joined a partnership to develop a 5 GW combined solar and wind project designed to boost renewable hydrogen production.
Possible destinations for Australia’s green hydrogen are Japan and South Korea. “Typically we would look for countries that are energy importers and are looking for low-emission fuels,” said Paul Graham, chief energy economist at the Commonwealth Organization for Scientific and Industrial Research.


Canada sees potential in the future green hydrogen market, not only as a producer of gas based on abundant renewable resources, but also as a fuel cell manufacturer. The federal ministry, Natural Resources Canada, outlined the possibility in a paper this month.
“Building on public and private sector collaboration and investment over the past several decades, Canada has a thriving hydrogen and fuel cell sector with export markets, including global leader Ballard Power Systems. and Hydrogenics,” the paper said.
Ballard Power Systems made headlines last year when Chinese conglomerate Weichai Power invested $163 million to acquire a 19.9% ​​stake in the company.


WoodMac’s Gallagher said the Chinese government sees green hydrogen, in addition to electric vehicles, as having the potential to decarbonize transportation. The country’s goals include 5,000 fuel cell vehicles by 2020 and 1 million by 2030.
Hydrogen vehicles are also exempt from tax. And Wuhan, the capital of central China’s Hubei province, is expected to become a hydrogen city by 2025, with up to 100 filling stations capable of accommodating around 5,000 fuel cell vehicles. The greater Wuhan region will be producing components for fuel cells and other elements of the hydrogen economy,” Gallagher said.


Green hydrogen was all the rage in France a year ago. In June 2018, then-Minister of the Environmental and Inclusive Transition Nicolas Hulot announced plans to invest 100 million euros ($117 million) in hydrogen technology, aiming to make France a world leader in the field. promised.
Meanwhile, Hydrogen de France (HDF) announced that it will invest €90 million in a hydrogen project in French Guiana. Now that Huro is no longer in government, there has been silence regarding the HDF project. But that doesn’t mean France’s interest in green hydrogen has waned.
In September, the country’s first hydrogen-fueled passenger bus was deployed, and this month the Auvergne-Rhône-Alpes region will deploy 1,000 hydrogen vehicles and 15 electrolyzers, to name just two recent advances. An investment of 100 million euros was promised.


Martin Habrutzel, head of strategy at Siemens Australia, said Germany saw potential for using hydrogen in “a variety of applications, including transport and industrial decarbonization.”
Already a pioneer in the development of hydrogen technology, the country is set to step up its game with plans to build 20 research institutes with a total budget of €100 million (US$110 million), to be announced in the summer. It is said that
Inga Posch, Managing Director of FNB Gas, the umbrella organization for German gas network operators, said: “Hydrogen is currently one of the hottest topics in the country’s energy transition.” ” he told Bloomberg in August


A head of all countries Japan is probably the most advanced green hydrogen market in the world, “especially in terms of hydrogen imports for domestic uses such as transportation,” Habrutzel said.
Thanks to the efforts of automakers such as Toyota and Honda, the country is leading the way in the development of hydrogen fuel cell vehicles.
And politicians are keen to promote green hydrogen as a replacement for liquefied natural gas, which Japan imports more than any other country. Last month, the company announced a global action plan to add 10,000 gas stations over the next 10 years.


Norway has great potential to produce hydrogen from hydropower and has pioneered the use of fuel cells on ferries. Earlier this year, the country also had the dubious honor of becoming the first country in the world to report an accident at a hydrogen filling station.
Nell Hydrogen, which operates the gas station, acted quickly to share information and determine the cause of the accident that injured two people.
Michela Bortolotti, communications manager for industry association Hydrogen Europe, said the event should not be an obstacle to the commercialization of hydrogen. “In many cases, hydrogen is safer than the fuels we currently use to power our cars,” she says.

South Korea

The Norwegian gas station incident is not the only safety setback plaguing the emerging green hydrogen industry this year. In May, a hydrogen storage tank exploded at a government research facility in Gangneung, South Korea, killing two people and injuring six others.
The explosion raised concerns about South Korea’s ambitious hydrogen introduction plan, which plans to have 850,000 fuel cell cars on the road by 2030, up from 3,000 this year.
The government also plans to provide $1.8 billion in subsidies for vehicles and gas stations, but Reuters reported last month that gas stations are still not economically viable.


Although the UK appears increasingly isolated from its European trading partners, it enjoys one of the world’s largest markets for offshore wind power. Rely on renewable hydrogen to reduce gas imports and accelerate the decarbonization of the heating sector.
Last month, the UK government announced a £12 billion ($15 billion) plan to build 4 gigawatts of offshore wind power to produce renewable hydrogen in the early 2030s.
Meanwhile, the UK’s hydrogen concessions are attracting international attention. This month, chemical giant Linde paid £38 million ($46 million) for a 20% stake in listed technology developer ITM Power.


New Delhi:
Ministry of New and Renewable Energy has introduced norms for green hydrogen production in the country. In a statement, the ministry defined green hydrogen as hydrogen obtained from renewable energy sources through electrolysis or biomass conversion. This definition also includes green energy stored in energy storage systems.
Additionally, the government stipulates that CO2 emissions per kilogram of hydrogen produced must not exceed 2 kilograms of carbon dioxide equivalent.
When produced by electrolysis, “abiotic greenhouse gas emissions from water treatment, electrolysis, gas purification, drying, and hydrogen compression are estimated at 2 kilograms of carbon dioxide equivalent (kg CO2) per kilogram of hydrogen. ), measured as the average over the previous 12 months.


While the United States as a whole is hardly worth mentioning when it comes to green hydrogen development, one state, California, is striving to become a world-leading market.
California’s interest in hydrogen is driven by aggressive decarbonization goals, including eliminating all diesel or natural gas buses by 2040, and the presence of some of the industry’s best-known technology developers. It is also promoted by
First up is Bloom Energy, a Silicon Valley-based fuel cell maker. But the company still struggles to achieve a goal that no publicly traded fuel cell company has hitherto achieved: annual profits.
