Germany

Germany invested €9 billion to construct 5 GW of electrolyzer capacity by 2030.

China

Sinopec aimed to generate 500,000 tonnes of green hydrogen by 2025. Researchers from the Harvard China Project indicated that hydrogen generated from wind energy could provide a cost-effective alternative for coal-dependent regions like Inner Mongolia. As part of preparations for the 2022 Winter Olympics a hydrogen electrolyser, described as the "world's largest" began operations to fuel vehicles used at the games. The electrolyser was powered by onshore wind.

United Kingdom

In March 2021, a proposal emerged to use offshore wind in Scotland to power converted oil and gas rigs into a "green hydrogen hub" which would supply fuel to local distilleries. In June 2021, Equinor announced plans to triple UK hydrogen production. In March 2022 National Grid announced a project to introduce green hydrogen into the grid with a 200m wind turbine powering an electrolyser to produce gas for about 300 homes. Vattenfall planned to generate green hydrogen from a test offshore wind turbine near Aberdeen in 2025.

United States

The federal Infrastructure Investment and Jobs Act, which became law in November 2021, allocated $9.5 billion to green hydrogen initiatives. In 2021, the U.S. Department of Energy (DOE) was planning the first demonstration of a hydrogen network in Texas. The department had previously attempted a hydrogen project known as Hydrogen Energy California. Texas is considered a key part of green hydrogen projects in the country as the state is the largest domestic producer of hydrogen and has a hydrogen pipeline network. In 2020, SGH2 Energy Global announced plans to use plastic and paper via plasma gasification to produce green hydrogen near Los Angeles. In 2021 then New York governor Andrew Cuomo announced a $290 million investment to construct a green hydrogen fuel production facility. State authorities backed plans for developing fuel cells to be used in trucks and research on blending hydrogen into the gas grid. In March 2022 the governors of Arkansas, Louisiana, and Oklahoma announced the creation of a hydrogen energy hub between the states. Woodside announced plans for a green hydrogen production site in Ardmore, Oklahoma. The Inflation Reduction Act of 2022 established a 10-year production tax credit, which includes a $3.00/kg subsidy for green hydrogen.

Australia

In 2020, the government fast-tracked approval for the world's largest planned renewable energy export facility in the Pilbara region. In 2021, energy companies announced plans to construct a "hydrogen valley" in New South Wales at a cost of $2 billion to replace the region's coal industry. As of July 2022, the Australian Renewable Energy Agency (ARENA) had invested $88 million in 35 hydrogen projects ranging from university research and development to first-of-a-kind demonstrations. In 2022, ARENA expected to close on two or three of Australia’s first large-scale electrolyser deployments as part of its $100 million hydrogen deployment round.

Canada

World Energy GH2’s Project Nujio'qonik aims to be Canada’s first commercial green hydrogen / ammonia producer created from three gigawatts of wind energy on the west coast of Newfoundland and Labrador, Canada. Nujio’qonik is the Mi’kmaw name for Bay St. George, where the project is proposed. Since August 2022, the project has been undergoing environmental assessment according to regulatory guidelines issued by the Government of Newfoundland and Labrador. Project Nujio'qonik is expected to produce first green hydrogen in late-2025 and start international export in 2026.

Chile

Chile's goal to use only clean energy by the year 2050 includes the use of green hydrogen. The EU Latin America and Caribbean Investment Facility provided a €16.5 million grant and the EIB and KfW are in the process of providing up to €100 million each to finance green hydrogen projects.

India

Reliance Industries announced its plan to use about 3 gigawatts (GW) of solar energy to generate 400,000 tonnes of hydrogen. Gautam Adani, founder of the Adani Group announced plans to invest $70 billion to become the world's largest renewable energy company, and produce the cheapest hydrogen across the globe. The power ministry of India has stated that India intends to produce a cumulative 5 million tonnes of green hydrogen by 2030. In April 2022, the public sector Oil India Limited (OIL), which is headquartered in eastern Assam’s Duliajan, set up India’s first 99.99% pure green hydrogen pilot plant in keeping with the goal of “making the country ready for the pilot-scale production of hydrogen and its use in various applications” while “research and development efforts are ongoing for a reduction in the cost of production, storage and the transportation” of hydrogen.

Mauritania

Mauritania launched two major projects on green hydrogen. The NOUR Project would become one of the world’s largest hydrogen projects with 10 GW of capacity by 2030 in cooperation with Chariot company. The second is the AMAN Project, which includes 12GW of wind capacity and 18GW of solar capacity to produce 1.7 million tons per annum of green hydrogen or 10 million tons per annum of green ammonia for local use and export, in cooperation with Australian company CWP.

Namibia

Namibia has commissioned a green hydrogen production project with German support. The 10 billion dollar project involves the construction of wind farms and photovoltaic plants with a total capacity of 7 (GW) to produce. It aims to produce 2 million tonnes of green ammonia and hydrogen derivatives by 2030 and will create 15,000 jobs of which 3,000 will be permanent.

Oman

An association of companies announced a $30 billion project in Oman, which would become one of the world's largest hydrogen facilities. Construction was to begin in 2028. By 2038 the project was to be powered by 25 GW of wind and solar energy.

Portugal

In April 2021, Portugal announced plans to construct the first solar-powered plant to produce hydrogen by 2023. Lisbon based energy company Galp Energia announced plans to construct an electrolyser to power its refinery by 2025.

Saudi Arabia

In 2021, Saudi Arabia, as a part of the NEOM project, announced an investment of $5bn to build a green hydrogen-based ammonia plant, which would start production in 2025.

Spain

In February 2021, thirty companies announced a pioneering project to provide hydrogen bases in Spain. The project intended to supply 93 GW of solar and 67 GW of electrolysis capacity by the end of the decade.

United Arab Emirates

In 2021, in collaboration with Expo 2020 Dubai, a pilot project was launched which is the first "industrial scale", solar-driven green hydrogen facility in the Middle East and North Africa."
