Use electricity generated from renewable energy sources to turn water into hydrogen fuel and lower greenhouse gas emissions from agriculture, transportation, and industry.
‘Green’ hydrogen originates from water molecules (H2O) that have been split using renewable energy. Its range of regenerative applications is large. Green hydrogen can generate electricity, drive industrial processes, or power vehicles. It can be a feedstock for turning carbon dioxide into liquid fuel or transforming atmospheric nitrogen into ammonia fertilizer. Green hydrogen can ‘fill in’ for solar and wind energy when the sun is down and the winds are calm. It can replace fossil fuels in sectors of the economy that are difficult to access with renewable energy. Despite these advantages, 99 percent of hydrogen used today originates from fossil fuels, such as methane, mostly because it has been cheaper to produce. The resulting carbon dioxide is released into the atmosphere. However, green hydrogen is poised for a global breakout thanks to ever-cheaper renewable power sources, mass production of equipment that generates hydrogen, and new subsidies. In 2022, $4.2 billion worth of green hydrogen was produced globally and is forecasted to exceed $130 billion by 2031 potentially.
