Description (excerpt):
Renewable hydrogen (RH2), produced from renewable feedstocks, can replace fossil fuels to help decarbonize some of the heaviest polluting and hardest-to-electrify sectors, such as industrial processes and maritime shipping. However, recent research underscores the risk of hydrogen emissions— the hydrogen molecules that we release into the atmosphere— in warming the climate.
Research from the Environmental Defense Fund and others shows strong climate benefits when using RH2 made from renewable electricity and water in place of fossil fuels, but those benefits vary depending on how much hydrogen is emitted into the atmosphere. The climate benefits from a well-regulated, clean, and renewable hydrogen
economy outweigh the warming impact of hydrogen emissions, but we can maximize the
benefits by minimizing hydrogen emissions.
