Hydrogen: Climate Risks and Rewards with Ilissa Ocko

Ilissa Ocko, a Senior Climate Scientist at the Environmental Defense Fund, believes that hydrogen can play a critical role in decarbonizing hard-to-abate sectors such as heavy industry and transportation. However, she emphasizes that hydrogen production through fossil fuel-based processes can result in significant greenhouse gas emissions, negating the climate benefits of using hydrogen. The development of low-carbon hydrogen production methods, such as through renewable energy sources or carbon capture and storage, is crucial to realize the full potential of hydrogen as a climate solution.
