Declining renewable energy costs have sparked a renewed interest in green hydrogen, which has the potential to decarbonize sectors that are harder to electrify.
Because hydrogen doesn't occur by itself on Earth, it must be separated from other elements, such as oxygen in water. Electrolysis is the process of using electricity from renewable energy to extract hydrogen from water.
Dr. Ben Wiley, Duke University Professor of Chemistry, joins Climate Now to explain hydrogen electrolysis, where it makes sense to integrate into the energy economy, and the technology he is helping develop to improve its productivity.
