Hydrogen's unique role in a zero-carbon energy system

The first episode of season two of Climate Sense, hosted by Samantha Gross, is all about hydrogen. Hydrogen will have an important role in a zero carbon energy system, enabling decarbonization of energy end-uses that cannot easily use electricity. Hydrogen is made today by splitting molecules of either water or natural gas, using significant energy in the process, so it's important to reserve hydrogen for its highest and best uses. However, future production of geologic hydrogen could be game-changing, giving us a zerocarbon fossil fuel. Show notes and transcript Climate Sense is part of the Brookings Podcast Network.
