Abstract
Hydrogen is a carbon-free fuel that produces only water when energy is extracted from it. Decarbonization of our energy supplies can be accomplished in part by including hydrogen as an energy source, particularly in hard-to-abate sectors like steel and cement manufacturing. Nearly all the hydrogen used today is produced by splitting water or methane in chemical plants. However, there are natural processes that generate hydrogen in the subsurface, and some recent studies suggest that it could be present at an abundance that is relevant to future needs. This geologic hydrogen could be exploitable, but many challenges, both known and unknown, remain to be overcome. These include finding where hydrogen is produced and where it accumulates, how to prospect for hydrogen accumulations, and how to drill and recover subsurface hydrogen. I will present a research roadmap to help overcome these challenges and help us determine the best ways toward using geologic hydrogen.
