In a groundbreaking research project at the Jackson School of Geosciences in Austin, researchers are delving into the realm of geologic hydrogen production. By exploring natural catalysts contained in iron-rich rocks, the team aims to generate hydrogen gas without the emission of carbon dioxide, offering a sustainable solution for the energy transition. This endeavor, part of a $20 million initiative by the U.S. Department of Energy, focuses on leveraging 'serpentinization,' a natural geologic process, to release hydrogen from rocks. Led by Toti Larson and Esti Ukar, the project aims to facilitate this process at lower temperatures, making it more accessible for current technology. Successful lab tests have laid the foundation for scaling up experiments and exploring a variety of iron-rich rock types found throughout North America, including basalts, banded iron formations, and ultramafic rocks. With the potential to revolutionize hydrogen production and contribute to carbon neutrality, this research holds promise for a more sustainable energy future.
