A "Lunch & Learn" Webinar with Dr. Thomas Darrah
CTO of Koloma
Join us for an exclusive deep dive into the next frontier of clean energy. While the world has focused on making hydrogen, a revolutionary shift is underway: finding it. Geologic hydrogen—naturally occurring deposits trapped beneath the Earth's surface—could provide a carbon-free, baseload energy source at a fraction of the cost of manufactured alternatives.
Dr. Thomas Darrah, CTO of Koloma. Dr. Darrah is a world-renowned isotope geochemist and a leading pioneer in the geologic hydrogen space. Under his technical leadership, Koloma has emerged as a frontrunner in identifying and extracting "gold" hydrogen. He will share his insights on the science, scalability, and timeline for hydrogen integration.
Dr. Thomas Darrah serves as Chief Technical Officer, overseeing natural hydrogen exploration and intellectual property and technology development. Prior to joining Koloma, Dr. Darrah was a Full Professor of Earth Sciences at Ohio State University. Dr. Darrah is an internationally recognized scholar that has made significant contributions to his field through research funded by the National Science Foundation, US Department of Defense, US Department of Energy, the National Institute of Environmental Health Sciences, NASA, and others. He has held several leadership positions within his field, including Vice President and President of the Geologic Society of America Division for Geology and Health, and Executive Director of the Global Water Institute. Dr. Darrah obtained a Ph.D. in Geology from the University of Rochester and has 20 years of experience specializing in gas geochemistry and subsurface geoscience.
