Dr. Grant S. Bromhal is Acting Director of the Mineral Sustainability Division. He is leading a team to facilitate an environmentally, economically, and geopolitically sustainable supply chain of critical minerals, from upstream through midstream to downstream, and numerous associated industries, all while protecting our environment. He comes from the National Energy Technology Laboratory (NETL), where he is a Senior Fellow focusing on Geological and Environmental Sciences. In that role, he leads a team that conducts novel research related to carbon storage, unconventional oil and gas recovery, enhanced oil recovery, enhanced geothermal systems, and other related issues. Dr. Bromhal is the Technical Director of the Science-informed Machine Learning for Accelerating Real-Time Decisions in Subsurface Applications (SMART Initiative). Dr. Bromhal was also the Technical Director of the National Risk Assessment Partnership (NRAP), work for which he and his collaborators won, in 2017, an R&D 100 award for novel software development. He has been a research engineer at NETL for more than 20 years. During that time, he has been a Team Lead in Predictive Geosciences; the U.S. DOE’s technical representative on the Multiagency Collaboration (MAC) on Unconventional Oil and Gas; and a member of the DOE working group on well integrity in response to the Aliso Canyon incident. Dr. Bromhal earned his Ph.D. in Civil and Environmental Engineering from Carnegie Mellon University and his BS/BA degree in Civil Engineering and Math from West Virginia University. He is the recipient of the 2007 Hugh Guthrie Award for Innovation at NETL, the 2010 U.S. Geological Survey Director’s Award for Exemplary Service to the Nation, and the 2011 U.S. Department of Energy Secretary’s Achievement Honor Award.
