The...
- The National Science Foundation Division of Earth Sciences awarded Texas A&M Engineering Experiment Station $590,986 on August 1, 2026, under the CAREER program to advance mechanistic understanding of hydrogen generation from stimulated rock formations. The award funds laboratory experiments quantifying hydrogen production rates as reactive surface area varies, determining how mineral precipitation limits long-term hydrogen generation, evaluating whether chemical stimulation restores...
- This Project Grant award from the National Science Foundation (NSF) Engineering program (CFDA 47.041) provides $300,000 to Texas Tech University to develop a new, high-risk approach for carbon-negative hydrogen production from reactions between iron-rich rocks and water in the Earth's subsurface. The principal investigators will leverage geothermal energy and heat from exothermic reactions to self-sustain the hydrogen production process while simultaneously injecting CO2 to permanently store...
- The National Science Foundation Division of Earth Sciences awarded Woods Hole Oceanographic Institution $485,780 on September 1, 2026, under the Geosciences program to support postdoctoral research on hydrogen cycling through Earth's interior, with particular focus on oceanic volcanic hotspots. The postdoctoral fellow will analyze hydrogen and helium isotopic compositions alongside major, trace, and volatile element concentrations in submarine volcanic glasses and olivine-hosted melt...
- The National Science Foundation Office of Integrative Activities awarded Oklahoma State University $954,636 on August 1, 2026, under the Geosciences program (CFDA 47.050) to research biogenic hydrogen production in depleted oil reservoirs under geological carbon storage conditions. The project will characterize and quantify hydrogen production by microbial communities in actual reservoir rock, petroleum-produced water, and oil samples from depleted reservoirs in the Anadarko Basin of Oklahoma....
- This $710,000 Project Grant awarded by the National Science Foundation's (NSF) Engineering program (CFDA 47.041) will fund a multi-year research project at the University of Nebraska-Lincoln to advance the understanding of naturally occurring hydrogen deposits in the Midcontinent region of the United States. The key objectives of the project are to: 1) elucidate the transport and accumulation of natural hydrogen in soils and rocks through laboratory testing and field monitoring, 2) identify...
- The National Science Foundation Division of Ocean Sciences awarded the University of Southern California $753,971 on October 1, 2025, under the Geosciences program (CFDA 47.050) to investigate enzyme stability in deep subsurface sediments and its role in microbial community assembly. The research tests the hypothesis that unusually stable enzymes enable microbes living in ocean floor sediments to survive across timescales of decades to millennia, compared to microbial turnover in hours or days...
- The National Science Foundation Office of Integrative Activities awarded Colorado School of Mines $300,000 on August 15, 2026, under the Geosciences program (CFDA 47.050) to advance fundamental understanding of coupled physical and chemical processes controlling reactive flow in fractured rock. The project combines laboratory experiments with computational models to determine how fracture heterogeneity influences mineral dissolution and precipitation, permeability evolution, and fluid flow...
- This Project Grant award from the National Science Foundation (NSF) Division of Polar Programs (CFDA 47.078) provides $814,685 to the University of California Irvine (UC Irvine) to analyze molecular hydrogen (H2) in an ice core from Summit, Greenland. The goal is to reconstruct atmospheric changes in H2 over the past millennium, which will establish a baseline to assess how human activities have influenced atmospheric H2 since the preindustrial era. The research involves drilling a new ice core,...
COLLABORATIVE RESEARCH: RAPID: TIME-SENSITIVE OPPORTUNITY TO ACCESS 1.2 BILLION-YEAR-OLD BRINES TO QUANTIFY MICROBIAL HYDROGEN CYCLING IN THE DEEP SUBSURFACE -WHEN WATER REACTS WITH MANY ROCKS DEEP IN EARTH?S SUBSURFACE, HYDROGEN CAN BE PRODUCED, PROVIDING FUEL FOR MICROORGANISMS THAT UTILIZE THIS DEEP-ROOTED GEOLOGICAL HYDROGEN AS AN ENERGY SOURCE. WHILE GEOLOGICAL HYDROGEN HAS BEEN PROPOSED AS A TRANSFORMATIVE SOURCE OF ENERGY FOR HUMAN USE, THE CHEMICAL AND BIOLOGICAL REACTIONS THAT PRODUCE AND CONSUME HYDROGEN IN THE SUBSURFACE ARE POORLY UNDERSTOOD, LARGELY DUE TO DIFFICULTIES IN ACCESSING THESE DEEP ENVIRONMENTS. THIS PROJECT WILL UTILIZE A UNIQUE OPPORTUNITY TO SAMPLE FROM ONE OF THE DEEPEST GOLD MINES IN THE WORLD TO PROVIDE A UNIQUE WINDOW INTO DEEP GEOLOGICAL HYDROGEN PROCESSES. THIS MULTIDISCIPLINARY STUDY OF A HYDROGEN-BASED ANCIENT BRINE ECOSYSTEM LINKS DISCIPLINES FROM GEOPHYSICS TO BIOLOGY. THIS PROJECT DIRECTLY BENEFITS SOCIETY BY PROVIDING INFORMATION RELEVANT TO THE DEVELOPMENT OF GEOLOGICAL HYDROGEN AS AN ENERGY SOURCE, AS WELL AS INFORMATION ON THE LIMITS AND ORIGIN OF LIFE ON EARTH AND FOR THE EXPLORATION OF LIFE HERE AND ON OTHER WORLDS. DEEP GOLD MINES IN SOUTH AFRICA OFFER UNPARALLELED ACCESS TO DEEP, ANCIENT BRINE WHERE GEOLOGICAL HYDROGEN IS ABUNDANT. PRODUCTION OF HYDROGEN BY ROCK-WATER INTERACTIONS IN THESE DEEP ENVIRONMENTS COULD BE ENHANCED BY FREQUENT EARTHQUAKE ACTIVITY. THIS PROJECT WILL DRILL INTO A DEEP BRINE IN THE MOAB KHOTSONG MINE AND COLLECT ROCK AND FLUIDS TO MEASURE THE PRODUCTION OF HYDROGEN FROM ROCK-WATER INTERACTIONS, AND ITS SUBSEQUENT CONSUMPTION BY MICROBES. THE HYDROGEN-CYCLING MICROBES WILL BE IDENTIFIED AND CHARACTERIZED. RATES OF HYDROGEN CONSUMPTION WILL BE ASSESSED AT MULTIPLE SCALES RANGING FROM INDIVIDUAL CELLS IN FRACTURES UP TO THE ENTIRE BIOSPHERE TO DETERMINE THE EXTENT TO WHICH MICROBES INFLUENCE HYDROGEN AVAILABILITY. THESE DATA WILL BE USED TO EVALUATE WHETHER DEEP HYDROGEN IS A MAJOR CONTRIBUTOR TO ENERGY CAPTURED BY MICROBES, WHETHER SUBSURFACE MICROBIAL ACTIVITY INCREASES IN RESPONSE TO HYDROGEN AVAILABILITY, AND WHETHER SEISMIC ACTIVITY TRIGGERS PULSES OF MICROBIAL ACTIVITY BY RELEASING ABIOTIC HYDROGEN. THE PROJECT WILL DRILL FROM A MINE PASSAGE AT ~3 KM DEPTH TO REACH A HYDROGEN-RICH BRINE AND RECOVER HARD ROCK AND BRINE FLUID FOR GEOLOGIC, GEOCHEMICAL, AND MICROBIOLOGICAL ANALYSES. THE COMBINED DATA OF SEISMIC ACTIVITY, CHEMISTRY, AND CONTINUOUSLY SAMPLED MICROBIAL COMMUNITY AND ACTIVITY DATA WILL BE INTEGRATED TO PROVIDE A COMPREHENSIVE VIEW OF HYDROGEN CYCLING IN THE SUBSURFACE. THIS AWARD REFLECTS NSF'S STATUTORY MISSION AND HAS BEEN DEEMED WORTHY OF SUPPORT THROUGH EVALUATION USING THE FOUNDATION'S INTELLECTUAL MERIT AND BROADER IMPACTS REVIEW CRITERIA.- SUBAWARDS ARE NOT PLANNED FOR THIS AWARD.
