RFI on Geologic Hydrogen Resource Exploration

the recoverable reserves of hydrogen from natural accumulation or available through stimulation. These approaches will accelerate the discovery and economic evaluation of these resources and inform management steps needed to harness them. ARPA-E is soliciting information for how the agency can foster innovation in technologies and methodologies that can accomplish the following goals: 1. Produce a suite of exploration technologies specific to detecting either naturally occurring subsurface hydrogen concentrations or viable formations for hydrogen stimulation on land and offshore; 2. Increase the accuracy and precision of detection for either naturally occurring subsurface hydrogen concentrations or viable formations for hydrogen stimulation; 3. Reduce the cost of exploration efforts for either naturally occurring subsurface hydrogen concentrations or viable formations for hydrogen stimulation; 4. Accelerate the discovery process of either naturally occurring subsurface hydrogen concentrations or viable formations for hydrogen stimulation; 5. Define the geologic processes surrounding production of naturally occurring subsurface hydrogen through either serpentinization or radiolysis of water; 6. Quantify the recharge of hydrogen reservoirs from hydrogen generative processes of naturally occurring subsurface hydrogen through either serpentinization or radiolysis of water; and 7. Inform resource prediction, site management, economic returns, subsurface engineering efforts, environmental impact and mitigation actions through better characterization and monitoring.
