## What the grant funds

Request for Information (RFI): Stimulating Geochemical Reactions in the Subsurface for in-situ Generation of Hydrogen and Helium Production This is a Request for Information (RFI) only. This RFI is not accepting applications for financial assistance. The purpose of this RFI is solely to solicit input for ARPA-E consideration to inform the possible formulation of future programs. The purpose of this RFI is to solicit input for a potential future ARPA-E research program focused on enabling technical advances which could lead to subsurface chemical reactors and gas separations. ARPA-E is seeking information to test the hypothesis that the subsurface can be used as a reactive environment to produce hydrogen at $1/kg, per DOE’s Hydrogen Shot target , and helium with no carbon emissions. Subsurface reactions have and do occur every day without human intervention, ranging from the mundane like abiogenic methane formation to the exotic like nuclear fission. The subsurface has a number of features which could make it amenable to performing chemical synthesis including hot temperatures (200-400+°F), high pressures, and catalytically relevant metals contained in rocks. It is already known that geothermal heat is a significant source of renewable energy. There are several initiatives devoted to resource discovery and development through the DOE’s Geothermal Technology Office which aim to use this thermal energy to produce electricity or to provide hot water and space heating. However, it may be possible to use this thermal energy for chemical synthesis. Typical deep geothermal temperature ranges (175-400°F) overlap well with chemical and other high-temperature processes. In addition to warm thermal conditions, the subsurface is characterized by high pressures. The pressure gradient at depth is related to hydrostatic pressure change (10 kPa/m). Pressures relevant to typical industrial processes can be accessed at depths that are well within the normal range of subsurface activities today. For example, a typical Haber Bosch process is done at pressures of 400 atm: approximately the same pressure found at a depth of 2 km. Finally, rocks may contain metals which are catalytically relevant for several industrial chemical processes. Nickel-iron alloys are frequently found in rocks and both nickel and iron are common catalytic metals in industrial processes.
