The Stimulate Utilization of Plentiful Energy in Rocks Through High-Temperature Original Technologies (SUPERHOT) program supports the small-scale research and development of technologies to enable production of geothermal energy from super-hot reservoirs by developing innovative methods of heat extraction through new designs and materials, with a focus on scalable Enhanced Geothermal Systems (EGS) and Advanced Geothermal Systems (AGS) (e.g., closed loop).
This Amended Determination follows the addition of new project milestones, teaming partners, and project locations to support the project team's small-scale research and development activities of a high-temperature sliding sleeve to increase energy recovery in enhanced geothermal systems (EGS) by 200 percent to 500 percent by increasing the contact area between the connected fracture system and the reservoir rock matrix.
The Catalytic Application Testing for Accelerated Learning Chemistries via High-throughput Experimentation and Modeling Efficiently (CATALCHEM-E) program supports the small-scale research and development of heterogeneous catalysts, solid materials that reduce the inherent energy needed to drive industrial-scale chemical reactions responsible for making everyday products and commodities.
This Fourth Amended Determination follows the approval of additional funding, extended period of performance, a new project team member, and additional project milestones to support the project team's small-scale research and development activities to further advance a chip-level direct two-phase impingement jet cooling solution to enhance overall thermal performance while reducing pumping power under the Cooling Operations Optimized for Leaps in Energy, Reliability, and Carbon Hyperefficiency for Information Processing Systems Program (COOLERCHIPS) Program.
