RFA for Solar/Geothermal Hybrid Thermal Energy Storage Modeling: Cooperative Research and Development Final Report, CRADA Number CRD-16-646
- National Renewable Energy Laboratory (NREL), Golden, CO (United States)
Hyperlight Energy is an innovative concentrated solar power (CSP) company whose business charter is to commercialize a disruptively low-cost, CSP collector system that is ultimately for providing heat for solar thermal/geothermal hybrid power plants, process heat applications (e.g., enhanced oil recovery), and solar thermal power generation. Hyperlight's CSP collector system utilizes a linear Fresnel reflector (LFR) configuration. This LFR configuration consists of mirrors mounted in low-cost, precision plastic extrusions, which are integrated into raft assemblies and floated on low-cost, sealed waterbeds. Hyperlight's CSP collector technology has been developed under private equity investment, government grant and commercial funding. Hyperlight has been awarded a 1.5-million DOE COLLECTS contract with an additional 1.6 million in matched funds from private investment and the California Energy Commission. This DOE project will support the final steps of product development for bulk commercialization and deployment of the Hyperlight CSP collector system. The work will culminate in a final operational deployment at a commercially relevant site. Several such site options are currently under evaluation, including two geothermal sites. Hyperlight identified a very low-cost way to put renewable energy electrons on the grid at peak times, upgrading underutilized geothermal plants with Hyperlight's low cost CSP and thermal energy storage (TES). While Hyperlight's CSP collector work is maturing quickly for commercial pilot launch, an optimal TES system for solar thermal/geothermal hybridization needs to be evaluated and ultimately developed so Hyperlight can develop commercial retrofit projects at a scale of hundreds of megawatts of renewable energy power output at sites across the United States, followed by greenfield projects in a multi-GW sized market.
