A prototype reflector of 20 feet by 50 feet was tested to 10,000 cycles representing a 30-year lifetime, and results of the testing showed minimal degradation. The project site preparation work was completed and the pilot system has been operating as designed. Total system annual solar-to-thermal efficiency of 1/2 acre module plant was in the range of 60% to 85%. Important milestone achieved in this project include the mass manufacture and installation of the tube structural components required to achieve cost-savings. This project was completed in March, 2019. Hyperlight energy will design and install this technology, at Saputo Cheese plant in Tulare to convert solar energy into supplemental heat for thermal processes required to process milk into cheese. In addition, this technology has a good chance of utilization to boost output of geothermal plants.View Final Report
This project has developed a low cost Concentrated Solar Power (CSP) collector to advance the market readiness of this technology. Hyperlight's CSP collector is based on the linear Fresnel reflector (LFR) and is able to make cost reductions through breakthroughs in materials, design, manufacturing, and installation. A major innovation of the system involves use of mirrors attached to UV stabilized and low-cost plastic tubes that are mounted on a sealed water bed foundation. The project has developed: (1) a single 1,000 square foot module used for lifecycle testing and validation of upgraded design elements; (2) a one-half acre system for pilot testing and demonstration; and (3) a front end engineering design study to establish the feasibility and requirements to scale the system up to ten acres and to co-locate with other renewable energy such as a geothermal facility. EPIC funds are being used as cost share funding to Hyperlight's $1.5 million grant from the US DOE.
This project will develop solar collectors that are roughly half the cost of current collectors, reducing overall system costs for concentrated solar to $99/m2 compared to existing cost of $200/m2. The LCOE from this technology i
This project will generate 3,500 mmbtu of heat per year, resulting in 50 tons of CO2 offset annually.
