i. Topic Area 1: Scalable Concentrating Solar Collectors This topic area solicits innovations to decrease the installed costs of solar collectors to $50/m2 with high reliability and efficiency over a 30-year lifetime. Heliostat systems, line-focusing collectors, and other novel collector forms are of interest.Areas of Interest Areas of interest include, but are not limited to: Advanced manufacturingAutomated robotic installationCommunication and control systemsStructures and facetsSolar field analysis tools and standardsAnti-soiling and cleaning technologiesWind and weather impact ii. Topic Area 2: Scalable Supercritical Carbon Dioxide (sCO2) Turbomachinery SETO solicits proposals for RD&D to enable the deployment of sCO2 turbomachinery for advanced CSP systems. Multiple heat engine and heat pump cycles are of interest to enable cost-effective CST plants coupled with thermal energy storage. iii. Topic Area 3: Scalable Concentrating Solar-thermal Receivers and Reactors This topic solicits proposals for novel solar receivers, solar reactors, and improvements to existing solar receiver concepts. Successful receiver or reactor technologies will support the deployment of CST systems that can impact the U.S. market. Targeted outcomes include: Development of a complete receiver subsystem with ≥10 MWth capacity and ≥750 ⁰C outlet temperature that can be integrated and tested with a ≥10 MWe sCO2 power cycle. Development of a ≥1 MWth reactor archetype that integrates solar thermal energy with industrial production of chemicals, cement, or minerals. Testing and integration of solar steam or heat with the product of industrial products for scaled up reactor use.Enabling near-term cost, reliability, and performance improvements of commercial CST receivers.De-risking receiver or reactor concepts to enable novel CST systems which can achieve broad commercial deployment.
