Today’s commercially operating Concentrated Solar Power (CSP) is run at temperatures used in thermal electricity production and mid temperature industrial processes; 400°C to 600°C. But policy […]

The Economics of Running CSP as a Capacity Resource in the 100% Renewable Future

A new paper to be published in the journal Energy Conversion and Management: X: Using Concentrating-Solar-Power Plants as Economic Carbon-Free Capacity Resources – develops an approach to assessing the capacity contribution from CSP plants with thermal energy storage in a future Southwestern US grid once there is a very high level of other renewables like […]

These 25 Advanced CSP & CST Technologies to Share $33 Million US DOE Funding

The Solar Energy Technologies Office Fiscal Year 2021 Photovoltaics and Concentrating Solar-Thermal Power Funding Program (SETO FY21 PV and CSP) funds research and development projects that advance PV and CSP to help eliminate carbon dioxide emissions from the energy sector. On October 12, 2021, SETO announced that 40 projects were awarded $40 million. Twenty-five of those projects will receive almost $33 million to research and develop CSP technologies that help […]

Why Likana’s 24-Hour Solar Bid under $34/MWh Lost in Chile

At the annual SolarPACES Conference (held virtually for the second year) Cerro Dominador’s CEO Fernando Gonzalez answered questions from the international network of concentrated solar power (CSP) researchers and developers attending about exactly what happened in the recent Chilean energy auctions with the record-low bid for CSP at under $34/MWh. How Cerro Dominador bid a […]
