The US Department of Energy (DOE) announced that it will invest $33 million in nine projects in seven states to advance concentrating solar-thermal (CST) systems, which would promote solar fuel production and long-duration energy storage.
CST technologies use mirrors to reflect and concentrate sunlight onto a receiver, helping to produce carbon-free clean fuels, heat, and storage for a wide variety of applications.

U.S. Secretary of Energy Jennifer M. Granholm, “Under the Biden-Harris Administration, DOE continues to invest in the next-generation solar technologies we need to tackle the climate crisis and ensure American scientific innovation remains the envy of the world.”
He added, “With today’s announcement, DOE is supporting projects that will harness the sun’s energy to power NASA space missions, beer and wine production, and everything in between.”
Advancing clean energy technologies like CST is a key part of President Biden’s comprehensive government approach to reducing harmful carbon emissions and is crucial to reaching the nation’s ambitious clean energy and climate objectives.

Three selected projects will leverage solar energy to produce renewable fuels more cost-effectively than with electricity. These projects include:
- Exergy Labs: Developing a modular dish reactor for clean hydrogen production.
- National Renewable Energy Laboratory: Designing a 1-megawatt pilot plant for producing high-value products like jet fuel.
- West Virginia University: Demonstrating direct solar-thermal integration with hydrogen production for various applications.
Six additional projects will advance thermal energy storage technologies, which can provide heat continuously or on demand. These technologies can be paired with turbines to produce electricity or serve industrial processes requiring heat.
