The downside of solar energy is that it cannot be generated at night.

But John King dreams of solar with an on-off switch. And he’s developed concentrating solar-thermal power (CSP) technology that facilitates the massive geological storage of thermal energy. Thermal energy that can be brought to the surface and used to generate power—any time of the day or night. 

John is the CEO of Hyperlight Energy, a technology developer and manufacturer based in San Diego. The company's flagship product is Hylux, a disruptively low-cost CSP system.

On this episode of Clean Power Hour, John joins Tim to discuss Hyperlight’s next-generation CSP technology and explain why he’s focused on decarbonizing oil production—while simultaneously producing renewable electricity. 

John shares his vision of repurposing the 100,000 oil wells in California using geological thermal energy  storage (GTES) and describes where in the US it makes sense to deploy Hyperlight’s CSP technology.

Listen in for John’s insight on converting combined heat and power (CHP) facilities into solar cogeneration plants and learn how we might make direct air capture a byproduct of a renewable power plant!
