Fourth Power is a thermal battery energy storage company. Our technology makes renewable energy an on-demand energy source through utility-scale thermal storage. We can harness today’s wasted wind and solar production to respond to grid needs at a cost competitive with fossil fuels.

Our modular battery can provide 5 to 10 hours of storage to meet needs now and scale with renewable deployment for needs up to 100 hours and any increment in between. With the ability to provide short- and long-duration energy storage (LDES), we can start small and grow with the grid to save consumers money and ensure a clean energy future.

I’m the CEO of Fourth Power, an MIT spin out backed by DCVC and Breakthrough Energy Ventures that brings low cost, and reliable storage to the grid to allow renewables to provide energy at all hours of the day.

My journey has taught me that climate change mitigation requires leadership from all levels of society. I’ve worked on this problem as a former federal regulator, as a leader at the world’s largest company and now as the CEO of a clean energy startup.
