About the company:

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.

Senior Controls Engineer

Fourth Power is developing and commercializing the lowest cost energy storage technology on the market to enable the utility grid to operate 24/7/365 on renewable energy. Our batteries store heat in low-cost carbon blocks at up to 2400 degrees Celsius – half the temperature of the sun. The batteries then convert this heat back to electricity using thermophotovoltaics (TPV) on demand.

Fourth Power has a culture of teamwork, continuous innovation based on first principles, and relentlessness in tackling challenging problems. Fourth Power is looking for highly skilled, experienced, and motivated individuals who share our passion for mitigating climate change.
