ABOUT US.

Driven by a vision of the affordable, reliable, net-zero carbon grid of the future

Mainspring was founded in 2010 by three Stanford engineers seeking a new approach to generating clean, resilient, affordable electricity. Their research into high-efficiency methods of converting fuel to electricity led to the founding of the company and the development and prototype of their first linear generator. They also built a culture of collaboration and innovation.

Today Mainspring brings together a diverse, talented team of individuals who share the vision to address the growing threat of climate change and the need for affordable electricity for all. Our executive team brings deep expertise from leading clean energy companies and is backed by top-tier venture, strategic, and financial investors.

Any Fuel, Any Scale, Anytime, Anywhere

The Mainspring Linear Generator delivers unmatched flexibility for the grid transition, including the ability to switch between fuels like hydrogen, ammonia, and biogas with software, and quickly track and firm renewables with its full dispatchability. Whether deployed as a single unit or as a grid-scale array, the technology is easy to permit and interconnect in any jurisdiction, allowing for broad impact across a wide range of use cases on both sides of the meter.
