Shannon Miller is the chief executive officer and co-founder of Mainspring Energy — a Menlo Park, California company that sees itself as part of the affordable, reliable, net-zero carbon grid of the future. 

She leads the design, manufacture, and commercialization of the Mainspring Linear Generator, whose fuel-agnostic design enables it to adjust dynamically for varying fuel quality and different types of fuels. Those fuels include renewables such as biogas, green ammonia, and green hydrogen — which is why many of you solar warriors will want to listen to this podcast.

This innovative generator aims to increase grid reliability and resilience while accelerating the transition to clean fuels. How does it do that? Where did the idea originate? And how did Mainspring grow from zero in 2010 to near unicorn status? 

We’ll explore all those questions in today’s conversation with Shannon, a remarkable woman who holds a bachelor’s, master’s and a Ph.D. in mechanical engineering from Stanford University and was recognized in 2012 by the MIT Technology Review as one of “35 Innovators Under 35.” And just this month, she was recognized for advancing women’s leadership in clean energy as one of only 9 annual DOE awardees for the C3E initiative.

Mainspring Energy has raised nearly a half a billion in funding, including $290 in the Series E round announced only a few weeks ago. That’s no small feat. 

A former National Science Foundation Fellow, Shannon received funding from the Global Climate Energy Project to advance her research at Stanford on improving fuel conversion efficiency to electricity. She collaborated with Mainspring Co-Founder and Chief Technology Officer Matt Svrcek to design and develop the early prototype that served as the foundation for Mainspring’s linear generator technology.

Join us to learn more about how Shannon, Matt and Chief Product Officer Adam Simpson, the company’s third co-founder, combined low cost and low emissions with high efficiency, fuel flexibility, and full dispatchability to create the Mainspring Linear Generator.
