Solutions
Our products meet customer energy needs across a wide range of uses on both sides of the meter.
“We haven’t had a single month when they’ve missed a single spec. They’ve delivered on every technical dimension we care about.”
"This clean-fleet charging site is the first and largest of its kind in the world. Hydrogen-ready today, it offers a new model for substantially reducing emissions. It establishes a new, rapid, and resilient way forward and a model for clean charging of electric vehicles anywhere.”
“Mainspring’s flexible platform has potential use in a variety of applications from customer resiliency projects to grid-scale power plants.”
"The linear generator is an important component of our sustainable wastewater management practices. The addition of the Mainspring product to our plant will help us meet our clean energy goals, reduce greenhouse gas emissions, and create operational efficiencies.”
“Mainspring’s linear generator technology has allowed our business to manage electricity expenses better and lower its carbon footprint. We have already begun adopting this technology at other locations to expand this program.”
“This is a low-emissions, resilient, and affordable alternative that holds a lot of promise for our future.”
"Mainspring's technology helps to support our move to net zero carbon energy. Mainspring generators improve energy independence and buffer our growing use of solar power, while offering the potential future use of zero carbon fuels like green hydrogen and others."
"Mainspring's radical flexibility in clean power generation — the ability to operate multiple fuel types, to turn on and off rapidly, to be placed anywhere, easily and affordably — has the potential to demonstrably speed the world's move to zero-carbon electricity."
"Many commercial and industrial customers as well as utilities want clean, reliable power generation, with the capability to switch to 100% renewable fuels like biogas and hydrogen as they become available. Mainspring is able to integrate clean onsite generation with both renewables and the grid and we're pleased to support bringing this innovative product to market."
"One of the greatest challenges in the global race towards decarbonization is getting there at sustainable levels of resilience and cost. Mainspring's approach brings together these benefits in a way that no other technology we've seen can accomplish."

Linear Generator technology designed from first principles
Innovative power generation technology designed for high efficiency, low cost, and ultimate flexibility.
Our vision: Flexibility on the path to net-zero carbon
At Mainspring we believe the fastest path to the net-zero carbon grid is vastly increasing the amount of solar and wind power while building a supporting clean energy system that ensures affordability and multi-day, cross-season resilience. Getting there requires flexible, scalable, local technologies that can adapt to the shifting grid landscape – including the transition from natural gas to renewable fuels like biogas, green ammonia, and green hydrogen.
The Mainspring Linear Generator delivers an unmatched level of flexibility for the transition ahead. It’s local so you can site where power is needed, it’s dispatchable so you can ramp up and down to complement renewables, and it’s fuel-flexible so you can operate on the cleanest fuels available today and in the future. Our products are already at work at Fortune 500 customer sites, accelerating the arrival of the net-zero carbon grid.
Working at Mainspring
Mainspring is solving essential problems every day with a diverse, talented team of individuals who share our vision to address the growing threat of climate change and the need for affordable electricity for all.
