About the Company

Mainspring Energy

Onsite linear generators for scalable power

Mainspring Energy designs and ships onsite linear generators that produce electricity for commercial and industrial customers, data centers, utilities, and microgrids. The kit uses a straight-line motion that is converted into electric current by magnets moving through copper coils, driven by a flameless, low-temperature air-and-fuel reaction with only two moving parts and an oil-free air-bearing. The system is fuel-flexible, handling natural gas, biogas, hydrogen, ammonia, and propane, and it scales from about 250 kW to more than 100 MW, with near-zero NOx and no after-treatment required. The company sells power as a service, enabling installations with no upfront cost and ongoing payments based on energy use, aiming to lower operating costs and increase energy resilience for its customers.
