Mainspring Linear Generators
Reliable, fuel-flexible generation that outperforms fuel cells
The future-proof way to generate onsite power
250 kW – 50 MW+ options.
High Efficiency
The Mainspring Linear Generator delivers unmatched efficiency through innovative, low-temperature, linear motion technology. No emissions controls required, and permits into all air districts out of the box. Higher efficiency drives lower total cost of ownership.
Fully Dispatchable
The product provides fully dispatchable power, allowing you to ramp up or down instantly to meet real-time energy demands. Black Start, Load Follow, and fully island capable.
Fuel Flexible
The only commercially available technology that can fuel switch in real time, under load. Designed for fuel flexibility, it runs on natural gas, biogas, hydrogen, or other clean fuels to suit your energy strategy. A Mainspring linear generator is the most future fuel ready option.
Speed to Power
With fast deployment and modular design, you can get reliable onsite power up and running in just weeks, not months. Contact us below to learn more about current lead times.

How it Works
The Mainspring Linear Generator — distinct from an engine, turbine, or fuel cell — directly converts motion along a straight line into electricity using chemical energy. At the heart of the product is the linear generator core. Mainspring Linear Generators feature two cores in each package, working in tandem.
