Linear Generator Technology Designed From First Principles

A fundamentally new power generation technology designed for high efficiency, low cost, and ultimate flexibility.

The Need for 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 resiliency. Getting there requires flexible new onsite technologies that can adapt to the shifting grid landscape – including the transition from natural gas to renewable fuels like biogas and hydrogen.

The Mainspring Linear Generator delivers an unmatched level of flexibility for the transition ahead. It’s distributed so you can site where power is needed, it’s dispatchable so you can ramp up and down to complement renewables and energy storage, 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.
