Mainspring Energy

Mainspring Energy, headquartered in Menlo Park, California, was founded in 2010 by three Stanford engineers. The company offers innovative energy solutions for commercial and industrial sectors, biogas projects, mobility and EV charging, data centers, utilities and IPPs, and energy infrastructure. Their flagship product, the Mainspring Linear Generator, delivers reliable, clean power at any scale and is designed to meet customers’ capacity, resilience, and cost needs while facilitating a transition to cleaner fuels. This generator operates on multiple fuel types, including biogas, hydrogen, and ammonia, and is known for its high efficiency, low cost, and flexibility. It is local, dispatchable, and fuel-flexible, making it suitable for various applications and extreme conditions, such as hurricanes and extreme temperatures. The technology features near-zero NOx emissions due to its low-temperature reaction without a flame and is fully dispatchable, offering load tracking, fast on/off capabilities, black start, and islanding. With only two moving parts and no oil, the generator ensures low capital and maintenance costs. Mainspring Energy provides both direct capital purchase and financed solutions, including Energy Services Agreements and Power Purchase Agreements, and has partnered with NextEra Energy Resources for financed turn-key projects. The company has received investment from notable entities such as Khosla Ventures, Bill Gates, and American Electric Power. Mainspring Energy supports the transition to a net-zero carbon grid by increasing the use of solar and wind power and offers resources like case studies and technical briefs to showcase their capabilities. The company has a diverse team and fosters a culture of collaboration and innovation, and it also emphasizes cybersecurity awareness and warns against recruiting scams.
