Onsite linear generators convert straight-line motion into electricity using a flameless, low-temperature air–fuel reaction that drives magnets through copper coils. With only two moving parts and an oil-free air-bearing, maintenance is reduced, and the system runs on multiple fuels (natural gas, biogas, hydrogen, ammonia, or propane) with seamless switching. Modules scale from about 250 kW to over 100 MW and produce near-zero NOx without after-treatment. The energy-as-a-service model lets customers install with no upfront cost and pay for the energy used, serving commercial and industrial customers, data centers, utilities, and microgrids, with financing and deployment partners like NextEra Energy Resources and Schneider Electric; the company has attracted major investors and is expanding manufacturing to support growth.

Simplify's Take

What believers are saying

  • Utah Municipal Power Agency selected Mainspring for a 48 MW project starting in 2027.
  • Chattanooga’s biogas project validates wastewater and municipal resilience use cases.
  • The April 2025 Series F raised $258 million, bringing total financing above $800 million.[1]

What critics are saying

  • Hydrogen and ammonia deployments depend on permitting, safety, and reliable fuel supply.
  • Large public references create execution risk if availability or emissions miss expectations.
  • Capital-intensive manufacturing requires sustained bookings growth before scale economics improve.

What makes Mainspring Energy unique

  • Linear generators provide dispatchable, modular onsite power from 250 kW to 100+ MW.[1]
  • Fuel switching across gas, biogas, hydrogen, and ammonia is a core feature.[1]
  • Low emissions and no oil-based maintenance simplify siting, permitting, and operations.[1]

Chattanooga converts wastewater methane into electricity to cut $300K monthly energy costs

Chattanooga's Moccasin Bend Environmental Campus is partnering with Mainspring Energy to convert wastewater methane into electricity, aiming to cut roughly one-third of its $300,000 monthly energy costs. The project will install six linear generators this year, producing 1.5 megawatts initially, with plans to double capacity to three megawatts following campus upgrades. The system will eliminate routine methane flaring whilst strengthening grid reliability by generating power on-site. Once fully operational, it will rank amongst the largest municipal biogas-to-power projects in the Southeast. Mainspring's low-emission generators can run on biogas, natural gas, hydrogen or ammonia, allowing fuel source flexibility. The project reflects growing municipal focus on infrastructure resilience whilst reducing emissions and stabilising long-term energy costs for ratepayers.

Utah Municipal Power Agency selects Mainspring for 48MW local power generation project

Utah Municipal Power Agency has selected Mainspring Energy to supply 48 MW of dispatchable local generation capacity using linear generators. The greenfield project in central Utah is scheduled to begin operations in 2027. UMPA chose Mainspring's technology to address rising electricity demand whilst meeting sustainability and cost objectives. The linear generators offer emissions below 1.5 ppm NOx, rapid factory manufacture and installation, and qualify for a 30% investment tax credit. The modular design ensures high availability during maintenance events. Mainspring began commercial shipments of its linear generators in 2020 and has hundreds of megawatts in development. The company partners with major energy firms including AEP, NextEra Energy Resources and Schneider Electric.

Verdagy To Supply Hydrogen To Mainspring Energy For Its Linear Generators

Friday, 30 May 2025Verdagy’s Moss landing plant has been in operation for four years with more than 20,000 hours of operation with commercial cells and over 200 tons of hydrogen produced. The fully automated, 24/7 plant provides Mainspring constantly available, low-cost hydrogen as a fuel for power generation.The collaboration establishes a ready hydrogen fuel source for Mainspring’s fuel-flexible linear generators and provides Verdagy with onsite offtake for its hydrogen and electricity to support its electrolysers operation. The two companies expect to begin operations by summer 2025.“Verdagy and Mainspring Energy are demonstrating how we can improve energy resiliency for the electrical grid, datacentres and other applications” said Marty Neese, CEO of Verdagy. “This collaboration with Mainspring Energy is a compelling model for clean, flexible, on-site power solutions.”Building on its expertise in producing clean hydrogen at scale, Verdagy is now reducing operational costs by converting hydrogen into power and cycling it back into the facility.“This agreement presents an excellent opportunity for Mainspring to showcase our linear generator’s capabilities operating on hydrogen and for Verdagy to demonstrate its high resiliency industrial grade production operation” added Shannon Miller, Mainspring CEO and Founder. “We’re pleased to partner with Verdagy to highlight the significant potential of hydrogen in power generation.”By powering Mainspring’s Linear Generators with hydrogen produced on-site, the installation demonstrates how low-carbon energy can be deployed at the point of use – critical for enhancing resiliency in grid constrained and mission-critical environments. This co-located model for hydrogen consumption to generate power is crucial as grid constraints grow.For additional information:VerdagyMainspring Energy
