The company turning waste methane into reliable power - and destroying the emissions while it does it.

THE MASTHEAD. Qnergy's logo and tagline, "Powering Methane Abatement." Everything the company ships is designed and manufactured in the United States, out of Ogden, Utah.
Out on a remote gas well pad, there is no power line, no crew on site, and a small stream of methane that never stops. It is invisible, it is worth little on its own, and over 20 years it warms the planet roughly 80 times more than the same mass of carbon dioxide. Qnergy's answer is almost stubbornly practical: build a generator that runs on the leak itself.
Founded in 2009 in Ogden, Utah, Qnergy is a cleantech manufacturer built around one distinctive piece of hardware - the Free Piston Stirling Engine (FPSE). It is, by the company's account, the only commercial free-piston Stirling generator on the market. The Stirling engine is not new; it was patented in 1816 and then largely set aside. Qnergy's contribution was to make it reliable, sealed, and durable enough to sit unattended in a field for years, converting low- or high-grade gaseous fuels into grid-quality electricity.
That combination - remote power plus methane destruction - is the whole pitch. Qnergy's PowerGen systems take natural gas, propane, biogas, or associated gas streams and turn them into useful energy at sites the grid never reached. And because the engine burns the methane cleanly through external combustion, it can, in the process, destroy the very emissions operators are under growing pressure to eliminate.
Waste methane or associated gas that would otherwise vent or flare is routed to the unit.
The Free Piston Stirling Engine burns the fuel externally - no cylinders, near-zero maintenance.
Heat drives the sealed piston to generate reliable, grid-quality electricity on site.
Methane is destroyed in the process, cutting a potent greenhouse gas at the source.
Carbon dioxide gets the headlines, but methane does outsized short-term damage. Cutting it is one of the fastest levers available to slow warming - and much of it leaks from exactly the remote, hard-to-reach sites Qnergy serves.
The Free Piston Stirling Engine is at the core of our methane abatement technology.- Qnergy
Stirling generators at 600, 1200, 1800 and 5650 watts. Runs on natural gas, propane, biogas and associated streams with minimal servicing and low total cost of ownership.
Compressed-air pneumatics that replace methane-venting pneumatic devices on well pads with clean compressed air.
A landfill-gas Stirling generator and enclosed flare built for small, unregulated landfills - designed for reliable, unmanned operation on landfill methane.
Captures vapor from smaller tank storage systems that would otherwise be vented to atmosphere.
Remote monitoring and control for tracking and managing deployed units across sites.
Turns verified methane abatement into voluntary carbon credits - sold to buyers such as Climate Investment.
Hundreds of oil and gas operators across upstream, midstream and downstream operations, plus landfill operators, livestock and dairy farms, and other remote or off-grid industrial sites. Units are deployed across the U.S., Canada, Latin America, Australia, India and beyond.
Methane venting from gas pneumatics, compressor leaks, vapor recovery, cathodic protection, and the plain need for power where there is no grid. Qnergy lets operators electrify and automate well pads while cutting emissions.
Diesel needs fuel deliveries; solar needs sun and storage; flares don't produce power. Qnergy's FPSE runs on the waste gas already present, generates continuous power, and destroys methane - exceeding EPA guidelines by orders of magnitude in third-party testing.
Diesel and solar remote-power systems, conventional flares and combustors, thermoelectric generators, other biogas engines, or grid tie-in where it exists. Qnergy stands out as the only commercial free-piston Stirling generator.
Powering Methane Abatement.- Qnergy company tagline
Qnergy sells and services distributed methane-abatement and remote-power hardware, supported by its monitoring dashboard. Its newer twist is recurring revenue: verified methane destruction becomes carbon credits, sold into voluntary markets. That aligns the environmental case with the financial one - operators cut emissions without giving up profitability.
The leadership bench reflects a manufacturing-first culture, drawing from Republic Services, GE Healthcare, U.S. Navy nuclear propulsion, and United Airlines - places where field reliability is the entire job.
