The methane, and the engine that eats it
Qnergy is a hardware company in Ogden, Utah, with 85 employees, roughly $8.6M in annual revenue, and a product that looks, from the outside, like an unremarkable green metal box. Inside the box is a free-piston Stirling engine - a design first patented by a Scottish minister in 1816 - retrofitted to eat whatever methane an operator would otherwise flare, vent, or leak.
Ory Zik runs the company. He is a physicist by training, and he talks like one. Methane, he will tell you, is roughly 80 times worse for the climate than carbon dioxide over a twenty-year window. It is also, conveniently, fuel. If you can burn it cleanly and turn the heat into electricity, you have solved two problems at once: an emissions problem and a stranded-power problem. That is the sentence Qnergy sells.
The customers are the places methane tends to accumulate awkwardly - oil and gas well sites too remote to connect to the grid, landfills where the gas seeps out of decomposing trash, dairy and hog farms where manure lagoons produce a steady drift of the stuff. Qnergy's generators run unattended, on whatever fuel is available, for long stretches without a service call. The pitch to the operator is uptime. The pitch to the atmosphere is the difference between combustion products and raw CH4.
Live cells, solar dishes, environmental math, methane
Zik's career reads oddly if you insist on a straight line. He has founded four companies, in four different technical domains, on two continents. He has also, at various points, run a science museum and helped launch the Israeli branch of Greenpeace. He does not have the standard cleantech-founder résumé; he has whatever the opposite of that is.
The through-line, if you squint, is a fondness for problems where a physical constraint gets in the way of something useful and where the fix is instrumentation. Quantomix, his first company, figured out how to put a living cell inside an electron microscope - normally a vacuum chamber, normally hostile to anything wet or alive - so that biologists could actually watch things happen. That is a physics problem that ends in a biology tool. Heliofocus, his second, concentrated sunlight to preheat the working fluid of conventional power plants. That is a thermodynamics problem that ends in a fossil retrofit. Energy Points was an analytics engine that put a common unit on the energy, water, and carbon impact of business decisions. It was acquired by Lux Research. That is a measurement problem that ends in a corporate dashboard.
Qnergy is the same instinct applied to methane. The Stirling engine has been sitting on a shelf for two centuries because it lost the market to internal combustion in the 19th century. It is efficient, quiet, and, critically, indifferent to what you burn beneath the hot end. That indifference is what makes it good at the specific class of problem Qnergy sells into. A gas well site's fuel is dirty, variable, and inconvenient. An internal combustion engine complains. A Stirling engine does not.
Founder Résumé - Domains Covered
A career, arranged chronologically

- Early careerFounds the Israeli branch of Greenpeace. His first exposure to organizing an institution rather than an experiment.
- circa 2000sFounding CEO of Quantomix - first company in the world to visualize live cells inside an electron microscope.
- circa 2007Co-founder and CEO of Heliofocus, developing concentrated solar solutions for conventional power plants.
- circa 2012Founding CEO of Energy Points, an analytical engine for environmental performance. Later acquired by Lux Research.
- 2015 - presentCEO of Qnergy, headquartered in Ogden, Utah - free-piston Stirling generators for methane abatement, remote power, and vapor recovery.
- Nov 2021Qnergy closes $16M Series C, bringing total raised to approximately $46M.
What the machine actually does
A Stirling engine works by shuttling a fixed volume of gas between a hot and a cold zone. The gas expands, contracts, and drives a piston. In Qnergy's free-piston variant, the piston does not touch a mechanical linkage; it moves on gas bearings inside a sealed head. There are, in the parts count, remarkably few things that can wear out. That is the entire commercial insight. A remote generator that requires an oil change every 500 hours is a generator that will not be at a remote site for long. A generator that will run for years without a human visit changes the economics of every use case Qnergy is chasing.
Zik's technologists have wrapped that engine in the boring, necessary hardware - flare stacks, gas conditioning, controls, telemetry - that turns a thermodynamic curiosity into a fielded product. Operators can watch the units from a phone. The units talk back. The methane that would have been a rounding error on an emissions inventory becomes a kilowatt-hour on a meter.
Qnergy has extended the same platform into adjacent uses. Vapor recovery at storage tanks. Continuous compressed air for pneumatic controllers that would otherwise vent methane into the sky with every stroke. Livestock methane at dairy and hog operations, where a manure lagoon is now, in the right hands, a small power plant. Landfill gas, which lands in the sweet spot of the technology because its composition varies constantly and the Stirling engine does not particularly mind.
Things worth knowing
Physics first
Ph.D. from the Weizmann Institute of Science, one of the most selective research programs in Israel. Undergraduate work in physics and mathematics at Tel Aviv University.
Museum director
Ran the scientific program of Israel's National Museum of Science before founding his first company. An unusual footnote for a hardware CEO.
Greenpeace Israel
Helped establish the country's Greenpeace branch. He arrived at oil and gas customers by way of environmental organizing, not the other way around.
Patents
Holds multiple worldwide patents across his companies. Quantomix's live-cell electron microscopy work in particular is heavily cited.
Ogden, not Silicon
Qnergy sits in northern Utah, close to the oil and gas producers and dairy operators it sells to. Manufacturing, not marketing, is the point.
Anything that burns
Stirling engines are indifferent to fuel quality. Qnergy's units run on landfill gas, wellhead gas, manure biogas, propane, and natural gas alike.
Interviews and appearances
Zik does long-form better than clips. Two conversations worth an hour of your time:
