Qnergy

The company's core technology is the Free-Piston Stirling Engine (FPSE), an external combustion engine that converts heat from various sources into electricity. This engine is designed for long-life performance with no lubrication or maintenance, and some units have operated continuously for over 60,000 hours. The technology's reliability has been recognized by NASA, which has run a similar engine for over 110,000 hours. Qnergy's CEO, Ory Zik, is a physicist and serial entrepreneur with a background in cleantech, having previously founded companies in solar thermal energy and environmental analytics. His journey from environmental activist to leading Qnergy reflects his mission to apply physics to solve real-world environmental problems, specifically methane emissions.

Qnergy's business model includes selling power generators, engines, licensing, and engineering services. More recently, the company introduced a lease-to-own program to provide customers with financial flexibility. The company serves several markets, with a primary focus on the oil and gas industry, landfills, and agriculture—the three main sectors for methane emissions. For the oil and gas sector, Qnergy provides autonomous power and compressed air for onshore and offshore operations, helping to reduce methane emissions from pneumatic devices and electrify well pads. For landfills, the TORCH4 system offers a mobile, autonomous solution to destroy over 99% of methane emissions, even at low concentrations. This also creates a revenue stream for landfill owners through the generation of carbon credits. Their product line includes the PowerGen series of generators, which are available in various power levels from 600 to 5650 watts and can run on natural gas, propane, and biogas. The company also offers Compressed Air Pneumatics (CAP) systems that replace methane emissions at well sites.
