Qnergy produces electric power systems built around Stirling engines that operate as enclosed, frictionless external combustion systems. Its engines require no lubrication, oil changes, or repair and can deliver tens of thousands of hours of uninterrupted operation. The company's power solutions work with a broad range of heat sources, including raw natural gas and biogas. Qnergy leverages reliable off-grid power to help customers eliminate methane emissions. Use cases cited include driving air compressors to reduce methane emissions from pneumatic devices in the natural gas industry and using biogas from organic waste to provide on-site power. The company recently closed a $16 million Series C financing.
