Introducing PG 1201!

Today at the ARPA-E Summit in Denver, Qnergy rolled out PG 1201. A low-maintenance smaller footprint Power Generator for the 1.2kW range. We have tested the system for six months and will start beta testing this month – stay tuned. One of the applications is reducing methane emission through bleeding pneumatic devices by using electric actuators. We thank ARPA-E for the support

Compressed Air Pneumatics Demonstrated in Calgary

At the Petroleum show in Calgary, our Canadian distributor OilPro demonstrated CAP3. CAP3 (Compressed Air Pneumatics) replaces methane emission from pneumatic devices with compressed air. The annual U.S. emission reduction potential of CAP3 is about 40 million tons of CO2- equivalent (equivalent to taking 9.5 million cars off the road). Wholehearted thank you for everyone involved!

Welcome To the Dungeon!

The Qnergy Applications Engineering Team has created a state-of-the-art test lab that allows the validation of any electronic piece of equipment the scientific mind can think of. This lab is affectionately referred to as “The Dungeon”. In The Dungeon, the Qnergy Team has validated the operation of its PowerGen Stirling engine remote power system on some of the most challenging pieces of electronic equipment used on remote, Oil and Gas industry installations. The most recent success story coming out of The Dungeon is Qnergy has confirmed that the PowerGen effectively and efficiently provides reliable power to many different air compressors for use on Oil and Gas sites that are required to reduce methane emissions. With the government mandates on methane emissions becoming more and more stringent, the Qnergy PowerGen will be ready to provide critical power for the operation of these sites while helping to make our air a little cleaner!

A Stirling Engine celebrates 20,000 hours of uninterrupted operation on Earth Day


A Qnergy Stirling-Based Power Generator reached 20,000 hours (more than two continuous years) of uninterrupted, maintenance-free operation. About five times longer than conventional generators.

The generator is installed in the IJ & Jeanné Wagner Jewish Community Center in Salt Lake City, Utah (JCC). It uses Qnergy’s proprietary Free-Piston Stirling technology. The same fundamental technology that was recently recognized by NASA as the “the longest running heat engine ever built” (

“It is symbolic that our generator reached the 20,000 hour mark exactly on Earth Day.” said Ory Zik, Qnergy’s CEO. “It reflects our commitment to help customers mitigate their GHG emissions in addition to reducing operating costs.” He added. “We have built hundreds of additional units that have the same design principles and thus superior reliability”.

“The generator has been providing both power and heat to our facility for more than two years” said Andrea Alcabes, Executive Director at JCC. “We are proud to be among the first users of the system and the first to reach the 20,000 hours mark” she added.



Utah-based Qnergy provides reliable remote power in the 1-10 kilowatt range. The company helps Oil & Gas companies improve operational efficiency, decrease cost and reduce emissions. Qnergy’s Stirling engine technology can use any heat source. The typical fuels are natural gas, propane and biogas. The Stirling design is an enclosed system which requires no lubrication, maintenance or repair leading to tens of thousands of hours of uninterrupted operation. Qnergy’s success is rooted in coupling innovative mechanical design with advances in software and Power Electronics.

Reliable Remote Power and Corrosion Control

Isaac Garaway (Qnergy’s CTO) pictured two Qnergy units thirty feet apart at the largest Corrosion trade show. It demonstrates the growing importance of reliable remote power to this industry.

The U.S. has about 350,000 miles of natural gas pipelines. About half are more than fifty years old. Many of the pipes are corroded and leak methane. The proven solution is cathodic protection. A critical component is reliable remote power. Thank-you Farwest and IRT for your support at Corrosion 2019. Together we go much further!


Qnergy PowerGen Trial Gen4 Application

Shell Canada demonstrates Qnergy’s double bottom line!

PowerGen outperforms the sector on both economic and climate benefits.


Qnergy trial was installed at a Shell wellpad site in Groundbirch, British Columbia in January 2019.  The Shell Engineering Group that conducted the testing receives the Low Carbon Award for installing a PowerGen!


Among Shell’s findings:

  • The PowerGen unit operated perfectly, supplying 1000W of mission-critical power and 150 meters of a hot glycol heat trace.
  • Qnergy’s Stirling engine provided an impressive 30% thermal-to-electric efficiency while maintaining a 0 VOC (Volatile Organic Compounds) emissions.
  • Qnergy SmartView IoT system allows Shell to track operation and performance 24×7 from any location. It fits into the digitization transformation.
  • The trial has shown that the PowerGen reduces GHG emissions, relative to Thermo Electric Generators and Fuel Cells, while offering a significantly lower Total Installed Cost.
  • The PowerGen has operated successfully at ambient temperatures down to -40°C throughout this trial.

Qnergy is grateful for the opportunity and remains committed to continue to supply reliable power to help our customers mitigate emissions and streamline their operations.
