Swedish Stirling

Swedish Stirling AB is a Swedish clean-tech company that develops solutions for energy recovery and sustainable local electricity production. The company’s product – PWR BLOK – utilizes the Stirling technology’s unique ability to convert heat energy into electricity.



PWR BLOK is a container-based solution in which Swedish Stirling’s Stirling engines are used to harness energy from industrial residual gas combustion or waste heat.

This allows for significant electricity and cost savings to industries, as well as reducing the global carbone dioxide emissions. The PWR BLOK contains 14 Stirling engines and delivers a net output of 400 kW. The container is placed next to facilities where combustion of residual gases occurs and converts the energy in the gas to electricity. At the price Swedish Stirling can offer, a customer’s payback period for the PWR BLOK  is about five to seven years. 

The company estimates the technology’s service life at up to 25 years , allowing customers to reduce the volume of electricity purchased from the grid by up to 15 percent.
