We turn residual gases into electricity with unparalleled efficiency

Swedish Stirling

Swedish Stirling AB is a Swedish cleantech company that develops solutions for energy recovery and sustainable local electricity production. The company’s product – PWR BLOK 400-F – utilizes the Stirling technology’s unique ability to convert heat energy into electricity.



PWR BLOK 400-F is a container-based solution in which Swedish Stirling’s Stirling engines are used to harness energy from flare and industrial residual gas combustion.

This allows for significant electricity and cost savings to industries, as well as reducing the global carbone dioxide emissions. The PWR BLOK 400-F 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 400-F is about five years. 

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