This winter several field trials have started with biomass fired Microgen Combined Heat and Power Solutions. Tests take place in all kinds of different special environments. One of these locations is high in the Japanese Alps. An off grid  Kira pellet  gasifier system powered by a MEC Free Piston Stirling engine was installed at a ski resort close to Sapporo in December 2023. Extra efficiency was obtained by cooling the Stirling cooling liquid with the abundant snow present. Besides generating power, which is about 24-28 kwh electric a day, the heat is used for space and place heating.
