MTT developed its patented micro turbine technology in the period 2006 - 2009. This technology was initially used in the EnerTwin micro CHP system, a small power plant for domestic and SME applications. Because of its very high efficiency the EnerTwin can be classified as clean tech product. However, if operated on Green gas, Biomethane or a gas mixture containing up to 23% percentage of Hydrogen, the EnerTwin becomes an important product for the energy transition. The EnerTwin is commercially available within Europe since mid-2018.
