The product portfolio comprises three types of energy generation: CHP plants in the output range from 20 kW to 4,500 kW for operation with hydrogen, natural gas, biogas and other lean gases, large heat pumps in the range from 100 kW to 2,6000 kW as well as peak-load gensets with an electrical output of 500 kW or more. CHP plants operate with efficiencies of 90 percent and more, while large heat pumps achieve efficiencies of 300 to 500 percent, depending on the general conditions. With its products and services, 2G is at the interface to a decentralized, secure and largely decarbonized energy supply. More than 9,000 2G systems have already been installed worldwide in various applications, supplying electrical and thermal energy to a wide range of customers from the housing industry, agriculture, commercial and industrial companies, energy suppliers, municipal utilities and local government authorities.
