H2PS-5, is a micro power generating unit. The unit is designed for dual operation, to function either as stand-alone power system delivering up to 5 kW electric power or as a Combined Heat and Power (CHP) system, delivering additionally up to 6 kW thermal energy in the form of hot water. The system is multi-fuel fed, i.e. it can operate with either Natural Gas, Propane/LPG or Biogas, converting it to electrical power through an intermediate production of hydrogen (via steam reforming) using a Proton Exchange Membrane Fuel Cell (PEM-FC)
