Technologies

Combined Heat and Power (CHP) technologies generate electricity and useful heat simultaneously, resulting in the efficient use of biomass. The main CHP technologies for agricultural and woody biomass are:

  • Biogas produced from animal waste

– Biogas is produced via anaerobic digestion and used in gas engines to drive generators for electricity generation. Excess heat from the gas engine and generator is used for other purposes such as heating greenhouses.

  • Gasification of wood chips

– Gasification of wood chips produces synthesis gas or syngas which can be burned in gas engines to drive generators for electricity generation. Heat from the gas engine and generator is used for other purposes.

  • Rankine Cycle CHP Plant

– Biomass is burned in a boiler to heat water and convert it into steam, which drives a turbine and a generator to generate electricity.

  • Organic Rankine Cycle CHP Plant

– In an Organic Rankine Cycle system instead of water another fluid is vaporized to drive the turbine.
