On the pathway to a decarbonised energy system, renewable energy will play an increasingly important role. CHP is becoming more renewable, as RES share in CHP has doubled over the past 10 years reaching 20%. Indeed, CHP is the best way to increase the efficiency of biomass and biogas energy production to more than 70%, whereas the average efficiency of a biomass power plant can be as low as 33%.
At the same time, by providing flexibility across different energy vectors CHP can enable a higher share of intermittent renewables on the grids.
Policy should recognise the potential of CHP to improve the efficiency of bioenergy, while not ignoring the flexibility and grid cost reduction benefits of all high efficiency cogeneration.
