The European Green Deal promises to deliver on a net-zero energy system by 2050, through higher ambition on energy efficiency, system integration and renewable energy. A study by Artelys finds that cogeneration is a primary enabler to achieve carbon neutrality in Europe by 2050. Realising the cost-effective potential for cogeneration in all sectors will maximise energy efficiency and integration of the European energy system at the lowest cost, while bringing key benefits to end consumers.

The Artelys study “Towards an efficient, integrated and cost-effective net-zero energy system in 2050: the role of cogeneration” was commissioned by COGEN Europe and is supported by 26 industry partners spanning across the entire energy value chain. Building on the European Commission’s ambitious 1.5 TECH scenario in the Long Term Strategy, the study optimises the uptake of cogeneration in terms of both efficiency and flexibility across integrated heat and power systems.

The study finds that there is cost-effective potential for cogeneration as a key solution in a highly electrified, highly renewable and low demand net zero emissions energy system. When considering higher shares of bioenergy sources, cogeneration uptake is even more relevant fostering the efficient use of these fuels. Optimising cogeneration as part of integrated energy systems leads to energy system cost reduction of €4.1-€8.2 billion and allows to reduce CO₂ emissions by 4-5 MtCO2 annually. Cogeneration will displace less efficient power-only and heat-only generation, contributing 13-16% of total power and 19-27% of total heat production in 2050. Optimised cogeneration will operate flexibly and efficiently when and where needed, especially at times of peak demand by heat pumps and electrical vehicles and insufficient wind and sun generation.
