District heat and waste heat

Cogeneration and district heat

The integrated use of heat flows has significant potential in relation to energy efficiency and climate protection. The current provision of heat accounts for around half of the total final energy consumption in Germany.

The combined generation of electric energy and heat in cogeneration plants and grid-bound heat supply for spatio-temporal integration of heat generation and consumption are key technologies for an efficient energy system. We carry out research and provide consultancy services in relation to potentials, technologies and policy instruments.

 

Waste heat and process heat

Industry and businesses consume – and release – considerable quantities of heat. A climate-friendly heat supply relies on efficiency-increasing technologies and renewable energy carriers. We quantify potentials, link these analyses with our building model and develop policy instruments for the decarbonisation of the process heat market.
