This is where the CO2 neutral city starts


Sector integration

Heating and cooling accounts for half of the EU’s energy consumption and is currently 75% fossil-fuel based. To succeed with the energy transition in Europe, therefore, decarbonizing our heating and cooling supply is essential. Energy efficiency and the smart integration of renewable energy through sector coupling, is the cost-effective pathway for achieving our goals.

A new report from Aalborg University in Denmark sets the vision and concrete pathway for decarbonizing the European heating and cooling sector by 2050, based on the significant potential of district energy and energy efficiency in Europe.

Five key takeaways from the report

Utilizing energy system synergies and exploiting energy efficiency results in a reduction in primary energy of 13% compared to a ‘conventionally decarbonized’ scenario in 2050. And it reduces total energy system costs by approximately 70 bn EUR per year.

4th generation district heating operating with low temperatures could lead to primary energy savings of around 120 TWh/year and cost savings of up to 6 bn EUR/year in the HRE scenario. It will also enable the integration of low-carbon energy sources, such as waste heat and geothermal.

With the right balance between investments in end-user savings and
investments in decarbonized energy supply, an affordable decarbonization
is possible by reducing space-heating demands by 30%.

By improving the energy efficiency of district energy systems and moving from a supply to a demand-driven system with automatic controls, savings of up to 40% can be achieved. Exact pressure-, temperature- and flow control minimizes heat losses and optimizes network operation.

Setting ambitious targets, ensuring a level playing field for different solutions and securing finance, are some of the elements the policy framework should cover. Absolutely crucial is the collection of data and the making of detailed plans for how to decarbonize heating and cooling.
