To Decarbonize heating : a major challenge

2.5 billion tonnes of CO2 generated by heat production worldwide

LOW T° HEATING, AN ENERGY-INTENSIVE SECTOR WITH HIGH CO2 EMISSIONS

Heat accounts for 40% of energy consumption in Europe. Nearly 70% of this is produced by fossil fuels, in particular gas, coal and fuel oil.

And 80% of this heat is for hot water and heating at less than 100°C. As well as reducing consumption, the two major low-carbon solutions for the transition are heat pumps and heat networks.

Calogena wants to contribute to the targets for reducing greenhouse gas emissions in France, as set out in the National Low Carbon Strategy, and more widely at European level.

EUROPEAN DISTRICT HEATING NETWORK CAPACITY SHOULD MORE THAN DOUBLE BY 2050

The development of district heating networks represents a major opportunity to decarbonise heat production: Wherever urban density justifies it, the most efficient way of decarbonising low-temperature heat is through district heating networks.

Current district heating capacity in Europe is around 450 TWh out of the 3,100 TWh of the low-temperature heating market, and 60% of this production is still fossil-based.

If we are to succeed in decarbonising heat production by 2050, the share of district heating will have to increase significantly. The Heat Roadmap Europe forecasts a significant increase in this contribution, from 13% to over 45% by 2050.

NUCLEAR POWER IS INDISPENSABLE TO DECARBONIZE DISTRICT HEATING

Most non-carbon heat production solutions are linked to local opportunities. Biomass, the only source currently considered to be used on a large scale to replace fossil fuels, will rapidly reach a ceiling in terms of available resources. Nuclear power is therefore INDISPENSABLE if we are to reduce our carbon footprint by completely decarbonizing heat production.

The Calogena project proposes a solution designed to decarbonize district heating in Europe and thus make a significant contribution to the energy transition.

Each Calogena module could decarbonize district heating by 30,000 tonnes of CO2 a year if it replaces a gas-fired installation, and twice as much if it uses coal.

The main benefit of Calogena is the significant reduction in CO2 emissions when producing heat for the networks.
