Celsius Initiative: Accelerating energy transition in cities

Celsius is a collaboration hub for efficient, integrated heating and cooling solutions supporting cities in their energy transition to carbon-neutral systems. Celsius gathers and shares technical, economic, social and policy expertise. Celsius connects members, exchange and foster innovation, leading to solutions that accelerate sustainable development in Europe and across the world.

Thermal Energy Systems of the Future

– hot trends and cool solutions for cities –

Combined with the FED project‘s end conference, this two-day conference will bring together politicians, industry representatives and research institutions from across Europe to connect and exchange ideas on how urban thermal energy systems are developing and how these integrated heating and cooling solutions of the future will allow smart cities to satisfy the energy needs of its citizens and businesses in a sustainable way. Including hands-on workshops for city representatives on the following topics:

  • Business models and risk analysis for infrastructure development
  • Sustainable cooling solutions
  • Facilitating the replication of demonstrators
  • Decarbonisation pathways for cities

Celsius Summit 2018: Bringing Sustainable Heat and Cold to the Heart of Our Cities

The second CELSIUS Summit was held in Brussels on  November 21, 2018 and marked the launch of the second phase of the successful European project on district heating and cooling. With a wider scope CELSIUS wants become a hub for knowledge sharing in the field of sustainable heating and cooling in Europe.

– We want cities to connect with us and then we will act as matchmakers, providing knowledge for those who need it from those who have it, says Katrina Folland, CELSIUS Project Leader from Johanneberg Science Park in Gothenburg.

A platform of networking and knowledge, CELSIUS takes a holistic approach to overcome technical, social, financial and political barriers to district heating and cooling solutions. Read more about CELSIUS or watch a film.

The goal of signing up 50 CELSIUS member cities is surpassed! The CELSIUS network now welcomes more district heating and cooling stakeholders: the CELSIUS City Supporters.

The CELSIUS Wiki is an online district heating and cooling knowledge resource that is growing as more representatives join the CELSIUS network and contribute. CELSIUS addresses policy framework issues through consultations and Position Papers.

It is with a great honour CELSIUS has received awards for the work of promoting smart district energy solutions.

The EU Clean Energy Package

In November, 2016, the European Commission proposed a package of measures to keep the European Union competitive as the clean energy transition is delivered and changes global energy markets.

The proposal has three main goals: putting energy efficiency first, achieving global leadership in renewable energies and providing a fair deal for consumers.

District Heating and Cooling

District heating is a heating system consisting of a pipe network, filled with hot water, and heat sources (from residual heat or a heating plant). The hot water is circulated by pumps, from the heating plant to the client and back again to the heating plant. A heat exchanger at the customer transfers the heat from the district heating network to the building’s own heating and hot water systems. The return water continues out through the return pipe and is pumped back to the heating plant, where it again is heated.
