Smart Heating and Cooling in the EU
May 2016
Goal reached: 50+ CELSIUS cities
A year ahead of schedule, the partner cities of Gothenburg, London, Rotterdam, Genoa and Cologne have recruited more than 50 European cities as CELSIUS members. Krakow became the 50th to step on board. 

In their recently published Heating and Cooling Strategy, the European Commission highlighted district heating’s strategic importance for achieving the EU’s climate targets. The Mayor of the lead city Gothenburg is proud that the city’s district heating network, dating back to the 1950s, is now a European leader.
“That 50 European cities have joined CELSIUS is a confirmation that we, together with the people of Gothenburg, have chosen the right path towards creating a sustainable city. We have accumulated knowledge and expertise over the years that we can now share with other cities, so that they in turn can reduce their carbon emissions,” says Ann-Sofie Hermansson, Mayor and Chair of the Gothenburg City Executive Board. 
Each of the now 53 member cities participating in CELSIUS face different conditions for working with district heating and cooling. In some cities the district heating network is widespread and in others it is still on the starting block.
One of the cities that have joined the project is Lille in France. They see it as a golden opportunity to quickly gain access to new knowledge for developing and increasing the energy efficiency of their heating and cooling systems.

“We aim to double our district heating network by 2030. We plan to create a district heating network from the waste incineration plant, which is about 20km away, to the substations. This network could supply new users and eliminate the use of coal and gas as energy sources,” says Alain Bézirard, energy advisor in the city of Lille.
CELSIUS sent out a press release, read it here.

Good advice when starting from scratch

Words of wisdom for cities seeing the road to a mature DH/DC system as very long, spoken by Jouni Kivirinne, Manager of Business & Development at Finnish energy company Helen Oy.

He was one of the speakers at the CELSIUS workshop "District Heating and Cooling – Future challenges and showcases of good solutions" in Gothenburg on April 6.

”This is just the beginning
of something greater”

VIDEO CLIP: Intense efforts are being made to ensure that CELSIUS, now with more than 50 European cities engaged, continues to inspire and motivate progress after project closure. Leading figures in the project are now mapping out the course to making it happen. See them interviewed here.
London subway getting warmer:
A growing concern turned into an asset
There is a growing problem in the London Underground network. Temperatures in the tunnels are continuously rising, creating discomfort for passengers and a future safety concern. Soon a CELSIUS demonstrator will show a pioneering solution to this problem and another dilemma that is almost opposite but just as urgent.
”We are making a problem useful”, says Lucy Padfield, Energy Services Manager at Islington Council.

Trains running and braking are releasing heat, which is transferred to the clay surrounding the subway tunnels perforating the ground underneath London. As trains run faster and more frequenty and the ability of the soil to absorb heat is exhausted, summer temperatures are rising and creating newsletter headlines like “Is Your Tube Commute Too Hot to Handle?” and “Cooking on the Central Line”.
In Islington, the construction has begun of a CELSIUS demonstrator that will turn this problem into an asset.
“The air from a Northern Line ventilation shaft will pass across our new heat exchanger, where the unwanted heat from the Tube will be removed to find a very valuable new use: heating our council homes. It will provide our residents with cheaper, greener heat and help eradicate fuel poverty in the borough”, says Lucy Padfield.
As in many other parts of the UK fuel poverty is a cruel reality in Islington, as was covered in an earlier article in the March Newsletter, since utility prices are increasing to a level where  vulnerable residents struggle to afford to heat their homes. The project – the first of its kind in Europe – is a partnership between Islington Council, the Greater London Authority and Transport for London.
Many other benefits may also follow. The project is also looking to supply the Underground with cooler air in the summer months, by reversing the airflow across the heat exchanger. The demonstrator is predicted to make CO2 emissions drop by more than 500 tonnes each year.
The solution will also prepare the ground for a multitude of other possibilities, according to Lucy Padfield.

“It will create a real example of using a low temperature heat source for district heating development. London and other cities have many low temperature heat sources, from rivers and canals to data centres and supermarkets, and this project will show how these energy resources can provide successful ways to supply the city residents with cheaper, greener heat.”
Ship solution gaining ground
The CELSIUS demonstrator connecting a ferry to district heating in the harbour of Gothenburg is gaining recognition. A feasibility study is now underway, paving the way for a second vessel to be connected. 

The initiative comes from the transport company Stena Line who are pleased with the results of the demonstrator and the environmental benefits of not burning ship fuel when in port.
- This is great proof that the connection has been very well received and works well. Less noise, less emissions and more district heating is always a good thing, says Jonas Cognell, CELSIUS project manager.
Another positive development is that the Danish energy company HOFOR has expressed interest in replicating the solution in Copenhagen. Jonas Cognell has lectured about the demonstrator at international conferences for ports, and many of them have been curious and posed a lot of questions.
- They find it an innovative and interesting solution, but not that many cities have a district heating network as close to the port as Gothenburg and Copenhagen, unfortunately.
Great start for the CELSIUS toolbox
The CELSIUS toolbox has officially been inaugurated and opened up to our member cities. The launch webinar on March 22 attracted around 40 attendees, among them policy officer Szilvia Bozoki from the European Commission. 

The recorded launch webinar can be watched here. In the wiki you can find other webinars and presentations sharing valuable knowledge and hands-on advice gathered in the CELSIUS project.
Straight after the launch, more than 100 new wiki user accounts were created.
”It was great to see that so many of our CELSIUS members immediately visited the toolbox. Now it is important that we continue improving it together with our new cities”, says Jonas Cognell, project manager of CELSIUS.

To increase energy efficiency in the EU, CELSIUS helps cities across Europe to develop secure, affordable and low carbon district heating and cooling solutions that form part of the city's wider energy system. The focus is on maximising the use of waste heat or secondary heat within a city by capturing and using it in the heating system.

This project has received funding from the European Union’s Seventh Framework Programme for research, technological development and demonstration under grant agreement no 314441.
