A longer life for CELSIUS

The CELSIUS project has been extended to last until 31 December 2017. Several benefits follow: more elaborate results, a larger number of replicable solutions and more time to support member cities.

“The Commission has approved that the project continues nine months longer than first planned, in order to present an overall better result”, says CELSIUS project coordinator Katrina Folland. “It is natural that the energy market and surrounding world changes in a 4-year-period. We need to modify the project accordingly, in order to deliver up-to-date and relevant results.”
In order to keep the technologies and services developed up to speed, changes have been made in some of the demonstrators. Thus it takes more time than estimated to get them running, monitor the outcome, evaluate results and package them as replicable solutions. “We want to achieve all the objectives set for the project. It is very important to perform this in the best way possible, in order to make replication happen.”
The longer project period brings benefits in several areas, according to Katrina Folland. “A longer monitoring period for the demonstrators means more reliable results. The extension also gives us the opportunity to support CELSIUS cities for a longer period of time, through workshops and webinars on important topics and further development of the wiki."

European Green Capital has big plans for DH

Ljubljana is the environmental capital of Europe this year and a member of CELSIUS. The city’s heat supplier has big plans for district heating, but it will take some convincing that long-term energy efficiency has to outdo cheap solutions.
The European Green Capital is appointed each year by the European Commission in order to reward cities that work improve the urban environment and move towards healthier and more sustainable living areas.

Ljubljana, the capital of Slovenia, was appointed because of its significant transformation in sustainability over the previous 15 years. Among the measures taken are green local transport, pedestrianizing of the city centre, preserving and protecting green areas, treatment of waste and waste water and many other things. 
Hoping for many new ideas
Around 45 percent of the city apartment buildings are supplied with district heating today. The local heating and gas supplier Energetika Ljubljana is very content to be part of CELSIUS. “We find this project exactly what we have been looking for in the district heating field, on our path to take a new position within the municipal, regional and central Slovene energy markets. We hope to gain many ideas on how to improve our district heating system and business”, says Herman Janež, corporate strategy director at Energetika Ljubljana.

The focus on district energy is clear: the company wants to extend the DH network as far as technically possible. The biggest project underway is replacing two coal CHP units with gas CHP units.

Other projects are smaller scale, but still important: limiting leakages in the system and integrating renewable energy sources and waste heat into the district heating system.

As always, there are challenges on the way.
“Persuading decision makers that we shall build a new gas CHP plant, raising awareness of that energy efficiency measures and environmental protection incur costs, and that selecting the allegedly cheapest technology must not always be the main goal”, says Herman Janež.
In your opinion, what makes district heating/cooling a good solution for the future?
“From the end-user perspective, it provides more comfort than other solutions. From the environmental perspective, a large infrastructure system is more energy efficient regarding the use of primary fuel and provides more environmental and air pollution protection. The system is also easier to upgrade to new technologies. And from the financial perspective, large installations are relatively cheaper than small ones.”

Genoa demonstrator close to launch
A key component which has been missing is finally in place and the demonstrator has been completed.

The Genoa demonstrator, Expansion turbine for mechanical energy recovery, aims to increase the energy efficiency associated to industrial gas distribution in the city. It is now expected to start running at the end of September.

The late delivery of a main component, an expansion turbine by which mechanical energy is recovered in the system, has caused delays. It finally arrived in Genoa in the first week of august. The installation took two weeks and tests are needed before launching the demonstrator.

The facility is part of the development of a local energy system connected to an industrial park. It will allow shifting from the current use of low efficiency independent heating systems, which are still widespread in the city of Genoa, to higher efficiency heating solutions.

Webinar on putting pipes in the ground
Before you start digging - learn from other cities

On September 21st, CELSIUS gives a webinar for member cities titled ”Putting pipes in the ground”. One of the three speakers is Anders Fransson, development engineer at Göteborg Energi.

Why is it important for cities to look at the experience of other cities when it comes to putting the district energy pipes in the ground?
”Göteborg Energi has experience of building district heating since the early 1950’s. We have optimised our grid from one of the worst in Sweden to one of the best. We listen to what others do and we do our own research.”
What will you talk about?
”I will try to make a wide scope and talk about our history and our future, which is our common future. I will also talk about what is important to think of before, during and after construction: hopefully things that not everybody thinks of. I will try to say something interesting to both new energy companies and the more experienced ones.”
What is the most important lesson you want listeners to remember?
”That any energy company that doesn’t plan many years ahead will get disappointed.”

CELSIUS exposed to international experts

In Cologne i July, CELSIUS presented information about project demonstrators and spread the project vision and objectives to a distinguished, international audience.

The 5th International Energy and Sustainability Conference discussed pathways and technologies required in order to reach the UN goals set in Paris, of limiting global warming and decarbonizing the energy system.
This year’s focus was the necessity of integrating formerly non-integrated systems in order to end up with reliable and economically feasible systems based on renewable sources. One part was the integration of the electricity sector, heating and cooling sector, transport sector, and also water supply and sewage sector. CELSIUS made a fitting contribution since representative Aldo Perez presented the Cologne demonstrator Heat recovery from sewage water.
The event was arranged in partnership with IEEE, the world's largest technical professional organization dedicated to advancing technology for the benefit of humanity. It was attended by academic scholars from across the globe, sharing their latest research and achievements in renewable energy and sustainability, as well as a wide network of professionals.

Upcoming conferences 

... Where CELSIUS participates:

11-12 oktober, Brussels 

Euroheat & Power District Energy Days

The Commission Vice President has described 2016 as ‘the year of delivery’ for the Energy Union. Meeting its objectives will require a major contribution from district energy. The Euroheat & Power autumn conference will provide a high level forum for policy makers, industry and civil society to exchange views on how thermal networks can help deliver a smoother energy transition at a European, national and local level. 


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.
