CELSIUS City has established an intelligent heating system covering virtually all the households and commercial buildings in the appropriate high density areas of the city and an energy efficient district cooling system for its commercial customers. These systems make use of a range of excess heat sources all created within the city during the course of an average operational day, for example from various industrial and datacentre activities, heat extracted from sewage and bio-based heating. CELSIUS City not only consumes much less fossil fuel generated energy than a traditional European city; but it also plays a fundamental role in supporting the resilience and security of the electricity network by effectively utilising existing network capacity for connecting new distributed generation and for providing grid balancing. This becomes more relevant via thermal storage, when excess renewable electricity, generated for example by wind turbines, is being supplied into the grid.
Main results
The demonstrators constitute a package of innovative state-of-the-art energy efficient technologies, systems and practices. To cover the whole CELSIUS City concept within this demonstration project, 12 new demonstrators were built. The demonstrators already in operation will secure a full range of innovations and solutions covering the five categories necessary to display and demonstrate the CELSIUS City commitment. In the menu below, the demonstrators can be sorted under the five categories: End User, Infrastructure, Storage, Sustainable Production, and System Integration. (The demonstrators can also be sorted under each partner city)
