Smart district heating and cooling grids - demand

District heating and cooling grids cover the generation and distribution of thermal energy in district networks. Smart district heating and cooling grids aim to improve the management of energy demand. Such networks are optimised through the use of new technologies including heat meters and heat substations (heat exchangers). New energy control functions of substations include monitoring and control via the internet or digital radio. At the consumer end, in hot water and radiator systems, new devices such as variable-speed radiator pumps may be required.

These systems, supplying predominantly residential buildings and districts, are able to de-couple fluctuations in the heat demand of buildings from the network conditions – in other words, they smooth demand peaks – without perceptible changes in comfort. This allows the network’s heat demand to be stabilised, energy efficiency to be improved, and heat (or cooling) loss in the supply network to be reduced by up to 20%.

List of projects where this technology is being implemented.

STORM

The STORM project tackles energy efficiency at district level by developing an innovative district heating & cooling (DHC) network controller. Based on self-learning algorithms, the developed controller will enable to maximize the use of waste heat and renewable energy sources in DHC networks....

REPLICATE

The REPLICATE project will generate smart city business models, and tailor-made solutions in the areas of energy, transport and ICT. There will be pilot actions in energy efficiency, efficient and sustainable transport and integrated infrastructures. The key to the project’s approach is in...

OPTi

The OPTi project aspires to create a long-lasting impact by rethinking the way district heating and cooling (DHC) systems are architected and controlled. The overarching goal is to create business benefit for the industry as well as to ensure optimal end-consumer satisfaction. OPTi will deliver...

PITAGORAS

The PITAGORAS project focuses on the efficient integration of city districts with industrial parks through smart thermal grids. Technologies and concepts for low and medium temperature waste heat recovery, considering as well integration with renewable energy sources (RES), and heat (and power)...

CITyFiED

The CITyFiED project aims to develop a replicable, systemic and integrated strategy to adapt European cities and urban ecosystems into the smart city of the future, focusing on reducing the energy demand and GHG emissions and increasing the use of renewable energy sources by developing and...

Interopertional payment system Control system...

CELSIUS Site Gothenburg

In Gothenburg a large amount of waste heat, from both waste incineration and industries, is used in the district heating system. There is also heat pumps taking care of the heat in sewage and plants using bio fuels such as wood pellets, wood chips and bio oil. There is also a district cooling ...

CELSIUS Site London

To supply new heat users​ , the existing Bunhill Heat and Power Network in London will be extended to utilise existing sources of waste heat and to explore the opportunities for the system to utilise a lower operating temperature. This demonstrator will develop knowledge and expertise of how to...

CELSIUS Site Rotterdam

As part of the CELSIUS project a 160,000 m2 mixed use building integrated energy system will be demonstrated in Rotterdam. A high-temperature hot water heat distribution system supplies water to all functions needed (residential and hotel). Through a low-temperature heating system, heat is supplied...

PITAGORAS Site Brescia

The demonstration plant in Brescia includes medium/high temperature waste heat recovery (≈600ºC) from a steel foundry and ORC unit (2,1 MWe) for heat and power generation. It will be connected to the existing city district heating network. *Disclaimer: There is not sufficient information available...
