The 5th generation urban heating and cooling network (5G DHC) was first developed in Heerlen (Netherlands) by Mijnwater Ltd. Unlike traditional district heating, it is an intelligent thermal network based on a low-temperature local loop. Decentralized energy production, thanks to heat pumps located at the user's premises, allows energy exchange on the grid, where flows are demand-driven. This concept allows the recovery of cold and heat emitted by supermarkets, datacenters, factories, offices etc.
D2GRIDS is the acronym for "demand-driven grids". It is an Interreg North West Europe (NWE) project lasting over 3 years (2018-2022). Mijnwater Ltd. based in the Netherlands is lead partner. The project comprises 12 partners and 7 secondary partners. Five pilot sites located in Paris-Saclay (France), Bochum (Germany), Brunssum (Netherlands), Glasgow and Nottingham (United Kingdom) will develop 5G DHC networks.
The D2GRIDS project aims to develop 5th generation urban heating and cooling networks (5G DHC) in Europe. They will allow to anticipate the needs or sources of fatal heat, cold or renewable electricity in their vicinity. Similarly, local collective self-consumption logic will be optimized by broadly integrating heating and cooling needs, storage capacities or associated thermal or electrical flexibility.
The objective is to maximize the share of renewable energies in these local energy loops, through an industrialization of the approach, a standardized technological model, and a clarification of the business model to strengthen the interest of these projects for third party investors.
The project involves the implementation of 5 demonstrators in Paris-Saclay (FR), Bochum (GE), Brunssum (NL), Glasgow and Nottingham (UK). D2Grids will also prepare similar developments in Parkstad Limburg, North-East France, Flanders, the Ruhr region, Scotland and the East Midlands (United Kingdom). Dedicated education and training programmes will be set up by Open University, a partner in the project, providing expertise in post-graduate and digital learning.
As a communication partner in this project, Construction21 will implement a multi-channel communication strategy (newsletter, social networks, online communities, videos). While disseminating the project's news, Construction 21 will also provide general information on urban heating and cooling networks, thus creating a community of interest around the project. Raising awareness and increasing the knowledge of professionals about this new technology will thus contribute to its adoption. The pilot site visits will present the results of the project and begin the commercialization phase.
Several results are expected, including:
Strategic and feasibility studies to support and deploy the approach;
Training programmes for professionals and potential project owners;
The construction of a transnational community of experts via an exchange platform. This will allow feedback from projects and consolidate a catalogue of best available technologies;
An analysis of the potential approach potential of "Smart Contracting", particularly based on blockchain. It will thus serve to create greater trust between actors. It will also facilitate the implementation of local energy exchange marketplaces on these energy loops.
This €19.3 million project is financed by Interreg North West Europe funds for 60% of the total budget, €11.6 million.
