HeatNet NWE: Transition strategies for delivering low carbon district heat

Project Summary

HeatNet NWE will address the challenge of reducing CO2 emissions in North West Europe by creating an integrated transnational NWE approach to the supply of renewable and low carbon heat (incl. waste heat) to residential and commercial buildings. District Heating and Cooling facilitates energy efficiency, less CO2 emissions and a greener economy. 

The project aims to develop and test 6 local district heating and cooling networks (DHC) in UK, Ireland, Belgium, France, and the Netherlands.


The overall objective is to introduce and demonstrate the 4th generation DHC (4DHC) in NWE. This is a low-temperature distribution system that minimises heat loss, integrates energy storage and renewable energy sources, and supplies multiple low energy buildings.

The concept requires the development of new institutional and organizational frameworks.

The project will result in 15,000 t CO2e saved per annum at its end.

The main outputs are:

1. A transferrable HeatNet model for the implementation of 4DHC schemes in NWE;

2. Six living labs develop, test and demonstrate through investments the HeatNet model to make it robust;

3. Transition Roadmaps plan for roll out of new technical, institutional & organizational arrangements in 6 living labs (new roles and responsibilities of stakeholders, regulation & policies, spatial planning, business models & viability, connection to finance and markets, acceptance, etc);

4. Promotion and fostering of the HeatNet model in NWE  through Transition Roadmaps to secure wide and long term impact of HeatNet. The consortium combines emerging NWE-knowhow on 4DHC (Mijnwater BV, academic, energy planning) with the capacity in the long term to reduce institutional & organizational barriers and to deliver permanent infrastructure at local and regional level. Multiple partners expertise is diverse and needed to jointly develop and promote the HeatNet-model and assist 6 successful living labs at the investment sites.

A spatial energy strategy for South West Flanders in 100 climate actions

Posted on

By signing the Covenant of Mayors, the 13 mayors of South West Flanders already signed for 40% less CO2 by 2030, and on behalf of the same 13 municipalities, regional developer Leiedal organised seven capacity-building workshops on renewable energy and durable heat earlier this year. In these workshops, within the European HeatNet NWE project framework, concrete actions were formulated to meet the climate goals set for South West Flanders. Read More

Remunicipalisation: yes you can!

Posted on

Inspired by remunicipalisation initiatives all over Europe, an increasing number of local authorities are expanding their role, not just by acting as planners but by operating their own companies and driving the local energy transition. Why is this trend happening? And how can a city set up its own company to supply electricity, gas, heating and cooling? The EU funded projects HeatNet NWE and mPower organised a workshop in Ettlingen (Germany) to answer these questions. Indeed local energy companies can be a powerful driver to develop 4th generation district heating and cooling as the HeatNet NWE partner Mijnwater shows it. Read More

Developing a transition roadmap for Kortrijk

Posted on

The HeatNet NWE partner of Leiedal made a transition roadmap for the South-West Flanders region to research which kind of efforts are needed to make the region energy neutral and to further develop district heating in South-West Flanders. This transition roadmap for the region is a very useful exercise and during a workshop week a team of experts applied it to Kortrijk. Read More

CAP Construction and Mijnwater BV present 4th generation DHC to Wallonia’s municipalities

Posted on

CAP Construction and Mijnwater BV were at a capacity building workshop for public authorities organised by the Federation of towns and municipalities of Wallonia on 30th November 2018. The main topic was the energy performance of buildings, but district heating and cooling networks were in the spotlight too. Indeed 4th generation district heating and cooling are one of the solutions to supply decarbonised energy to low consumption buildings. Mijnwater, the Living Lab of Heerlen city, was presented in details: the low-temperature distribution network is used to produce, exchange and store energy coming from geothermal source (mine water) and waste heat. This a fully automatically controlled and demand driven system integrating electricity renewable sources. This workshop targeted a regional audience, which is why French was used instead of English.
