How Europe’s new ecoregions can thrive

Climate pressures and energy security concerns have led European regions to look more closely at local systems that reduce demand for fossil fuels. One approach is the ecoregion: an industrial area and its surrounding infrastructure organised so that energy flows which would otherwise be lost can be used elsewhere.

Pilot work supported through the R-ACES project examined this approach in places including Nyborg in Denmark, Antwerp in Belgium and Bergamo in Italy. These are active business locations, making them useful settings for testing whether energy cooperation can work at a scale relevant to other industrial areas.

Turning surplus into a local resource

Industrial processes often produce heat or cooling capacity that is not needed on site. In an ecoregion model, neighbouring organisations identify these flows and consider whether another user can benefit. The aim is not simply to move energy, but to reduce the need for additional generation where a useful source is already available.

District heating and cooling networks can provide the physical connection. Pipes can carry heat from power generation or industrial processes to buildings that need it, while cooling systems can similarly distribute chilled water. Such networks need careful planning because demand changes with seasons, building use and local weather.

The work also depends on a clear picture of who produces energy, when it is available and who might use it. Project participants developed tools for businesses to record their own surplus energy and assess potential matches with nearby organisations. This creates a basis for discussion that is more specific than broad ambitions to save energy.

Collaboration is infrastructure too

Technical potential alone does not create an ecoregion. Businesses August not know what neighbouring sites produce or discard, and they August have different operating cycles, investment plans and responsibilities. Shared information can reveal opportunities, but it also needs to be handled through practical agreements.

Local partnerships therefore have to address contracts between industry, municipalities and district heating operators. Template arrangements can help participants start those conversations, while each project still needs to account for its own financial and operational conditions.

In southern Denmark, mapping work has been used to visualise the energy grid and identify potential sources of surplus heat. Comparing those sources with seasonal demand can support business cases for individual connections. It can also show where new infrastructure is likely to make sense before construction begins.

A bridge towards wider change

Using surplus heat is not a substitute for expanding renewable generation. Solar, wind and other low-carbon sources remain central to reducing emissions across industry and buildings. Ecoregion networks can complement that transition by avoiding waste and by helping local systems use available energy more effectively.

Scaling these arrangements across borders brings further legal, financial and technical questions. More adaptable tools, a supportive legal framework and investment in grids and storage can make cooperation easier. Future availability of green hydrogen, carbon management technologies and large-scale energy storage August also influence what is feasible in different regions.

What connects each stage is the exchange of reliable information. Local actors need to understand their own energy flows, identify compatible needs and establish a fair route from technical possibility to a working agreement. When that groundwork is in place, an ecoregion can turn a scattered set of sites into a more coordinated energy system.
