What is the problem?

Despite the 2015 Paris Agreement on climate mitigation policies, we continue to burn fossil fuels. 
One of the solutions at local scale is DH - district heating networks powered by renewable energy sources (RES) that adapt to the resources of each territory, whether it is solar, biomass, waste heat, heat pumps or geothermal energy.

The situation so far:
Only a handful of central European regions have so far introduced effective policies promoting high-renewables DH. EU incentive schemes have boosted this process, especially in areas not reached by natural gas or where wood biomass is locally available. However, a significant number of these investments is experiencing sustainability problems, both from a technical and economic perspective.

What ENTRAIN aims to achieve...

ENTRAIN wants to encourage the adoption of a systematic and efficient energy planning able to reduce the local carbon footprint, intensifying the use of RES. The two main goals: CO2 emissions reduction and the resulting improvement of the local air quality, alongside socio-economic benefits for local communities of the 5 key regions in Italy, Germany, Croatia, Slovenia, Poland.

...and how
This can be possible only through the growth of technical expertise, the start-up of investments and innovative financial tools.
It is necessary to take the example from the best in this field: Austria and Germany, regions with advanced planning capacities and long-term experience will give guidelines on heat planning and quality criteria. ENTRAIN will start 9 pilot local DH networks and 9 heat planning studies, together with the development of 3 innovative financial schemes and the adaptation and adoption of the Austrian “QM Holzheizwerke” quality management system.

ENTRAIN: “Enhancing renewable heat planning for improving the air quality of communities”


Project outputs:
the first step has been "preparing the local ground", with an initial survey of the target areas, guidelines for the evaluation of renewable heat potential and the actual evaluation for the 5 target regions.
These studies will be the base for the action plans and pilot projects.

QM Quality Management system documents and tools:
Our second step is the "knowledge transfer" from our Austrian and German partners, with QM Holzheizwerke (quality management for RES-district heating networks) translations and adaptation.

Let's learn from our expert partners! We have planned 5 train-the-trainers sessions in which the consortium and external guests are going to benefit from our German and Austrian partners' knowledge and experience in renewable district heating. Training is based on the QM system and guidelines but covers funding/economy, operation and optimisation, consumer relations, emissions/air quality, fuel and ash logistic as well.
The 2nd and 3rd trainings have been recorded: watch them HERE
