This article aims to investigate the advantages of DH in an intersectoral
context: offering versatile technology expansion options and therefore the ability to provide
flexibility to the electric system.
Making the energy transition a reality is going to be one of the key challenges in the coming years, and even more so for the heat transition which is still lagging behind. With the pathway to 2030 and 2050 set, we still have to decide on the levers and technologies to get us there. We are keen to know your opinion!
Several of TEMPO's innovations will be applied in Breschia's A2A demosite to verify their effects in an operational environment and to develop a solution that is easily replicable in low heat density parts of the networks.
An interesting energy cooperation solution can be found in Tuscany, where one can find an industrial area mainly composed of several tanneries and a shared wastewater treatment plant, managed by Cuoiodepur.
In the Achental Valley, a mountainous area located in the south of Germany, a heating grid has been installed driven by wood chip burning. The potential of using biomass in the region has been discovered during the European RES-Integration project.
In 2008, the Regional Municipality of Bornholm decided to become a 100% sustainable and CO2-neutral society in 2025, in which only sustainable and renewable energy is used. In 2019, already 60% of the island's energy is produced fossil-free by using wind, sun and biomass power. The island's green vision, big share of renewable energy, citizen and community involvement and replicability of the energy solution helped in winning the 2019 RESponsible Island Prize
Arcelor Mittal Ghent has a lot of residual heat, which is currently cooled down in order to discharge it in a canal or into the air. After an initial inventory and several calculations, a feasibility study was conducted to look at concrete possibilities for the local use of Arcelor Mittal's excess heat.
The city of Litoměřice developed an Energy Concept in 2009 and adopted a Municipal Energy Plan in 2014. The main goal of the municipality is to reduce energy consumption by 20 % by 2030 (baseline year 2012).
This case study covers the investigation of renewable heat supply options for the new development area «Teilraum 31» in Ansfelden. The area is mainly owned by the municipality which, therefore, can define priorities regarding energy efficiency and renewable energy.
Matosinhos’ (Portugal) year-round mild weather makes the challenge of decarbonising heating and cooling drastically different from more demanding climates, be it from a business-case as well as from a technical perspective. Residential heat demand has historically been low. It is expected that the improvements in the building stock will essentially result in an increase of the indoor temperatures, which are low, and therefore will contain any pressure to increase the demand.
As the district heating system in Herten is currently supplied with heat from coal-fired Combined Heat & Power (CHP), the approach was to frame a potential alternative mix of centralised heat supply units with a high share of renewable energy sources. It is aimed at designing a system which is technically feasible and to compare it to the current system with regard to the heating costs.
Odense wants to phase out the remaining 30% coal consumption in the heat production for the district heating network by 2025. In 2018, the coal consumption was already reduced from ~900.000 t/y in 2010 to 2-300.000 t/y but the goal is to substitute this completely.
