The EnEff:Wärme Research Initiative
District heat plays a special role among the different forms of generation and/or supply of room heat, domestic hot water and process heat in the low temperature range. It opens up multiple possibilities regarding energy feed-in as well as primary energy saving and substitution which the competing decentralised heat supply (e.g. using gas, oil, etc.) does not offer in this form. District heating is versatile in terms of energy supply (fossil, renewable); it can be supplied in an ecologically sound manner either from waste heat sources (uncoupling from industrial processes), from cogeneration (cogeneration plants, combined heat and power plants, waste-to-energy plants, waste heat utilisation from conventional thermal power plants) or from renewable sources. District heating is important due to both macro-economic and ecological reasons. Increased use of district heating can only be achieved in the market environment if the economic and technological framework conditions improve. Technological innovation and future-oriented concepts and plans form the basis for the required consistent development of district heating supply and the opening up of new potential.
EnEff: Wärme promotes specific network optimisation with the aim of further increasing the share of local and district heating and integrating less densely populated areas into the supply network. This could be the future of central heat supply systems. District heating networks, so-called smart grids, are to become central building blocks in local energy management. Low-exergy technologies (LowEx) help reduce transmission losses. Furthermore, new adaptive cooling and heating networks offer starting points for the integration of renewable energy. Thermally-driven micro cooling systems, latent heat and cold storage facilities, ORC technologies or thermally-driven heat pumps: The use of modern building technology and the development of distribution technology and system components represent important aspects of the EnEff: Wärme initiative - just like intelligent control and measuring technologies. Together, they form a fundamentally new heat supply concept.
The support initiative of the German Federal Ministry of Economics and Technology
EnEff:Wärme will integrate previous research activities from energy-related building refurbishment, energy-efficient supply concepts and new energy technologies and make the most of synergies.
Project Management Jülich manages the bulk of the energy research subsidies on behalf of multiple German Federal Ministries. This includes the subsidy programmes for renewable energy sources, rational utilisation of energy and power plant technologies. In addition to this, it also makes its expertise available for important strategic interdisciplinary tasks.
Project Management Jülich is responsible for technical and administrative implementation of the EnEff:Wärme research initiative. It must be consulted on project outlines and applications for research funding from the German Federal Ministry of Economics and Energy.
