    Energy-efficient provision of sterilised drinking water

    When heating drinking water, 5 degrees cooler medium temperatures can lower heat losses by up to 13 per cent. Sterility has to be guaranteed, and Legionella occurrence must be avoided. A research project led by the Technical University of Dresden wants to prove this with extensive measurements and sample taking.  more...

    Energy centre supplies Giessen University Hospital

    Giessen’s municipal utility company and University Hospital have jointly constructed the first energy centre to be integrated into a local heating and cooling network. The newly developed combined cooling, heating and power system ensures an uninterrupted supply to the hospital. It saves 21.7 % of the primary energy and 33.6 % of the CO2 emissions.  more...

    Securely controlling dynamic electricity grids

    The construction of power plants that generate electricity from the wind and sun continues apace. In particular at high sea, but also in rural areas, there is still considerable development potential during the next few years amounting to several gigawatts. The load centres, however, are situated in the metropolitan areas in the middle and south of the country. It is therefore important to integrate the locally created surplus capacities in an intelligent manner.  more...

    University campus to become climate neutral

    An interdisciplinary research team has developed an energy master plan for the campus belonging to the Technische Universität Braunschweig. Various scenarios for developing the campus as far as 2020 have been created with the aim of reducing the primary energy consumption by 40% and, in the long term, facilitating the conversion to renewable energy. Planning principles have been developed for the renovation and urban development of the site that can also be transferred to other urban districts.  more...

    World’s largest electrolysis plant inaugurated

    The world's largest electrolysis plant of its kind has been created in Energiepark Mainz. It has an electrical connected load of six megawatts and can produce up to 1,000 cubic metres of hydrogen per hour from renewably generated electricity. The hydrogen produced can be stored on site, transported in tanks or fed into the natural gas network where it can be used at a later point for generating electricity or heat. The plant has now been officially inaugurated.  more...

    Preparing the electricity grid for electric vehicles and heat pumps

    The electricity grids in Germany have to be expanded to cope with decentralised generators and increasingly more large-scale loads. For grid operators it is therefore important to gain an overview of the necessary measures and their effectiveness even before installing new operating resources. Special simulation and planning tools are suitable for this. As part of the Novel E-Mobility Grid (NEMO) research project, scientists at the Fraunhofer Institute for Solar Energy Systems ISE have developed a software programme that can help to analyse and plan power grids.  more...

    Does the energy transition need energy storage systems?

    The fact that energy storage systems have a role to play in the energy transition is hardly controversial. But statements about the actual demand, competitive solutions and application scenarios sometimes contradict each other. The Fraunhofer institutes UMSICHT and IWES have examined studies on the topics of electricity storage systems and Power-to-Gas.  more...

    Thermal storage systems brought into shape

    Thermal storage systems that utilise zeolite are still very rare. In a research project, scientists have investigated aluminosilicates for their practical use in thermal storage systems. They have succeeded in significantly improving the energy density, cycle resistance and thermal performance. The research has led to the development of a thermochemical storage system for a CHP power plant.  more...

    Stable grid with 100 per cent green electricity

    In a power grid, the energy provided must always be equal to the power demanded. Only then can frequency and voltage remain stable. Ensuring this is the task of grid operators. But when volatile — meaning not arbitrarily adjustable — energy sources are the main sources of electrical energy, grid operators face a challenge.  more...

    Virtually linking mini-CHP systems

    Linked decentralised combined heat and power plants (CHP) and electric loads will be able to participate in the electricity market in the future by forming a regional and virtual power plant. This will compensate for power fluctuations and create more flexibility while being economic and efficient. The research association ‘Thermal and electric CHP linking’, coordinated by TU Dresden, presented their results.  more...
