    Adjusting operation of biogas plants to power requirements

    Compensating supply fluctuations will prove vital in future power grids utilising high proportions of wind and solar energy. The demand driven generation of electricity from biogas can make a viable contribution in this regard. Researchers are developing new systems and software for biogas plants, integral in facilitating such flexible operational characteristics. This involves the precision monitoring and regulation of biogas production and conversion into electricity.  more...

    Which heat sources are optimal for heat pumps?

    The number of buildings heated by heat pumps continues to rise. In recent years, air-water heat pumps have been the dominant force in this regard. More energy efficient alternatives exist, however, to outside air as a heat source. Examples include geothermal energy, ground water, exhaust air and solar thermal energy. The variety of potential heat sources and of heat exchangers tapping these presents an incredible challenge for planners. Validated concepts, objective decisionmaking guidance and analyses are consequently called for. This endeavour is supported by two research groups.  more...

    Mainz Energy Park

    Companies and scientists are investigating the storage of fluctuating wind energy in the form of hydrogen on a research plant located in the Mainz-Hechtsheim commercial zone. All key components from generation and storage to utilisation at an industrial scale are being looked at and interlinked with innovative technology components. The PtG plant (Power-to-Gas) at megawatt scale facilitates not only the chemical long-term storage of energy. It furthermore interconnects the electricity, heat and mobility sectors.  more...

    Double heats better

    Air-to-water heat pumps are providing increasingly more heat for new or refurbished single-family homes with low energy requirements. Compared with ground source heat pumps, they have significantly lower acquisition costs and can be easily integrated into low-temperature heating circuits. Scientists from research and industry want to increase the efficiency of the systems by, on the one hand, using a second heat source for the heat pump and, on the other hand, by reducing the heat demand by means of centrally controlled individual room and supply control systems.  more...

    Energy efficient model factory

    A multi-functional, multi-networked factory in every respect: The ETA Factory on the campus of the Technische Universität Darmstadt is a research project, large-scale demonstrator and place of learning. It networks the building envelope and industrial process chain across technologies and disciplines in individual and integrated solutions, thus increasing the energy efficiencyof the overall system.  more...

    District heating network becomes heat hub

    The Brandenburg town of Hennigsdorf wants to increase the climate-neutral share of heat in its district heating network to 80 per cent within five years. To achieve this, the municipal utility company is planning to integrate the waste heat from the local steelworks and large solar thermal collectors into the network. A multifunctional, large-capacity heat storage system is intended to provide the necessary flexibility. The concept is ready and the implementation has already started in 2017. Hennigsdorf is therefore acting as a real-life laboratory for ensuring the renewable future of the heating provision.  more...

    Material loading in flexible power plants

    The conditions for operating conventional coal and natural gas power plants are changing considerably as a result of their combination with renewable energies. In future they will run more frequently under partial loads, have considerably more start-up and shut-down cycles, and the components will be subjected to greater and more diverse loads. Scientists have investigated the thermal and mechanical loads on thick-walled components in power plants under the new conditions. At any given safety level, the aim is to more precisely calculate the stability of components in regard to their damage and thus economically optimise their deployment times.  more...

    Keeping the oil in the engine

    Each time the fuel-air mixture is ignited in petroland diesel engines a small portion of the gases flows from the combustion chamber into the crankcase as leakage current. For the engines to function optimally, it is necessary to dissipate these so-called blow-by gases and separate the engine oil droplets contained within them. This reduces the pollutant emissions and oil consumption of the engines. For modern, higher-compression engines, researchers have developed new and effective separation systems that undercut the more stringent emission limits for oil mist.  more...

    New building services concept tested in hotels

    The conversion of a residential building to a hotel in the centre of Munich focussed on comfort and energy efficiency. The building envelope almost achieves the passive house standard following the renovation. The system technology is adopting a different approach: decentralised heat pumps produce domestic hot water and space heating heat on a room-by-room basis. A twin-pipe chilled water network balances out the heat and cooling requirements between the individual rooms.  more...

    Rain can damage rotor blades

    Rain and other weather and environmental factors can have a detrimental effect on the rotor blades of wind turbines in the long term. The leading edges of the blades are particularly susceptible to damage. Here the protective layer erodes first and material degradation subsequently continues deeper into the blade structure. A new test stand is now investigating the mechanisms involved in rain erosion in detail. The aim is to provide better protection for rotor blades in the future so that they can be used longer, thus improving the economic viability of wind turbines.  more...
