    New Energy Research Programme published

    The German cabinet has passed the new, 7th “Innovations for Energy Transition” Energy Research Programme. The programme replaces its predecessor from 2011. Content-wise, the programme builds on the successes of recent years, sets new courses and defines focal points for research funding and innovation policy in the energy sector. For the years 2018-2022, the German Government is budgeting 6.4 billion euros for energy research.  more...
     

    Enhancing performance of PV modules

    The output of solar modules is usually less than the cumulative performance of the solar cells installed in these. Various optical and electrical loss mechanisms as well as optical gains influence the output of cells integrated into the photovoltaic module. Researchers are looking for ways to enhance the performance of modules without modifying cells. This involves combining components in a way that ensures that the achieved module output is greater than the added performance of individual cells.  more...

    New knowledge portal for solar heating networks

    Large-scale solar thermal systems are being increasingly used in heating networks. The Steinbeis Research Institute Solites in collaboration with international partner organisations has created a newly designed information service on solar-supported heating networks at www.solare-waermenetze.de. At the heart of the web platform is a database that provides comprehensive technical and economic expert knowledge.  more...
     

    Sorting green waste and using it for producing energy

    In addition to the “Biotonne”, the organic waste bin used by German households for mainly disposing of domestic vegetable waste, the separate collection of coarse woody materials from garden and park waste could provide a significant amount of fuel for thermal utilisation. Scientists have investigated the potential provided by biomass that is better suited for combustion in CHP plants instead of composting.  more...

    Hydrogen for the urban energy transition

    A new, almost climate-neutral urban district is being built on the site of a former freight yard in Esslingen. Over a period of five years, scientists in the planned Neue Weststadt district are experimenting with an innovative energy supply concept with which electricity surpluses from intermittent renewable energies will be converted into hydrogen, stored and, if necessary, returned to the grid. The district will also serve as a real-world laboratory for the system-supportive coupling of the heating, cooling, electricity and mobility sectors.  more...
     

    CIGS thin-film modules beautify house walls

    In order to achieve the goal of meeting Germany's energy demand almost completely with renewables by 2050, it is planned that facades and partially shaded surfaces should also be used for generating electricity by photovoltaic means. The modules that can be used for building-integrated photovoltaics (BIPV) have to meet considerable requirements in terms of their appearance, performance and costs. Experts have summarised this need for action in their recommendations for the German federal government's 7th Energy Research Programme.  more...
     

    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...
     

    Photovoltaic elements for facades and flexible roofs

    Modern building facades can do more than provide insulation and outer envelopes for buildings. New photovoltaic modules give designers considerable scope when designing the colour of facade surfaces. Unlike standard solutions, such energy facades make a considerable contribution to improving the energy balance of buildings. Standard silicon, thin-film and organic PV elements can be used.  more...
     

    Solar water heater for ceramic granules

    The innovative CentRec radiation receiver has passed its first practical test at very high temperatures in the DLR’s solar tower in Jülich. The receiver uses ceramic particles as a heat storage medium. These are inexpensive, enable very high temperatures and can be handled with relatively little effort. The practical test at very high temperatures is an important step on the way to marketing this receiver technology.  more...
