    Electrostatic precipitator reduces emissions

    Boilers powered by biogenic fuels emit more particulate matter than oil and gas boilers. In order to safely undercut the stricter limit values in all operating states, which have been in place since the beginning of 2015, researchers and plant manufacturers are working together to achieve the emission-reduced operation of biomass heating systems by means of secondary emission reduction measures.  more...
     

    Kom.EMS for standardised energy management

    Energy agencies of the German Federal States of Baden-Württemberg, Saxony, Saxony-Anhalt and Thuringia have developed a tool under the name KOM.EMS for establishing and operating an energy management system for municipal administrations. The tool aids in evaluating, optimising and perpetuating energy management. The online tool was unveiled to the public on 13 September.  more...
     

    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...

    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...

    National 5G Energy Hub project launched

    Last week, TU Dresden officially launched the long-term National 5G Energy Hub research project. This is aimed at making the future 5G mobile standard usable for applications in energy technology. Project partners are TU Dresden in cooperation with RWTH Aachen, Deutsche Telekom and Ericsson. In addition, the associated partners Techem, VDZ, E.ON and the city of Dresden are also involved.  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...
     

    Grid-supportive buildings and districts

    The expansion of renewable energies requires increasingly flexible, complementary power generation as well as flexibilisation of the electricity demand from consumers. In addition to traditional electricity-to-electricity storage systems and flexible power plants, buildings can also play an important role in shifting electricity demand.  more...

    Test methods for practical key system figures relating to energy efficiency

    Measurements on real heat generator plants show that efficiency parameters as determined by calculation sometimes deviate considerably from the values registered by measurement technology. This is especially true for heat pumps and micro CHP plants. The annual performance factor is decisive in terms of their economic success.  more...
     

    Developing multifunctional façade elements

    As the outermost layer of the building envelope, the façade performs numerous functions. They are to be intelligently combined to create a system that permits the application of cost-effective, multifunctional façade systems. To do this, scientists are developing a façade element with integrated organic photovoltaics, textile sun protection, a sustainable insulating material and the sensors necessary for control. The next step is to test the elements on the south façade of a multi-storey residential building.  more...
     

    Smart Green Tower becomes an energy producer

    The Smart Green Tower is being built in the city of Freiburg. The 51-metre-high building will provide living, residential and working space. Depending on the solar radiation, a building envelope made of photovoltaic modules generates more energy via the photovoltaic system than can be consumed directly. In order to utilise the surplus electricity, the designers are using a flexible internal energy storage system with lithium-ion batteries.  more...
