    Modern living in an historic urban district

    The Margaretenau residential district in Regensburg is being modernised to improve its energy efficiency. The designers are developing a solar-active and -adaptive exterior render system as a replacement for conventional thermal insulation for the facades. This should increase the solar yields and improve the thermal comfort inside the buildings. The energy supply will be provided by a new and efficient hybrid heating system consisting of cogeneration and heat pump technology.  more...
     

    When are flexible district heating systems beneficial?

    The integration of thermal storage in cogeneration plants leads to more flexibility in district heating networks because the power generation can be better adapted to the power requirements. Power-to-heat systems couple the electricity and heating sectors to utilise renewable electricity for district heating. Together with partners from science and industry, researchers at the TU Berlin have investigated when the construction of heat storage and power-to-heat systems can be economically and ecologically beneficial.  more...
     

    “Solar thermal energy is becoming an integral part of district heating”

    Traditional district heating is converging with solar thermal energy: researchers and engineers presented new technologies for integrating solar thermal systems into the heating provision at the German Federal Ministry for Economic Affairs and Energy's status workshop entitled “Solar thermal energy in district heating”, which was held at the end of September in Dresden. In addition, the workshop also provided insights into current developments in Europe and worldwide.  more...
     

    Local electricity networks become flexible and resilient

    For three years, the Saarlouis municipal utility company, together with partners from science and industry, has worked on the development of what are known as resilient poly-networks. These autonomous electricity networks at the local level are designed to adapt dynamically to the respective network situation in order to ensure optimum supply. The findings were recently presented at a concluding event.  more...
     

    New low-emission marine engines

    The operation of ships causes considerable pollutant emissions. Future ship propulsion systems must therefore be more environmentally friendly. One possible way is to operate engines with natural gas rather than diesel. They have lower emissions when compared with current diesel engines without exhaust after-treatment. Researchers are developing and testing components and control instruments for this economical new generation of engines. They are aiming to reduce the engines' CO2 emissions and halve them in future.  more...

    Syngas from biocoals

    Organic waste, thinning wood, straw and landscape management waste products are still little used for generating energy. This is because such biogenic residues have poor combustion properties owing to their inhomogeneous composition or high moisture contents. However, researchers from the Technical University of Munich and SunCoal Industries are now producing biocoal from such material using a new process.  more...
     

    "We have to increase our efforts!"

    The first ENERGIEWENDEBAUEN conference took place in Berlin from 30 - 31 January, 2017. Some 350 participants from research, academia, architecture and planning offices, politics, energy suppliers, cities and municipalities as well as the real estate industry discussed how the energy supply of buildings and districts could be made future-proof. The aim of the German federal government is to create a climate-neutral building stock by 2050. This will not be easy to achieve.  more...
     

    Networked micro-CHP plant in field test

    Small engine-based cogeneration plants and fuel cells can be combined together and operated as a network. Such a regional virtual power plant (RVPP) is currently being tested by researchers at the TU Dresden and EWE AG in the Oldenburg area. They are developing control and regulation concepts for operating in networked systems until the end of 2017.  more...

    Pilot production of thermoelectric modules

    Thermoelectric generators convert waste heat directly into electricity. They utilise temperature differences and are paving the way for more energy-efficient production processes. However, the technology has previously led a niche existence because the module production is labour-intensive and therefore expensive. Researchers from Freiburg now want to improve this.  more...

    Fuel cell generates electricity and heat for homes

    Highly efficient, low-emission and quiet: as small-scale combined-heat-and-power stations, new fuel cell heating units produce heat energy and electrical energy with an efficiency of over 90 per cent. They have proven themselves in extensive tests in single and two-family homes, and their operation and design have been improved incrementally. The first units are now on the market. They run on natural gas, and on hydrogen and methane produced using renewable energy or biomass. Decentralised fuel cells can generate demand-oriented electricity, and they can be used in a grid-friendly or grid-independent way.  more...
