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...

Virtual further development of system technology

A current challenge for the wind industry is to counter the economic pressures from the electricity market with innovative concepts. However, the route that needs to be taken until new turbines and components reach market maturity is long. In order to save time and expensive phases on the test rig, many investigations can be simulated in advance on the computer. The new WindMUSE simulation environment is multidisciplinary, integrates existing submodels using a common language and enables real-time testing. The aim is to depict wind turbines with a precision comparable to that customary in the aviation industry.  more...

Sphere storage system receives German Renewables Award

One year ago, scientists sank a concrete sphere one hundred metres below the surface of Lake Constance. The three-metre-diameter hollow body provided a functional model for an offshore pumped storage power plant. Now they have received the “German Renewables Award 2017” for their research work. The developers at Fraunhofer IWES are already planning the next step.  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...

Foundry utilises waste heat from the melting furnace

Together with industrial partners, researchers at ZAE Bayern are developing a cost-effective energy storage system for industrial waste heat. It shall enable discontinuously generated waste heat to be utilised for processes for which this has previously not been done for economic reasons. The implementation phase has now begun. The scientists want to put a demonstration plant into operation in the spring of 2018. It will be used to provide the waste heat from a foundry melting furnace from the metal industry as process or thermal heat.  more...

Better insulation ensures more reliable operation

If the receiver insulation is damaged, the efficiency of solar tower power plants decreases. Repairing or replacing the insulation takes time and money. In conjunction with industrial partners, scientists at the German Aerospace Center (DLR) have developed cavity insulation that utilises new material combinations. Tests show that the market-ready insulation is more robust than previous models.  more...

Night-time electricity from solar thermal power plants

Together with the industrial partner Linde AG, researchers from the German Aerospace Center have further developed a latent heat storage system based on nitrate salts. In combination with a cascade of sensible heat storage units, the goal is to maintain the electricity production of solar thermal power plants at night and at times with low solar irradiation. To this end, the scientists have developed a storage system that can also be used for conventional steam power plants and industrial processes.  more...

Closing security loopholes in power grids

The way in which electricity distribution networks operate is changing considerably as a result of the energy transition. Decentralised systems are increasingly being connected via the Internet with the central control rooms of the energy providers for control purposes. The risks that can arise due to security loopholes in the information system are accordingly growing. In a guide, researchers at Bremen University of Applied Sciences show how the operational management can be secured and how the risks can be limited if measures fail.  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...
