Differentiated assessment of economic benefits

Nowadays, it is relatively easy from an engineering viewpoint to construct buildings with extremely low energy requirements. However, is it also possible to achieve this energy level, which is ambitious in terms of planning, building technology and commercial considerations, with existing buildings on a large scale? And is this advantageous from a financial point of view? In the BINE interview, Professor Thomas Lützkendorf from the Centre for Real Estate at the Karlsruhe Institute of Technology (KIT) discusses the statutory framework conditions, calculation methods and data bases for transparently determining the economic benefits of energy-optimised buildings.  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...

“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...

Refrigerators stabilise the electricity grid

Refrigerators that consume electricity precisely when the wind and the sun provide excess electrical energy, and which during slack periods maintain their cooling temperature without additional energy input, would greatly relieve the grid. Scientists from ZAE Bayern are investigating the costs and benefits of such a load shift together with industrial partners. For this purpose they are increasing the thermal inertia of an efficient standard refrigerator by installing latent heat storage units. The test device can thereby bridge longer standstill times.  more...
