"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...

Fresh air without mechanical ventilation

Ventilating non-residential buildings naturally but in a controlled manner saves primary energy and requires lower investment and operating costs than mechanical ventilation systems. Scientists from Stuttgart University have therefore developed a ventilation concept that ensures a good indoor environment and reduces the electricity consumption for operating the ventilation system.  more...

Cheaper production of solar cells

There is intense competition in the market for photovoltaic systems. With constantly new innovations, the manufacturers are reducing their production costs and are increasing the efficiency of the cells and modules. For this purpose they are improving the production processes along the chain from silicon to the module. Companies and research facilities are working together to produce high-quality silicon crystals and wafers that save as much material as possible. They are also improving the material quality using an innovative solidification process for quasi-monocrystalline silicon. And with a new separation process they are producing more wafers from the same amount of silicon.  more...

New wind energy test field in southern Germany

Because of the pronounced terrain structures, wind farms in low mountain ranges have to cope with more turbulent wind conditions than in lowland areas. These meteorological conditions mean that development and maintenance costs have been higher up to now in landlocked mountainous areas, while precise profit forecasts are more difficult. A new wind energy test field belonging to the southern German research group WindForS now aims to close the gaps in meteorological knowledge and optimise the wind turbine engineering.  more...

Networked factory stabilises the grid

The factory of the future is flexible and networks the energy flows between machinery and buildings. The so-called Phi Factory is not only very energy-efficient, it also helps stabilise the electrical supply grid. The new model factory relies on a high share of renewable energy and helps smooth out electricity supply fluctuations.  more...

Impact of defects can be calculated

Large wind turbine components are made of cast iron with spheroidal graphite. During their production, however, chemical reactions can cause defects. These casting defects are called dross and their impact on component lifetime has, to date, only been evaluated using assumed material characteristics. There is a measure of uncertainty involved in providing evidence of their occurance. New non-destructive test methods should now be able to evaluate dross more reliably.  more...

Solar thermal and photovoltaic power plants in comparison

How will the market for photovoltaic and solar thermal power plants develop in the coming decades? Which technology is economically more efficient? And what opportunities are offered by combined power plant systems in sunny regions? A study carried out by the German Aerospace Centre (DLR) has investigated the development of these power plants until 2030.  more...

Learning and working in an energy-plus school

Uhland School in Stuttgart, which dates back to the 1950s, no longer accorded with today's structural and energetic standards. The renovation work is now almost complete and the City of Stuttgart is getting its first energy-plus school. A photovoltaic system on the roof and façade of the building covers the electricity requirement.  more...

Superconductors for the medium-voltage grid

Scientists are testing the longest high-temperature superconducting cable in the world under real conditions in Essen. One kilometre long, it connects two substations in the inner city. It replaces a conventional 110 kV line and renders one substation in the inner city obsolete. After two years of testing, it has passed the field test. It could be a blueprint for the future power supply system in urban areas.  more...

Concrete sphere in the sea successfully stores electricity

How can energy be stored near offshore wind farms in the future? Researchers have developed a new storage system that works with hollow spheres on the seabed. The principle is similar to conventional pumped storage power plants. At the end of 2016, the researchers at Fraunhofer Institute for Wind Energy and Energy System Technology IWES tested a three-metre concrete prototype in Lake Constance. The test results are highly promising.  more...
