Storing heat until winter

To be able to use summer heat for heating during the winter, hot water storage systems have to be very large. Small storage systems cool down too quickly. With this in mind, seasonal storage tanks have been developed almost exclusively for housing estates or very large consumers. Now researchers have created a new long-term storage system which is also suitable for single-family homes.  more...

Mechanical mass production of rotor blades

The rotor blades of wind turbines are still mostly made by hand. This is due to the low piece numbers involved. So how would it be possible to produce them faster, cheaper and with a greater degree of precision? Automated production is now possible in the BladeMaker factory in Bremerhaven. Eight process steps are combined into a single step. The production facility has now been inaugurated.  more...

BINE interview with Professor Dr. Siegfried Heier

Further developments of converter technology will be necessary for wind turbines to support any grid improvements. Decentralised coupling and decoupling of power ought to be possible in the future high-voltage direct current (HVDC) electric power transmission system. In this BINE interview, Professor Dr Siegfried Heier lists future focal points of technological development in the wind energy sector.  more...

Pilot production launched for superconductors

He had to wait 30 years for this moment: Dr Georg Bednorz, a Nobel Laureate in Physics, was present in the Rhineland town of Rheinbach to see the pilot production of high-temperature superconductors begin. It is intended to provide further insights into the manufacture of these almost resistance-free conductors and pave the way for their large-scale series production. The technology is therefore taking a further step towards market maturity.  more...

Stadtwerke Augsburg testing superconducting fault current limiter

The ASSIST project shows how decentralised feed-in systems can be safely integrated into a medium-voltage network. Since 15 March, a superconducting fault current limiter ensures that the electricity fed from a cogeneration engine test rig into the electricity grid belonging to Stadtwerke Augsburg municipal utility company is protected against short circuits. Last week, Thomas Janetscheck from Stadtwerke Augsburg presented the system at the ZIEHL V superconductor conference in Munich.  more...

Thermoelectrics: power from waste heat

Waste heat is produced in all areas of daily life – in industry, homes and transport. In Germany alone, this adds up to a waste heat potential of 300 TWh per year. This energy volume corresponds to nearly half the total energy consumed by German industry. Thermoelectric generators (TEGs) can tap into this huge energy reservoir and transform the "waste energy" without moving parts into a higher form of energy.  more...

Coal gasification – efficient and flexible

Taken together with renewable energy sources, conventional power plants are of particular importance. Although the share of solar and wind energy continues to rise, conventional power plants will still remain necessary for the time being. But they need to be more flexible now: on the one hand, flexible in terms of their performance, and on the other in terms of fuel. Gasification of solid fuels is one way in which conventional power plants could be operated in the future. In the HotVeGas research project, scientists are examining the possibilities of this technology on a fundamental level. The third project phase is starting in January 2016.  more...

Energy storage systems in 2030

What role will functional storage systems play in the energy supply system of the future? Which system infrastructure can economically secure a reliable energy supply in 2030? And what measures must the government take so that this system infrastructure can prevail on the market? Scientists at the Research Center for Energy Economics (FfE) are trying to get to the bottom of these questions with an ongoing study. The results are now available.  more...

Modelling power supply for 2050

By 2050, the goal is for renewable energy sources to generate at least 80 per cent of power. In order to then still guarantee reliable supply at affordable prices, the entire energy system must be adapted and converted in a step-by-step process. The increasing share of fluctuating energy sources requires a flexible system that can react quickly. A research project demonstrates the degree of grid expansion, storage and new regulation opportunities that are technically required for this purpose, and which make economic sense.  more...
