This is the result of a Fraunhofer IWES study commisioned by the Offshore Wind Energy Foundation. The IWES research team around Dr. Kurt Rohrig has analysed three scenarios. In one of them, a focal point was set on offshore wind energy, whereas in the other ones priorities where onshore wind energy or photovoltaics.

If offshore wind energy is gradually extended from today’s 3 Gigawatts (GW) of installed and currently under construction power up to 54 GW in 2050, total costs for the power system are reduced by 900 Million Euro compared to rapid expansion of onshore wind energy, and even by 6.1 billion Euro compared with a photovoltaics-scenario.
As much as 92 % of this cost advantage account for so-called flexibility costs. When electricity generation varies very much, the costs of compensation by storage, back-up power plants and derating of unusable power are higher. Offshore, howewer, the wind is blowing so constantly that at 340 days of the year electricity can be generated. In addition, the power level can be predicted more accurately than onshore.
Therefore, offshore wind turbines can provide ten times more balancing capacity in order to smooth power supply than onshore systems, and costs are only one quarter. Furthermore, considerable cost savings could be achieved by a North Sea offshore grid for Belgium, Denmark, Germany, the UK, the Netherlands, and Norway that facilitates electricity trade.Expert contact:

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
