Fraunhofer study: Offshore wind energy garanties a stable and economic power supply in future

26.11.2013
More than 6 billion Euro per year can be saved in German power production costs provided all of the suitable areas in the North and Baltic Seas were used by offshore wind energy production.

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.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
