The Europäische Akademie's Spring Conference on renewable energy sources

12.04.2010
Supply security and compliance with long-term CO2 reduction targets?

The proportion of renewables in our energy supply is steadily growing, due in part to fixed feed-in tariffs meant to promote climate protection.

These tariffs are aimed at reaching political targets regarding the proportion of renewables in the overall energy supply. For technical reasons, power inputs and outputs must be balanced at all times, in order to avoid network failures and ensure the required quality standard of the generated electricity.

Since the amount of fed-in electricity of most currently viable technologies depends upon wind speeds or solar radiations in a given location at a given time, the use of renewables comes with a certain number of imponderables which need to be discussed and clarified.

Therefore, the Europäische Akademie held its Spring Conference on the topic of "Secure electricity supply and renewable energies. Supply security with meeting long-term targets for CO2-emission reduction?" at the Bonn Wissenschaftszentrum (Science Centre) from 24-26 March 2010.

The conference was opened with a public evening lecture by Professor Dr. Kornelis Blok (Utrecht University) on the status quo of scientific and political discussions regarding scenarios of the future and climate protection targets and the claimed contributions of the global supply of energy.

During the first main section of the conference, Dr.-Ing. Joachim Nitsch (German Aerospace Centre DLR, Stuttgart) presented, amongst others, the German Federal Environment Ministry's "reference scenarios".

They demonstrate how Germany could reach its targets by 2050 with an extensive use of renewables. The scenarios make evident how those goals can be reached based on set presuppositions, e.g. for technology development. Adj. Professor Dr. Dietmar Lindenberger (University of Cologne) presented the results of grid studies by the German Energy Agency (dena). He discussed ways of integrating wind power stations into the German electricity supply by the year 2015 or respectively 2020/2025 and emphasised the necessity of a European perspective for the efficient expansion of the use of renewable energies.

The conference also focused on the technical means of balancing out electricity in- and output by enhancing electrical grids and introducing electricity storages. First, Professor Dr.-Ing. Christian Rehtanz (Technical University of Dortmund) presented the challenges and opportunities of integrating renewables into electrical power supply grids: Grid bottlenecks and the current lack of flexibility within power distribution networks could be solved, for instance, by means of co-ordinated load-flow regulations, DC transmission lines and end customer participation. Furthermore, Professor Dr. Dirk Uwe Sauer (RWTH Aachen University) presented an overview of the options and fields of application for storing electrical energy, and developed a technology scenario using primarily hydrogen and pumped storages for creating a balance over a span of several days; for shorter time periods, systems such as batteries of electric vehicles, thermal storage systems and Smart Grid Management may be conceivable.

The section was concluded by Professor Dr. Dr.-Ing. Hans Müller-Steinhagen (German Aerospace Centre DLR, Stuttgart/University of Stuttgart) who explained the Desertec concept, an industry initiative for secure and environmentally-friendly power supply and its integration into a power union of EU and Mediterranean countries (MENA). To ensure a consistent power feed, solar thermal power plants, for instance, are combined with efficient heat storages and DC transmission lines.

The third section of the conference looked into the legal and economic framework conditions for inte-grating renewable energies. Professor Dr. Thomas Ziesemer (University of Maastricht) first discussed the economic framework conditions of market economies and proposed to fundamentally rework them. Professor Dr. Jens-Peter Schneider (University of Osnabrück) dealt with current legal regulations and options for setting the course for sustainable energy systems against the backdrop of current German and European legal frameworks, e.g. the responsibility question for the construction of storage facilities and conflicts of use regarding storage media such as gas caverns. Industry representatives (EWE, citiworks, E.ON, RWE) concluded this section with comments on the subject. They discussed approaches to the integration of renewable energies and raised unresolved questions.

It became evident that, although concepts and technologies for integrating renewable energies do exist, they require further expansion and development. Due to the long-term nature of the development and implementation of individual technical measures along with the possibly necessary structural adaptations of markets and the regulation of electrical power grids, supporting concepts and measures for such an integration must be developed further and implemented along with the promotion of power generation from renewable energy sources.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
