报告摘要:
In order to realize the sea change of German energy policy (shut-down of all nuclear power stations in 2022) Germany installs huge capacities of wind-mills and photovoltaics.

The main problem is to make renewable energy like photovoltaics (PV) or wind able to replace the base load of electricity supply as it was done by nuclear power stations. This leads to energy storage.
The authors are convinced that medium to long term storage of large amounts of electrical energy is only possible by chemical storage. Hydrogen is suited but not in its pure state. One option is to use LOHC’s (Liquid Organic Hydrogen Carriers), chemical compounds that exist in an energy-lean state (not hydrogenated) and in an energy-rich state (hydrogenated). To find such a pair of chemicals is a challenge for thermodynamics and chemistry.LOHC’s use the infrastructure of liquids like domestic fuel oil.

The lecture highlights the basic research and the application in decentralized local storage of electricity and in mobility. Demonstration units should be available end of 2013. Because the electrical energy is partly converted to heat during storage, the authors follow the goal of storage-heat-coupling (SHC), thus making the heat available for house heating or cooling.

This approach reduces the dependence of Germany from outside energy imports.

报告人简介:
Wolfgang Arlt (*21.5.1952) studied chemistry and chemical engineering in Dortmund from 1970 on. He received his Dr. degree at this university about a thesis in the field of thermodynamics (grade: summa cum laude, the best possible grade) under the supervision of Prof.Onken. Since March 1st 1992 he is a full professor, first at the Technical University of Berlin for the chair of Thermodynamics and Separation. He accepted an offer by the university of Erlangen at April 1st 2004.

W.Arlt served the community in several functions (as a selection):
Chairman of the German group “Fluidverfahrenstechnik” in VDI-GVC (1996-2002)
Chairman of the Dechema working party “liquid chromatography” (-2003)
German delegate at the European working party of chemical engineering
Editor of the journal Chemie-Ingenieur-Technik
Main referee of the German National Science Foundation (DFG)
Member of the Korean-Japanese society of chemical engineering

His Chair of Separation Science & Technology in Erlangen performs research in separation problems that stem mainly from life sciences based on sound thermodynamics.

His work on phase equilibria with polymers aim at the separation of different polymers (polymer recycling) and the production of fine polymer particles.

Further activities are in the field of energy engineering, mainly thermodynamical analysis and capture of CO2. On a larger scale, unit operations are applied to the search for technical tools against climate change (scrubbing solvents, storage option in rocks).

The recent activities are in energy engineering: calculation of chemical reaction equilibria and chemical storage of electricity.
