DSM and Lightyear aim to design solar roofs for all types of electric vehicles
Today more than 50 % of our final energy demand in developed countries is thermal – either heating or cooling demand. Concerning CO2 emissions it shows a similar picture: The thermal sector causes twice the amount of emission as the mobility sector! Projections for our future energy system show, that thermal energy will become even more relevant. In this context thermal energy storage technologies can contribute substantially to the integration of renewable energies and to an increase in energy efficiency and by this finally to the reduction of CO2 emissions.
The available thermal energy storage technologies are able to match the diversity of possible in the building and industrial applications. Technology developments in all thermal storage approaches – sensible, latent and thermochemical – were quite impressive over the last years. However the always changing requirements for possible application fields have to be taken into account as well. The presentation shall bring together and illustrate latest technology innovations and new application requirements.
The general trends in our energy systems – rising fraction of renewable energies and the holistic approach to overcome sector boundaries – offer new possibilities for thermal energy storage. Thermal energy storage solutions can substantially contribute to the integration of renewable sources, may it be directly from solar thermal or by power-to-heat technologies from PV or wind power. In addition to that sector coupling offers new options for promising applications of thermal storage systems. In conjunction with the electricity sector thermal storage can utilize higher temperature levels, which enables innovative high temperature storage approaches to evolve. Latest developments and actual examples will be presented.
Dr. Andreas Hauer studied Physics at the Ludwig-Maximilians-University in Munich, Germany. He made his PhD at the technical University in Berlin. Now he is the Chair of the Board at the Bavarian Center for Applied Energy Research, ZAE Bayern, with about 100 scientists. There he is responsible for all national and international research and development projects focussed on thermal and electrical energy storage, thermal driven heat pumps / chillers for industrial and building applications. Dr. Hauer is an international known expert on energy storage in general and specialized on thermal energy storage. For 7 years he was the secretary of the Executive Committee of the Energy Storage Programme within the International Energy Agency, IEA. At the moment he is leading working groups on material development for thermal energy storage and on “Flexible Sector Coupling by the Implementation of Energy Storage” within the technology network of the IEA and he is member of the Executive committee. He is member of the Board of Directors of the International Solar Energy Society, ISES. On the national level, he is member of the Board of Directors of the 2012 established Bundesverband Energiespeichersysteme (BVES), German Energy Storage Systems Association. In this position, he is responsible for R&D activities within the association. He is Editor in Chief for the Wiley publication “Advances in Energy Storage”, which will be launched in 2021.
