Flexible Sector Coupling by Energy Storage Implementation
Dr. Andreas Hauer studied Physics at the Ludwig-Maximilians-University in Munich, Germany. He made his PhD at the technical University in Berlin. Now is Head of the Division “Energy Storage ” at the Bavarian Center for Applied Energy Research, ZAE Bayern, with about 80 emploees. There he is responsible for a number of national and international research 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 one working group on material development for thermal energy storage and another one on “Distributed energy storage for the integration of renewable energies (DESIRE)” within the technology network of the IEA. On the national level he is member of the board of directors of the 2012 established Bundesverband Energiespeicher (BVES), German Energy Storage Association. In this position he is responsible for R&D activities within the association.
The main input of renewable energy in our future energy system will come from wind and PV. When reaching higher shares of fluctuating renewables in the grids, renewable electricity can be distributed to other sectors, mainly the thermal and the mobility sector.
By coupling the sectors, electricity, thermal (heating and cooling) and mobility, the demand pattern of the “consuming” sectors, “thermal” and “mobility”, can help to better utilize the renewable input in the electricity sector. By implementing energy storage technologies between the sectors, the match of fluctuating supply and demand can be managed. Renewable electricity can be available on demand in the thermal and mobility sector. This can relieve local distribution grids and raise the usable share of renewables in general.
The following figure shows the flexible sector coupling approach:
