The integration of distributed and non-dispatchable renewable energy into the wider energy system (electricity, heat/cold and transport) poses significant challenges for the design and operation of the energy system. For example, due to the increasing fraction of non-dispatchable generation it becomes more important to provide novel mechanisms to balance supply and demand. Energy storage is one of the enabling technologies for future, low carbon energy systems and can provide wide-ranging benefits such as peak shaving, frequency regulation and load shifting.
The Energy Storage Discussion Group brings together researchers with different backgrounds working on energy storage related topics and provides a platform for discussions of inter-disciplinary concepts. Current members of ESDG are from the Institute for Energy Systems (IES) but we invite anyone interested in energy storage to join this discussion group.
ESDG members meet on a regular monthly basis; at every meeting we present and discuss recent journal publications on energy storage and current research. The main purpose of our meetings is to provide an opportunity to present new concepts, methods, technologies and challenges in the area. Each presentation typically lasts 10-15 minutes, followed by a 20-30 minute discussion. At every meeting two presentations are given: one about a journal paper not from this research group and one about current research in this research group. The presentations and the meetings in general are informal, but we follow strictly the following rules:
- The papers must be energy storage related, but the exact topic can be anything from battery storage, to thermal storage and system integration. This facilitates widening of the horizons of the ESDG members, while staying within the topic of energy storage.
- The presented papers must be transactions-quality publications (to ensure high quality of presented material).
- The papers must not be authored by the presenter or any other ESDG member[*] (to facilitate cross-fertilisation and introduction of new concepts and ideas).
- Everyone gets to and has to present a paper every now and then!
- The current research should really be current with open questions, challenges and problems.
[*]: The only exception to this rule is when, occasionally, we use the ESDG meetings as a test run for conference presentations to be given by our members.
