Berlin, bcc Berlin Congress Center, November 18-20, 2013

Due to the enormous successes of past IRES Conferences EUROSOLAR and the World Council for Renewable Energy (WCRE) has strengthened the IRES series in collaboration with EnergieAgentur.NRW and numerous other partners. Over 500 participants gathered at the 8th International Renewable Energy Storage Conference and Exhibition (IRES 2013) at the bcc Berlin Congress Center, November 18-20, 2013.

The conference series has emerged as the central platform for sharing knowledge and exchanging ideas on a key issue of future energy supply, having attracted more than 3,500 participants since its beginnings in 2006.

Thank you to all speakers, poster presenters and participants of IRES 2013!

Conference Summary

"Energy storage technology to transform the energy system"

2013 11 18 IRES berlin-event-foto 0118At the end of November 2013 and with a few changes, the International Renewable Energy Conference and Exhibition (IRES 2013) was successfully held for the 8th time at the bcc Berlin Congress Center at Berlin Alexanderplatz. Over 500 participants from Germany and 36 additional countries gathered for this annual forum in a pleasant atmosphere. They accessed and discussed fresh insights into a fundamental building block of the energy turnaround – energy storage for power fluctuations from renewable energy sources. Approximately one third of the attendees were from European countries other than Germany and from countries outside Europe. This demonstrates the significance of the conference series as an international assembly of leaders from the energy storage industries, renewable and conventional energy businesses, science, associations, politics and the financial industry worldwide.

EUROSOLAR and the World Council for Renewable Energy (WCRE) put up IRES 2013, in collaboration with EnergieAgentur.NRW, VRD Stiftung für Erneuerbare Energien, and with the support of numerous additional partners.

Over a hundred speakers and nearly 80 poster exhibitors shared their experiences from research and user projects on the newest and advancing energy storage technology. They analyzed the political and economic framework conditions and discussed the need for storage from the renewable source in the power, heating and transport and mobility sectors with the attendees.

Hermann Scheer, founder and President of EUROSOLAR (1988 – 2010) first established the IRES in 2006. Early on he made the public aware of the relevance of storage of fluctuating electricity for the future high contribution of renewable energy to our power grid. The IRES conference series is hugely successful and a lot of the credit is owed to its numerous supporters. EUROSOLAR and the WCRE would like to say thank you to all partners and a special thank you to the members of the Scientific Steering Committee for their contribution to the IRES conference program and to the quality of the papers and presentations.

In the opening session EUROSOLAR President Prof. Peter Droege provided evidence of the environmental and (geo)political ramifications of the current fossil/nuclear based energy system with striking images and figures. He used his advocacy of transforming the energy system to make people aware of the need to discuss energy storage in connection with regenerative sources of energy and to prepare participants for the IRES.

2013 11 18 IRES berlin-event-foto 0082Johannes Remmel, Minister for Environment in the North Rhine-Westphalia state parliament said: "to integrate renewable energy in the power generating sector, a sea change towards a decentralized energy system is needed: energy storage will play a major role in the process, as will expansion of the grid, enhanced flexibility in conventional power generation and load management. Short-term energy storage technologies are useful options already at present. For a future increasing share of renewable energy long-term storage, such as hydrogen-based technology, will also be needed."

Prof. Eike Weber, Fraunhofer Institut für Solare Energiesysteme (ISE), President of the Bundesverband Energiespeicher (BVES) founded in 2012, presented simulations of future electricity generation in connection with the different storage technologies and thus provided an introduction and overview of the conference theme.

For three days, the IRES 2013 participants were offered an even more diverse range of expert forums than in recent years. In light of the many aspects of energy storage to be addressed, it became necessary to increase the number of sessions running in tandem this year from 3 to 4. New for 2013 also was that exhibitors had the opportunity to highlight innovations in the form of short presentations. A one-day German language user forum -held against the background of Germany’s rapid development of renewable energy- met with great interest from the attendees on day two of the conference. 2013 11 18 IRES berlin-event-foto 0387The practical examples presented span from combined virtual power plants with pumped hydro storage, solar-PV home storage and a power-to-gas project of an energy provider. The political, legal and economic framework conditions for the use and integration of energy storage systems were explored more deeply, while particular attention was given to their applicability in community energy supply systems.

Panel session

A line-up of prominent panelists discussed the integration of energy storage systems into future energy markets. podiumsdiskussion Prof. Uwe Leprich, spokesman of the Forschungsverbund Erneuerbare Energien (FVEE) clearly argued against cutting back power from wind farms because of bottlenecks in the grid. He argued instead for taking advantage of the power-to-gas technology in order to create heating fuels.

Prof. Dirk Uwe Sauer emphasized that even though to accommodate rising supplies of renewable energy, both technologies to store electrical energy and electric grids were needed, tapping the potential of alternative options for flexibility, such as Demand Side Management, must take priority over grid expansion and massive use of storage technologies. He argued, therefore, against overly hasty and large-scale incentive schemes for energy storage systems at this stage and in favor of creating framework conditions and markets, which would reward the full system benefit of energy storage.

Poster awards
posterpreisgewinner 2The IRES 2013 Scientific Steering Committee celebrated the authors of exceedingly outstanding posters in the main hall, which supports the dome of the Berlin Congress Center, as they had done in prior years. Konrad Meyer, David Kleinhans and Thomas Vogt, NEXT ENERGY • EWE-Forschungszentrum für Energietechnologien, came in first place with their poster "Potential of Power-To-Heat Technologies and Distributed Heat Storages for the Balancing of Electricity Grids".

1st place: „Potential of Power-To-Heat Technologies and Distributed Heat Storages for the Balancing of Electricity Grids"Konrad Meyer, David Kleinhans und Thomas Vogt Next Energy – EWE-Forschungszentrum für Energietechnologie e.V., Oldenburg

2nd place:"Optimal Deployment of Power-to-Gas Energy Storages in the Context of an 85% Renewable Energy Scenario"Mareike Jentsch Fraunhofer IWES, Kassel

3rd place:"Multi-Storage Hybrid System Approach and Experimental Investigations"Thilo Bocklisch, Martin Paulitschke, Michael Böttiger TU Chemnitz, Chemitz

Field trips
Two field trips to local operating energy storage sites rounded off IRES 2013. The Berlin-Adlershof based firm Younicos demonstrated the ability of commercial-scale batteries to successfully smooth out short-term fluctuations in the power grid. Using real power flows it proved the stable and safe operation of grids relying 100 % on renewable energy. On a rainy autumn day, participants in the second excursion visited Durion, the Berlin-based manufacturer of a LiFePO4 battery system (2 MW / 2.5 MWh). It stabilizes the electric frequency in the virtual power station of Vattenfall Wärme AG. Prof. Norbert Menke and his team were available to discuss selected scenarios of applications for differently sized energy storage systems.

The current edition of Solarzeitalter includes an interview with Professor Dirk Uwe Sauer of the RWTH Aachen University. The Scientific Conference Chairman of the IRES speaks about the significance of energy storage technology in the transformation of the energy system.
