The global energy transition driving the phasing out of fossil fuels and nuclear power and the turn towards decentralized renewable energy systems requires energy storage technologies. They play a dynamic and growing role when integrated in a system relevant manner and used cost-efficiently. They strengthen the local and regional use of renewable energy, can replace grid extension and support the necessary sector coupling. The crucial relevance intensifies the need for efficient framework conditions as well as to enable a technology, policy and market understanding of these standalone storage technologies.
The International Renewable Energy Storage conference (IRES) is the world's premier peer reviewed platform for energy storage policy, technology, networks, management and interactive prosumer models, business applications, smart grid integration and stabilisation applications. Over the course of three days more than 200 presenters explored how effective and cost efficient energy storage system can be applied not only to compensate for supply variability in renewable energy but to drive the revolution towards 100% renewable based sector coupling and energy trading systems. In the past 13 years, the IRES conference has gained a reputation for presenting all forms of storage technology: batteries, thermal energy storage and power-to-gas were presented just as much as small-scale and large-scale solutions for home storage and industrial heating. Offering insight into the technological development and presenting current framework conditions for the successful use of storage solutions the conference guarantees a broad pictures of this technology.
The IRES series was started by EUROSOLAR and the World Council for Renewable Energy (WCRE) in 2006. Over these past years it has emerged as the central platform for sharing knowledge and exchanging ideas on a key issue of future energy supply. The highly interdisciplinary event is an international gathering of all relevant stakeholders: leaders from the energy storage industries, renewable and conventional energy businesses, grid operators and utilities, from the hybrid and electric vehicle sector, as well as the building trades, science, associations, politics and the financial industry.
Users, investors, industrialists, researchers and stakeholders met in Düsseldorf, 12-15 March 2019, to present and discuss the newest research on energy storage, its (international) potential and outstanding examples of success. More than 80 presentations from international researchers were held over the course of the two conference days. In The IRES poster exhibition featured 80 presentations from research institutions, universities and companies. EUROSOLAR thanks all authors who contributed to the outstanding program and the high scientific level of the conference.
This special issue of Atlantis Press reliably presents the very best of IRES entries, and a collective, high-resolution snapshot of a dynamic field of emergent storage disciplines. EUROSOLAR expresses its sincere gratitude to all supporters: contributors, researchers, our conference participants and especially our exceptional Scientific Committee: without the input and participation neither the conference nor the publication of this special issue would have been possible.
