November 19th - 21st, 2007, Bonn, World Conference Center

We cordially invite you to the Second International Renewable Energy Storage Conference (IRES II).

In about 40 presentations, IRES II will embrace the current status of energy storage technologies, as well as other new research and industry approaches to electricity and heat storage, alongside such integrated solutions eliminating or minimizing the need for additional storage.

The conference aims at demonstrating how a diverse mix of Renewable Energy sources can be handled to ensure the balance between demand and supply and also, how more efficient and autonomous energy supply systems can be established.

The EnergyAgency.NRW, EUROBAT and the Electricity Storage Association (ESA) are our partners at IRES II, as well as the European research cooperation for promoting heat storage, PREHEAT.

The IRES II addresses the research and development community in the fields of energy storage and grid management, suppliers of Renewable Energy products and services, Renewable Energy producers, energy planners, energy industry specialists, political institutions and decision makers.

Together, by providing economic, technological and political impulses, we can create fresh momentum to the development towards Renewable Energies.

IRES II will be held in parallel to the Second World Renewable Energy Assembly (WREA). This enables IRES II attendees to exchange thoughts and ideas with the WREA participants. We look forward to welcoming you at IRES II.

Proposals for poster presentations for IRES II can still be submitted!

For each poster presenter there will be a display board that can be equipped with two A0/ISO 216-sized posters (841 × 1189mm). The fee for poster presenters is 50% of the regular fee + 200 € for the poster presentation. Included in this fee is the admission to the conference for an accompanying person. There will be a separate poster session on the second day of  the conference where the presenter can discuss his project with the other conference attendees.
