Executive Summary 

Meeting Scope

The IEA’s Experts Group on Energy R&D and Priority Setting will host a workshop on 22–23 October 2014 in Berlin, Germany, hosted by the Ministry of Economic Affairs and Energy. This workshop will focus on the evolving nature of the grid, with the goal of identifying novel approaches, RD&D needs, other areas not well covered but needing attention, and innovative case studies related to electricity storage in a flexible electricity grid of the future. The workshop will address a broad range of topics concerned with innovation and R&D strategies for energy storage and electricity grid enhancement with a focus on how best to welcome the inclusion of variable energy sources.

With input from speakers representing various actors, sectors, and regions, the workshop will result in a summary report, posted publicly, that identifies challenges concerning energy storage and energy grids, highlights a broad sampling of activities underway in various countries and technology sectors, identifies priorities and gaps in current programs for RD&D planners, and suggests a number of areas in the innovation arena needing public policy attention.

Target Audience

In addition to EGRD national experts, we are seeking input from RD&D decision-makers, strategic planners, and program managers from industry concerned with energy storage systems technologies related to electrical grids. Participation is by invitation only.
