19 Mar 2014: IEA's Energy Storage Technology Roadmap

The International Energy Agency's (IEA) energy storage technology roadmap aims to increase understanding among a range of stakeholders of the applications that electricity and thermal energy storage technologies can be used for at different locations in the energy system. Emphasis is placed on storage technologies that are connected to a larger energy system (e.g. electricity grid), while a smaller portion of the discussion focuses on off-grid storage applications. This focus is complemented by a discussion of the existing technology, policy, and economic barriers that hinder energy storage deployment. Specific actions that can be taken to remove these obstacles are identified for key energy system stakeholder groups.

11 Nov 2013: European Energy Storage Mapping

This report presents the very first overview of research, development and demonstration projects on energy storage in Europe. A total of 14 countries are covered, together with activities sponsored directly by the European Commission. This mapping provides an overview by looking into the technological orientation of each project and by mapping at which level it is related to the electricity grid (from generation of transmission to distribution and end users). This will inform further decisions on the role of storage in grid development and the interactions between both.

14 Oct 2013: Assessing Storage Value in Electricity Markets

This report summarises the results of joint EDF R&D / JRC-IET research effort on energy storage. It provides a summary review of current literature on energy storage with particular attention to three broad topics: (i) the methodologies used for assessing storage value as defined by the fundamental assumptions, the problem definition and the solving strategies, (ii) the current market environment for electricity storage including drivers and barriers to deployment, the impact of technology developments, and (iii) the range of possible regulatory environments which would address the current challenges of power storage.

1 Jul 2013: EASE input to the Methodology Defining a Cost-Benefit-Analysis for Energy Storage

ENTSO-E has asked EASE to provide insights on a CBA for storage projects in order to be able to integrate storage projects next to transmission projects in the CBA of the TYNDP. The focus of this document is on energy storage projects that are reaching the threshold size of 225 MW. Any electricity storage connected at the distribution level and medium-sized electricity storage connected at the transmission level is thus excluded from the scope of this document.

3 May 2013: Assessment of the European Potential for Pumped Hydropower Energy Storage

This JRC report presents the results of the assessment for pumped hydro energy storage in Europe under certain topologies and scenarios. The results show that the theoretical potential in Europe is significant. A comparison with the existing pumped hydro energy storage facilities reported in 14 countries suggests that the Topology 1 theoretical potential is 3.5 times the existing capacity whereas the Topology 2 realisable potential is 10 times as much the existing capacity.

30 Jun 2012: Role and Value of Energy Storage Systems in the UK

A comprehensive whole systems analysis approach is developed in this study to establish the role and quantify the value of electricity storage, alongside alternative technologies, in facilitating cost-effective evolution to a low-carbon future. In this context the key objective of this work was to model and analyse the value of grid-scale storage in the future GB electricity systems (based on DECC Pathways), with the outputs intended to inform the UK energy policy.

20 Jun 2012: Electricity Storage: How to Facilitate its Deployment and Operation in the EU

This report, developed by the THINK! project, analyses whether the benefits that electricity storage can provide are already recognised and valorised by the existing market design and regulation.

31 Jan 2012: European Renewable Energy Network

This document was requested by the European Parliament's Committee on Industry, Research and Energy (ITRE) and aims to identify the energy network infrastructures needed to cope with the increasing share of renewable energies. The analysis covers a timeframe up to 2050 taking into account different existing projections of renewable energy development. Published infrastructure development priorities as well as methodologies including notably infrastructure cost benefit analyses are critically assessed. It furthermore analyses the relationship between the promotion of renewable energy generation and related infrastructure on the one hand, and other (energy) policy goals and existing legislation at EU level on the other. Obstacles to grid-roll out are identified and policy recommendations are proposed.

31 Jan 2012: Lessons from Iowa: Development of a 270 MW Compressed Air Energy Storage Project

This report prepared by Sandia National Laboratories summarises the due diligence lessons learned in development of the Iowa Stored Energy Park, a 270 Megawatt and $400 million compressed air energy storage (CAES) project that, after eight years in development, was terminated because of site geological limitations. The purpose of the report is to enable these lessons to assist other storage projects in their development.

31 Dec 2011: Harnessing Variable Renewables: A Guide to the Balancing Challenge

Written for decision makers, this guide sheds light on managing power systems with large shares of variable renewables. It presents a new, step-by-step approach developed by the IEA to assess the flexibility of power systems, which identifies the already present resources that could help meet the twin challenges of variability and uncertainty.
