Electrical Energy Storage: Technologies, Applications and Markets

Electrical energy storage has remarkable diversity. Almost 200GW is now installed in stationary applications: some require short bursts of power for milliseconds or minutes; others call for substantial amounts of energy, delivered over a period of hours or days. Much larger opportunities await the development of novel storage technologies, to meet requirements associated with:

• the effective production and delivery of electric power
• the provision of secure, high-quality power at end-user sites
• support of renewable and distributed energy resources
• enabling technologies within the transportation sector.

These opportunities are now capturing the imaginations of a wide range of developers, potential users and investors.

Dozens of largely unproven technologies are vying for a stake in a market with tantalizing prospects but many uncertainties. Decisions that will influence this sector are hampered by a lack of reliable, unbiased information. EscoVale has an unrivalled track record in meeting this need, preparing independent analyses of emerging technologies for many hundreds of clients in six continents.

The study described here is concerned with high-energy storage solutions (typically capable of delivering nominal rated power for an hour or more). Coverage starts at single-digit kW ratings and extends to the highest levels. This includes GW supply industry applications, but the emphasis is on technologies appropriate for distributed energy markets (where systems rated at MWs and 10s of MW will continue to be seen as large projects) and transportation.

Clients will receive:

• report #5061 (2005, together with a mid-2006 update), quantifying high-energy storage markets, with forecasts to 2025 and a longer-term projection to 2050. Within this wider market analysis, there is focus on the various types of flow / redox battery – regarded as serious contenders for leadership in certain sectors, and with a forecast share of the overall accessible market approaching 10% by 2025
• a four-day consultancy allocation, to ensure that each client gets full benefit from the project resources and
• report #5161 (late 2006 or early 2007), refining the market analysis, and expanding the technical scope to include additional high energy:power ratio storage technologies
