Dallas, TX (PRWEB) September 15, 2012
This is increasingly presenting a major problem to power suppliers around the world as electrical energy infrastructures in most countries are antiquated, wasteful, and unable to cope with rising demand.
Features and benefits
- Analyze existing electrical energy storage technology.
- Examine existing smart grid projects and the storage solutions they have employed.
- Analyze the renewable energy sector and the issues associated with integrating green power into existing distribution systems.
- Assess the problems that can occur when suppliers face unexpected peak demand.
- Understand the major drivers behind growing global demand for electrical power.
- The problem of the intermittent delivery patterns of green energy technology can be solved by storing up power generated during off-peak periods for dispersal at times of greater need. However, the best means of storing energy remains a matter for debate with no definitive one-size-fits-all solution yet established as an industry standard.
- The European utility-scale battery market was valued at $126.4m in terms of revenue in 2010 and could be worth as much as $564.9m by 2015. With renewable energy investment increasing rapidly, the demand for battery storage is expected to rise as well.
- Along with compressed air energy storage, pumped storage offers the least expensive form of energy storage, with a 1,000MW project costing about $1,500/KW to $2,500/KW, according to the National Hydropower Association in Washington, DC.
