General Information

Due to the development of a high-technology-society, power demand has been increasing year after year. A big problem under such an environment is the big difference of the electric demand between day and night, and also throughout the seasons. It is getting difficult to construct power stations and transmission facilities which cover peak power demands not only from the point of construction cost but also conservation of resources. If we succeed to reduce these fluctuations, we can contribute to efficient operation at power stations, decrease of operation cost, and conservation of resources.

Energy Poverty

It is an alarming fact that today - in the 21st century - there are still billions of people without access to electricity or clean cooking facilities. The ambitious goals that have been set to eradicate extreme poverty can never be fully realised without acknowledging and confronting this fact.

Today, there are 1.4 billion people around the world that lack access to electricity, some 85% of them in rural areas. 50% of family income in developing nations goes to non-renewable energy sources.

Energy Storage Market Potential

BES

Fig: Grid-Scale Energy Storage (billion $)

  • Lux Research – 113,5 b$ by 2017
  • Piper Jaffrey – 600 b$ market over 10-12 years (including EV storage)
  • Boston Consulting Group – 400 b$ market potential in 2020
  • EPRI/DOE – annual savings of 50 b$/ year via energy storage

Lack of Energy Storage Leads to Overbuilding and Underutilization

  • 25% of distribution and 10% of generation and transmission assets (worth hundreds of billions of $$) used less than 400 hours per year
  • 5% reduction in peak load would provide generation capacity saving of ~$3 billion per year in the US
