Energy storage systems in the U.S. – additional information
Energy storage installations in the U.S. are expected to reach a capacity of 3.7 gigawatt hours by 2020. There are systems which are currently operating or under development in every U.S. state and can range in size from small batteries to large systems that are in place in major reservoirs and pumping facilities. The benefits of energy storage can include reduced or avoided costs and additional revenue generated by the storage owner or operator. Energy storage can also be essential in times of emergency, such as during power outages, equipment failures, and accidents.
Energy storage technologies have become more commonplace in many industries and their usefulness has been noted by companies around the world. In the United States, there are hundreds of companies building commercial systems across the country. Vionx Energy, one of the market leaders, received 58.1 million U.S. dollars in venture capital funding in 2015. The company is based in Massachusetts and is primarily focused on providing solutions for modern electricity grids.
There are a wide range of energy storage technologies and each solution tends to have a wide reach into various industries. For example, the lithium-ion battery is used to power a wide range of products, from small portable devices such as mobile phones and laptops, to power tools like cordless drills and hedge trimmers, to electric vehicles like electric cars and aircrafts. It is expected that energy storage demand from electric vehicles will reach 18 terawatt hours by 2020. The cost of lithium-ion batteries ranges from 1,085 to 4,100 U.S. dollars per kilowatt .
