no longer just giant batteries
If you need more evidence that the energy storage more than the lithium-ion batteries, take a look at the latest research projects smart grid utility storage.
U.S. Department of Energy Tuesday announced $ 620 million stimulus plan from 32 to the network chip will work with another $ 1 billion of private capital, plus funds. A 770 million VGP-BPS9/B, VGP-BPS9/S, VGP-BPS9A, VGP-BPS9A/B, vgp-bsp13/s from government sources, in the next few years, the industry's total energy storage, given the storage technology in a real-world experience, the number of doses.
is not in the list, the compression energy storage batteries and air circulation outstanding, two technologies are rarely discussed in a few years. In addition, combinations of flights and the use of battery energy storage in a distributed community.
It is unlikely that all funded by the U.S. Department of Energy projects will be immediately having been said. However, the store has clearly become a vision of the smart key factor in the network. Many start-up companies are developing the technology, they hope to make a pumped storage hydropower station, or damage to specific requirements, taking into account cheaper form of storage tools. In cooperation with the water pump, water pump up and released during peak hours to run a generator. But its use of geographical limitations.
16 grants authority to a number of wind energy storage, which is a variable source of energy storage of key sectors. In California, for example, utilities Pacific Gas and Electric Company plans to wind turbines store the energy generated at night when the wind turbine is the most productive underground caverns. During the day, when the increased demand for the grid, air release and transmission of electricity through a turbine.
In the compressed air in underground storage has the advantage that it can be inexpensive battery that can store multiple hours of energy value. On the PG & E's summary of Kern County, California, the project resulted in 10 hours 300 megawatts of electricity, enough to power tens of thousands of thousands of houses.
Another new technology uses compressed air storage, technology developed by a rotating, over Dartmouth College SustainX metal cans. The release of compressed air towholesale electronics run a hydraulic motor drives for electric power generators.
Flow batteries, while the use of liquid electrolyte solution tank. When the two liquids interact, there is a chemical reaction to produce electricity flow.
This approach has the advantage of a lot of storage capacity and discharge of energy relatively quickly, according to Save Electricity Association. A project will use high-quality electric power technology, so that the size of semi-trailer flow battery zinc remain at peak demand on the grid and supply a constant frequency.
Different winds
A variety of advanced technologies, energy storage applications. Beacon Power Flywheel winner, for example, can absorb and release the power of U.S. dollars, "MW to the grid, but only in 15-minute fire. However, the wheels be more careful, because they are a clean alternative to natural gas now used in order to rationalize the frequency of short-term fluctuations in the network of factories, the company said.
Large batteries, will also be further testing of the storage grid. Duke Energy plans to tap close to 20 million kilowatts of wind power supply Notrees power project in Texas, "the value of several types of batteries." Hybrid "system battery is designed for two tasks: to smooth short-term fluctuations in the network, and to provide value to the power during the day, based on the Duke Energy representative.
Utility Portland General Electric in the next two years, plans to install five batteries auto parts supplier Ener1 battery juice to provide sufficient power for about an hour 400. Substitute chemicals, including carbon battery lead Eastern Pennsylvania production will also be used.
A project will test the feasibility of vehicle batteries used to store the grid. Plug-in lithium-ion battery system of the A123 will be used for car storage projects in both the supply of 20 community battery for digital hours and 25 million kilowatts. After many years in the automotive performance of lithium-ion batteries to reduce, but there are enough storage and application of the power grid, utility management officials said.
