energy storage: costly but key to power production - energy storage companies

Have you ever thought that you can put up those beautiful sunny and energetic days?
Well, some companies are trying to do this--
In the context of "energy storage.
"Simply put, this is a technology that allows batteries or other devices to use the wind and the sun when they are sufficient to release energy when they are not.
This will undoubtedly help green energy to make progress in the market and overcome their arguments that are too unreliable.
However, energy storage has other assets: If proven effective and cost-effective, it will enable utilities to avoid investment in power plants and transmission and distribution.
This will also allow the generators to operate more efficiently, as they operate closer to full load over a longer period of time.
In an interview with the writer, Chris Shelton, president of AES Energy Storage, said: "Our grid storage products are commercial because they release the value of existing customer assets . ".
He added that for utilities, this means that existing transmission and power generation are more efficient and do not require the construction of certain power plants that will only be used when energy demand reaches its highest, note that they can also improve the performance of wind installations.
In the case of AES, an independent power producer, it owns such storage assets and provides them through contracts.
Overall, it has an energy storage capacity of nearly 500 MW.
Semester development.
For example, it developed a 12 MW project in Chile, which was put into use in 2009.
The battery storage system AES has optimized the traditional fossil fuel generator and must be kept in reserve.
The battery helps meet these requirements and back up unforeseen failures on the electrical network-
120 times have occurred since 2009.
Meanwhile, AES deployed 32-last fall-
Megawatt storage project as part of the West Virginia wind farm.
In fact, this battery will have a short circuit.
This term causes vibration in the system.
In other words, it is not using energy all night, releasing energy during the day;
Instead, it maintains power for a short period of time, and then lets it burst out when the wind speed changes to smooth power production.
However, most people believe that energy storage is still too expensive and too untested.
But some power suppliers say the tools could go mainstream with a little help from the federal government.
According to the Electric Power Research Institute, in order to seize greater market opportunities, the prices of these systems installed must drop sharply.
Depending on the required storage time, the cost may be three times the cost of the business.
"High cost performance --
"Scale energy storage will revolutionize the way we invest and manage our power systems," said Bob Bellemare, chief operating officer at UtiliPoint International . ".
"Today, due to the low cost and efficiency of mass storage, producing electricity is usually cheaper than storing it for later use.
"What does it take to get there?
The electricity storage association is advocating tax and fiscal incentives, such as investment or production tax credits for wind and solar energy, which may not be updated after this year.
It also wants to see energy storage included in the Obama administration's clean energy standards, as well as the renewable energy portfolio standards now set at the state level.
In addition to the $0. 185 billion offered to 16 sep arate storage projects through the 2009 stimulus program, all of this will be the most important.
For Uncle Sam, funding research and development is one thing.
Some argue that investing billions of dollars into companies that have not yet proven the commercial value of their energy storage technologies is another matter.
Brad Roberts, executive director of the Storage Association, retorted: "The next five years will be crucial and provide a huge opportunity to fully commercialize storage technology . ".
It is clear that there are multiple forms of storage devices: the most popular today is the batteries connected to the transmission grid, where they will suck out the electricity at night and store it.
Then send during the day when prices rise.
Then fast.
Response flywheel, and a deviation called kinetic energy storage, which is practical in a very short period of timeterm needs.
In addition to these tools, there is a compressed air energy storage device that stores air underground and releases it in the form of heating to generate electricity.
There is also mature pumped storage, the turbine pushes the water into the reservoir at night, and then lets it leave during the day with the highest demand.
Young products are now relatively expensive and how they operate in a business environment remains unknown.
Experts say they must be able to provide other services if they are to be cost-effective.
Until then, the federal government will work with private enterprises to help promote the development of the industry.
Duke Energy, for example, is installing batteries at a wind farm in Texas. That is a 36-
Megawatt capacity system. The U. S.
When utilities pay the same amount, DOE is putting in $22 million.
Duke has publicly stated that such a grid
Most believe that connected energy storage will become economically viable by 2015.
Nevertheless, as the amount of investment increases ---
Especially in cars, they want to grab the market from gasoline.
Electric car--
The cost will fall.
Supporters say these advances will cross the border, allowing storage on the transmission grid to meet more needs, such as peak demand.

In an interview with President Mitch Pulwer, the technology is now in effect.
But he added that the advanced battery industry needs government assistance to increase production and build a supply chain, all of which will help reduce the price of batteries-
This tool also provides powerful applications for the utilities industry.
"The challenge for the grid is uneven load," Gary larcliffe, vice president of Smart Grid North America at ABB, added in a conversation with reporters.
"Energy storage balances these needs and addresses the issue of variability.
The power network then becomes more reliable and efficient, which may eliminate the need to expand electricity production.
At the same time, developers of wind and solar energy will getneeded bonus --
When they don't have one, a buff hit. It’s coming.
However, improvements in price and efficiency will be a clear feature.
