Stronger, More Cost-Effective Flywheels for Grid Storage

Beacon Power, a major player in flywheel energy storage, is now working with U.S. Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) on the development of a next-generation of flywheel storage. The new flywheel storage system is expected to canada viagra prescription be able to store 4 times as much energy as present flywheels, and at one-eighth the per kilowatt-hour cost.

This could lead to more capable power storage systems that could more readily be used with renewable power production such as wind and where to purchase levitra solar. According to Beacon Power, "One new application of particular interest to the Department of Energy is so-called "ramping" support for wind and solar power. The goal would be to provide one hour of flywheel storage as an energy-balancing resource for intermittent renewable energy assets, and thereby reduce the amount of canada pharmacy chewable viagra fossil-based backup power that might be used to provide the visit our site rx online levitra same effect. The benefit would be to enable significantly greater market penetration of renewable generation resources in a clean and sustainable way."

Flywheel energy storage is a technology that has been seeing advances and developments in its use for grid storage over the past few years. Recent projects have been installed in New York and in New England in the past couple years, and more are being explored for other parts of the country. Developments in grid storage like this can lead to reductions in the need to buy viagra us run expensive peak power plants in periods of high demand and can help facilitate the use of more renewably generated power on viagra uk chemist the grid.

Improved Storage for Solar Thermal Power Plants

Another big grant recipient from the six seriously geeky developments that received USDOE funding as part of the ARPA-E program is a program to develop thermal energy storage with supercritical fluids from the University of California Los Angeles (UCLA).

We've noted that the State of California has started approving solar-thermal power plants, and Google is even involved in research for solar-thermal power; it is a technology that has languished for some years, but is now starting to gain wider notice and application.

Presently, solar thermal power plants use a two-tank molten salt method for energy storage. Developing a supercritical fluid thermal storage system promises increased power storage and lower cost for solar thermal power plants. The proposed system is expected to have twice the energy storage density of current two-tank molten salt systems and viagra online generic cost less than 70% of what current systems cost.


A123 Opens Largest Battery Plant in North America

A123 Systems has opened a new lithium-ion battery plant in Livonia, Michigan.  Based on capacity, it's the largest battery plant in North America.

The new plant is 291,000 square feet and is designed to house the entire production process from R&D to manufacture of individual components and all the way through final assembly of battery packs. The facility will increase the company's production by 600 MWh per year, making its overall cell assembly capacity reach 760 MWh a year by 2011.

The company received a $249 million grant from the DOE as part of its program to drive innovation in battery technology.  It also received $125 million in incentives from the state of Michigan as part of a job creation program.  With that funding behind them, the company will be opening more facilities to ramp up production, including a coating plant in Romulus, Michigan that will be completed early next year.

Philadelphia Subway Feeding Braking Energy to Grid

When a subway train pulls into a station, it produces two things:  a loud screeching sound and lots of kinetic energy.  The Philadelphia subway is putting that second thing to good use by capturing the kinetic energy produced when trains put on the brakes.

A 1.5-MW regenerative braking system will be installed along the Market-Frankford line, which has the highest ridership in the city.  A huge battery will capture the purchase of indian fda levitra kinetic energy that will then be used by trains accelerating out of the stations, stored for future use or fed to cialis free pills the grid.  The Southeast Pennsylvania Transportation Authority will have the option to either use the power produced or sell it to the local utility.

The trains already use regenerative braking on a smaller scale but half of the energy is lost as heat.  This pilot program is aiming to dramatically increase the power captured.

The project should be completed by next spring and could save the transit authority $500,000 in energy costs.  If all Philadelphia stations were outfitted with the system, energy consumption could be cut by 40 percent.

Senate Legislation Proposes $1.5 Billion for Energy Storage Tax Credits


Three U.S. senators have introduced a bill to promote electric grid energy storage projects. The Storage Technology of Renewable and Green Energy Act of 2010 ("STORAGE 2010 Act") would provide tax credits worth as much as $1.5 billion for grid storage projects.

In addition to providing credits for utility scale projects, the bill also has provisions for businesses and homeowners who want to have on-site energy storage, whether or not they also have on-site renewable energy generation of their own. Grid scale projects could qualify for a 20% tax credit of up to $30 million, and individual projects could qualify for a 30% tax credit of up to $1 million.

Projects would be selected by the Energy Secretary based on their commercial viability and approved cialis pharmacy would look to those that "provide the greatest increase of reliability or economic benefit, that enable the greatest improvement in integration of renewable energy resources with the grid, or that enable the greatest increase in efficiency in grid operation."

Encouraging increased grid storage capacity is meant to help further the cheapest viagra adoption of intermittent renewable energy sources such as wind and solar power. Grid storage should also help in furthering a more reliable smart grid for national energy distribution.
