Advanced Rail Energy Storage (ARES), is a Santa Barbara, California based company, providing a deployable solution for grid-scale energy storage. ARES mission is to enable the electric grid to integrate unprecedented amounts of clean, environmentally responsible, renewable energy while maintaining the reliable electric service necessary to power growth and prosperity. Since it's founding in February 2010, ARES has developed and filed both domestic and international patents for an advanced method of utility-scale electrical storage. ARES facilities are designed to: provide grid security and reliability; support the increased use of renewable technologies, and to provide an energy storage solution that does not rely on water.

An Important, and Sometimes Overlooked, Energy Efficiency Tool | Energy Economics Exchange - 1 views
Solar panels capture energy from light and convert it to electricity. This is the most visible form of energy harvesting, but it is hardly the only one. Energy harvesting captures energy lost as heat, light, sound, vibration, or movement. Devices that harvest or scavenge energy can capture, accumulate, store, condition, and manage this energy into electricity for consumption. That’s important, because our existing electricity infrastructure is extremely wasteful in its use of energy. For instance, today’s technologies used in electricity generation are not energy efficient. Traditional gas or steam-powered turbines convert heat to mechanical energy, which is then converted to electricity. Up to two thirds of that energy input is lost as heat. Those old incandescent bulbs (technology invented by Thomas Edison in 1879) were real energy losers too. Ninety percent of the electricity flowing into incandescent bulbs ends up as waste heat. That’s lost energy, which is why smart federal legislation banned incandescents in favor of more energy efficient sources of lighting starting in 2012.
Clever MIT floating wind turbines can store power for when the wind doesn't blow : Tree... - 0 views
A single 25-meter sphere at a depth of 400 meters could store up to 6 megawatt-hours of power, so a large offshore wind farm with hundreds or even thousands of those could become a giant on-demand battery, potentially producing as much power as large power plants (it all depends on how far you scale up the idea). These anchor/storage spheres could be built on land and then brought out to sea. No need for too much super-expensive deep sea construction.
Preliminary estimates indicate that one such sphere could be built and deployed at a cost of about $12 million, Hodder says, with costs gradually coming down with experience. This could yield an estimated storage cost of about 6 cents per kilowatt-hour — a level considered viable by the utility industry.
There’s a promising new entry in the race to build cheap batteries for storing energy from solar panels and wind turbines. Stanford researchers led by Yi Cui, a professor of materials science and engineering, have demonstrated a partially liquid battery made of inexpensive lithium and sulfur. Cui says the battery will be easy to make and will last for thousands of charging cycles.
Cui believes that the material and manufacturing costs of the battery might be low enough to meet the Department of Energy’s goal of $100 per kilowatt-hour of storage capacity, which the DOE estimates will make the technology economically attractive to utilities. Existing batteries can cost hundreds of dollars per kilowatt-hour of capacity, although several companies are working to commercialize cheaper ones (see “Ambri’s Better Battery” and “Battery to Take On Diesel and Natural Gas”).
After premiering its 2.5-megawatt, 120-meter rotor Brilliant wind turbine in February, GE is now announcing the commercial installation of the first three models that will integrate energy storage capability.
Perhaps Thomas Edison was right after all. As new technology develops, it's time to ask the question: should be using direct current (DC) instead of alternating current (AC) power?
