grid storage

Eos Energy Storage is developing a zinc air battery it claims will be able to clear up bottlenecks on the power grid by placing them at office buildings and shopping malls.

The energy storage startup before the end of March plans to close a round of funding from corporate partners which is expected to be at least $5.5 million. It plans to raise $20 million by the end of this year and start making its batteries at a pilot manufacturing facility next year, said President Steve Hellman.

Although it doesn't have a product on the market yet, Eos … Read more

Speedy lithium ion batteries, the power source for consumer electronics and electric vehicles, are making inroads into the renewable energy business.

A123 Systems today announced that a Hawaiian wind project developer will use its batteries to firm up power delivery into the grid. The Auwahi Wind project, which has a generating capacity of 21 megawatts, will be buttressed by a giant battery bank able to deliver 11 megawatts of power.

It's the second time this year that A123 Systems' storage systems, built around shipping container-size battery banks, were chosen to be co-located with a wind farm. The Laurel Mountain … Read more

By storing solar energy in molten salt, BrightSource Energy can now build one less solar power plant.

The company said today that it is adding energy storage to three planned solar projects that will supply power to utility Southern California Edison.

Instead of building seven power plants to provide about 4 million megawatt-hours per year, BrightSource now expects to be able to meet that with six concentrating solar plants to be built over the next six years, including three that will have storage. It is now constructing its first project, the Ivanpah Solar Electric Generating System, which will not have … Read more

While consumers may simply crave longer-lasting batteries for electronic gadgets, the holy grail for many material scientists is batteries that can pump power into the grid for hours.

Stanford University researchers today detailed a new electrode material they claim holds promise for grid storage batteries that can work 30 years without a dramatic decline in performance.

In the lab, the copper and iron-based nano-engineered material was able to take 40,000 charge/discharge cycles while still maintaining an 80 percent capacity. By contrast, the lithium ion batteries used in consumer electronics degrade noticeably after only a few hundred cycles.

The … Read more

Liquid Metal Battery, a company formed to make cheap storage for wind and solar power, has hired its first CEO.

Phil Giudice, who was the third employee of demand-response company EnerNoc and the Massachusetts Department of Energy Resources Commissioner until earlier the year, announced his "new gig" on Twitter. One of his tasks as CEO is to raise more money to build up the company, he told The Boston Globe.

Liquid Metal Battery was spun out of the lab of Donald Sadoway, a professor of materials chemistry at the Massachusetts Institute of Technology. Funding for the company has … Read more

A huge battery bank connected to a wind farm was officially commissioned today in a project that makes wind power more closely resemble a traditional power plant.

Two divisions of energy project developer AES today said that the 98-megawatt Laurel Mountain wind facility in West Virginia is now connected to 32 megawatts worth of lithium ion batteries from A123 Systems. It's the largest project to couple wind power with lithium ion batteries, according to the company.

The shipping container-size batteries will allow AES to gradually adjust power delivery to the grid up and down, rather than have a more … Read more

Rather than cranking up a generator during a blackout, Nissan Leaf drivers may be able to tap into the electric car's batteries.

Nissan earlier this week unveiled its Nissan Leaf to Home system, which it plans to commercialize in Japan within a year.

The system uses the Leaf charging station to draw from the car's lithium ion batteries and feed current into a home's electricity distribution panel. The 24 kilowatt-hours of energy storage in the Leaf is enough to power an average Japanese home, which uses about half the energy of an average U.S. household, for … Read more

BrightSource Energy today announced molten salt energy storage for its heat-driven solar power plants, touting the advantages over flat solar photovoltaic panels.

With the storage, BrightSource solar power plants can deliver electricity to the grid consistently and into the evening hours. That makes the solar power more valuable because utilities pay more for power during peak hours, which continues past nightfall.

BrightSource's solar tower technology generates steam from a field of mirrors called heliostats shining onto a tower. The steam is fed into a conventional turbine to generate electricity. After turning the turbine, the steam is condensed into water … Read more

Lithium ion battery maker A123 Systems today said it will supply an energy storage system attached to a wind turbine in a test that could lead to further grid business in China.

Power equipment manufacturer Dongfang Electric will install a 500-kilowatt battery bank attached to a 1.5-megawatt wind turbine and diesel generator to evaluate how well the batteries can smooth out dips in power production from wind. The system, which can store 125 kilowatt-hours, is scheduled to be installed by the end of the year.

Wind power has boomed in China over the past few years, driven by government … Read more
