Today, SDG&E is showcasing the world's largest lithium-ion battery energy storage facility in partnership with AES Energy Storage, which will enhance regional energy reliability while maximizing renewable energy use. The 30 megawatt (MW) energy storage facility is capable of storing up to 120 megawatt hours of energy, the energy equivalent of serving 20,000 customers for four hours.
Last year, the California Public Utility Commission (CPUC) directed Southern California investor-owned electric utilities to fast-track additional energy storage options to enhance regional energy reliability. In response, SDG&E expedited ongoing negotiations and contracted with AES Energy Storage to build two projects for a total of 37.5 MW of lithium ion battery energy storage. In addition to the 30 MW facility built in Escondido, Calif., a smaller 7.5 MW installation was built in El Cajon. Full Press Release:
Michael Kanellos for Forbes: The optimism in the energy storage industry is based on soaring demand, rapid technological advances, expanding capacity and, for some, what will likely be a scary competitive environment.
First, the good news. Lithium ion battery packs over the last ten years have declined faster than the cost of solar, said John Carrington, CEO of Stem, which makes behind-the-meter storage systems for hotels and other commercial customers looking to shave peak power costs, during a hallway meeting at Finance West sponsored by the American Council of Renewable Energy this week.
Solar panels have declined by 50% or more in the last five years. Batteries have declined by 80% in three years, he said. Battery packs hit the under $300 per kilowatt hour mark last December, Carrington added. By 2020, battery pack prices could drop to $190 per kilowatt hour. (In 2007, lithium ion battery packs in the wholesale markets sold for around $1,000 per kilowatt hour.) Cont'd...
Elizabeth Woyke for MIT Technology Review: Lithium-ion batteries power everything from smartphones to electric vehicles. They’re well suited to the job because they are smaller and lighter, charge faster, and last longer than other batteries. But they are also complex and thus costly to make, which has stymied mass adoption of electric transportation and large-scale energy storage.
Yet-Ming Chiang thinks his startup 24M has the answer. The key is a semisolid electrode. In a conventional lithium--ion battery, many thin layers of electrodes are stacked or rolled together to produce a cell. “Lithium-ion batteries are the only product I know of besides baklava where you stack so many thin layers to build up volume,” says Chiang, who is a cofounder and chief scientist at 24M as well as a professor of materials science at MIT. “Our goal is to make a lithium-ion battery through the simplest process possible.” Cont'd...
Lithium Continues to Top Mining Sector as Companies Pour Funding into Mining Operations and Research & Product Development Advancements
Novel synthesis method developed at University of Eastern Finland opens up new possibilities for utilising Li-ion batteries
By Vlad Tverdohleb for CruxialCIO: Panasonic Corp is the producer of lithium-ion batteries for Tesla Motors Inc’s cars. However, Panasonic is now preparing to begin selling batteries that power homes in Europe. Its first market is Germany, where homeowners are even given greater incentives to switch to clean electricity generated by solar-power devices.
Thus, Panasonic’s push into international markets with home batteries is putting the Japanese company into direct competition with Tesla, its flagship customer. In May, the American company unveiled a suite of batteries to store electricity for businesses and homes.
Panasonic plans to move later to France, the U.K. and other European markets. Laurent Abadie, Panasonic Europe chief executive officer, declared on Wednesday, Sept. 2, in an interview at the IFA International Consumer Electronics Show in Berlin, that the company has not decided yet when it would start sales in Europe.
