27ZENN to acquire 51% of EEStor

Zenn Motor Co. may have a name better associated with a sense of peace, but the company it has been connected to for years and has now agreed to buy does have a bit of uncertainty about it. Canada-based Zenn, which used to make and sell lead-acid battery-powered neighborhood-electric vehicles, has reached an agreement to buy a majority stake in energy-storage company and distribution partner EEStor.

9SolarCity using Tesla battery tech for DemandLogic grid energy storage

Grid energy storage is becoming a tangible business opportunity for cleantech companies and automakers these days – it's all that's left of Coda, for example, and Toyota is open to the opportunities. Sun-power provider SolarCity has entered the market with DemandLogic, a smart energy storage system designed to deal with what it calls two major pain points for businesses: rising utility demand charges and increasing grid outages. SolarCity is using Tesla Motors' advanced battery technology

5Coda Energy emerges as Coda Holdings bankruptcy finishes up

Coda Energy has been officially unveiled. As Coda Holdings, Inc., and its Coda Automotive electric carmaker subsidiary, has closed bankruptcy sale proceedings, the energy storage division is now ready for business.

AddCoda officially files for bankruptcy, shifts focus to energy storage

Anyone who had Coda Automotive in your office pool for the next electric vehicle maker to declare bankruptcy, go on and collect your winnings. Coda announced today it will restructure as an energy storage business after voluntarily filing Chapter 11 bankruptcy in the District of Delaware. The automaker said it expects the sale process to last 45 days.

29200,000 vehicle-to-grid plug-ins to be sold by 2020

Electric vehicles camped in parking spaces will be an ideal vehicle-to-grid energy source for buildings equipped with energy management systems. A new report from Navigant Research forecasts that nearly 200,000 plug-in electric vehicles equipped with vehicle-to-building (V2B) technology will be sold from 2012 through 2020.

AddToyota recycling old hybrid batteries into energy-storage systems for dealers

How's this for a "willing buyer"? Toyota is going to recycle nickel-metal hydride batteries from old hybrids into energy management systems and will then sell those systems to Toyota dealerships in Japan.

82Battery cost dropping below $200 per kWh soon, says Tesla's Elon Musk

During its recent fourth quarter 2011 financial results Q&A conference call, CEO Elon Musk had, of course, lots to say about Tesla Motors and its various products. One statement though, concerning the falling cost of batteries, spoke to the broader electric vehicle (EV) market and bears repeating. The high price of energy storage is, after all, one of the major barriers to lower EV prices and, consequently, faster consumer adoption.

12EV maker Coda Holdings launches energy-storage division

AddElectrovaya launches scalable lithium-ion energy storage system

Electrovaya, a developer of lithium-ion battery systems, has announced the launch of a product line targeted at solving the energy storage challenges that utilities are faced with today. Electrovaya's Lithium-Ion Battery Energy Storage System (LIBESS), a smart grid-capable unit, stores excess electrical energy that flows in during off-peak periods and then cranks out power during times of peak demand

AddSupercapacitor breakthrough beats batteries with graphene *UPDATE

In the coming decades, hybrids, and maybe even all-electric vehicles, may cruise without batteries. Instead, the energy in these vehicles of the future will be stored in a supercapacitor which could be recharged in minutes, possibly seconds. We've heard of the potential of supercaps (and ultracapacitors) before, but researchers have just announced they've overcome an obstacle to this device development. In the lab, they have developed supercaps with an energy density equivalent to that found in
