Bosch, BMW and Swedish state-owned power company Vattenfall have begun the latest attempt to harness the potential of batteries used in electric vehicles (EVs) to provide stability to electrical grid infrastructure.

Chilean authorities have received plans for an ambitious 600MW PV plant project which could be connected to a 300MW pumped hydro energy storage plant, from developer Valhalla Energy.

Energy security is a growing concern for economies across the world with electricity outages currently costing economies billions of dollars annually, driving electricity prices up. The US experienced nearly 700 power outages caused by severe weather between 2003 and 2012, costing the country up to US$70 billion annually.

The failure of a grid-connected storage system at a solar farm in Hawaii is part of the learning process the US island state is undergoing to integrate more PV using storage, according to analyst Dean Frankel at Lux Research.

A UK auction held to provide the nation with energy security, has failed to deliver the boost to energy storage that a top government minister had hinted would be the case, according to a number of commentators and industry figures.

Will the Indian battery market scenario witness a major change? As the power supply in the country continues to be unreliable, the role of batteries has to change from being an emergency back-up solution to a long time power/energy storage solution.

Two recent reports, one from credit rating and investment advisory agency Moody’s, the other from technology and tech market analysts Navigant Research, appear to show divergent views on the potential of distributed energy storage, including residential solar-plus-batteries.

Grid storage and distributed energy technologies overseen by the Advanced Research Projects Agency – Energy (ARPA-E) in the US will be accredited by technical advisory service DNV GL for the next four years.

Just 3–4% of electricity generated by utilities globally is stored today, according to the International Energy Agency. This is despite the fact that storage can help overcome the energy ‘trilemma’ of curbing rising energy prices, the need to ensure the security of supply and creating a low carbon economy. So, what’s the hold-up? Taking the UK as his starting point but with lessons transferrable to other regions, Roger Lin of NEC Energy Solutions explains and counters some of the myths that stand in its way.

A 1MWh battery developed by US manufacturer Aquion Energy and installed at a private estate in Hawaii will allow the area’s residents to meet almost all of their electricity demand with power generated from a connected solar array.
