Energy storage is already competitive in a number of mainly grid-based applications, while lithium-ion battery prices could fall by as much as 50% in the next five years, financial advisory and asset management firm Lazard has found.

Steag, a major power generator which constructs, plans and operates power plants, is spending US$100 million on acquiring 90MW of large-scale energy storage to help stabilise Germany’s grid.

The number of installed stationary battery energy storage systems (BESS) is growing significantly. According to recent estimates, today’s annual global market volume of about US$1 billion is expected to increase more than twentyfold in less than 10 years, reaching a staggering US$20–25billion by 2024. Florian Mayr of Apricum Consulting looks at this growth in the context of specific use cases for storage in two of its most advanced regional markets, the US and Germany.

The UK’s Institution of Civil Engineers (ICE) has publishing a report which looks at how unlocking the potential of electricity storage through regulatory changes would support the transition to a secure and affordable low carbon economy, adding to a chorus of recent voices on similar topics coming from Britain.

In contrast to “behind-the-meter” household energy storage systems, whose operational strategy is generally aimed at local financial optimisation of power consumption, the use cases for battery technologies on an industrial scale are primarily determined by the requirements of the electricity supply grids, particularly the regional distribution grids. SMA’s Voker Wachenfeld and Dr Alexsandra Sasa Bukvic-Schaefer take a closer look at some of the demands and applications driving the sector forward.

US commercial energy storage provider Stem has deployed its first system in Hawaii, for a pilot project that could help the island state’s main utility reach renewable energy goals “better, and at lower cost”.

Energy storage will be used to maximise the benefit of locally generated solar power, including reducing transmission losses, in a trial put together in Bavaria, Germany, by a partnership between academics, private companies and local government.

While some observers have breathlessly called 2015 the “Year of the Battery,” a more accurate description might be that we are seeing the dawn of the “Age of Energy Storage,” especially the winning combination of storage integrated with solar and emerging smart grid technologies, writes Panasonic’s Daniel Roca.

One UK energy storage company has compared its latest venture to the energy trading markets of California ISO, as it prepares to pay its customers for providing vital grid services through their residential systems.

24M Technologies, a battery company spun out of A123 Systems in 2010, has signed a memorandum of understanding (MoU) to supply its semisolid lithium-ion cells to NEC Energy Solutions for use in NEC ES’s integrated energy storage systems.
