Project financing for six large-scale energy storage systems in Germany has been helped along by due diligence provided by testing, certification and knowledge services group TÜV SÜD.

The Cook Islands in the Pacific will host a 5.6MWh lithium-ion battery energy storage system for the integration of renewables, in a project funded by the Asian Development Bank, European Union and Global Environmental Fund.

A ‘hybrid’ plant for storing wind energy in batteries has been constructed by infrastructure and energy firm Acciona in Spain, thought to be the first such project in the country.

Energy storage in the US has just enjoyed its greatest quarter for megawatt-hours deployed, up almost 1000% from the equivalent period last year, installing 233.7MWh.

The US state of California’s Senate has approved a bill that would provide rebates to customers for the purchase of energy storage systems, bringing the legislation a step closer to introduction.

The key value propositions for commercial energy storage are based around “maximising economics subject to operating constraints”, according to Stem and other energy storage system integrators and operators.

Electrification of remote areas of the developing world using solar, storage and microgrids can and should go further than just providing basics like lamps and phone chargers.

Hybrid systems that combine high power technologies such as lithium-ion and long duration, high energy redox flow energy storage is “where the market will go”, the CEO of a vanadium ‘flow machine’ provider has said.

Even if the US withdraws from the Paris Agreement on climate change, economics and popular support for clean energy mean the industry will not lose its momentum, the chief commercial officer of Younicos has said.

Leaning on an existing track-record and manufacturing scale of electric vehicles (EVs) and their batteries remains an essential component to delivering cost-effective energy storage, BYD global sales director Julia Chen has said.
