Under construction by Australian utility AGL, the 250 MW/250 MWh battery is the largest planned grid-forming battery in the world.

Scientists in the United States pieced together data from hundreds of different sources, looking to establish the key factors that have led to consistently falling prices for lithium-ion technology since their commercialization thirty years ago. They find that public-funded research, primarily in chemistry and materials science, has made the largest contribution to cost reduction. And they offer suggestions on policy and investment to ensure that the research can continue to make these important contributions to reduction in battery costs.

English manufacturer Aceleron claims every component of its devices can be accessed for replacement, repair or recycling, with the business’ co-founder stating the aim is to ensure ‘100% of the materials in our batteries will continue to be used for as long as possible – preferably forever.’

Developed by a spin-off of Dutch research institute TNO, the battery is claimed to offer higher energy density, longer lifespan and increased safety compared to conventional lithium-ion batteries. It will initially be applied in wearables and electric cars.

Panasonic said the system is available in the U.S. with storage capacities of 17.1 kWh and 25.65 kWh. The product comes with a floor-standing battery cabinet and a hybrid smart inverter with 4 MPPTs.

The Netherlands storage industry association and the Dutch grid operators have proposed a faster phasing out of the net metering scheme to enable wider adoption of batteries among PV system owners. A 30% rebate on the purchase and installation of residential storage systems could help achieve the plan.

BloombergNEF says falling battery costs and “surging” renewables penetration make energy storage a “compelling flexible resource in many power systems.”

The Chinese manufacturer says the battery has a depth of discharge of 95%. It will be available for sale starting from Q1 2022.

The battery was fabricated by Chinese scientists with a low-cost electrolyte made of a derivative of TEMPO, which is a well-known electroactive aminoxyl radical used with several applications in chemistry and biochemistry. According to the researchers, the battery shows high redox potential and is crossover-free.

The town of Marble Bar in Western Australia’s remote East Pilbara region is famed for at one time recording 100 consecutive days of temperatures exceeding 37 C. So it’s no wonder the town’s residents have excess solar and nowhere to put it. That is, until now, thanks to the installation of a battery energy storage system beside the town’s centralized solar farm.
