Energy storage

Trading firm Marubeni has secured the exclusive distribution rights to EnerG2’s carbon materials for energy storage devices in Asia.

EnerG2’s carbon materials are used for rechargeable lead-acid batteries, electric double layer capacitors (EDLCs or ultracapacitors) and lithium-ion batteries. A developed carbon technology platform enables the company to design and manufacture customised carbon and silicon-carbon nano-composite materials.

German BASF and US energy storage start-up EnerG2 have partnered for the scale-up of carbon materials for supercapacitors and lead-acid batteries.

EnerG2 has developed a carbon technology platform that enables large-scale production of carbon materials. Seattle-based EnerG2’s patented carbon material is designed for supercapacitor electrodes and as a performance additive in start-stop lead-acid batteries in automotive and industrial applications. The two companies will jointly further develop the materials, expand capacity and extend global presence with a focus on Asia and Europe.

US sodium battery manufacturer Aquion Energy (Aquion) has received $36.8m in a series E venture finance round.

The Pennsylvania-based maker of sodium batteries for grid storage will use the investment to support customer-facing resources, scale-up production and expand the manufacturing facility.

Solar company Canadian Solar Solutions (Canadian Solar) is to supply 4MW of lithium-ion energy storage to support the Independent Electricity System Operator (IESO) grid in Ontario, Canada.

The energy storage system is aimed to provide 2.76MWh reactive power, voltage support and bulk energy storage services to the IESO using stationary lithium battery technology. The Canadian solar specialist is contracted for maintenance and operation services for 36 months.

Southern California Edison (SCE) has selected five energy storage companies to provide 261MW of grid-connected storage by 2021.

STEM will provide 85MW of behind-the-meter-storage, 50MW from Advanced Microgrid Solutions of battery-based "hybrid electric building" projects; Ice Energy 25.6MW of thermal energy storage; while NRG Energy will develop a 0.5MW grid-tied battery energy storage system.
