Energy Storage

In the next ten years, according to Milanese consultant REF-E’s simulations, storage in Italy will mostly be driven by opportunities in the ancillary services market. After 2030, when renewables will provide most electricity, REF-E believes the price spread between different hours of the day should be high enough to cover the cost-per-cycle of energy-intensive storage. Energy expert Virginia Canazza discussed the topic with pv magazine.

The Chinese manufacturer has upgraded its commercial application battery with a dissipative balancing technology that, it is claimed, will make the storage system suitable for different load conditions. Each battery module is sold with a capacity ranging from 100 to 200Ah and a storage capacity of 7.68kWh.

The portable storage system contains lithium batteries, a charger, and an inverter, all fully integrated into a sealed and protective case.

A 100kW/1.5MWh zinc-air battery will be installed in Queens, New York, in combination with a combined heat and power system and a PV array. The pilot project is intended to demonstrate the long-duration energy storage capability of the zinc-air battery.

Growatt’s new AXE LV battery covers a wide range of capacities, from 5kWh to 400kWh, and can support off-grid systems with power outputs of 3kW to 30kW.

US researchers suggest that by 2050, when 94% of electricity comes from renewable sources, approximately 930GW of energy storage power and six and a half hours of capacity will be needed to fully cover demand for electricity in the United States.

Harwell Campus will provide a testbed for energy storage technologies coming from three U.K.-based innovative businesses, bringing their solutions one step closer to the market.

The system delivered by French energy giant TotalEnergies will power Kulara Water’s bottling facility in Siem Reap Province.

Scientists in Italy designed the prototype as a microcavity enclosing a molecular dye known as Lumogen-F orange (LFO). The charging power of the device is described as super-extensive, meaning that it increases faster with battery size.

Cape Town-based solar crowdfunding platform The Sun Exchange in April announced completion of its largest funding call, for US$1.4 million to finance what it described as a 510kW solar-plus-storage facility for Zimbawean food company Nhimbe Fresh. With the first part of a planned three-phase “going solar” transformation of the business complete, pv magazine spoke to The Sun Exchange founder and CEO Abraham Cambridge, and to Nhimbe Fresh chairman Edwin Masimba Moyo.
