Distributed Storage

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 at demonstrating 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.

Germany-based Linde Engineering has started up a full-scale pilot plant in Dormagen to showcase how hydrogen can be separated from natural gas streams using its membrane technology. Furthermore, Abu Dhabi-based renewable energy developer Masdar has teamed up with French energy giants Engie and Totalenergies on two separate hydrogen projects and Sweden’s nuclear power company OKG signed its first contract with an external buyer to enter the hydrogen market as a producer and supplier.

As part of the EU Horizon 2020 CIRCUSOL project, Belgian PV installer and investor Futech investigated the technical and economic feasibility of integrating a second-life battery storage system at an existing 2MW solar plant in Belgium. The system originates from the automotive industry and was successfully commissioned in August 2021.

Australian startup Endua’s plan to make modular hydrogen-powered energy generation and storage systems has been given a financial boost, as the federal government has provided it with almost AUD 1 million ($719,800) to help it commercialize its technologies.

France-based FHE Group has developed a 2.5 kWh storage device that can store electricity as heat during the day and release this heat at night to power a heat pump for space heating and hot water. According to the manufacturer, it can retain over 95% of its initial performance after 20,000 cycles.

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.
