Utility Scale Storage

Australian renewable gen-tailer Zen Energy is set to build the second-largest battery energy storage system in the state of South Australia, in a move that is expected to improve the reliability of electricity supply.

ETIP PV explains how the energy system integration of PV should transition towards a smart and digitalized system, supported firstly by digitalized PV manufacturing and system and secondly by intelligent distribution control.

Germany made progress with its hydrogen strategy, while Australia announced plans for a hydrogen feasibility study.

Gujarat Urja Vikas Nigam Ltd. (GUVNL) has started accepting bids to set up 250 MW/500 MWh of standalone battery energy storage systems (BESS) connected to the Indian grid. It has also tendered for the development of up to 1 GW of solar projects in India.

Scientists in Korea have built a green hydrogen system prototype that embeds a PV generation unit based on photoanodes made of perosvksite solar cells. The device purportedly achieved a solar-to-hydrogen efficiency of 9.8% for a device with a size of 0.25 cm2, and 8.5% for a system measuring 123.2 cm2.

Australian researchers have designed a new catalyst that has the potential to deliver a new generation of lithium-sulfur batteries that can be charged in less than five minutes, instead of several hours.

Spanish utility Endesa has activated a 1.1 MW/5.5 MWh redox flow battery in Spain. It says it is the vanadium redox flow storage system connected to a PV plant in Europe. It is situated near Mallorca, in the Balearic Islands.

Western Australian government-owned utility Synergy has commenced construction of its third grid-scale battery as the state government looks to ramp up energy storage capacity to support its planned transition from coal-fired power generation to renewables.

Maharashtra State Electricity Distribution Co. Ltd (MSEDCL) has started accepting bids to provide 1,000 MW/8,000 MWh of grid-connected energy storage capacity from pumped hydro storage throughout India.

Battery storage revenues in Britain are well below historic highs but an appetite for storage capacity remains. Electricity system-operator modernization, increased competition, and new opportunities could all shape the future of British battery energy storage systems (BESS’).
