Energy Storage

A pair of researchers from the University of California San Diego have proposed to precompute certain data when the grid is flooded with solar or wind power, and then store it on servers for later use.

After the deluge of announcements last year, 2022 will see the trickle of big batteries actually operating in Australia turn to a flood. According to Rystad Energy, the country’s battery capacity is set to double before the year is out.

Standalone power systems utilising solar PV and battery technology continue to gain traction in the Australian market with New South Wales Government-owned network service provider Essential Energy announcing it will seek input from customers living at the “edge of the grid” as it seeks to expand its roll out of the off-grid technology.

Renewable energy investors’ appetite for large-scale development in Australia appears far from sated with the New South Wales Government revealing almost 50 new solar PV, wind and energy storage projects, totalling more than 34 GW, have been proposed for the South-West Renewable Energy Zone.

The Western Australian coastal town of Kalbarri can now be powered by an entirely renewable energy solution utilising rooftop solar and wind generation coupled with battery storage with state government-owned utility Western Power confirming the state’s largest renewable energy microgrid has been commissioned.

Developed by French start-up Ecosun, the trailer is equipped with 15 solar panels with output of 360 W and batteries with a storage capacity of 23 kWh. It can be used for construction sites, military camps and water pumping systems.

Construction has commenced on an off-grid solar PV and battery energy storage system which will help power Australian-headquartered resource major BHP’s estimated $1 billion Nickel West mining operation in regional Western Australia.

SDG&E and Sumitomo Electric complete a pilot microgrid project in California that successfully powered utility customers solely with energy stored in a flow battery.

Scientists in Korea have developed an efficient synthesis route to produce a novel co-doped anode material for rechargeable seawater batteries. They developed a one-step plasma-in-liquid process to synthesise nitrogen and sulfur co-doped carbon-based anode material, which displayed great potential for seawater batteries.

The analyst also forecasts strong growth for the storage business and a significant increase in PPAs for photovoltaic projects in Europe. It also said the newly installed PV capacity for 2021 reached 183 GW.
