Utility Scale Storage

Australian energy major AGL has fast-tracked the closures of its two biggest coal-fired power plants by several years as it pushes ahead with plans to demerge in response to the ongoing market shift towards renewable sources of electricity.

Temple University researchers have found that managed sheep grazing on an acre of recovering agricultural soil with native plants may sequester 1 ton of carbon per year, which could accumulate for 12 to 15 years before reaching saturation.

Scientists in South Korea developed a porous carbon material that, when applied as a coating to the separator film in a lithium-sulfur battery, was shown to reduce an unwanted side effect and improve the battery’s performance and reliability. The coating is based on methylene blue, a type of salt commonly used in textile dying.

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.

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.

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.

Gelion’s zinc-bromide Endure batteries will undergo commercial tests at the 1.2 MW Montes del Cierzo testing field Spanish renewable energy company Acciona Energía operates in Navarra, in the north of Spain.

On the company’s Q4 earnings call, the world-leading EV manufacturer again prioritised delivering cars over growing low-margin energy storage products, while solar products were barely noted. Both verticals grew though, solar by 68% and storage by 32%.
