Brisbane-based Li-S Energy has developed a 20-layer battery cell utilising semi-solid state lithium sulfur battery technology. The company claims the new cell displays nearly double the gravimetric energy density and a comparable volumetric energy density to lithium-ion cells.

Wiki-Solar’s latest league table of utility-scale solar project developers shows that only six renewable specialists occupy the top 20 spots.

Australian researchers have developed a novel adaptive decentralised control strategy for electric vehicle (EV) integration, incorporating both microgrid and EV-side conditions into the primary frequency control. They have proposed new indices to evaluate the charge and discharge capabilities of EV batteries, as well as the satisfaction levels of EV owners.

Chinese battery industry heavyweight CATL has unveiled a novel condensed matter battery technology with an energy density of up to 500 Wh/kg. The company said it can achieve mass production within this year.

Salgenx has developed a way to produce graphene on demand from its saltwater flow battery. The tech exploits the electrochemical properties of the battery’s cathode to exfoliate graphite into individual layers of graphene. The company says it can produce graphene for less than USD 1.25 ($1.85) per gram, providing storage businesses with an additional revenue stream.

San Miguel, which is now behind on its original plan to deliver a 1 GW/1 GWh fleet of battery energy storage systems (BESS) by the end of 2022, continues to roll out big batteries across 32 sites in the Philippines, in order to integrate up to 5 GW of renewables into the island nation’s grid.

Germany’s SMA has developed a modular lithium-ion solution for commercial storage applications. It comes in two versions, with capacities of 32 kWh and 56 kWh. The two variants feature SMA Sunny Tripower Storage X battery inverters, with up to 8,000 complete charge cycles.

Storage specialist Fluence has launched Ultrastack, a battery energy storage system (BESS) for storage-as-transmission assets. It is designed to help network owners and operators to manage renewables curtailment, increase the use of power lines, and limit congestion.

Last year was another landmark 12 months for energy storage, with all indicators pointing to a massive surge in demand. Supply chain instability and inflation saw battery prices rise, but the industry demonstrated an ability to swiftly react to geopolitical developments. Marija Maisch examines five trends driving the market.

Sono Motors, a solar electric-vehicle manufacturer in Germany, has terminated its Sion passenger car development program, as it has failed to secure enough funding to support pre-series production. It says it will now focus exclusively on retrofitting and integrating its patented solar technology into third-party vehicles.
