The new cobalt-free battery yields about 60% greater energy density than conventional lithium-ion batteries for an equivalent weight and volume and sustains unprecedented 1,000 cycles.

Swedish battery maker Northvolt has developed its first sodium-ion battery in partnership with Uppsala University spinoff Altris. The cell has been validated for an energy density of more than 160 Wh/kg and is designed primarily for energy storage applications.

Researchers at the University of Hong Kong (HKU) have developed a quasi-solid-state magnesium-ion battery with a voltage plateau at 2.4 V and an energy density of 264 Wh/kg. It surpasses the performance of current magnesium-ion batteries and almost matches the performance of lithium-ion batteries.

Europe’s solar installation levels are exceeding expectations and are on track to grow 30% this year from 2022, according to Rystad Energy.

European warehouses are reporting extremely high inventory levels for residential energy storage systems, with aggressive prices expected, as distributors need to start clearing their stocks, according to S&P Global.

Italian researchers studied sodium-seawater batteries (SWBs) for short- and long-term energy storage on Sardinia and found that SWBs with wave energy smoothed out power fluctuations, while enabling a fully decarbonized power generation system over the long run.

Independent energy infrastructure developer Carlton Power has secured planning consent for a 1,040 MW/ 2,080 MWh battery energy storage system (BESS). The project is expected to strengthen the resilience of the energy system in northwestern England.

Researchers in Spain have studied the impact of hydrogen production and storage technologies in risk management for energy communities with internal price-tariff systems. They found that the optimal involvement in futures markets and spot markets will depend on a community’s risk aversion and self-sufficiency.

China-based GoodWe has developed two new solutions – the ETC 100 kW hybrid inverter and the BTC 100 kW retrofit battery inverter – for commercial and industrial (C&I) solar applications.

Global demand for sodium-ion batteries is expected to grow to just under 70 GWh in 2033, from 10 GWh in 2025, at a compound annual growth rate (CAGR) of 27%, according to UK-based market research company IDTechEx.
