The International Energy Agency (IEA) has issued its first report on the importance of battery energy storage technology in the energy transition. It has found that tripling renewable energy capacity by 2030 would require 1,500 GW of battery storage.

Researchers at the Korea Advanced Institute of Science and Technology (KAIST) have identified a high-energy, high-power hybrid sodium-ion battery capable of charging in just a few seconds. The system integrates anode materials typically used in batteries with cathodes suitable for supercapacitors.

Netherlands-based developer Giga Storage has obtained the irrevocable permit for the construction of a 600 MW/2,400 MWh battery energy storage system (BESS) project in Belgium.

EcoFlow has launched a new air-to-water heat pump for residential applications. The new product, equipped with R290 refrigerant, is available in 9 kW and 20 kW versions. The US-headquartered manufacturer has also developed a new smart immersion heater, which uses surplus solar energy to heat up water. It is compatible with all available rooftop PV systems.

The Dutch government has earmarked €100 million ($106.7 million) of subsidies for the deployment of battery storage alongside PV projects. The funds are part of a €416 million subsidy program announced last year to alleviate grid congestion.

Researchers in India have simulated a 4 kW solar power-based hybrid electric vehicle (EV) charging station using a three-stage charging strategy and found that the station is capable of charging 10–12 EVs with 48 V 30 Ah lithium-ion batteries.

The Croatian Energy Market Operator (HROTE) has announced a much-anticipated, €257.2 million ($273.5 million) round of renewable energy auctions. It has allocated the biggest quota of 450 MW for solar projects and has set a deadline to award the subsidies by year’s end.

The European Commission (EC) has proposed the European Solar Charter (ESC) in response to the challenges facing the continent’s solar manufacturing industry. The document sets out a series of voluntary actions to be undertaken to support the EU photovoltaic sector and bears no mention of EU trade tariffs or restrictions on cheap solar panel imports.

Researchers in Japan have developed a novel cathode material for rechargeable magnesium batteries (RMBs) in the form of rocksalt oxide. This new material reportedly enables efficient charging and discharging even at low temperatures.

Battery research is advancing to address issues in the lithium-ion development process and concerns about safety and aging. Vehicle-to-everything (V2X) tech, meanwhile, is in the starting blocks, but interoperability is the key hurdle to achieving mass market penetration.
