Battery storage

The latest version of the storage system from the German manufacturer can store up to 55 kWh. Sonnen ensures a lifespan of 10,000 charging cycles.

Researchers have proposed a new battery performance standard for Australia and possibly the world. If adopted, the standard could clarify consumer confusion around which energy storage system is right for them.

Dubai-based Weco has unveiled a new lithium battery solution that can operate in parallel as a low-voltage storage system or in series as a high-voltage battery with no hardware changes. The batteries can be mounted on walls or set up in a stack configuration.

According to new numbers released by the China Energy Storage Alliance, the country’s storage capacity topped 32.4 GW at the end of last year. The association said the storage market is expected to continue to grow steadily in the years ahead.

The French oil and gas company will develop the vehicle with engineering compatriot Gaussin. Intended for the Airbus industrial site in Toulouse, the vehicle will be equipped with a lithium-ion battery made by Total subsidiary Saft and will be able to tow two 30-ton fuel tanks.

The startup claims to be “the world’s top supplier of graphene” and plans to release a non-flammable, environmentally friendly lithium battery that can charge “18 times faster than anything that is currently available on the market” — within the next year.

Specialist Alencon Systems teamed up with U.S. utility Duke Energy to look at some of the challenges faced by energy companies when adding battery storage to operational solar installations. Do you go for DC-coupled or AC-coupled? And with what sort of grounding scheme?

German production equipment provider Schmid and Saudi chemical group Sabic are planning to begin activities at a new factory in Saudi Arabia, with production being expected to begin in 2021.

A German-Israeli research group has gathered for three days to discuss which storage technologies may outperform lithium-ion batteries in the future. They concluded that there is no such a thing as a “post Li‐ion” era in sight. They recommended a “side‐by‐side” approach for multiple technologies in different applications, as well as the hybridization of technologies. The group highlighted the strong potential of redox flow storage, which in their view may outperform Li‐ion, although only for stationary applications.

The Israeli inverter maker again posted a robust set of quarterly figures but is anticipating a dip in performance during the current three-month window as pandemic-driven lockdowns take effect in its markets.
