Distributed Storage

Each expansion unit adds another 13.5 kWh of storage capacity to the original installation with a maximum of three such units connected to a single Powerwall. Now available in the US, the new product comes at a lower cost and slashes installation time by roughly half to 22 minutes.

The ThermIon project is intended to take into account the entire process chain from the pretreatment of the brine to lithium extraction and lithium carbonate or lithium hydroxide crystallization to the controlled return of the brine. The new process is intended to be both environmentally friendly and economical.

MEAG, the asset manager of Munich Re and Ergo Group, has acquired all shares in the ready-to-build storage project in the German state of North Rhine-Westphalia. SMA Altenso is to provide the full EPC and O&M services for the battery park, which is scheduled to go online in the second half of 2025.

Solinteg has developed the IntegOne HSH, a residential solar storage system that combines a single-phase hybrid inverter with one or two batteries. Up to 10 systems can connect in parallel, offering a maximum efficiency of 97.6%.

Part of mining company POSCO Argentina’s Sal de Oro integral lithium project, the plant was inaugurated at the General Güemes Industrial Park in the city of Salta. It is estimated to produce 25,000 tons of lithium hydroxide per year.

The method developed at the Technical University of Munich is intended to make several hundred thousand charge and discharge cycles possible in the future instead of a few thousand. A special protective layer for the zinc anodes of the batteries is crucial.

US-based Bluetti has developed a new energy storage system (ESS) that offers up to 154.8 kWh of storage and 60 kW of output by connecting up to three systems in parallel. It includes an inverter and a voltage controller with up to seven batteries.

The company said in a statement that it was “firm in its commitment to the Andalusian Green Hydrogen Valley and will continue to invest to create value and employment in the municipalities of San Juan del Puerto and Gibraleón.”

Researchers in Canada have created an experimental workbench for aboveground compressed air energy storage. Experimental data calibration reportedly ensured model accuracy with a mean absolute percentage error below 4.0%.

The startup is developing LDES technology that, housed in a 40-foot container, would have an estimated power of 100 kW and a capacity of about 100 hours with a useful life of more than 30 years and an LCOE of less than $0.05/kWh in its early stages of industrialization.
