Distributed Storage

Auxsol’s new three-phase hybrid inverters have efficiency ratings of 97.8% and European efficiency ratings of 97%. They are available in five versions, with power outputs ranging from 5 kW to 12 kW.

Developed by Chinese researchers, the novel hybrid storage technology may achieve an efficiency of over 80% and be applied in distribution and transmission grids. The proposed combination is reportedly able to offer the advantages of gravity energy storage and power-based storage systems in a single solution.

Sonnen has introduced a new software solution to seamlessly integrate heat pumps into private household energy supplies and enhance grid stability. The company’s initial partner is heat pump manufacturer NIBE, but additional partners are expected to join in the future.

ZincFive is supplying battery systems for Advanced Power & Energy’s hydrogen-fueling microgrid and pilot DC fast-charging station in Greenville, Pennsylvania

Mitsubishi Electric has launched a demonstration experiment to assess the efficiency of heat pumps in demand-response control on the Aran Islands in Ireland and San Pietro Island in Italy. As part of the European Union’s REACT project, solar, wind, and storage solutions will also be implemented to enhance the energy self-sufficiency of isolated islands.

Germany’s development bank, KfW, is financing a new minigrid project in Senegal with a $138.8 million loan.

Deye’s new three-phase hybrid inverters have efficiency ratings of up to 97.60% and European efficiency ratings of 97.0%. They are available in five versions, with power outputs ranging from 29.9 kW to 50 kW.

Brisbane-based Li-S Energy has developed a 20-layer battery cell utilizing 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.

Queensland-based flow battery company, Redflow, has commissioned a 30 kWh zinc-bromine flow battery for the Brisbane City Council.

A Japanese consortium is now testing a 100 kW fuel cell system in Tokyo. The system uses green hydrogen and waste plastic hydrogen to provide heat to an industrial building. The demonstration aims to establish an urban hydrogen energy utilization model that combines global and local hydrogen sources.
