Distributed Storage

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.

A new solar company has entered the PV market, pv magazine learned this week at SNEC in Shanghai. The company sells everything from PV modules and inverters to racking and wallboxes.

The Allgäu company has expanded production at its headquarters in Wildpoldsried and can now produce around 120,000 systems a year. Sonnen’s move to accelerate expansion reflects the sharp rise in demand for PV home storage systems in Germany.

The IQ Battery 5P works in conjunction with the Enphase Energy System and can be configured for self-consumption, savings, or full backup functionality.

Chinese module manufacturer Hanersun has introduced six versions of its new stackable, high-voltage residential batteries, ranging in nominal capacities from 7.5 kWh to 20 kWh. The batteries, which feature lithium-iron phosphate (LFP) technology, come with a five-year warranty.

Solar electricity will have to compete with biofuels in the urban mobility landscape. Biofuels, however, have a very low energy productivity per hectare, as well as high requirements for fertilizers, pesticides, and water.

Pylontech says it plans to build a new manufacturing facility in Veneto, northern Italy. The company will operate the factory under a joint venture with its Italian partner, Energy Spa.

Chinese manufacturer Bslbatt claims that its newest product is the world’s thinnest high-voltage residential battery. It can purportedly operate for more than 6,000 cycles and has a 90% depth of discharge.
