Germany’s Home Power Solutions has developed a hydrogen storage solution with a capacity of up to 15,000 kWh. The Picea system stores excess electricity from rooftop PV systems in the form of green hydrogen.

With a new system for floating photovoltaic power plants, engineers from Germany want to make the application cheaper, higher-yielding, and safer. The result is somewhat reminiscent of a pufferfish, which also gave the system its name.

The new plan would require the deployment of around 15 GW of new PV capacity each year to 2030. The agreement also includes the gradual phasing out of all coal power plants by the end of the decade.

In the coming weeks, Western Australian mining-cum-materials recovery company Neometals will begin testing at its newly commissioned battery recycling demonstration plant in Hichenbach, Germany, the product of a joint venture with SMS Group. The Primobius facility, as it’s named, has already garnered considerable attention and is a finalist in 2022’s prestigious German Sustainability Award. “We want Primobius to be the preeminent recycler in the world,” the company’s managing director, Chris Reed, told pv magazine Australia.

A number of Australian battery material recovery projects got off the ground this week, including the completion of Western Australian outfit Neometal’s battery recycling demonstration plant, a Queensland-Japanese joint venture studying the extraction of cobalt from copper tailings as well as the funding of Sydney-based startup Novalith.

A report from Australia’s Future Battery Industries Cooperative Research Centre which analysed the development of battery hubs in the U.S., Germany and Japan, has found that co-location and cooperation between industry and government were key to hub success. For Australia to play the same game, it will have to leverage its wealth of resources, and clean up its act along the way.

Belgian materials company Umicore has signed a contract with Australia headquartered Vulcan Energy Resources to purchase up to 42,000 tons of lithium hydroxide over a five year period beginning in 2025. The material will be used in Umicore’s production of cathode materials for lithium-ion cell manufacturers.

Meyer Burger plans to start selling a new building-integrated PV product from 2022. It says the solar tiles have a high energy yield, with simplified installation and the ability to also provide heating. German engineering company paXos designed the tiles.

German equipment supplier M10 and research institute Fraunhofer ISE will unveil a new prototype stringer for shingled module layouts at the Intersolar Europe trade show later this week. Employing an offset layout for the shingles, the approach promises a relative efficiency gain of up to 6%, compared to a conventional half-cell module.

The German research institute has unveiled a novel interconnection technology for shingled PV modules that eliminates the need for electrically conductive adhesives and screen-printed busbars. It consists of an 8-μm-thick aluminium foil that is joined to the silicon nitride (SiNX) passivation via laser metal bond (LMB). When integrated in a solar module, the efficiency of the new interconnector improved by 0.7%.
