British start-up Gravitricity secured funds from the UK Department of Business Energy & Industrial Strategy (BEIS) to build its second gravity-based storage project. The feasibility study is expected to be finalised by the end of this year.

Australian technology company Lavo’s innovative energy storage system – based on storing green hydrogen in a patented metal hydride – has attracted the attention of the UK government which has provided financial backing to allow for a demonstration facility to be installed in England’s northwest.

The stadium of German football club SC Freiburg will host a 2.4MW rooftop solar array that will be built with heterojunction modules provided by Swiss manufacturer Meyer Burger.

TOPCon solar modules will gain more market share if their average efficiency, already higher than that of PERC panels, continues to improve, according to Stefan Glunz, PV research chief at Germany’s Fraunhofer Institute for Solar Energy Systems ISE. In an upcoming pv magazine webinar on the potential of TOPCon tech, Glunz will show how to reduce costs and increase efficiency.

French start-up Rosi Solar has developed an industrial solution claimed to be capable of recovering high purity silicon, silver and copper contained in end-of-life PV modules. The company’s technology is based on a pyrolysis process that makes it possible to isolate the different metals from the cells.

Researchers in Italy are combining PV with latent heat thermal storage (LHTM) and other renewable energy sources to maximize clean energy consumption in buildings. The 47kW PV array and LHTM system work independently, but the scientists said that a heat pump could be used to link them.

In 2002, the Fraunhofer ISE patented the HERIC circuit for highly efficient inverters. Since then, the institute says, it has recorded out-of-court settlements in seven patent infringement lawsuits against companies from China, Taiwan and Germany.

Spanish renewables group Gransolar says backing from international financier will “supercharge” its growth plans in Australia.

Spanish renewable energy company Acciona is using a robot dog, instead of drones, to monitor a solar park in northern Chile. The device has a built-in thermal vision system that generates thermographic reports on the status of the different PV plant components, as it walks between the panel rows following a programmed route.

Researchers from Finland and Sweden have reviewed different ways to store compressed gaseous hydrogen, including storage vessels, geological storage, and other underground options.
