A West Australian joint venture seeking to recover high-purity vanadium from a steel industry waste product using a carbon negative process has won the support of the European Union. “We’re not the first people to look at that project, but we’re the first people to look at it through a different lens and use this type of process,” Neometals’ General Manager of Commercial and Investor Relations, Jeremy McManus, told pv magazine Australia. The project, which is still in the early stages, is already been sought out by potential offtakers “desperate to secure green vanadium,” McManus added.

The deal between Fortescue Future Industries and E.ON, one of Europe’s largest energy network operators, will see the Australian company deliver five million tonnes of green hydrogen to Germany, the Netherlands and other European cities by 2030. “For us, it’s a minimum $50 billion expenditure. And that is one I welcome,” Fortescue founder Andrew Forrest said at press conference in Berlin overnight.

Developed by researchers in Spain, the battery uses renewable electricity to melt low-cost metals such as silicon or ferrosilicon alloys to produce and store latent heat, which is in turn used by a thermophovoltaic generator to produce power. According to its creators, the device may store electricity at a cost of €10 per kilowatt-hour (AU$14.6/kWh) for a 10MWh system.

The first Model Y electric cars have rolled off the assembly line at the US electric car manufacturer’s first European factory.

Vattenfall, SSAB and LKAB have reached the halfway point in the construction of a rock cavern storage facility in a coastal city in northern Sweden. The 100-cubic-metre facility is being constructed 30 metre below ground and will begin storing green hydrogen next year.

Researchers in Spain have designed a pumped thermal energy storage system that uses supercritical carbon dioxide as a heat pump and a heat engine. The proposed system is claimed to achieve an efficiency of 80.26% and an LCOS of €0.116/kWh (AU$0.18/KWh)

German luxury carmaker Mercedes-Benz has made public its plans partner with Primobius, a 50:50 joint venture between West Australian company Neometals and Germany’s SMS Group. Mercedes has said its intention is to build a 2,500 tonne per year lithium-ion battery recycling plant in southern Germany with Primobius as its technology partner.

OnSight Technology has developed a tele-operated vehicle to clean solar arrays. It is equipped with a radiometric thermal imaging camera and an optical zoom camera backed by artificial intelligence. It has a range of 12 hours and a speed of 1.6 km per hour.

A Swedish research group has developed a device combining CIGS thin-film solar modules and an alkaline electrolyser based on a trimetallic cathodic catalyst made of nickel, molybdenum, and vanadium (NiMoV) and an anode made of nickel oxide (NiO). The electrolyser achieved an average solar-to-hydrogen (STH) efficiency of 8.5% for stable operations during 100 hours.

The Korean manufacturer and the German research centre were able to improve the performance of their jointly developed tandem solar cell by almost one percentage point.
