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)

Australian solar technology startup SunDrive has announced “a breakthrough” in mass production compatible heterojunction technology after recording an efficiency result of 26.07% with a silver-free, commercial-size silicon solar PV cell.

For short-term storage in a 100% renewables grid, thermal energy storage located at concentrating solar power plants could compete with batteries, found a study using an idealised grid model. Seasonal storage needs could best be met with power-to-gas-to-power technology.

The US Department of Energy’s durable materials consortium is a multi-laboratory unit that stress-tests solar modules for durability. It seeks to extend the useful life of PV.

“We’re not talking about incremental improvement, this is a really giant leap,” Hysata CEO Paul Barrett told pv magazine Australia. Hysata is commercialising a breakthrough made at the University of Wollongong which effectively, Barrett says, invented a “brand new category of electrolyser” vastly improving efficiency. “This is a 20% gain. This is really a seminal moment for the hydrogen industry.”

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.

Scientists from the Massachusetts Institute of Technology have developed a system that can be operated at a voltage of around 12V, with a 95% recovery rate for lost power after cleaning. The waterless system can be operated automatically via an electric motor.

Federal Labor has promised to allocate $22 million to help establish the Lansdown Eco-Industrial Precinct being developed in northern Queensland if it wins the election in May.

A multibillion-dollar solar, battery storage, wind and potentially green hydrogen project in Victoria’s Gippsland region is moving forward after getting backing from superfund Hostplus. Originally proposed by Solis Renewable Energy, the project is now owned by Octopus Australia as part of its joint venture with CFEC.

Australia’s first astronaut believes advances in solar and space technologies and a growing capability to build and launch reliable satellites means it is now not only possible, but economically viable to build a solar PV farm based in Earth’s orbit.
