Speculation will be rife as to the cause of the fire which destroyed one Tesla Megapack and damaged another in Moorabool on Friday. Investigators are waiting until the site is deemed safe to begin their forensic examination.

A British-Australian research team has assessed the potential of liquid air energy storage (LAES) for large scale application. The scientists estimate that these systems may currently be built at a cost between €300 and €600 per kilowatt-hour and that a positive business case could be favored by certain conditions, including a determined price structure in the energy market and the presence of a grid unable to support high levels of renewable energy penetration.

The PV mounting system was developed by Germany-based Goldbeck and will initially be available in the Netherlands from 2022. The company will test the new technology in a 45 MW PV project.

NREL researchers have developed interoperable SCADA protocols for PV inverters. Two new sets of codes were conceived to enable legacy inverters, which are inverters that are not capable of providing some or all of the grid support functions to participate in advanced distribution management.

French organic PV specialist Armor, and a Dutch designer specialized in integrating PV in furniture, windows and other objects, have provided the module technology for the Netherlands’ pavilion at Expo 2020 Dubai.

The system can be expanded to a capacity of up to 25 kW. Its creator – U.S.-based start-up EcoFlow – has already collected almost €4 million on the Kickstarter crowdfunding platform for its portable power supply solution.

Two Italian experts on heat pumps and PV systems recently spoke to pv magazine about economies of scale, the European market, and the maturity of heating tech. The Eurac researchers said currently available heat pumps can run at -20 C and efficiently provide hot water up to 65 C.

NASA plans to place a solar array on a tall mast to avoid lunar shading and capture uninterrupted light. It will hang a pair of PV cell blankets from a horizontal cross arm supported by the mast, anchored to a deployable tripod base.

An Australian-Russian research group has developed a silicon heterojunction solar cell based on p-type gallium-doped wafers with an efficiency of 22.6% and an improved stability. The scientists are convinced that these wafers may become a mainstream solution for the SHJ segment within the next decade.

Recent research has revealed a previously underestimated role for oxygen in limiting the performance of lithium-ion batteries. Newly published research from both Japan and the United States has sought to look deeper into the chemical reactions at the heart of lithium-ion storage; and to better characterize the cumulative effects that minuscule amounts of oxygen released during these reactions can have on battery performance and safety.
