Researchers led by Korea’s UNIST developed a new redox flow battery concept that utilizes iron and chromium ore for redox chemistry. The proposed battery configuration may reportedly achieve a stable lifetime of 500 cycles, and a high-energy density of 38.6 Wh L−1.

Alessandro Barin, CEO of FuturaSun, spoke with pv magazine at the recent Intersolar 2023 trade show about the PV module manufacturer’s plans to expand in China and its home market of Italy. He said European and Chinese manufacturers take different approaches to new factories, but the two sides will need to come together to build a sustainable global supply chain.

Huadian Energy’s new 1 GW solar plant in Tianjin, northeastern China, supports water-surface halogen production and underwater aquaculture.

California-based SEG Solar says its new panels have a temperature coefficient of -0.30% per degree Celsius. They come with a 30-year power output guarantee for 87.4% of the initial yield.

Scientists in Australia have provided a comprehensive review of all strategies and technologies that can be used to increase the dispatchability of solar power with reduced use of storage. They focused their efforts, in particular, on forecasting and controlling PV power.

A year after achieving what at the time was a world record efficiency for a tandem perovskite-silicon solar cell, scientists from EPFL and CSEM published a paper showing the technical features of the device and how that result was made possible. The key was regulating the perovskite crystallization process using an additive in the processing sequence.

Sumitomo says that its 2MW/8MWh vanadium redox flow battery achieved a 99% operating rate at San Diego Gas & Electric’s (SDG&E) facility in California. The battery is expected to retain a capacity rate of 90% or more for 20 years in the electricity market.

An Italian research group has assessed the advantages of combining solar power generation in greenhouses with vertical farming. The scientists claim this new approach offers better land use while increasing agricultural yield.

Dutch Economy Minister Micky Adriaansens said this week that she aims to make it impossible to install solar farms on agricultural land, with some unspecified exceptions. The plan has raised concerns at Holland Solar, with the trade group warning of potential damage to farmers and solar project developers.

China National Offshore Oil Corp. (CNOOC) says it has completed a 40 MW solar-plus-storage plant at an altitude of 3,000 meters. It is connected to 6 MW/12 MWh of battery storage and hosts grazing farm animals.
