Two French companies have collaborated on the development of the Osmo-Watt system, which is powered by solar panels. They claim that the technology can produce up to 100 cubic meters of drinking water per day.

Developed by scientists from German research institute Fraunhofer ISE, the silicon-carbide device claims 98.4% efficiency and could be used in utility-scale photovoltaic projects.

Scientists in Poland have measured the effect of solar radiation spectra in variable weather conditions on the performance of different kinds of PV module technologies. They found that amorphous silicon panels offer the best response to this effect in stationary or BIPV projects on facades, while crystalline silicon and CIS solar panels represent the best options in projects with trackers.

Université de Sherbrooke researchers have tested a new concentrator PV module for potential applications in heating, ventilation, and air conditioning systems in commercial buildings.

Gowing Bros has become the first major customer of the LAVO 40 kWh battery in Australia. The system, which features an electrolyzer and domestic fuel-cell tech, will be market-ready in June.

European scientists are designing a new type of redox flow storage system aimed at flexibly balancing power grids in the event of critical conditions. Funded by the EU, the research project is being coordinated by the Landshut University of Applied Sciences and runs until 2023.

Researchers in the Middle East have proposed a new passive technology to cool off solar modules, based on highly conductive porous materials.

Standalone solar-powered refrigerators present a $20 billion opportunity in India for vaccine storage, milk chillers, households, micro enterprises, and cold storage for farm produce, according to a new report by Gogla.

Australian researchers have analyzed different ways to improve the efficiency of PV-powered water electrolysis for hydrogen generation. They include the use of magnetic fields, light energy, ultrasonic fields, and pulsating electric fields. Energy costs remain prohibitive, but molecular movement and the redistribution of molecules in water during electrolysis could open a path to viability.

Batteries based on vanadium or zinc bromide represent the cutting edge of redox flow storage tech, an international research team has claimed. They have identified challenges and opportunities for about a dozen redox flow storage technologies, while providing estimates of their current and projected levelized costs of storage.
