PV-powered direct air electrolysis module to produce hydrogen from moisture in air
Scientists in Australia have developed a new way to produce hydrogen using water from the atmosphere. They claim their new module can ensure stable performance and provide green hydrogen for remote areas.
Solar perovskite tandems and potential-induced degradation
Scientists have found that perovskite solar cells and perovskite-silicon tandems might be vulnerable to potential-induced degradation. They exposed tandem cell devices to PID stress and found that they lost as much as 50% of their initial performance after just one day.
Meritsun unveils 15 kWh lithium-ion battery for residential applications
Chinese battery provider Meritsun says its new 48 V battery has a storage capacity of 15 kWh and a rated capacity of 300 Ah.
Hydraulic robotic cleaning solutions for ground-mounted solar plants
France’s AX Solar Robot has unveiled two battery-free, hydraulic-powered cleaning solutions for ground-mounted PV plants. It is also distributing a modular battery-powered solution suitable for rooftop installations.
PV-driven rechargeable control module for ‘cyborg cockroaches’
Japanese researchers have built ultra-soft PV devices and ultra-thin electronics that can be placed on the curved abdomens of cockroaches without affecting their mobility. The system can be used to monitor hazardous areas, or for urban search-and-rescue operations.
The Hydrogen Stream: Condensed hydrogen on smooth surfaces can sharply exceed liquid hydrogen density
A German-US research team has shown that hydrogen condenses on smooth surfaces at a very low temperature, forming a super-dense monolayer that reduces the volume to just 5 liters per kilogram of H2. Dutch researchers, meanwhile, have published a new study on hydrogen storage in porous rocks, and Itochu said it is moving forward with hydrogen plans in Japan and South Africa.
Sharp unveils black-framed 410 W half-cut solar panels
Sharp’s newest PV modules feature white backsheets and are made for the needs of design-oriented customers.
Solar tech theft rising in Germany amid supply bottlenecks
The Saxony State Criminal Police Office in Germany has blamed the energy crisis and growing solar demand for an increase in the theft of modules and inverters.
Storing renewables with seawater batteries
Scientists in Germany have studied how seawater batteries could be used for renewables storage and desalination.
Australian pumped hydro storage project secures funding
The government of New South Wales, Australia, has announced funding for five pumped hydro schemes spread across the state, as it looks to deliver large-scale energy storage and firming capacity.
