US scientists have utilized a nanochannels device to cool down the operating temperature of a commercial PV module and have found that the proposed technique is able to improve power yield by up to 32.8%. Spray droplets are dispersed over the nanochannels device in order to eliminate the need for a continuous supply of a coolant.

Developed by Canadian start-up Salient Energy, the zinc-ion battery has a rated capacity of 60 Ah, a nominal voltage of 1.3 V, and a volumetric energy density of 100 Wh/L. The device measures 26cmx24cmx1.2cm and weighs in at 1.3 kg

Japanese glass manufacturer AGC has developed a building-integrated PV (BIPV) panel for different building requirements. It can be installed on facades, canopies, and curtain walls where normal glass can be placed.

Japan’s Panasonic claims its new pilot solar-plus-hydrogen facility marks the first attempt to create a factory powered by 100% renewables, via the full-scale use of hydrogen.

Developed by an MIT spin-off, the device is based on a standard, two-electrode electrochemical cell containing conductive polymers, a carbon-graphene hybrid, and a non-flammable liquid electrolyte. The battery cells were tested to perform for 12,000 cycles at 100% depth of discharge.

The new product relies on 23.4%-efficient solar cells and features a short-circuit current of 10.8 A. It can be folded into a briefcase and is claimed to be an ideal solution for camping and outdoor activities.

The UK Department for Business, Energy and Industrial Strategy has published new research showing that hydrogen leaks could have an indirect climate-warming impact, partly offsetting efforts to reduce carbon dioxide emissions.

Swiss Clean Battery is set to start commercial production of its pure solid state batteries in Switzerland. The batteries are based on a protected electrolyte made of a solid ion conductor, which helps to maintain internal resistance and capacity. The fixed ion conductor is formed in the battery cell itself, similar to a multi-component adhesive.

Bosch’s new solid oxide fuel cell prototype has an electrical efficiency of more than 60% and an overall efficiency above 85%. It also has a targeted power output of 10 kW and can produce up to 3 kW of thermal energy.

US scientists have developed a battery that can retain 92% of its initial capacity over periods of 12 weeks, with a theoretical energy density of 260 W/hour per kg. It was built with an aluminum anode and a nickel cathode, immersed in molten-salt electrolyte.
