Indian researchers develop low-cost, durable catalyst for hydrogen production
Researchers from India’s Centre for Nano and Soft Matter Sciences (CeNS) have developed a coordination polymer based catalyst for hydrogen production that exhibited exceptionally high durability for 70 hours at a high current density of −300 mA/ cm2.
Government priority is to make Li-ion batteries in India: Transport minister
The government is acquiring lithium mines abroad to ensure raw material availability for electric vehicle battery production. Among other technology alternatives for EVs, it is looking at developing indigenous hydrogen fuel cells with hydrogen derived from biomass.
‘Spontaneous de-doping’ for 17.8%-efficient perovskite mini-module
U.S. scientists have found a new ‘de-doping’ process in perovskite solar cells that could cut production costs and produce better devices. They have used this to fabricate a mini-module with 17.8% efficiency.
IIT researchers consider fate of end-of-life solar modules
Scientists at the Indian Institute of Technology in New Delhi have taken a close look at the potential impact of growing volumes of PV waste and conducted surveys which suggest a lot more work is needed from manufacturers and policymakers to develop management systems for end-of-life PV products.
Microsoft trials hydrogen-powered data centers
The software giant has begun testing hydrogen fuel cells as a back-up power source at one of its U.S. data centers. A 250 kW pilot system successfully powered part of the facility for 48 hours and the company is now eyeing 3 MW systems to replace back-up diesel generators.
New all-iron redox flow battery for renewables storage
Scientists in the U.S. claim to have demonstrated an inexpensive, long-life, safe and eco-friendly redox flow battery. The device is said to offer coulombic efficiency of 97.9%, thanks to functional electrolyte additives, pH and elevated temperature.
New equipment for solar cell metallization
The system can metallize the front and back sides of silicon solar cells with unprecedented precision and speed, Fraunhofer ISE said. The technology is also suitable for components such as printed circuit boards or chip cards.
Norwegian tech for Korea’s giant floating solar complex
Floating PV specialist Ocean Sun and South Korean energy company EN Technologies have signed an agreement to develop the pilot projects of the 2.1 GW floating solar site planned near the Saemangeum tidal flat, on the coast of the Yellow Sea.
ARCI develops low-cost supercapacitor utilizing industrial waste cotton and seawater
The seawater-based supercapacitor exhibited maximum capacitances at a current density of 1 ampere per gram. Besides, it can last 10,000 charge-discharge cycles with 99% of capacitance retention and 99% of Coulombic efficiency.
There’s something fishy about this flow battery innovation
Scientists led by MIT have suggested chitin, a carbon and nitrogen-rich material made from waste shrimp shells, could produce sustainable electrodes for vanadium redox flow batteries and other energy storage technologies.
