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.

Servotech Power Systems, with the support of the German Development Agency GIZ, has installed ten portable solar rooftop systems at the Swaminarayan Akshardham temple complex in the Gandhinagar district of Gujarat. 

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.

New research has categorized all existing fault detection and localization strategies for grid-connected PV inverters. The overview also provides a classification of various component failure modes and their potential causes in a tabular form.

The Genap Energy Cover uses HyET Solar Powerfoil thin-film solar modules, rated at 12.0% efficiency, for agricultural water storage and reservoirs, with an initial focus on the greenhouse and horticulture markets in the Netherlands. Genap said a 12kWp test setup had a generation density of 60W/m2, rising to 120W/m2 within a year, with an eventual target of 165W/m2.

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.

To decarbonize the cooking sector, India’s premier energy utility NTPC has partnered city gas distribution company Gujarat Gas Limited on a pilot project to supply green hydrogen-blended piped natural gas. 

Stanford researchers develop a device that harvests energy from the temperature difference between the PV cell and the air.

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.

GIZ, Germany’s development agency, has partnered with India‘s Ministry of New and Renewable Energy to follow up on its successful “kW-to-kWh” study, which has become a quality benchmark for MNRE’s projects in India. PI Berlin acted as lead consultant on the project, and Asier Ukar, senior consultant and managing director of PI Berlin S.L., shares some of the key conclusions.
