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.

The IIT Kanpur-incubated startup has introduced ZincGel battery technology that offers energy efficiency at par with lithium-ion products but with twice the lifecycle and negligible operational cost, which can lead to significant savings for two-wheeler EV operators.

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.

Tamil Nadu based Next Automation has come up with a tractor-mounted hydraulically operated arm as a fast, accurate, cost-effective, and water-efficient cleaning solution for panels in solar farms.

Germany’s Ostermeier H2ydrogen Solutions has developed an electrolyzer that works with tap water, with bottles to store hydrogen and a fuel cell or a Wankel engine to produce electricity. The system has a capacity ranging from 1kW to 100 kW, which corresponds to hydrogen production of 0.2-20 Nm3/h.

IndianOil, Larsen & Toubro, and ReNew will hold an equal stake in their proposed joint venture to develop, execute and own green hydrogen assets in India. Additionally, IndianOil and Larsen & Toubro will form a JV for the production and sale of electrolyzers.
