Thermal energy storage system goes online at IIT Kanpur

The thermal energy storage system with a 775 tonnes-of-refrigeration heat rate is installed at IIT Kanpur’s Centre for Environmental Science and Engineering building. It is part of an urban pilot under a joint Indo-US project called UI-ASSIST on Smart Grid and Storage Technology. 

IndianOil turns to gas, not green hydrogen, to reduce Delhi bus emissions

The public sector energy company has opened a compact reformer plant at Delhi Transport Corporation’s Rajghat bus depot. The facility will produce hydrogen-enriched compressed natural gas as a bus fuel. A trial period will see 50 gas-powered buses run on the blended fuel with fuel economy and emissions monitored.

Indian-led start-up raises Swiss funding for solar diagnostic tool

Swiss-based SmartHelio claims to have witnessed a near 200% jump in demand for its deep-data driven solar asset management solution, which plugs into solar panels or energy storage systems. Sales of the internet-of-things enabled, cloud product have leapt in the last six months.

Over 26,000 register for World Solar Technology Summit tomorrow

The Summit will see the signing of four partnership agreements, including one between India’s Ministry of New and Renewable Energy, World Bank, and International Solar Alliance.

New cathode for sustainable, high-density lithium-sulfur batteries 

Shiv Nadar University researchers have synthesized sulfur-rich copolymers from petroleum and agricultural waste as cathode materials for Lithium-Sulfur (Li-S) batteries. IIT-Bombay, which is developing a Li-S battery prototype based on the technology, recorded an average Coulombic efficiency of 99.3% after 500 cycles at 1C, one hour rate of charge and discharge, for the cardanol/sulfur copolymer cathode containing 2.5wt% reduced graphene oxide (rGO).

The long read: The state of solid-state batteries

Solid-state batteries hold the potential to overcome many of the limitations of today’s lithium-ion storage technologies. Though they have been a research topic for more than 30 years, and more recently have seen billions of dollars poured into their development by leading carmakers and electronics giants, commercial development is still extremely limited. Major roadblocks remain in the way of both device performance and industrial-scale processing. pv magazine recently caught up with solid-state’s research community for a look at where the technology stands.
