A new study by CEEW Centre for Energy Finance assesses the competitive advantage that China has over India and presents a suite of short-term and long-term interventions required for a globally competitive solar manufacturing sector in India.

International thinktank IEEFA says there are 50 viable green hydrogen projects under development with an estimated renewable energy capacity of 50 GW and the potential to produce 4 million tonnes of the fuel annually.

Gujarat State Electricity Corporation Limited (GSECL) has invited bids to set up an aggregate 110 MW of grid-connected solar power plants across three substations of the Gujarat Energy Transmission Corporation Limited (GETCO). Bidding closes on September 16.

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).

Researchers from the Massachusetts Institute of Technology have identified sites where hydrogen could be produced via PV electrolysis at prices ranging from $1.90/kg to $4.20/kg in the United States by the end of the decade.

Mitesh Patel, Renewables Director-Asia, US-headquartered EPC player Black & Veatch, speaks to pv magazine about the key trends driving the solar market, especially in Southeast Asia, and strategies to improve the bankability of PV projects.

Bids are invited to install a 2,285 kWp grid-connected rooftop solar system at G.B. Pant University Of Agriculture And Technology. The plant is to be set up under the RESCO model. Ceiling tariff for over 25 years is fixed at Rs 3.5/kWh.

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.

The state-owned electronics manufacturer has signed a memorandum of understanding for technology transfer with Vikram Sarabhai Space Centre of Indian Space Research Organisation.

Bids are invited from Indian manufacturers to supply polycrystalline solar modules with an efficiency of a minimum 16.75%. Bidding closes on September 3.
