An Indian-US research team has fabricated a four-terminal perovskite-cadmium telluride tandem solar cell by utilizing a highly conductive and sputtered transparent electrode to increase the current density of the bottom cell. The tandem device combines a 18.3%-efficient top perovskite cell and a 19.53%-efficient cadmium telluride bottom device.

Researchers at the University of South Carolina have successfully transitioned their highly-durable lithium-sulfur battery technology from coin to pouch cells and reported competent energy densities.

Scientists in South Africa have modeled a photovoltaic system connected to a thermoelectric cooling device and have found it may produce around 9.2% more electricity than conventional PV system without cooling. The research team claims the proposed system guarantees a minimum cost saving of 10.56%.

Spread across 6.3 lakh sq.ft. and built with an investment of INR 200 crore (EUR 22 million), the new campus in Bengaluru will host a global innovation hub, training center, R&D center, skill center and digital hub with a capacity to accommodate over 8,000 professionals.

GAIL (India) Ltd, India’s largest natural gas company, has set up a green hydrogen plant that can produce 4.3 tonnes of hydrogen per day through 10 MW PEM (proton exchange membrane) electrolyzer units.

The road to net-zero emissions in India doesn’t require herculean efforts. We can get there by wholeheartedly adopting renewables, investing in innovation and technology, and promoting public-private partnerships to build a better, cleaner, and more sustainable India for generations to come.

The Indian Army has received a hydrogen fuel cell bus under its collaboration with Indian Oil Corp. Ltd (IOCL) for demonstration trials of this technology. The bus promises a mileage of 250-300 km on a full 30 kg onboard tank of hydrogen fuel.

Through the agreement, Reliance gets access to Nel’s technology platform for manufacturing alkaline electrolyzers.

IEA-PVPS is poised to launch a new format for expert engagement. It will include an action group on agrovoltaics, as well as a collaborative effort to match agriculture and solar generation. It aims to unlock the potential of agrivoltaics, optimize land use efficiency, enhance agricultural resilience to climate change, and foster social consensus for solar development.

Hygenco Green Energies has signed a memorandum of understanding (MoU) with Mitsubishi Heavy Industries and Mitsubishi Power to deliver green hydrogen-/ammonia-fired gas turbine combined cycle (GTCC) power plants.
