The state government of Odisha has approved green hydrogen and green ammonia projects of Welspun New Energy, Sembcorp Green Hydrogen, and ReNew E-Fuels.

Adani Total Gas Ltd will blend green hydrogen with natural gas for over 4,000 home and commercial piped natural gas (PNG) customers during the pilot phase. The project will assess the viability of green hydrogen as an alternative energy source for city gas distribution (CGD) consumers.

Swedish battery maker Northvolt has developed its first sodium-ion battery in partnership with Uppsala University spinoff Altris. The cell has been validated for an energy density of more than 160 Wh/kg and is designed primarily for energy storage applications.

Germany, in collaboration with Italy, has revealed plans to import hydrogen from Northern Africa.

The oil and natural gas major will make a capital investment of INR 75,000 crore over the next five years with up to 30% of the amount going into the renewables and gas segment.

An international research group has utilized a new porosification technique to build gallium arsenide (GaAs) solar cells that allow the recovery of germanium films. The new cell achieved an efficiency that is reportedly in line with that of other GaAs PV devices, but can be produced at a lower cost thanks to the reuse of germanium.

Statkraft used actual production data from wind and solar farms in Spain to study the feasibility and bankability of hydrogen projects. For a 1 MW electrolyzer to achieve a 40% utilization rate, five times more solar capacity would be needed, it said.

Achieved by scientists led by the National University of Singapore, the result is the highest efficiency ever recorded for a perovskite-CIS tandem solar cell at the research level to date. The researchers used methyldiammonium diiodide (MDADI) to reduce open-circuit voltage losses in the top perovskite cell.

Schneider Electric’s state-of-the-art battery lab will focus on developing innovative battery technologies and exploring new energy storage solutions that prioritize sustainability and minimize environmental impact.
