Green Hydrogen: Mission, Refineries and the Train
Green hydrogen — split out of water with renewable power, leaving only water behind — is India's chosen fix for industries that batteries cannot reach, and the National Green Hydrogen Mission is now turning its Rs 19,744 crore into firm orders: 30 KTPA of refinery capacity allotted in August 2026, and the country's first hydrogen fuel-cell train in service since July 2026. A Bengaluru laboratory has meanwhile shown a metal-free organic catalyst that splits water using nothing but sunlight.

Added a research front to the card. Scientists at the Centre for Nano and Soft Matter Sciences in Bengaluru, an institute of the Department of Science and Technology, have built a photocatalyst with no metal in it: an amino acid joined to a light-absorbing dye, the pair assembling itself in water into ordered nanosheets that split water using sunlight. The ordered form yields nearly 18 percent more photocurrent than the same material in bulk. Mission outlay, targets, the refinery allocations and the hydrogen train are unchanged.
