India Advances Green Energy with Solar-Powered Hydrogen Device
Scientists in India have created a new device that can make clean fuel (green hydrogen) using only sunlight.
This device splits water into hydrogen and oxygen using a special process.
While it's exciting, experts say it needs more testing and support to be widely used.
The government has a plan to boost green hydrogen, and the railway is also testing hydrogen-powered trains.
It shows great promise for cleaner energy in the future.
A solar-powered device developed in India can produce green hydrogen using solar energy.
The device uses a photoelectrochemical (PEC) process to split water molecules with sunlight.
Experts highlight the need for pilot projects, low-cost catalysts, and collaboration for broader impact.
India launched the National Green Hydrogen Mission in January 2023 with a large financial outlay.
The Indian Railways successfully tested the first hydrogen-powered coach in Chennai.
