The government has set ambitious targets to reduce carbon emissions by 46% from 2013 levels by 2030 and achieve carbon neutrality by 2050. Transitioning to hydrogen-powered rail transport is a critical part of this strategy, especially given the country’s extensive rail network, which carries millions of passengers daily.

How the Hydrogen-Powered Train Works

The train operates using hydrogen fuel cells, which convert hydrogen gas into electricity to power electric motors. This electricity propels the train, allowing it to operate without the need for traditional diesel engines or external power lines. The only emission produced during this process is water vapor, making it an environmentally friendly alternative to conventional trains.

Hydrogen is stored in high-pressure tanks onboard the train, and advanced fuel cell systems regulate the flow of hydrogen to generate electricity efficiently. The train’s design also incorporates energy recovery systems, which capture and reuse energy generated during braking, further improving efficiency and reducing energy waste.
