What is special about the 'green hydrogen vessel' made in Kochi, launched by Modi?

Launching India's first indigenous green hydrogen waterway vessel in Tamil Nadu's Thoothukudi on Wednesday, PM Modi stated something that Kerala can be proud of.  He said that the country's mission towards clean, hydrogen fuel-based transport is strengthened by Kerala's own Cochin Shipyard. The green fuel-efficient transport ferry, put together at the Shipyard, has many unique features. Here are a few of them: 

Size, capacity and emissions
The 24-metre-long catamaran can hold 50 passengers. It is a 'clean transportation' mode with zero greenhouse gas emissions. It has quieter movements and lower lifetime operation costs, according to the PM's YouTube channel. He said that the vessel will also be deployed soon in Varanasi. 

Green hydrogen as a maritime fuel
As per reports, India's commitment towards a sustainable future aims for net zero emissions by 2070. The adoption of green hydrogen as a maritime fuel is at the forefront of this mission. The VO Chidambaranar Port in Thoothukudi will soon become the country's first hydrogen hub port as well.
