KEY POINTS

Hydrogen Fuel Cell

Hydrogen fuel cell works much like an electric battery, converting chemical energy into electrical energy using the movement of charged hydrogen ions across an electrolyte membrane to generate current.

Feasibility in Capital region

·        Fuel cells have strong advantages over conventional combustion-based technologies, given that they produce much smaller quantities of greenhouse gases and none of the air pollutants that cause health problems.

·        Also, if pure hydrogen is used, fuel cells emit only heat and water as a byproduct. Such cells are also far more energy efficient than traditional combustion technologies.

·        Unlike battery-powered electric vehicles, fuel cell vehicles do not need to be plugged in, and most models exceed 300 km of range on a full tank. They are filled up with a nozzle, just like in a petrol or diesel station.

Challenges

·        While hydrogen based EVs do not generate gases that contribute to global warming, the process of making hydrogen needs energy — often from fossil fuel sources. That has raised questions over hydrogen’s green credentials.

·        Also, there are questions of safety — hydrogen is more explosive than petrol.

·        The other major hurdle is that the vehicles are expensive, and fuel dispensing pumps are scarce. But this should get better as scale and distribution improves.

Progress in India

·        In India, so far, the definition of EV only covers BEVs; the government has lowered taxes to 12%. At 43%, hybrid electric vehicles and hydrogen FCEVs attract the same tax as IC vehicles.

·        The Ministry of New and Renewable Energy, under its Research, Development and Demonstration (RD&D) programme, has been supporting various such projects in academic institutions, research and development organisations and industry for development.

·        The Ministry of Science and Technology has supported two networked centres on hydrogen storage led by IIT Bombay and Nonferrous Materials Technology Development Centre, Hyderabad. These involve 10 institutions, including IITs, and IISc, Bangalore.

Working of Hydrogen fuel is not needed. HFC in vehicular pollution is also not needed. Try to elaborate more on feasibility. Keep Writing.
