NTPC Ltd has invited Global Expression of Interest to provide 10 Hydrogen Fuel Cell-based electric buses and cars.
About:
A fuel cell is a device that converts chemical potential energy (energy stored in molecular bonds) into electrical energy.
A PEM (Proton Exchange Membrane) cell uses hydrogen gas (H2 ) and oxygen gas (O2 ) as fuel. The products of the reaction in the cell are water, electricity, and heat.
Hydrogen + Oxygen -> Electricity + Water Vapour
This is a big improvement over internal combustion engines, coal-burning power plants, and nuclear power plants, all of which produce harmful by-products.
Since O2 is readily available in the atmosphere, we only need to supply the fuel cell with H2 which can come from an electrolysis process
What is Hydrogen?
Hydrogen is the simplest element. An atom of hydrogen consists of only one proton and one electron.
It’s also the most plentiful element in the universe. Despite its simplicity and abundance, hydrogen doesn’t occur naturally as a gas on Earth – it’s always combined with other elements.
Water, for example, is a combination of hydrogen and oxygen (H2 O).
Hydrogen is high in energy, yet an engine that burns pure hydrogen produces almost no pollution.
NASA has used liquid hydrogen since the 1970s to propel the space shuttle and other rockets into orbit.
Hydrogen fuel cells power the shuttle’s electrical systems, producing a clean byproduct – pure water, which the crew drinks.
