According to the study, hydrogen may meet 30 per cent of energy needs by 2050.
Hydrogen is expensive and the cost of building, and then later upgrading, power plants to burn a fuel which isn’t yet widely available is also high. Hydrogen’s potential has been downgraded in recent years after being initially touted as the fuel of the future, powering planes, trains and automobiles and heating homes
The hydrogen-powered trains have a "range of 1,000 kilometres", can clock a top speed of "140 kph" and are "emission free in operation", French company Alstom, which manufactured the trains, has said
Though these are early days for hydrogen’s application as an energy source, both in India and globally, the fact that global energy players have formed a consortium to collectively pool their resources suggests an acceleration in its adoption
