I read an article on this. Appears there are 3 reasons it hasn't caught on.
1 - If it is grey, it pollutes. If it is not produced using renewable sources, hydrogen pollutes. To date, more than 96% of the hydrogen used is grey. (The biggest challenge is to produce clean hydrogen at an affordable cost,)
2 - Hydrogen is a difficult gas to handle because, having a low volumetric energy density, it has to be highly compressed at high pressures (from 350 to 700 bar) to be packed into a tank in sufficient quantities to power a car. Another difficulty lies in transport, in other words, how to carry hydrogen to the refueling stations to supply traveling cars.
3 - The battery-powered electric motor is now the most efficient system because it converts 80% of the electricity in the battery into energy. What’s more, it is currently cheaper to charge an electric car than to refill on hydrogen. |
