What happened to hydrogen? I am sure I watched James May drive around in a Hydrogen powered Honda in the US a few years ago.
If done correctly all that comes out of the exhaust is steam. As much as I think electric cars are great for short trips I think there use is limited, no chance of covering long distances without long stops and can you really see HGV's and other commercial vehicles running on batteries? Some commercial vehicles get very little down time apart from driver turn round so wont have time for several hours of recharging. I know of one HGV Tractor unit that has covered near on half a million miles in 4 years. I know TNT trialled a 7.5 Tonne truck in Oxford that was battery powered, it was returned to the supplier after a short period due to its poor range and it only had to go from Dicot to Oxford. |

Commercially hydrogen is formed by stripping the carbon atoms from hydrocarbons - so gas / oil is broken to hydrogen and carbon so you still let the carbon run free in the form of c02. Plus the trouble of storage etc.
Hydrolysing water is inefficient so technically using the leccy straight into a battery works with fewer losses. Personally though I think hydrogen is a winner, you need to sort the leccy generation and storage out. Nuclear and all the renewables to keep greens happy then use the stored hydrogen to smooth the grid. |
