IF YOU look very, very hard on the roads of Scotland, you won’t see many hydrogen refuelling stations.
Yet car manufacturers are investing billions in developing new cars, vans and lorries that can use this green source of fuel.
What do they know that we don’t?
Firstly, they know that hydrogen is clean. You can make it from renewably generated electricity, something we produce a lot of in Scotland.
I learned that, at times, 60 per cent of Scotland’s national electricity needs come from renewable sources such as solar panels and wind turbines.
