In theory, a hydrogen car could be the ideal compromise between a petrol and an electric car. It's better for the environment and cheaper to run than a petrol (or diesel) car, while it's also similar to an electric car in the way it drives (with effortless acceleration, brake regeneration and impressive refinement). Hydrogen cars can also travel further between top-ups than battery-electric vehicles, while refuelling a hydrogen car takes a matter of minutes.

The problem with hydrogen is it's expensive to produce and the infrastructure for refuelling hydrogen cars simply isn't there (there are currently around 16 hydrogen filling stations in the UK). There are very few hydrogen cars on the market and, as we're now so far down the path of pure-electric vehicles, it's unlikely we will see a seismic shift towards hydrogen power in the near future at least.
