Are hydrogen-fuelled planes a route to cleaner air travel?

They don’t emit any harmful greenhouse gases – just water.

The British government believes hydrogen is key to decarbonising the aviation industry and investors are lining up to back the idea.

So could hydrogen-electric planes be the way to cleaner, greener air travel?
