Riversimple, a small independent car manufacturer in rural Wales, is taking a bet that hydrogen vehicles will play a key part in the future of transport.
Former auto engineer Hugo Spowers swore off working with petrol engines 15 years ago when he began toying with the idea of building hydrogen-powered vehicles.
Spowers was determined to devise a fundamentally new solution to address the problems associated with carbon emissions.
“We’ve got to move beyond trying to make combustion engines a little bit less bad,” he tells CNN. “Because after all, being a little bit less unsustainable is still not sustainable.”
