Hydrogen is the most abundant gas in the Universe, and hydrogen-powered cars only emit water vapor. In principle, therefore, hydrogen could be a cheaper and cleaner fuel for our cars. But hydrogen remains too dangerous in its liquid form to take onboard enough fuel for a long journey. And so the race is on to find a way to store hydrogen at greater densities and at lower pressures.
