Hydrogen Hype is Back! Should we believe it this time?

Hydrogen-powered vehicles are back in the headlines, with major manufacturers including JCB, Volvo, Mercedes-Benz and Toyota investing in new hydrogen technologies. But while battery-electric vehicle sales continue to grow, hydrogen transport remains stubbornly uncompetitive. With insights from energy experts Paul Martin and Michael Barnard, we examine the physics, economics, environmental impacts and infrastructure challenges behind hydrogen fuel cells and combustion engines — and ask why governments and industry are still pouring billions into a technology that struggles to compete with direct electrification.
