Does hydrogen have a role to play in a clean-energy future?
Over the past year, hydrogen has re-emerged as one of the most promising
answers. Mostly because it’s such a versatile fuel, but also because
the cost of producing “green” hydrogen using renewable electricity or
other low-carbon processes is rapidly falling. Our cars, buses and
delivery vans may be going battery-electric, and batteries may be a big
part of the answer to energy storage on the electrical grid. But green
hydrogen, according to the International Energy Agency, offers what
batteries can’t – a flexible way to decarbonize ships, trains, and big
airplanes, displace the use of natural gas for heating, and replace
fossil fuels used by heavy industry.
