Paul Eremenko, co-founder and CEO of Universal Hydrogen, believes that there is a relatively simple way to solve the aviation industry’s carbon emissions problem. Today’s sustainable fuels aren’t really all that sustainable, he says, and electric planes, while great in theory, don’t scale. That leaves one obvious choice for Eremenko: green hydrogen. “There is a very significant sort of low-hanging fruit opportunity with no significant tech risk to put hydrogen in service and solve in one fell swoop half of aviation emissions problems by 2035,” Eremenko says.
