While having been recently more focused on electric aviation for small airplanes, Airbus has now pivoted towards hydrogen as a candidate for solving aviation’s CO2 problems.“Our experience with batteries shows us that battery technology is not moving at the pace we want,” says Glenn Llewellyn, vice president of zero emission aircraft at Airbus. “This is where hydrogen comes in, it’s got several thousand times more energy per kilogram than what batteries could have today.”Llewellyn says Airbus has already started talking hydrogen with airlines, energy companies and with airports, because “this kind of change really requires a teaming across industry and inside the aviation industry in order to make it happen.”Hydrogen has long been seen as a viable fuel by academics, but until now it’s had little practical support.Perhaps now, with batteries not quite cutting it, hydrogen’s time has come.
