New hydrogen- and electric-powered aircraft expected to enter service could require as much as 600 to 1,700 terawatt-hours of energy by 2050, which the World Economic Forum (WEF) says is equivalent to the energy generated by up to 25 of the world’s largest wind farms today—or a solar farm large enough to cover half of Belgium. In a new white paper, the organization spells out what airlines and airports will need to do to ensure that the new means of net-zero carbon propulsion are viable.
In short: it’s not going to come cheap. According to David Hyde, the WEF’s aerospace projects lead, the industry will need to invest between $700 billion and $1.7 trillion by 2050. About 90 percent of this investment will be for off-airport infrastructure, primarily power generation and hydrogen electrolysis and liquefaction.
