How sustainable is aviation fuel by 2050?

Sustainable aviation fuel prices in 2050 will remain two to four times higher than the historical average of jet fuel. Hydrogen and electric propulsion will reduce less than 5% of 2050 aviation emissions, given the time required for the technologies to mature.
