There are ways to create biofuels that are much more environmentally friendly than hydrocarbon fuels, especially when starting from a waste product such as cooking oil or biomass from clearings that would otherwise be wasted.
Plus, it’s good to test out these not-yet-incredible sustainable fuels so that we can learn, improve, and wean off traditional hydrocarbon fuels.
While making it out of existing carbon compounds, of course, removes much of the energy needed, it is still a wasteful process. There are plenty of precesses where you can burn that fuel directly, with zero additional loses. We need to drive CO2 emissions down as fast as possible.
This is something that can be tackled in 30 years, when/if airplanes still need to burn fuel and other, lower hanging fruits are already gone.
What they are actually doing is trying to greewash airplanes.
