Biofuels
Could biofuels make low-emission flying a reality? Biofuels produce 70-90% less carbon than conventional jet-fuel. The problem is still the price; it’s 3-4 times more expensive. But economies of scale and policy incentives can fix this. Land-use competition with food is another concern, but there are alternatives like algae-based biofuels. Even better, Virgin Atlantic flew the first waste-based biofuels commercial flight in 2018. Now Velocys is building a waste-to-biofuels energy plant in the UK. Add natural climate solutions (i.e. investing in biocapacity) and a net-zero or net-positive carbon footprint looks possible. Is an end to flight-shame on the horizon?
