Abstract

A simple model of the world air market is used to test the role that liquid hydrogen (LH2) aircraft might play in reducing carbon dioxide (CO2) emissions from this sector of the economy. I assume that LH2 aircraft can penetrate up to 70% of the market and will do so along a logistic diffusion curve with Δt = 40 yrs. Using two scenarios—high and low demand—I find that although LH2 aircraft and the LH2 supply system can be configured to release no CO2, the remaining conventional aircraft in the market continue to play a large role in the total sector CO2 emissions. The model is very sensitive to the balance between the LH2 substitution effect, market growth, and efficiency growth. Liquid hydrogen aircraft can help reduce CO2 emissions, but reducing CO2 emissions below current levels will also require constraints on growth in the entire air market.
