The market development of aviation biofuel: drivers and constraints

BAF has not been receiving sufficient investments due to inadequate government support and industry commitment, unreliable supply of feedstocks, uncertain commerciality of the production pathways, and lack of supply chain certification.

“It has not been receiving sufficient investments due to inadequate government support and industry commitment, unreliable supply of feedstocks, uncertain commerciality of the production pathways, and lack of supply chain certification (Gegg et al. 2014).”

Bio-aviation fuel has less risk in the long term in the case of fuel spillage.

Bio-aviation fuel production is associated with problems of monocultures, such as lack of biodiversity and susceptibility to pests.

“Problems associated with monocultures, e.g.lack of biodiversity and susceptibility to pests.”

Bio-aviation fuel has a theoretically unlimited feedstock supply.

Bio-aviation fuel production competes with food supply if energy crops become more profitable than food crops for farmers.

Bio-aviation fuel is capable of reduced net CO2 emissions when burned, depending on production methods.

Bio-aviation fuel feedstocks have spatial and temporal boundaries, e.g., they may not be grown all year round or at all in some areas if specific conditions are required.

Bio-aviation fuel can be used as a 'drop-in' alternative for existing engines.

Bio-aviation fuel production causes detrimental land-use change, such as clearing existing vegetation, eutrophication from fertiliser use, and water/energy use during cultivation.

“Detrimental land-use change, e.g.clearing existing vegetation from land, eutrophication from fertiliser use, and water/energy use during cultivation.”

Bio-aviation fuel is generally lower in contaminants, e.g., sulphur.
