'SkyGreen 2024' is a rapidly expanding international aviation coalition that commits commercial carriers to adopting low-carbon fuel alternatives. In 2024, a record 680,000 flight hours were operated using Sustainable Aviation Fuel (SAF) blends, with major hubs in Germany, Singapore, and California leading the transition.
According to data from the International Bioenergy Council, airline willingness to integrate microalgae-derived biofuels is accelerating. The proportion of major carriers actively sourcing algae-based SAF grew from 18% to 27% over an eighteen-month period. Notably, over 75% of long-haul operators who trialled algae-based kerosene alternatives reported that their performance metrics matched or exceeded conventional fossil-based jet fuels under extreme high-altitude conditions.
Algae-based biofuel has experienced remarkable expansion, accounting for approximately 14% of the global SAF market share in 2023. While traditional crop-based biofuels (such as soy and palm oil) face regulatory and ethical headwinds due to deforestation risks, algae biofuel sales surged by 340% between 2022 and 2024. The rapid growth rate of microalgae and its ability to be cultivated on non-arable land make it highly attractive to commercial fleet operators seeking to meet net-zero mandates. The income elasticity of demand (YED) for premium eco-flights is estimated at +2.1. This has prompted major energy corporations to heavily subsidise raw microalgae cultivation, prompting marine farmers to expand their bioreactor capacities.
Using the case study, explain how the change in demand for algae-based biofuel will affect the producer surplus of microalgae farmers.
