Algae and aquatic biomass production systems
Sustainable Aviation Fuels from Algae: The Search for Economically Viable Scaling
Short Introductive summary
A techno-economic analysis is being conducted to explore the production of sustainable aviation fuels (SAFs) from algae via hydrothermal liquefaction (HTL). This analysis identifies key factors influencing production costs, including biocrude yield, feedstock costs, and plant scale. Although in the literature costs vary considerably (12–396 EUR/GJ), large-scale production is expected to reduce costs to a level similar to that of fossil fuels. The study’s findings suggest that this production method is economically feasible through the use of dedicated plants and optimised processes, although the transition to large-scale production is a significant challenge.
