There is a number of processes involving supercritical fluids (SCF) whereby different biofuels can be produced. On many occasions, supercritical processes can also produce heat and electricity along with biofuels. However, large-scale implementation of supercritical processes mainly depends on the economic competitiveness of biofuels production compared with those fuels produced from conventional fossil sources. Since the technology to produce biofuels based on SCF has not yet been commercialized, the techno-economic assessment (TEA) is a valuable tool to make a decision about a future commercial development, since it allows assessing the potential economic feasibility and the possible technical alternatives to improve the process. This short review provides a techno-economic procedure to apply to any production process biofuel under supercritical conditions and includes a discussion on several supercritical processes where a few economic indicators are used in the analysis of the process feasibility.

有许多涉及超临界流体（SCF）的过程，因此可以生产不同的生物燃料。在许多情况下，超临界过程还可以与生物燃料一起产生热量和电能。然而，超临界过程的大规模实施主要取决于生物燃料生产与传统化石资源生产的燃料相比的经济竞争力。由于基于SCF的生物燃料生产技术尚未商业化，技术经济评估（TEA）是决定未来商业发展的宝贵工具，因为它可以评估潜在的经济可行性和可能的​​技术替代方案改善流程。
