Abstract

AbstractA preliminary techno‐economic assessment of a microalgae biorefinery plant is reported, with pulsed electric field treatment (PEF) hydrothermal liquefaction as core technology. The results indicate that standalone production of microalgae biofuel would lead to an annual loss of 2.615 M€. PEF treatment could improve this scenario by bringing the microalgae biofuel to a competitive level (0.78 € kg−1). Assuming that microalgae biofuel would be sold at the price of crude oil (0.44 € kg−1), the minimum price of the amino‐acid based product should be 7.56 € L−1 for positive capital returns.
