Ya me leí dos de los estudios y, el de estos asiáticos está muy bueno:
https://www.researchgate.net/publication/314105179_Hydrothermal_Liquefaction_HTL_A_Promising_Pathway_for_Biorefinery_of_AlgaeReconocen que, el proceso de HTL (hydrothermal liquefaction) deja
un montón de NITROGENO en el líquido resultante y eso es contaminante y afecta el producto de varios modos.
Nitrogen content in biocrude can impact the properties (Gupta and Demirbas2010), like smell and combustion. Nitrogen in proteins is main contributor for that in biocrude, which will be decomposed and reformed via HTL (Yu et al. 2011b).The high nitrogen content of the biocrude is therefore considered as one of bottlenecks hindering the development of algae HTL to produce transportation fuel (Gupta and Demirbas 2010; Ramirez et al. 2015; Zhu et al. 2013).
Pero, lo que más me interesa es que tienen la HONESTIDAD de reconocer que
NO ES ECONOMICAMENTE VIABLE producir biocombustibles de algas SALVO que se produzcan "otras cosas" (y ya entramos con los usos en perfumería, medicamentos, y demás).

Leamos a los investigadores:
So far, the “only biofuel” option is unlikely to be economically viable for algae biomass (Williams and Laurens 2010). Other chemicals can also be produced either from HTL or other process. It might also be possible to extract value-added chemicals from biocrude since it is complex and contains different cyclicnitrogenates and oxygenates besides hydrocarbon (Ramirez et al. 2015).
Que, traducido viene a decir:
