Abstract

SANDOVAL, J. A.  and  CASTIBLANCO, O.. Review of the potential for obtaining biohydrogen from microalgae in Colombia. Entre Ciencia e Ingenieria [online]. 2022, vol.16, n.32, pp.9-15.  Epub July 12, 2023. ISSN 1909-8367.  https://doi.org/10.31908/19098367.2798.

Hydrogen is an essential energy vector considering a transition to a decarbonized system and microalgae are one of the most promising resources for its production. The aim of this work is to review studies related to the production of biohydrogen by means of microalgae to determine and evaluate the different production methods and those factors that affect them, as well as their limitations, considering research carried out all over the world and especially in Colombia. The results have shown that dark fermentation has several advantages compared to other methods, it does not demand large growing spaces, hydrogen is produced at a high rate and with high efficiency, and valuable by-products can be obtained. This makes biohydrogen an attractive energy alternative for the country.

Keywords : Biofuels; biophotolysis; dark fermentation; hydrogen; microalgae.
