In the search of alternative routes for energy, microalgal hydrogen
production becomes an important topic as a renewable and sustainable candidate.
Following the progresses in the knowledge related with cellular mechanisms and
production processes, biohydrogen can have the chance to take a strong role in the
future even if the current capacities are not comparable to the conventional fossil fuels.
This chapter focuses on the state of the art for biohydrogen production from
microalgae.
Keywords: Biohydrogen, Microalgae, Photobioreactor, Economy.
