“…Biological hydrogen production using microalgae can be done either by bio-photolysis, where microalgae act as a biocatalyst, or fermentation, where algal biomass is utilized as feedstocks [109]. Biophotolysis can be categorized as direct and indirect, whereas fermentation can be classified as photo-and dark fermentation [123].…”

Globally, nations are trying to address environmental issues such as global warming and climate change, along with the burden of declining fossil fuel reserves. Furthermore, countries aim to reach zero carbon emissions within the existing and rising global energy crisis. Therefore, bio-based alternative sustainable feedstocks are being explored for producing bioenergy. One such renewable energy resource is microalgae; these are photosynthetic microorganisms that grow on non-arable land, in extreme climatic conditions, and have the ability to thrive even in sea and wastewater. Microalgae have high photosynthetic efficiencies and biomass productivity compared to other terrestrial plants. Whole microalgae biomass or their extracted metabolites can be converted to various biofuels such as bioethanol, biodiesel, biocrude oil, pyrolytic bio-oil, biomethane, biohydrogen, and bio jet fuel. However, several challenges still exist before faster and broader commercial application of microalgae as a sustainable bioenergy feedstock for biofuel production. Selection of appropriate microalgal strains, development of biomass pre-concentrating techniques, and utilization of wet microalgal biomass for biofuel production, coupled with an integrated biorefinery approach for producing value-added products, could improve the environmental sustainability and economic viability of microalgal biofuel. This article will review the current status of research on microalgal biofuels and their future perspective.

“…In comparison to traditional energy sources such as fossil fuels, hydrogen (H 2 ) is a promising future clean energy carrier because of its calorific value (142 kJ g −1 ) and the combustion product being water rather than greenhouse gases [187]. Microalgal hydrogen production can be categorized into bio-photolysis and fermentation processes [188]. Dark fermentation (DF) is well known for the fermentative conversion of algal biomass to molecular H 2 by a diverse group of anaerobic bacteria.…”

“…Moreover, photolysis can be divided into direct and indirect photolysis. In direct photolysis, H 2 O is split directly into H 2 and O 2 in a single stage (H 2 O is split into H+ and electrons (and O 2 ), and electrons are transferred to hydrogenase, which catalyzes the H 2 formation), whereas in indirect photolysis, CO 2 is fixed by algae for carbohydrate biosynthesis (first stage) and further fermenting of the carbohydrate to produce hydrogen with the help of hydrogen-producing enzymes (second stage) [188]. Microalgae involved in photolysis are Platymonas subcordiformis, Chlorococcum littorale, marine Anabaena sp., and Synechococcus sp.…”

“…As a result, improving hydrogen generation using microalgal cells is a challenging task. Furthermore, since the maturation of NiFe-hydrogenases needs a large number of specialized maturation enzymes, the heterologous production of O 2 -tolerant hydrogenases in cyanobacteria is difficult [188]. Moreover, the development of an appropriate photobioreactor for large-scale H 2 production through photolysis is challenging [188].…”

Whole-cell microalgae biomass and their specific metabolites are excellent sources of renewable and alternative feedstock for various products. In most cases, the content and quality of whole-cell biomass or specific microalgal metabolites could be produced by both fresh and marine microalgae strains. However, a large water footprint for freshwater microalgae strain is a big concern, especially if the biomass is intended for non-food applications. Therefore, if any marine microalgae could produce biomass of desired quality, it would have a competitive edge over freshwater microalgae. Apart from biofuels, recently, microalgal biomass has gained considerable attention as food ingredients for both humans and animals and feedstock for different bulk chemicals. In this regard, several technologies are being developed to utilize marine microalgae in the production of food, feed, and biofuels. Nevertheless, the production of suitable and cheap biomass feedstock using marine microalgae has faced several challenges associated with cultivation and downstream processing. This review will explore the potential pathways, associated challenges, and future directions of developing marine microalgae biomass-based food, feed, and fuels (3F).
