“…Then it produces adenosine triphosphate (ATP) and reduces the ferredoxin compound. These take part in various metabolic reactions to produce hydrogen (Razu et al, 2019). The biophotolysis process is divided into two categories: indirect and direct biophotolysis.…”

“…The indirect method is not continuous as a return of the light period makes the growth become photosynthetic and hinders H 2 ase (El-Dalatony et al, 2020). Indirect biophotolysis is a two-step process: i) the first stage involves oxygen producing and carbon dioxide fixing into chemical energy carbohydrates, and lipids; and ii) the second stage is functionally the same and a small sealed photo-bioreactor is used with CO 2 synthesis which is divided periodically in the absence of light exposure (Razu et al, 2019).…”

“…The electron is then transferred to [FeeFe]-hydrogenases resulting in biohydrogen production (Lam and Lee, 2013). This hydrogen production method using biological photolysis was first trialled on a nonheterocystous microalga such as cyanobacteria Plectonemaboryanum which was subjected to frequent cycles of "aerobic light-driven CO 2 fixation and O 2 " (Razu et al, 2019). The reactions to this process are as follows (Sharma and Arya, 2017):…”

“…Nevertheless, difficulties in process engineering, low productivity of microalgae, oxygen sensitivity, and operational costs, and inadequate insights on strain capacity, hinder the commercialization of microalgae-based biohydrogen production. Even though there are several metabolic routes to produce biohydrogen from microalgae with an improved yield, recent reviews (Buitrón et al, 2017;Sharma and Arya, 2017;Shobana et al, 2017;Show et al, 2018;Razu et al, 2019;Show et al, 2019b;El-Dalatony et al, 2020;Jiménez-Llanos et al, 2020;Mona et al, 2020;Salakkam et al, 2021) have not provided the comprehensive economic evaluation of such strategies, which has resulted in a dearth in the understanding of process feasibility. Therefore, in addressing this knowledge gap, this mini-review explicates the metabolic routes that enhance microalgae-based biohydrogen production and provides insights into their economic considerations to guide future work in the scaling-up of these technologies.…”

The commercialization of hydrogen as a fuel faces severe technological, economic, and environmental challenges. As a method to overcome these challenges, microalgal biohydrogen production has become the subject of growing research interest. Microalgal biohydrogen can be produced through different metabolic routes, the economic considerations of which are largely missing from recent reviews. Thus, this review briefly explains the techniques and economics associated with enhancing microalgae-based biohydrogen production. The cost of producing biohydrogen has been estimated to be between $10 GJ-1 and $20 GJ−1, which is not competitive with gasoline ($0.33 GJ−1). Even though direct biophotolysis has a sunlight conversion efficiency of over 80%, its productivity is sensitive to oxygen and sunlight availability. While the electrochemical processes produce the highest biohydrogen (>90%), fermentation and photobiological processes are more environmentally sustainable. Studies have revealed that the cost of producing biohydrogen is quite high, ranging between $2.13 kg−1 and 7.24 kg−1via direct biophotolysis, $1.42kg−1 through indirect biophotolysis, and between $7.54 kg−1 and 7.61 kg−1via fermentation. Therefore, low-cost hydrogen production technologies need to be developed to ensure long-term sustainability which requires the optimization of critical experimental parameters, microalgal metabolic engineering, and genetic modification.

“…Besides, it has a higher energy density than other hydrocarbon fuels (Oey et al, 2016). Microalgae can produce hydrogen through bio-photolysis or photo-fermentation (Razu et al, 2019). Hydrogen (H2) is becoming increasingly important as a CO2-free fuel that can be harnessed to power the coming generation of H2 fuel cells through various renewable technologies e.g., photovoltaic (PV), wind, and biological systems such as microalgae (Oey et al, 2016).…”

The world’s energy needs highly depend on fossil fuels, which were formed over several million centuries. The price of petroleum increases daily and unfortunately, its exploitation is currently at an alarming rate for such essential non-renewable energy. Also, the recent clamour for safe and cheap alternative means of energy generation to mitigate global warming and its detrimental effects is drawing attention towards biofuel production to supplement and possibly, substitute fossil fuels. To this effect, many plant materials have been tested and employed in the past decades for biofuel production. However, a good number of plants used in biofuel production as feedstock are crop plants, which have more economic value as food. Therefore, it is imperative to explore the possibility of biofuel production from non-food sources, hence, we examine the potential of microalgae as an alternative source of renewable energy. Microalgae are of great interest in biofuel production for its high productivity, cosmopolitan nature, easy culturing on waters and land, and noncompeting with conventional agriculture for resources. In view of these, this article focuses on the potentials of microalgae in biofuel production and mitigation of environmental pollution by its considerably low greenhouse gas emissions.
