520 3 _aOne of the biggest challenges for hydrogen (H2) production via biophotolysis is the sensitivity of the process to oxygen (O2), which is the primary inhibitor of the hydrogenase enzyme responsible for H2 production. The present study reviews the literature on methods to enhance H2 production by creating suitable conditions to enable the activity of the hydrogenase enzyme. Techniques studied include the regulation of available O2 and utilizations of antioxidants. Furthermore, optimizing algal growth parameters such as pH, temperature, light intensity, and cell density can keep the algal cells alive for a more extended period for biophotolysis and can directly or indirectly activate enzymatic activity for enhanced H2 production. Various O2 regulating techniques, i.e., mineral deprivation, oxygen-reducing agents/scavengers, co-culturing of microalgae with bacteria, the addition of antioxidants and nanoparticles have been analyzed and discussed in this review. Analysis of strengths, weaknesses, opportunities, and threats/challenges (SWOT) also presents the limitations and advantages of H2 production via biophotolysis. This review insights that employing all the favorable techniques with suitable operating parameters simultaneously can result in enhanced H2 yield and better process sustainability. However, O2 regulating techniques such as co-culturing with bacteria and the use of antioxidants/nanoparticles appear to be the most significant in H2 production via biophotolysis towards environmental sustainability and green energy.
