There　has　been　an　urgent　need　to　tackle　global　climate　change　and　replace　conventional　fuels　with　alternatives　from　sustainable　sources.　This　has　led　to　the　emergence　of　bioenergy　sources　like　biofuels　and　biohydrogen　extracted　from　microalgae　biomass.　Microalgae　takes　up　carbon　dioxide　and　absorbs　sunlight,　as　part　of　its　photosynthesis　process,　for　growth　and　producing　useful　compounds　for　renewable　energy.　While,　the　developments　in　artificial　photosynthesis　to　a　chemical　process　that　biomimics　the　natural　photosynthesis　process　to　fix　CO2　in　the　air.　However,　the　artificial　photosynthesis　technology　is　still　being　investigated　for　its　implementation　in　large　scale　production.　Microalgae　photosynthesis　can　provide　the　same　advantages　as　artificial　photosynthesis,　along　with　the　prospect　of　having　final　microalgae　products　suitable　for　various　application.　There　are　significant　potential　to　adapt　either　microalgae　photosynthesis　or　artificial　photosynthesis　to　reduce　the　CO2　in　the　climate　and　contribute　to　a　cleaner　and　green　cultivation　method.　©　2022
