“…Cyanobacteria are classified into three categories (e.g., unicellular, filamentous, and colonial species) on the basis of their morphology . Recently, the unicellular green algae Chlamydomonas reinhardtii has gained significant attention in the generation of hydrogen molecules by direct biophotolysis. , In direct biophotolysis, water molecules are split into protons (H + ) and oxygen through photosystem II (PS II) using the captured photons from light energy.…”

Clean and green energy has become very much desirable in recent times to mitigate the environmental problem associated with fossil fuels. Hydrogen can be utilized as sustainable energy resources whenever it is produced via green routes. Hydrogen production using solar energy is a pollution-free route as the carbon footprint is zero or significantly less than other hydrogen-generation methods. This review elucidates various hydrogen-generation routes using solar energy as the primary energy resource. Both thermal and photoassisted routes are incorporated in this review. It is found that solar photovoltaic cell associated with water electrolyzer is very popular. Biomass can also be converted to hydrogen through thermal and photoassisted processes. The economic analysis confirmed that hydrogen-fueled cars are economical as well as environmentally friendly.

“…Several microalgae species have been studied for H 2 production, especially C. reinhardtii, Chlorella vulgaris, and Chlorella pyrenoidosa [10][11][12][13]. Among them, C. reinhardtii is a model microorganism widely recognized as an H 2 producer, presenting a hydrogenase with an enzymatic activity 10 to 100 times higher than other species [14].…”

It is well known that over the last 60 years the trend of long-lived greenhouse gas emissions have shown a strong acceleration. There is an increasing concern and a mounting opposition by public opinion to continue with the use of fossil energy. Western countries are presently involved in a so-called energy transition with the objective of abandoning fossil energy for renewable sources. In this connection, hydrogen can play a central role. One of the sustainable ways to produce hydrogen is the use of microalgae which possess two important natural catalysts: photosystem II and hydrogenase, used to split water and to combine protons and electrons to generate gaseous hydrogen, respectively. For about 20 years of study on photobiological hydrogen production, our scientific hopes were based on the application of the sulfur protocol, which indisputably represented a very important advancement in the field of hydrogen production biotechnology. However, as reported in this review, there is increasing evidence that this strategy is not economically viable. Therefore, a change of paradigm for the photobiological production of hydrogen based on microalgae seems mandatory. This review points out that an increasing number of microalgal strains other than Chlamydomonas reinhardtii are being tested and are able to produce sustainable amount of hydrogen without nutrient starvation and to fulfill this goal including the application of co-cultures.
