Environmental Assessment of Microalgal Biomass Fermentation for Green Hydrogen Production

Abstract

Hydrogen is an environmentally friendly energy source that is crucial in addressing global climate change and energy shortages. Microalgae are a highly appealing method for generating biohydrogen, which is a clean and environmentally friendly energy source. This strategy can help reach carbon neutrality and ensure the sustainability of bioenergy. The production of biohydrogen by dark fermentation is seen as a promising way of using clean, renewable energy. Microbial fermentation activities produce the majority of hydrogen in the biosphere. The biological synthesis of hydrogen is an attractive approach to renewable energy production, utilizing both photosynthesis and fermentation processes. Certain types of green algae, blue-green algae (cyanobacteria), fermentative and photosynthetic bacteria, and archaea can produce hydrogen by using light energy and/or various organic substances. Our work aims to study the role and influence of biohydrogen production by dark fermentation using microalgae, as well as improve the production yield, with a view to wider application in the future
