Strategies and economic feasibilities in cyanobacterial hydrogen production

metabolic, genetic and technical methods for obtaining H2 from cyanobacteria. Cyanobacteria are considered potential producers of hydrogen energy that will be economically viable shortly, as they only need cheap salts, water and solar energy to grow. However, producing hydrogen from cyanobacteria still requires extensive work, and the main problem is the small amount of hydrogen energy obtained. To produce large amounts of cyanobacterial hydrogen, the most active wild-type strains must be selected and technological, modular and genetic research must be carried out simultaneously. The low energy efficiency of hydrogen from cyanobacteria also shows the need for comprehensive (c) 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.

Automated summary

Cyanobacteria are potential producers of economically viable hydrogen energy, but the current amount of hydrogen obtained is limited. To produce large amounts of cyanobacterial hydrogen, the most active wild-type strains need to be selected and technological, modular, and genetic research must be conducted simultaneously. The low energy efficiency of cyanobacterial hydrogen also requires comprehensive research.
