BIOHYDROGEN PRODUCTION: RECENT ACHIEVEMENTS AND STATE OF THE ART
The growing population of the planet, the increase in demand for energy, the depletion of fossil fuels and the detrimental effect of their combustion products on the ecological state of the biosphere, as well as on global climate change, are not only urgent problems of our time, but also a powerful incentive to search for alternative energy sources. Molecular hydrogen is an energy carrier with a high specific heat of combustion and a zero carbon emission, since water is formed as a result of the oxidation of hydrogen. H2 produced by microorganisms is called “biohydrogen”. This review considers the modern achievements of science in the field of studying hydrogen bioenergy.
