Biohydrogen production, storage, and delivery: A comprehensive overview of current strategies and limitations

New insights into Chlorella vulgaris applications

“…Even though hydrogen mobility is now more affordable costing 7 Euro per 100 km than traditional fossil fuels 15.6 Euro per 100 km for the first time in the European Union, hydrogen is still in its early stage in the majority of nations which impedes the advancement of hydrogen infrastructure worldwide (Maroušek et al, 2022). The low yield and high cost of biohydrogen production limit its industrial scale production and make it uncompetitive with other biofuels like biodiesel besides, the challenges including biohydrogen purification, storage, delivery, and safety, must be addressed to ensure hydrogen's viability and competitiveness (Feng et al, 2023). It has been demonstrated that nanoparticles enhance biohydrogen synthesis in microbial systems by acting as catalysts, promoting enzymatic processes that produce hydrogen (Maroušek, 2022), and enhancing the biomass productivity of the microalgae (Hidalgo et al, 2023).…”

An Updated Review of Recent Applications and Perspectives of Hydrogen Production from Biomass by Fermentation: A Comprehensive Analysis

“…The versatility of biohydrogen allows it to be used in a variety of market sectors. Automobile manufacturers are aware of the energy insufficiency of petroleum derivatives and are therefore betting on the development of new fuels [165,166,[170][171][172]. Thus, using biohydrogen is a promising option that has already been tested in some countries.…”

“…Furthermore, the ability to convert any biodegradable waste into H 2 is its main advantage [173]. The adoption of sustainably produced and renewable fuels to replace fossil fuels in the transportation sector will significantly improve combustion efficiency, reduce toxic gas emissions that contribute to the intensification of the greenhouse effect, and also contribute to lower prices, efficiency, and ecologically correct goals in the transportation system, which invests heavily in this improvement [165][166][167]171,174].…”

“…Hydrogen is a fuel with zero carbon production and can be used to power internal combustion engines and vehicles [157,171]. On the other hand, a factor that is recurrently discussed with alternatives to fossil fuels is the autonomy of cars powered by hydrogen or electricity.…”

Biohydrogen Production under Aerial Conditions by a Nitrogen-Fixing Bacterium Isolated from a Steel Signboard

“…H 2 has a very high combustion efficiency-2.75 times that of fossil fuels-and because only water remains after combustion, it does not burden the environment. However, H 2 is almost nonexistent in Earth's atmosphere [2,3]. Currently, the primary method of producing H 2 is steam reformation, which uses methane gas as its main reagent; this method relies on fossil fuels and thus does not solve the fundamental problem of fossil fuel use [4,5].…”
