Biohydrogen is considered as an attractive clean energy source due to its high energy content and environmental-friendly conversion. Analyzing various economic scenarios can help decision makers to optimize development strategies for the biohydrogen sector. This study surveys econometric models of biohydrogen development, including input-out models, life-cycle assessment approach, computable general equilibrium models, linear programming models and impact pathway approach. Fundamentals of each model were briefly reviewed to highlight their advantages and disadvantages. The input-output model and the simplified economic input-output life-cycle assessment model proved most suitable for economic analysis of biohydrogen energy development. A sample analysis using input-output model for forecasting biohydrogen development in the United States is given.

The global shift towards renewable energy sources highlights the urgent need for sustainable hydrogen production, with photo-fermentative hydrogen evolution (PFHP) emerging as a promising solution. This review addresses the challenges and opportunities in optimizing PFHP, specifically the role of photosynthetic bacteria (PBS) in utilizing sunlight for hydrogen production. We focus on the key factors influencing PFHP, including light intensity, reactor design, substrate selection, carbon-to-nitrogen ratio, metal ions, temperature, pH, charge transfer and genetic engineering.

Energy from renewable resources has been growing in popularity, which ultimately helps reduce emissions of greenhouse gases (GHGs) and contaminants. Since hydrogen (H) has a higher combustion production of energy than hydrocarbon fuels, it has been identified as a clean, sustainable, and environmentally friendly energy source. There are several benefits to producing biohydrogen (bioH) from renewable sources, including lower cost and increased sustainability.

Lignocellulosic biomass (LCB) is expected to play a critical role in achieving the goal of biomass-to-bioenergy conversion because of its wide distribution and low price. Biomass fermentation is a promising method for the sustainable generation of biohydrogen (bioH) from the renewable feedstock. Due to the inherent resistant structure of biomass, LCB needs to be pretreated to improve its digestibility and utilization.
