“…The feedstocks investigated so far are steamed potato peel, wheat straw and sweet sorghum stalks [110][111][112]. In connection with a European research study, HYVOLUTION, the life cycle environmental impacts of pilot production of H 2 through thermophilic fermentation, and photo fermentation of potato peel was compared to production of H 2 from natural gas through steam methane reforming (SMR) [112]. It was demonstrated that the bio-H 2 production had approximately 5.7 times higher environmental impacts (negative impacts on the environment) than a centralized SMR.…”

“…Recirculation of the sewage reduces the environmental impacts considerably to having only approximately two times more environmental impact than SMR. If instead biomethane were produced for use in the SMR the environmental impact would be reduced to less than 1/3 of the traditional SMR [112]. On the other hand alternative use of the peel would be as animal feed and Djomo et al showed that the production of bio-H 2 is more beneficial than the use as animal feed by a factor of 2-3 [110].…”

Among the various renewable energy sources, biohydrogen is gaining a lot of traction as it has very high efficiency of conversion to usable power with less pollutant generation. The various technologies available for the production of biohydrogen from lignocellulosic biomass such as direct biophotolysis, indirect biophotolysis, photo, and dark fermentations have some drawbacks (e.g., low yield and slower production rate, etc.), which limits their practical application. Among these, metabolic engineering is presently the most promising for the production of biohydrogen as it overcomes most of the limitations in other technologies. Microbial electrolysis is another recent technology that is progressing very rapidly. However, it is the dark fermentation approach, followed by photo fermentation, which seem closer to commercialization. Biohydrogen production from lignocellulosic biomass is particularly suitable for relatively small and decentralized systems and it can be considered as an important sustainable and renewable energy source. The comprehensive life cycle assessment (LCA) of biohydrogen production from lignocellulosic biomass and its comparison with other biofuels can be a tool for policy decisions. In this paper, we discuss the various possible approaches for producing biohydrogen from lignocellulosic biomass which is an globally available abundant resource. The main technological challenges are discussed in detail, followed by potential solutions.

“…Generation of volatile fatty acids as by-products decreases the pH of the fermentation medium, which can be corrected with an alkaline agent. However, the latter causes significant environmental impact (Ochs et al 2010) and also restricts water recirculation due to accumulation of salts. Moreover, addition of caustic agents like sodium hydroxide incurs significant costs (Ljunggren et al 2011a, b).…”

“…Ochs et al (2010) performed a LCA evaluation (cradle-to-gate) of a proposed plant for thermophilic production of biohydrogen using potato steam peels under the assumption of a complete substrate oxidation to produce only CO 2 and sewage as by-products 1. The study revealed that, during thermophilic fermentation, process inputs such as phosphates and alkali produced using fossil fuels are the most potential contributors to high environmental impact 2.…”

Apart from being applied as an energy carrier, hydrogen is in increasing demand as a commodity. Currently, the majority of hydrogen (H2) is produced from fossil fuels, but from an environmental perspective, sustainable H2 production should be considered. One of the possible ways of hydrogen production is through fermentation, in particular, at elevated temperature, i.e. thermophilic biohydrogen production. This short review recapitulates the current status in thermophilic biohydrogen production through fermentation of commercially viable substrates produced from readily available renewable resources, such as agricultural residues. The route to commercially viable biohydrogen production is a multidisciplinary enterprise. Microbiological studies have pointed out certain desirable physiological characteristics in H2-producing microorganisms. More process-oriented research has identified best applicable reactor types and cultivation conditions. Techno-economic and life cycle analyses have identified key process bottlenecks with respect to economic feasibility and its environmental impact. The review has further identified current limitations and gaps in the knowledge, and also deliberates directions for future research and development of thermophilic biohydrogen production.

a b s t r a c tThe objectives and methodology of the EU-funded research project HYVOLUTION devoted to hydrogen production from biomass are reviewed.The main scientific objective of this project is the development of a novel two-stage bioprocess employing thermophilic and phototrophic bacteria, for the cost-effective production of pure hydrogen from multiple biomass feedstocks in small-scale, cost-effective industries. Results are summarised of the work on pretreatment technologies for optimal biodegradation of energy crops and bio-residues, conditions for maximum efficiency in conversion of fermentable biomass to hydrogen and CO 2 , concepts of dedicated installations for optimal gas cleaning and gas quality protocols, as well as innovative system integration aimed at minimizing energy demand and maximizing product output.The main technological objective is the construction of prototype modules of the plant which, when assembled, form the basis of a blueprint for the whole chain for converting biomass to pure hydrogen. A brief outline is presented of the progress made towards developing reactors for thermophilic hydrogen production, reactors for photoheterotrophic hydrogen production and equipment for optimal gas cleaning procedures.
