Abstract:In this article the concept, the materials and the exploitation potential of a photosynthetic microbial electrochemical cell for the production of hydrogen driven by solar power are investigated. In a photosynthetic microbial electrochemical cell, which is based on photosynthetic microorganisms confined to an anode and heterotrophic bacteria confined to a cathode, water is split by bacteria hosted in the anode bioactive film. The generated electrons are conveyed through external "bio-appendages" developed by the bacteria to transparent nano-pillars made of indium tin oxide (ITO), Fluorine-doped tin oxide (FTO) or other conducting materials, and then transferred to the cathode. On the other hand, the generated protons diffuse to the cathode via a polymer electrolyte membrane, where they are reduced by the electrons by heterotrophic bacteria growing attached to a similar pillared structure as that envisaged for the anode and supplemented with a specific low cost substrate (e.g., organic waste, anaerobic digestion outlet). The generated oxygen is released to the atmosphere or stored, while the produced pure hydrogen leaves the electrode through the porous layers. In addition, the integration of the photosynthetic microbial electrochemical cell system with dark fermentation as acidogenic step of anaerobic digester, which is able to produce additional H2, and the use of microbial fuel cell, feed with the residues of dark fermentation (mainly volatile fatty acids), to produce the necessary extra-bias for the photosynthetic microbial electrochemical cell is here analyzed to reveal the potential benefits to this novel integrated technology.

“…The processes that have passed the first selection are subsequently studied using the AM method, represented by the quantification of each material and energy flow in a flow-chart, which allows estimation of the amount of useful energy [1], adopting a life cycle assessment (LCA) approach: each energy contribution is included. Focusing on indirect energy is particularly important, because it is often not considered in the present literature.…”

In the present chapter, the energy sustainability of anaerobic digestion (AD) technology is discussed. A procedure in three steps is described and then applied to AD. The suggested procedure can help in local planning, in allocation financial resources for the exploitation of new energy processes as well as in selecting the most sustainable choice of several research programs from an energetic point of view. The sustainability scores permit, moreover, the comparison of many operating options for the same technology to identify the best operational conditions towards a sustainable energy perspective. The content of the present chapter is partially contained in [1].
