“…In proton exchange membrane (PEM) electrolysis, the levers to achieve higher efficiency and higher current density are thinner membranes and more active catalysts with reduced noble metal loading [8][9][10]. The latter will enhance the sustainability of PEM electrolysis [11] and the option to scale-up the annual production volumes. In addition, the scale-up of the technology will further reduce costs for almost all component parts in the PEM electrolysis system [12].…”

Green hydrogen production by electrolysis using renewable power allows for decoupling the time and location of hydrogen production and use. Even if pipeline transport of hydrogen is most economic for large scale, transport by trailers will be present in near and mid‐term future since the construction of a hydrogen pipeline network will take a long time. Furthermore, the volume of trailer transport will increase with increasing hydrogen demand raising the question what the best hydrogen carrier is. Within this contribution, different hydrogen carriers are compared regarding their energy efficiency and their practicability. In addition, an overview of hydrogen compression technology is given including piston, membrane, screw, electrochemical, thermal, and turbo compressors. As hydrogen carriers, gaseous compressed hydrogen (CGH), liquid hydrogen, (LH2), liquid organic hydrogen carriers (LOHC), metal organic frameworks (MOF), hydrides and ammonia are evaluated. CGH is most energy efficient for short transport distances, but for longer distances a higher hydrogen density is required. Here, LH2 and LOHCs compete both showing a high hydrogen density. However, if larger hydrogen liquefiers are built in future, LH2 is more practical due to its better energy efficiency (at least for fueling station supply) and proven technology readiness.

“…A typical air separation unit plant produces the oxygen required for gasification, with a 85% purity by volume. Considering electricity (for the air compression) and thermal energy (for the air distillation) an environmental impact value in term of CO2-equivalent emission equal 282 kgCO2eq/tO2 to can be obtained [33], The environmental impact value for pure hydrogen production was considered for the case of water electrolysis using solar energy as a primary energy source [34]. This value is lower than CO2-equivalent emission producing pure hydrogen by natural gas, oil, coal, or other raw material, but also lower than impact by wind energy or geothermal energy.…”

The anaerobic digestion (AD) of organic fraction municipal solid wastes (OFMSW) is a well-known technology for the valorization of wastes with the production of biogas, the latter usually used in power plant. Nevertheless, more and more effort is necessary in order to produce energy and chemicals from renewables as a strategy for replacing fossil fuels and reducing carbon dioxide in the atmosphere. In particular, methanol is considered as a promising energetic vector of the future since it may be produced from renewables and it may be used as a reactant for fuels and chemical production. Currently, methanol is industrially produced via syngas conversion using natural gas as the main feedstock. Biomethane produced in AD unit may be used as an alternative to natural gas for production of syngas that may be used for methanol production. In this work, a techno-environmental assessment for methanol production from biogas is presented and discussed, with focusing on the effect of side-unit, e.g. biomass gasification, carbon dioxide capture and renewable hydrogen production, on the environmental impact. Results show that highest CO2 saving is calculated for the biomass-integrated plant, although more detailed investigations, e.g. cost analysis, need for a proper assessment.

Production of energy or chemicals from biomass and several waste substrates appears a concrete strategy for replacing fossil fuels and reducing carbon dioxide emissions in the atmosphere. In particular, methanol from biomass or bio-waste is considered a reliable energy vector and key intermediate for industrial chemistry. Currently, methanol is industrially produced via syngas conversion using natural gas as the main feedstock. Biomethane produced via anaerobic digestion (AD) of Organic Fraction Municipal Solid Wastes (OFMSW) may be used as an alternative to natural gas for production of syngas with optimal composition via commercialized reforming processes. In this work, a technoenvironmental assessment for methanol production from biogas is presented and discussed. In particular, three case studies were assessed to minimize the environmental impact of biomethanol production.
