“…This approach enjoys the benefit of eliminating further O 2 compression. Nevertheless, the absorbed power via the SOFC/SOEC combination is higher than zero, and therefore, commensurate to the operational temperature (Equation [4]). The oxygen generated by the electrolyzer was at the same pressure as that of the oxygen present in the air.…”

Summary An innovative polygeneration structure is proposed based on the oxyfuel power generation (OPG) system integration with carbon dioxide (CO2) capture, CO2 power system, NH3/H2O absorption refrigeration (AR) unit, and organic Rankine power (ORP) cycle. In this regard, a combination of solid oxide electrolysis cell (SOEC) and solid oxide fuel cell (SOFC) is applied to produce the required pure oxygen for the OPG system. The proposed system simultaneously produces 7204 kmol/h hot water, 149.3 kmol/h liquid CO2, and 102.4 MW power in different cycles. Energy and exergy analyses are performed to evaluate the proposed system. The thermodynamic modeling and simulation of power and refrigeration cycles are performed in Aspen HYSYS software, and verified with high accuracy. Also, an integrated SOEC/SOFC simulation has been done using developed computer code in MATLAB programming. The overall electrical efficiency and the AR coefficient of performance are calculated at 31.55% and 0.4803, respectively. In addition, the thermal and exergy efficiencies of the proposed system are 65.10% and 70.60%, respectively. The exergy analysis indicates the combustion chamber's highest exergy destruction with a share of 35.26%. In the next rank, the heat exchangers (26.42%) and turbines (16.98%) have the largest share of degraded exergy among other devices. The sensitivity analysis demonstrates that when the oxygen productivity increases from 9050 to 9275 kg/h, the electrical efficiency in the total integrated structure and the liquid CO2 productivity rise to 34.57% and 6480 kg/h, respectively. Also, by increasing the natural gas entering the proposed structure from 2375 to 2550 kg/h, the exergy efficiency of the structure increases to 71.19% and its thermal efficiency decreases to 58.70%. Highlights A novel polygeneration system to produce power, liquid CO2, and heat is introduced. Integration of oxyfuel/ORC/CO2 power plants and absorption cooling unit is applied. A solid oxide fuel cell/electrolyzer technology is used to produce pure oxygen. The electrical and exergy efficiencies of the overall system are 31.55% and 70.60%. The exergy analysis indicates the combustion chamber has the highest exergy destruction.

“…The main renewable technologies employed or modelled for green hydrogen production are solar technologies, mainly photovoltaic (PV) systems [22]. Solar and wind-hydrogen coupling have been widely studied using case studies analysis, techno-economic assessment, and simulations [23][24][25][26][27], showing good economic potential depending on both local wind or PV electricity cost and the electrolysers technology maturity [16,28].…”

The use of green hydrogen to power vehicles is recognized as contributing to the mitigation of the greenhouse gas (GHG) emissions responsible for climate change. On the other hand, the need for reducing GHG emissions is even more urgent in densely industrialized areas, traditionally located nearby highly populated zones. In these areas, road transportation is a relevant source of environmental pressures affecting air quality and the nearby communities' health: in Europe, private vehicles, vans, trucks, and buses produce more than 70% of the overall greenhouse gas emissions from transport, as well as particulate matter and nitrogen oxide. The European Hydrogen Strategy considers using green hydrogen as an energy carrier to de-carbonize industry and the transport sector, highlighting the need for the infrastructure to produce, store, and distribute hydrogen. The spatial configuration of the industrial sites and the existing infrastructure can facilitate the creation of hydrogen hubs serving both the logistics needs of companies and the public and private mobility in an urban-industrial symbiosis approach. Thus, this study aims at investigating the opportunities offered by the creation of synergies between industrial clusters and the nearby urban areas to improve the local sustainability by supporting the deploying of low-carbon mobility using green hydrogen. The available literature is reviewed in order to schematise and discuss the sustainability-related basis of adopting such a strategy, presenting an updated analysis of the latest research and application results suitable for future research applications and for supporting decision-making processes.

“…Recent research results demonstrate hydrogen production via polymer electrolyte membrane electrolyzer has lower environmental effects than other traditional methods (e.g., coal gasification and reforming, steam methane reforming). On the economical hand, geothermal energy-based systems show the lowest cost of electricity for hydrogen production, unlike the natural gas [3].…”

Blending hydrogen into the natural gas infrastructure is becoming a very promising practice to increase the exploitation of renewable energy sources which can be used to produce “green” hydrogen. Several research projects and field experiments are currently aimed at evaluating the risks associated with utilization of the gas blend in end-use devices such as the gas meters. In this paper, the authors present the results of experiments aimed at assessing the effect of hydrogen injection in terms of the durability of domestic gas meters. To this end, 105 gas meters of different measurement capabilities and manufacturers, both brand-new and withdrawn from service, were investigated in terms of accuracy drift after durability cycles of 5000 and 10,000 h with H2NG mixtures and H2 concentrations of 10% and 15%. The obtained results show that there is no metrologically significant or statistically significant influence of hydrogen content on changes in gas meter indication errors after subjecting the meters to durability testing with a maximum of 15% H2 content over 10,000 h. A metrologically significant influence of the long-term operation of the gas meters was confirmed, but it should not be made dependent on the hydrogen content in the gas. No safety problems related to the loss of external tightness were observed for either the new or 10-year-old gas meters.
