20.500.12556/DKUM-96771 Fully integrated hybrid solid oxide fuel cell–rankine cycle system with carbon capture, utilisation, and storage for sustainable combined heat and power production The imperative to combat climate change necessitates the rapid implementation of technologically advanced, zero-emission renewable energy solutions, particularly considering the mounting energy demands and the pressing need to mitigate global warming. The proposed SOFC system, integrated with a modified Rankine Cycle and CCUS technology, offers a highly efficient, renewable system with a net-zero carbon footprint, utilising green biogas as an alternative. The fully integrated system at continuous operation does not require outside heat sources and, besides, its main electricity production can supply 231 households with hot sanitary water. A base case and sensitivity analysis of the system was conducted studying different operating parameters. The base case simulation, conducted at SOFC/reformer operating temperatures of 850 °C/650 °C and operating parameters S/C = 2.5, Uf = 0.70 Ua = 0.1806, yielded an overall efficiency of 71.64%, with a 67.70% electrical efficiency. Further simulations demonstrated that a 1.60% and 1.53% increase in the overall and electrical efficiencies of the proposed alternative, respectively, would be achieved at SOFC/reformer operating temperatures of 950 °C/650 °C. The simulated hybrid system represents a competitive installation in the renewable energy market, which offers a viable and sustainable alternative to traditional forms of energy generation. solid oxide fuel cell steam reforming heat utilisation hot sanitary water carbon capture utilisation and storage power generation uporaba toplote vroča sanitarna voda zajemanje ogljika true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/sustainability © 2024 by the authors Članek v reviji 2026-01-28 09:55:14 2026-01-28 09:55:14 2026-01-29 03:11:47 0000-00-00 00:00:00 2024 0 0 29 str. iss. 11, [article no.] 4389 Vol. 16 May 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-04-25 2024-05-20 2024-05-22 620.92/.98 196996099 10.3390/su16114389 2071-1050 sustainability-16-04389-v2.pdf sustainability-16-04389-v2.pdf 1 DD11EF1E0283F2562EF7EE8BF3EE44C9 b7d185fc5717a485a75e630ad1cfd9f3445925453b48b862dd0767d4803f0349 48624c7f-fc27-11f0-9a72-00155d00018d https://dk.um.si/Dokument.php?lang=slv&id=202672 https://www.mdpi.com/2071-1050/16/11/4389 0 4e9897ba-fc27-11f0-9a72-00155d00018d https://dk.um.si/Dokument.php?lang=slv&id=202673 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
