Year: 2025

Abstract: The transition to oxygen-fuel energy cycles for the combined production of electricity and hydrogen production is a promising way to reduce carbon dioxide emissions into the atmosphere in the energy sector. This paper describes the developed oxygen-fuel energy complex with an integrated steam methane reforming unit based on the SCOC-CC cycle for the production of electricity and hydrogen with minimal carbon dioxide emissions into the environment. During the thermodynamic study, it was found that when the produced hydrogen at the outlet of the SMR unit changes from 0 kg/s to 1.33 kg/s, the fuel heat utilization coefficient of the oxygen-fuel energy complex with an integrated SMR unit based on the SCOC-CC cycle is 1.7–6.1 % higher than that of the oxygen-fuel energy complex with an integrated SMR unit based on the Allam cycle. This is due to the fact that when using an oxygen-fuel complex with an integrated PCM unit based on the SCOC-CC cycle, the consumption of methane supplied to the reformer furnace is reduced by 0.26–0.92 kg/s relative to the closest analogue.
