암모니아 터미널의 수소 연료 가스터빈-SOFC 통합 공정 설계

초록

In this study, we design and quantitatively evaluate an integrated ammonia- to-hydrogen power terminal. The process consists of an ammonia cracker, hydrogen purification, and a power block in which a hydrogen gas turbine and a solid-oxide fuel cell (SOFC) operate in parallel; the cracker furnace is fired with an NH₃–H₂ blended fuel for tighter thermal integration. Under blue and green ammonia scenarios, we compare the levelized cost of electricity (LCOE) and carbon intensity (CI) while optimizing the hydrogen split between the two units. The most balanced cost–efficiency outcome is achieved at a GT:SOFC fuel-allocation ratio of 1:1. SOFC model and sensitivity analyses confirm the influence of key design variables. The proposed scheme delivers simultaneous economic and environmental benefits through heat- and mass-integration.
