Universidad de Zaragoza (orcid)0009-0008-0638-2640 Techno-economic assessment of the sorption enhanced methanation: Levelized cost of methane, performance indicators and sensitivity analysis 2026 This work presents the first techno-economic assessment of sorption-enhanced methanation (SEM) based on TRL-3 experimental data, comparing it with conventional methanation (CM). Experimental tests fitted a kinetic model for reactor sizing in a 200 MWe plant. While SEM requires more catalyst (223.7 kg/MWe) than CM (70–90 kg/MWe), both systems show similar CAPEX (∼700-800 M€). The results highlight that SEM generates three times higher income due to superior product purity. Conventional methanation often faces economic losses when producing 95% CH4, as levelized costs (LCOM, 2.4 – 3.3 €/kg) exceed market prices (0.5 €/kg). Although CM can be profitable at 99% purity market, SEM achieves 99.9% CH4, accessing a premium market (12 €/kg) that guarantees profitability even in unfavorable hydrogen cost scenarios. Consequently, SEM emerges as a key technology to enhance the economic viability and maturity of innovative H2 production.
