Global hydrogen production is dominated by the Steam-Methane Reforming (SMR) route, which associated with significant CO2 emissions and excess process heat. Two paths to lower specific in SMR are investigated: (1) integration of capture compression for subsequent sequestration or utilization, (2) electrolysis increased production. In both cases, heat utilized drive reduction options. Four different design regimes carbon identified. Techno-economic analyses performed study effect mitigation...
