Fig. 5: Sensitivity of LCOH by SMR with CCS to learning rates.

From: Technological evolution of large-scale blue hydrogen production toward the U.S. Hydrogen Energy Earthshot

Fig. 5

a LCOH under two boundary scenarios of learning rates. b LCOH under the range of 100%–150% time-based learning rates, except for O&M cost learning rates, which are equal to 5%–10% for SMR, PSA, and CO2 compression. Note to Fig. 5: P1 means a percentage relative to the base learning rate, whereas P2 means the learning rate on an absolute basis. Note to abbreviations: CCS means carbon capture and storage; LCOH means levelized cost of hydrogen; LR means learning rate; O&M means operating and maintenance; PSA means pressure swing adsorption; and SMR means steam methane reforming.
