The NG combustion-related CAP emissions for SMR were estimated by converting the hydrogen-based emission values to NG-based emissions using the 0.565 mmbtu share of NG combusted per 1 mmbtu H 2; see Table 1. The derived NG combustion EF for SMR process are shown in Table 5, which are added as new data in the EF tab in GREET 2019.
