Figure 9. Electricity-related mitigation analysis for the double-flash case: (A) specific electricity-demand trajectories under the three efficiency scenarios; (B) grid-only and additional process-efficiency contributions to modeled emission reductions in 2030 and 2060 relative to the consistently rebased 2025 electricity-factor baseline of 0.5777 kg CO2e/kWh; and (C) economically allocated oxygen-production emissions at 0.65 and 0.46 kWh/Nm3 under a common electricity factor. EF: Emission factor.
