Fig. 4: Different routes to mitigate emissions from remaining liquids and natural gas in net-zero scenarios.
From: Drivers and implications of alternative routes to fuels decarbonization in net-zero energy systems
These routes are abstracted from the results of the illustrative core cases discussed above to highlight the dominant feature of each quadrant. Modeled scenarios—whether from the simple model or more complex models—will typically combine elements from different quadrants, even if one option is dominant. UC Unconstrained case, BC Biomass Constrained case, SC Sequestration Constrained case, SBC Sequestration and Biomass Constrained case. BECCS refers to Bioenergy with Carbon Capture and Sequestration, DAC refers to Direct Air Capture, and DACCS refers to DAC with Carbon Sequestration.
