Sector-Coupled Removal Demand Modelling
Capacity-expansion models that jointly optimise gas and electricity systems under varying capture-cost assumptions quantify the residual emissions a decarbonised economy cannot eliminate, enabling planners and investors to size required direct air capture capacity and policy support for a given jurisdiction and target date.
Developed mainly in: United StatesImpacting: North America and Europe
A capacity-expansion study using the BRIDGES sector-coupled gas-electricity model for California assessed liquid-solvent and solid-sorbent direct air capture under varying cost assumptions. Cost-optimal 2045 net-zero pathways include 16–33 MtCO2 per year of DAC, which allows continued natural gas use for industrial heat and power, and offsets residual emissions such as refrigerant leaks.
