Fig. 3: Detailed cost breakdown of solar-driven DAC and CO2 utilisation (DACCU) in the base case.
From: Solar-driven direct air capture to produce sustainable aviation fuel
a Minimum selling price (MSP) of sustainable aviation fuel (SAF). b Levelized cost of the proposed solar-driven DACCU process. c Annual operational cost, disaggregated by process step. d Total capital expenditure (CAPEX), divided into two main sections: solar-driven DAC and CO2-to-SAF. The DAC and solar calcination are subsections of the solar-driven DAC. e Global average market price of SAF and jet fuel. TDFC total direct field costs, IFC indirect field costs, TNFC total non-field costs.
