a Global map of current high-temperature concentrated solar power (CSP) plants. Each bubble represents an individual plant, with the bubble size proportional to its installed capacity (MW), based on data from the SolarPACES64. b, c Minimum selling price (MSP) of sustainable aviation fuel (SAF) and d, e levelized cost of DACCU, with low-carbon hydrogen sourced at country-specific prices. b and d use local weighted average cost of capital (WACC); c and e use global averaged WACC of 4.2%. AE alkaline electrolyser, PEM proton exchange membrane, SOEC solid oxide electrolysis cell, SMR with CCS steam methane reforming with carbon capture and storage.
