Renewable energy-powered direct air capture with subsequent utilisation offers a sustainable decarbonisation strategy for a circular economy. Whereas current liquid-based capture technology relies on natural gas combustion for high-temperature calcination, restricting the transition to fully renewable operation. In this study, the authors show a 1 Mt CO₂/year solar-driven process that adopts a hydrogen fluidised solar calciner with onsite catalytic conversion of CO₂ into sustainable aviation fuel.
