A direct air capture (DAC) technology developed at Trinity College Dublin is undergoing industrial-scale testing at Dublin Airport, with early results highlighting its potential to supply high-purity carbon dioxide for sustainable aviation fuel (SAF) and e-fuel production.
The system has been running for three months in a live operational environment, supported by European Innovation Council funding. The team behind the technology aims to scale it for commercial deployment.
The system captures carbon dioxide directly from ambient air and releases it using low-grade industrial waste heat, resulting in a purified CO2 stream. While the precise materials are not disclosed, the team said that it focused on optimising energy use and operational conditions to improve capture efficiency and enable industrial deployment.
“By advancing and integrating this technology across industries, we are not only reducing emissions but also creating economic opportunities through supplying high-purity CO2 that align with global sustainability goals,” said Professor Wolfgang Schmitt, who helped develop the system.
