Carbon Capture and Utilisation

Carbon capture and utilisation technologies can help address emissions from power generation, and industrial heating and processes. This focus area covers technologies to capture carbon dioxide from flue gas streams of the Energy & Chemicals sector, and natural gas-fired Combined Cycle Gas Turbines (CCGT). Both produce flue gas that is dilute and humid, which makes capture more energy-intensive and costly than it is for the concentrated streams that many existing technologies were designed around. Captured CO₂ must then be used or sequestered. Converting it into platform chemicals or other products with sizeable global market demand offers a route that generates value rather than cost.

We are also open to other solutions that can cost-effectively decarbonise the Energy & Chemicals and semiconductor sectors at scale. These include electric alternatives for high-temperature heat applications, energy efficiency technologies that offer step-change rather than incremental improvements, and novel ways of long-term, stable sequestration of CO₂.  

AEDO’s research focus is therefore on improving capture efficiency and reducing capture costs, and on advancing technically feasible and cost-competitive CO₂-derived chemicals. Our R&D strategy addresses the following challenges:

CO₂ Capture for Dilute and Humid Flue Gas Streams

Challenge statement: Capture low concentration CO₂ flue gas streams (3–8%) under high-humidity (>80%), with 95 mol% CO₂ purity, with a cost of <$75/tCO₂.

Preferred solutions: Modular, stackable systems ideal for brownfield retrofits.

CO₂ Conversion to Platform Chemicals

Challenge statement: Convert 95 mol% CO₂ feed streams into platform chemicals through thermocatalytic, electrochemical, or microbial routes, including any required CO₂ purification and pre-treatment steps, to be competitive with best-in-class green production (e.g. $950/t for methanol and $1,500/t for ethylene).

Preferred solutions: Catalyst and reactor designs that maximise conversion efficiency, product yield.
