Project Details


The global average surface temperature has increased by 1.07 °C to date with the increasing CO2 concentration in the atmosphere being the primary driving force of this temperature increase. All additional heating of the surface of the earth increases the potential of severe and irreversible changes to the climate. Thus, it is widely suggested that carbon capture technologies are necessary to avoid further temperature increase. In addition, there is an urgent need for renewable carbon sources to produce fuel for the heavy transport sector but also to provide the chemical industry with renewable carbon for production of plastics and chemicals. Power-based direct air capture of CO2 with utilization technologies can provide alternative routes to produce these fuels, plastics, and chemicals.
In this context, the use of liquid sorbent carbon capture with high-temperature regeneration of the CO2 followed by a fuel synthesis process can become one of the main paths towards a carbon neutral world. The process uses a high-temperature calcination process to regenerate the CO2 from the sorbent at around 800 °C.
In this project, the high-temperature regeneration of the CO2 is optimized to improve the integration potential with the following fuel synthesis processes. The calcination mechanism will be experimentally examined in different reaction atmospheres in both micro scale and in a lab scale calciner. Likewise, the following fuel synthesis is investigated experimentally to explore the impact of the calcination gas product.
The results obtained by the experimental work constitutes the foundation of the practical considerations in a commercialization context. Moreover, the experimental results are used to produce thermodynamic models of the entire system to evaluate the technical feasibility of such a system. A simultaneous study of the techno-economic feasibility and environmental impacts from the DACCU system facilitates a unique optimization opportunity that considers all these different aspects.

In summation, the goal of this report is to assess how DAC technologies integrated with fuel syntheses influence the CO2 concentration in the atmosphere and at the same time be a techno-economically feasible solution.
