We will assess the role of adsorption-based DAC processes in the context of the UK energy system. Specifically, we aim to:
The deployment of DAC processes faces two key challenges:
1) DAC units use ambient air as the feed stream, and so must be designed such that they are robust to seasonal fluctuations in atmospheric conditions (temperature, humidity). For the first time, we will couple the optimisation of DAC units with design tools which consider the operability of the units subject to variability in the atmospheric conditions. We will utilise a dataset of ambient conditions at multiple UK industrial clusters to assess the feasibility of the unit operation under conditions present in our pre-existing industrial centres.
2) Current DAC unit designs are energy intensive. To yield negative emissions, careful attention must be paid to the full scope of emissions associated with the CO2 capture, transport, and storage chain for DAC. For the first time, we will consider the integration of DAC units within industrial clusters to allow for access to shared infrastructure and resources. We will compare performance to stand-alone DAC systems to identify in detail the specific strategic benefits for cluster-integration of DAC units.
We will assess the deployment of DAC in the context of three UK industrial clusters, the Humber cluster, the Northwest Cluster, and the Scottish Cluster. We will incorporate cluster-specific variability of atmospheric conditions and availability of shared recourses into our analysis to generate a roadmap for deployment of DAC processes at these locations.
The project aims to generate the following outputs:
