Objective and hypothesis
This project’s aim is to provide guidelines for stakeholders across the entire value chain, covering both technology and SSH aspects. This includes the development of an extension to state-of-the-art energy system analysis (EnergyPlan), enabling the assessment of DAC-PtX system performance in existing energy systems. Collectively, the project will assess technology, economy, business models, and regulatory issues for DAC deployment, consolidated into recommendations for how DAC can efficiently be system integrated.

Approach
The three-year project consists of three work packages, all with the same time plan, starting in the beginning of the project and finishing at the end of the project. The reason is the iterative approach between work package 1 and work package 2, where thermodynamic modelling continuously provides input to the energy system modelling. Furthermore, work package 3 will continuously work with work package 2, to assess the SSH aspects. The three work packages will, among other things, investigate DAC processes and the implementation of direct air capture modules in energy system analysis models.

Expected impact/output
DAC is regarded as an inflection point, and the deployment of DAC is a necessity to reach capture rates in the order of Gt CO2 /year, needed to deflect global CO2 emissions. DAC can provide storage capacity and thereby increase the utilised capacity of existing and future intermittent power production. The impact on emission reduction in Denmark is long-term as DAC is not mature, but it is highly important to ramp up activities now to harvest its enormous potential in due time.
