Background
Direct air capture (DAC) of CO2 is key to reaching the net‐negative CO2 emission goal. DAC will together with other capture technologies form the backbone of future negative emission technologies, and coupled with PtX, the DAC-PtX combination can form the base load for future production of e-fuels and other carbon-based commodities.
The successful deployment of DAC technologies highly depends on the availability of multiple other factors, such as carbon sequestration or utilization options, and to fully realize the climate benefits of DAC, DAC should be integrated into a low carbon energy system. Despite many technical and economic challenges to be solved for DAC-PtX systems their successful integration into existing energy systems is deemed paramount to technology deployment. DAC coupled to PtX systems further enables lower capture costs with only marginal cost increase on eFuels or eChemicals production. The optimal integration of DAC with other technologies and into energy systems, assessed through advanced modelling, is an unmet need to fully exploit DAC.
Objectives
The project will provide guidelines for stakeholders across the entire value chain, covering both technology and SSH aspects by assessing technology, economy, business models, and regulatory issues for DAC deployment, consolidated into recommendations for how DAC can efficiently be system integrated. The project will therefore ensure proper deployment of direct air capture technology and ensure that DAC-PtX solutions are developed in a way that ensures successful integration in an optimum way.
- Model the thermodynamics of DAC processes.
- Analyse the energy system impacts.
- Investigate the social acceptance and economic consequences of direct air capture.
