EngD candidate on EcoCapture project

In this project the objective is to develop a cost-effective method and process to avoid/minimize oxidative degradation, by removing oyxgen (downto ppm level) in between the sorption step (in air) and desorption step (at elevated temperature).

Activities will include: Evaluation and selection of oxygen removal options, oxygen removal pilot unit design and modelling. After construction and installation (by projectpartners), testing and evaluation of the developed technology under real life conditions using the UT pilot plant is foreseen.

Direct Air Capture is identified as key enabling technology to meet Europe’s climate strategy and achieve Net Zero emissions in 2050. For the direct removal of CO2 from air, a highly selective sorbent or solvent is needed. For this, typically primary amines are selected as functional groups. A major issue when using amines is the loss of activity due to oxidative degradation, related to the presence of oxygen at regeneration conditions (at elevated temperature). The EcoCapture project addresses this issue.

EcoCapture is a multipartner project to improve DAC performance for these amine-based solid sorbent processes in general and in particular for DAC processes with sorbent circulation, as being developed by ReCarbn, spin-off company from the University of Twente. Carbotreat is a construction company, experienced in CO2 capture installations. EcoCapture is financed by the EU regional program EFRO-OOST.
