Development of Low-Cost Zeolites for Cost-Efficient Carbon Capture

Carbon capture and storage (CCS) is necessary for Sweden to reach zero net greenhouse gas emissions by 2045. The overall cost of CCS in Sweden is estimated to be at least 1000 SEK/tonne of  carbon dioxide(CO₂). The separation of CO₂ from other gases accounts for 70%–80% of the total CCS cost and the CO₂ separation material is one of the main cost drivers. Thus, the development of cost-efficient CO₂ separation materials is crucial for the economic viability of CCS. RISE, Chalmers, and several industrial partners have the ambition to reduce the cost of CCS through the development of low-cost zeolites from industrial residues and natural zeolites for cost-efficient CO₂ separation (both biogenic and abiogenic sources). This project aims to define optimum experimental conditions and estimate the cost of producing zeolites from industrial residues and natural zeolites. The project also aims to evaluate the performance of the produced zeolites in terms of CO₂ separation.
