Innovative membrane technologies

Task 1.2: Innovative membrane technologies

Overall objective: To develop dense inorganic membranes for pre-combustion decarbonisation processes, e.g., steam-methane reforming, and hybrid membranes for post-combustion CO2 separation.

Contribution to one or more of the overall goals/objectives of BIGCCS

The membrane technologies investigated are core components in several of the pursued CO2 capture schemes. Therefore, membrane performance in terms of flux, selectivity and stability under realistic operation conditions directly address the overall project goals related to capture rate, cost reduction and fuel-to-electricity efficiency.

Task 1.2 achievements thus far

  1. State-of-the-art materials developed for Hydrogen Transport Membranes (HTM) and Oxygen Transport Membranes (OTM)
  2. Fabrication of asymmetric tubular OTM and HTM, 30-50 cm long
  3. Attained fundamental understanding of the mechanisms governing the hydrogen production rate in HTM
  4. Asymmetric tubular OTM successfully tested with stable flux for > 200 hours
