N2 - Injecting hydrogen (H2) into existing natural gas pipeline grid is a promising solution for long-distance transportation of renewable hydrogen. A critical challenge lies in developing energy-efficient and cost-effective separation technology to extract H2 from the hydrogen-blended natural gas (HBNG). In this study, a hollow fiber DD3R zeolite membrane module (∼800 cm2) was fabricated via ensemble synthesis. The membrane module exhibited a high H2/CH4 selectivity of 197 as well as a H2 permeance of 1.42 × 10−8 mol m−2 s−1 Pa−1 at the feed pressure of 1 MPa during the separation of a 10%H2/90%CH4 mixture. Notably, the H2/CH4 selectivity remained high (95) even at the feed pressure of 5 MPa. The techno-economic feasibility of DD3R zeolite membrane for H2 extraction from HBNG was evaluated based on a two-stage membrane process. The effects of operating pressure, H2 feed concentration, H2 recovery and H2 permeance on H2 separation cost were extensively investigated. When achieving both high H2 purity (99.7 %) and high H2 recovery (70 %), the minimum H2 separation costs for 10 %, 20 %, and 30 % H2 feed concentrations were 1.44, 0.79, and 0.57 $ kg−1, respectively. The dominant membrane capital cost can be further reduced significantly by improving H2 permeance of the membrane.
