Spanish Scientists Developed New Membrane That Cuts Hydrogen Processing Time from 3 Days to 3 Hours
The Daily Galaxy • • science
Key Points:
- A research team from ICMM-CSIC has developed a new membrane for hydrogen purification that increases permeability by 800% and selectivity by 30%, addressing key challenges in large-scale hydrogen use.
- The membrane uses polysulfone combined with a specially designed porous component, creating tiny channels that allow hydrogen molecules to pass while blocking larger gases like methane and carbon dioxide.
- This innovation overcomes the typical trade-off between permeability and selectivity in gas separation membranes, achieving significant improvements in both simultaneously.
- The membrane is produced via a mechanochemical synthesis method, reducing production time from three days to three hours, lowering energy use and solvent consumption, and making it more environmentally friendly and cost-effective.
- The breakthrough has strong potential for industrial applications, particularly in petrochemicals and green hydrogen systems, where efficient and rapid hydrogen purification is essential.
