Cellfion produces bio-based membranes made from nanocellulose fibrils extracted from wood.
The membranes are ion-selective and designed for use in large-scale energy storage applications such as hydrogen fuel cells and redox flow batteries.
The development of these membranes is based on research conducted by Sweden’s Digital Cellulose Center (DCC) on ion-selective membranes.
Cellfion’s primary focus is the manufacturing of nanocellulose membranes for two applications: organic redox flow batteries and PEM electrolyzer.
These applications are used in the production of green hydrogen gas and large-scale energy storage, respectively, with the aim of supporting the electricity grid.
These materials are also potential alternatives to high-cost fossil-based membranes, which may contain controversial “forever chemicals” such as Perfluoroalkyl substances (PFAS).
