Cellfion raises SEK 76M Series A for PFAS-free membranes

Cellfion Closes SEK 76 Million Series A

Cellfion, a Swedish advanced materials company, has raised SEK 76 million in Series A funding. The round was backed by Almi Invest GreenTech, Voima Ventures, and Klimatet Invest. No lead investor was disclosed.

What Cellfion Does

Cellfion develops and manufactures PFAS-free membranes and filter media made from functionalised nanocellulose. These materials target hydrogen, redox flow battery, energy storage, and ion-separation applications.

The company is a spin-out from more than a decade of research at KTH Royal Institute of Technology and Linköping University. It is headquartered in Stockholm, where it is establishing its first roll-to-roll membrane production facility.

Technology and Market

Cellfion's PFAS-free membranes address a growing need for sustainable materials in energy storage and hydrogen technologies. By using functionalised nanocellulose, the company avoids per- and polyfluoroalkyl substances (PFAS), which are increasingly regulated due to environmental and health concerns. The roll-to-roll production facility in Stockholm is a key step toward scaling manufacturing.

Use of Funds

The SEK 76 million Series A will support the establishment of Cellfion's first roll-to-roll membrane production facility in Stockholm, as well as further development and commercialisation of its PFAS-free membranes and filter media.

Acquisition Angle

For acquirers, Cellfion offers proprietary PFAS-free membrane technology derived from over a decade of academic research, a clear path to scalable production via roll-to-roll manufacturing, and exposure to high-growth markets including hydrogen, redox flow batteries, and energy storage. The company's focus on replacing PFAS-containing materials positions it well amid tightening environmental regulations.
