Plans for the world's first plant dedicated to the production of bio-based, PFAS-free membranes.

The bio-based membrane company, Cellfion, sets sights on future milestones in the clean energy industry: Anticipated build of the World's First Bio-based, PFAS-Free Membrane Production Plant and the Launch of first-generation membranes.
Stockholm, Sweden - In a pioneering move towards sustainable manufacturing, Cellfion announces plans for the world's first plant dedicated to the production of bio-based, PFAS-free membranes. The primary objective is twofold: to establish an industrial scale pilot line and to facilitate the sale of products in commercial volumes.  

This production line will serve as a significant milestone, paving the way for the construction of Cellfion's factory in the forthcoming years.
Cellfion’s cellulose-based fluorine free membranes open a new chapter in the field of proton-conducting membranes. Based on promising electrical properties the next development steps including fuel celltests have been defined to quickly reach reliable and reproducible membranes and MEAs (membrane electrode assembly) Dr. Albert Hammerschmidt, Former Director for PEM fuel Cell at Siemens.
Ion-selective membranes are pivotal components driving the transition towards green energy through applications such as PEM fuel cells, electrolysers, and large-scale battery technologies such as flow batteries. They play a pivotal role, influencing operational efficiency and the longevity of these energy solutions, thus holding the key to the future of hydrogen and battery industries. The potential applications for these ion-selective membranes extend beyond the energy sector, encompassing fields such as water and air filtration, unlocking a wide array of possibilities.

The prevailing challenge confronting current membrane technology primarily stems from their reliance on "forever chemicals," with the collective name PFAS. With the European Union poised to phase out these substances in the coming years, the industry faces potential disruption unlessnovel, sustainable alternatives emerge to replace the current status quo.Cellfion's groundbreaking solution centers on utilizing cellulose extracted from trees. This approach not only offers an environmentally responsible substitute but also presents a more scalable, economically viable and adaptable solution to meet the industry's evolving needs. The ever-nearing ban of PFAS materials combined with the scarcity of membranes commercially available has driven the company’s development and will see the company release their first-generation products already in 2024, following a successful equity injection and establishment of the pilot plant.

Meet Cellfion- The cleantech startup paving the way towards asustainable energy transition through the commercialization of bio-based membranes

The cleantech startup Cellfion celebrates its first anniversary by securing financing toenable the next steps towards the commercialization of the world’s first biobasedmembrane.
Stockholm, Sweden - The transition to replace fossil fuels with renewable, green energy has been moving at anunprecedented rate in the last decade. However, the expansion of the renewable energy industry doesn’t come without its challenges - especially where energy storage is concerned. Intermittentrenewable energy, such as wind and solar, require a means of storing energy, since the sun isn’talways shining and the wind isn’t always blowing. Rapidly emerging technologies in the formof Redox Flow Batteries and hydrogen can provide the perfect solution, where energy can bestored and discharged upon demand. Cellfion is here to enable these solutions and ensure sustainability with their unique biobased membranes. The unique characteristics and raw materials of Cellfion’s membrane is what sets them apart intoday's market. Cellfion’s technology is made from the most abundant biopolymer on theplanet, cellulose, derived from wood. By extracting cellulose nano fibrils from wood, and modifying the surfaces, the fibrils can be fabricated into sheets of membranes that can be used as critical components in energy storage and conversion devices, such as Redox Flow Batteries and fuel cells. The fact that Cellfion’s membranes are made from an abundant forest materialmakes them not only sustainable, but also cost-effective.
“To the best of our knowledge and extensive research- we are the first company working towards the commercialization of bio-based membranes with no toxic substances at all”, saysLiam Hardey, CEO of Cellfion and Forbes 30 under 30 2022 nominee.
State-of-the-art commercial membranes are often made from PFAS-based substances, asubstance the EU Commission will put restrictions on during 2023. With these restrictions, theneed for alternative membranes is expected to grow massively, and impact start-up Cellfionaims to be at the forefront of this movement.

Cellfion stems from 10 years of research at KTH Royal Institute of Sweden, LinköpingUniversity and RISE. When taking the steps from research to a commercial product, it'simportant to surround the company with good partners that are long-term and believe in thecompany’s mission. Cellfion has now secured a seed investment of 14 million SEK fromAlmi Invest Green Tech, Voima Ventures, Klimatet Invest, LiU Invest and KTH Holding.
”With our investment in Cellfion, we drive the development of an innovative material forenergy storage solutions that enables the transition to renewable energy and thereby reducesgreenhouse gas emissions”, says Karin Edström, Investment Manager at Almi InvestGreenTech. “With their bio-based membrane, which is both cost-effective and more tunablethan today's commercial membrane, Cellfion has a strong position to enter the market”. “This is what deep tech investing is all about, solving big problems that really matters. Thereare huge amounts of energy that are being lost from renewable energy sources due to thelimitations of energy storage. Membranes is of the most crucial components to reach highefficiency. With an ambition to replace toxic and fossilbased membranes, the potential forCellfion is huge. Additionally, the accelerating energy crisis makes the demand for sustainablesolutions greater than ever, and Cellfion has the potential of becoming the new market leader”,states Jenny Engerfelt, Investment Director at Voima Ventures.
The equity injection enables Cellfion to continue the development towards being a scalable manufacturer of sustainable membranes. In the coming years, the company plans to expand their team, begin their rapid prototyping by working with customers and partners, and focus on getting their first product to market. Cellfion’s ambition is to green energy devices.
“If the clean energy industry is to become sustainable, we need to ensure that the materials we are using are also truly sustainable,” says Magnus Wikström, Director of Board at Cellfion.
