Ion Membranes
Develops and manufactures tailored, affordable, high-performance, PFAS-free membranes using their patent-pending technology for the cleantech industry
About Ion Membranes
Ion Membranes is an innovative startup specialized in the development and manufacturing of ion exchange membranes and separators, primarily for the green energy sector. These membranes are micron-scale, thin polymer layers that effectively filter at atomic-scale, enabling a wide range of applications in the energy sector, including electrolyzers, fuel cells, and energy storage across various battery technologies. Given their essential role in these technologies, membranes are as vital to the energy industry as microchips are to the electronics industry.
Read full description
There is a significant need for tailored solutions compliant with new environmental regulations (PFAS). However, the membrane market is dominated by major chemical companies that typically offer standard PFAS-noncompliant products. This leaves CleanTech developers struggling to meet their unique technological needs. Additionally, many commercial membranes are expensive and have lengthy lead times, which do not align with the budgets and fast-paced timelines of technological innovation.
Ion Membranes addresses this challenge with an novel approach. Their unique combination of processes and chemistry enables them to deliver tailor-made, PFAS-compliant products with superior performance. Moreover, they can produce short series at lower costs and with a reduced carbon footprint, providing additional advantages beyond PFAS compliance. With their nano-fiber structured solutions, CleanTech developers can optimize their processes, maximize output, and reduce costs, ultimately facilitating a faster and fairer energy transition.
Company's primary target market is energy storage, including battery and hydrogen technologies, which is growing at 38.5% annually and is expected to generate over $25 billion in membrane sales by 2030. Currently, their core products support PEM (proton exchange membrane) electrolyzers, fuel cells, and humidifiers—essential systems for hydrogen production and use. The membranes are also applicable in redox flow batteries, with simultaneous development for lithium-ion and sodium-ion batteries.
Ion Membranes operates on a business-to-business (B2B) model. It generates revenue by selling its advanced ion exchange membranes and separators to other businesses that integrate these components into their own products and systems. The company also engages in research and development (R&D) collaborations with academic institutions, which not only enhances its product offerings but also opens up additional revenue streams through joint projects and grants.
The company has received several accolades, including TTGV Climate Tech Challenge and the 2023 Falling Walls Lab Turkiye 1st Ranking. These awards highlight Ion Membranes' commitment to innovation and excellence in the field of ion exchange technology.
In summary, Ion Membranes is a forward-thinking company that addresses critical needs in the green energy market through its advanced ion exchange membranes. Its focus on R&D and academic collaboration positions it well for future growth and technological advancements. By leveraging synergies and innovation, their aim is to "pioneer the revolution of membrane technologies".
