It was only in 2010 that Evonik launched SEPURAN ® Green , its first membrane , which has revolutionised biogas upgrading . Since then , the SEPURAN ® family of hollow-fibre membranes has grown substantially and now includes modules for the separation , recovery and / or purification of many other gases , including hydrogen . The company ’ s latest product is the flatsheet anion exchange membrane DURAION ® for the next generation of electrolytic hydrogen production . To learn more about these innovations , we spoke with Goetz Baumgarten , Vice President of Membranes at Evonik .
