CEN Workshop on ‘Characterization and testing of membranes for gas separation applications’

The CWA describes a set of common procedures, methodologies and protocols to be applied when determining specific performance characteristics of gas separation membranes for various applications.

In a context where a successful Energy Transition is of utmost importance for the European Union, different European industries have a key role to play to reach the CO2-neutraly. Reduction and avoidance of emissions being an important aspect in controlling the Global Warming.

Gas phase separation is an essential technology in various industries that allows the supply of different gas streams, be it gas mixtures or purified gas streams.


Different solutions exist to separate gases from each other, and the membrane-based technology has gained in importance in the recent years as it has become a viable technology for various separation tasks in numerous industries (energy generation, environmental protection, chemical industry, refineries …).

In the field of membranes exist a wide variety of membrane materials and membrane applications that are usually characterized and tested using specific methods and protocols employed by manufactures and research institutions.


To realise the potential of gas separation membrane technology it is necessary to be able to select the right membrane for the given separation task. This entails a true comparability of reported performance and operating window data for membranes based on thorough testing.

The main objective is to provide a detailed set of common procedures, methodologies and protocols to be applied when determining characteristics of gas separation membranes that will allow for comparable and homogeneous results independent of the details of the instrumental infrastructure at the individual institutions.


The development of a CWA on Standardized Characterization and Testing of Membranes for Gas Separation Applications is proposed as there is the need to develop a methodology to select the appropriate membrane for a specific separation task. As consensus-based guidelines the CWA will define a detailed set of common procedures to determine specific characteristics of gas separation membranes under different operating conditions.


The CWA to develop is related to the INNOMEM project (funded by European Commission European Union's Horizon 2020 Research and Innovation Program under Grant Agreement N° 862330: https://www.innomem.eu).


The planned CWA is intended to be used by (potential) users, manufacturers, academic, research institutes, … and will be drafted during the INNOMEM project timeframe, that ends in November 2024.


The virtual kick-off meeting will be held on July 4th 2024. People interested to participate in the kick-off meeting can register using the form below.


All interested parties are invited to submit comments on the draft Project Plan using the commenting form below, to the Workshop secretary, Raquel MARTINEZ EGIDO (ramartinez@une.orgby June 30th 2024
