PEI film used for hydrogen energy
The transition to renewable energies and the reduction of greenhouse gas emissions are among the greatest challenges of our time. The hydrogen economy, in particular, plays a central role in this. Green hydrogen – produced by electrolysis of water using renewable energy – is considered a key factor for a climate-neutral future.
In this innovative environment, PEI (polyetherimide) film opens up new possibilities. Its unique properties, such as high-temperature stability, chemical resistance, and electrical insulation, offer decisive advantages in various applications related to hydrogen technology.
Green hydrogen – three categories
In current specialist literature and at international conferences, green hydrogen is divided into three categories:
- Renewable hydrogen: directly coupled to renewable energies and obtained from water by electrolysis.
- Low-carbon hydrogen (blue hydrogen): based on natural gas, where CO₂ emissions are reduced through carbon capture and storage (CCS).
- Carbon-neutral hydrogen: generated by electrolysis using grid electricity and is CO₂-neutral.
PEI film can particularly demonstrate its advantages in the field of green hydrogen.
Application areas of PEI film in hydrogen technology
- Hydrogen separation membranes
Thanks to its high temperature resistance and good gas separation properties, PEI film is suitable as a material for membranes for the separation and purification of hydrogen. - Membrane electrodes in electrolysis cells
In hydrogen production via electrolysis, PEI film can be used as a component of membrane electrodes. Its chemical resistance and reliable electrical insulation make it a valuable material. - fuel cells
Electrolyte films are used to convert hydrogen into electrical energy. PEI film contributes to the efficiency and service life of the cells through its temperature stability and material properties. - Hydrogen storage and transport
PEI film can be used in the interior lining of hydrogen tanks or containers, thus increasing safety during hydrogen storage and transport.
Summary
Dr. Dietrich Müller GmbH offers PEI films, a high-performance material that supports the path to a sustainable hydrogen economy. Whether in electrolysis cells, fuel cells, or hydrogen storage – PEI films make a valuable contribution to the technologies of the future.
