We are currently working actively towards the commersialisation of our ion-selective membrane, addressing two entrance markets Redox Flow Batteries and PEM Electrolysers. 

Redox Flow Batteries  

Redox Flow batteries are a form of large-scale energy storage which consists of two chambers holding the posolyte (Positively charges electrolyte) and the electrolyte (negatively charged electrolyte). The electrolytes are pumped through the system on separate sides of an ion-exchange membrane (Cellfion), an electrical current occurs through the membrane while both liquids circulate. Redox flow batteries are an excellent source for long term energy storage due to the high cycling capabilities with minimal performance degradation.  

Typical applications for Redox Flow Batteries are; grid balancing, mini grids, energy storage for renewable energy production, telecom towers and shipping ports.  

PEM Electrolyser  

Proton Exchange Membrane (PEM) electrolysers are used for green hydrogen production via a water splitting process called electrolysis. For this process, a catalyst, made up of two electrodes and an ion-selective membrane (Cellfion) is used to split water into hydrogen and oxygen which are held separate from each other due to the ion-selective membrane. There are currently 7 different methods for producing hydrogen, however, green hydrogen is the only method that is completely without the release of greenhouse gas emissions, due to the use of renewable energy sources to power the electrolysis plants. 

Typical applications for hydrogen are; Fuel cells, industry, energy storage, gas for residential and many more.  

What is an ion-selective membrane? 

An ion-selective membrane is the central component found in many electrochemical devices such as Fuel cells, Redox Flow Batteries and electrolysers. The membrane is often referred to as the heart of the cell as it is an important component in defining the performance of an electrochemical device.   

How does membrane work?   

The membrane is usually integrated between two electrodes (anode and cathode) and allows for only specific selected ions to be transported across it whilst blocking the unwanted molecules. An ion-selective membrane allows for specific ion selection through chemical modifications and size excursion created by the pores in the membrane.
