Applications
Our entry markets are PEM Fuel cells, PEM Electrolyzers and Flow Batteries with potential application areas including filtration, printed electronics, super capacitors and other battery technologies.
Energy storage and energy conversion
The transition to replace fossil fuels with renewable, green energy has been moving at an unprecedented rate in the last decade. However, the expansion of the renewable energy industry doesn’t come without its challenges - especially where energy storage is concerned.

Intermittent renewable energy, such as wind and solar, require a means of storing energy, since the sun isn’t always shining and the wind isn’t always blowing. Rapidly emerging technologies in the form of Flow Batteries and Hydrogen can provide the perfect solution, where energy can be stored and discharged upon demand. Materials such as our bio-based, PFAS-free, ion-exchange membranes play a vital role in enhancing the performance of clean energy systems, thereby ensuring the most efficient, sustainable and scalable carbon-neutral energy sources for the future.
Our current focus is on cation exchange membranes

Fuel Cells
A Fuel Cell is composed of an anode, cathode, and an electrolyte membrane. A typical Fuel Cell works by passing hydrogen through the anode of a fuel cell and oxygen through the cathode. At the anode site, a catalyst splits the hydrogen molecules into electrons and protons. The protons pass through the dense electrolyte membrane, while the electrons are led through an external circuit where their energy is utilize, generating an electric current and excess heat. At the cathode, the protons, electrons, and oxygen combine to produce water molecules.  As there are no moving parts, fuel cells operate silently and with extremely high reliability.

Typical applications for Fuel Cells are:
Vehicles
Aviation
Industry
Emergency backup power
Energy storage
Flow Batteries
Flow Batteries are a form of large-scale energy storage which consists of two containers holding the posolyte (Positively charges electrolyte) and the negolyte (negatively charged electrolyte).

The electrolytes are pumped through the system into the stack where the ion are separated and transported through the membrane (Cellfion).

Flow Batteries are an excellent source for long term energy storage due to the high cycling capabilities with minimal performance degradation. 


Typical applications for Flow Batteries are:
Grid balancing
Energy shifting (Storing renewable energy)
Telecom towers
Shipping ports.
Electrolysis
Electrolyzers
An electrolyzer is comprised of three fundamental components: an anode, cathode, and an electrolyte membrane. This device operates on the principle of electrolysis, which involves the separation of water into hydrogen and oxygen. Much like its counterpart, the fuel cell, an electrolyzer facilitates this process by utilizing electrochemical reactions within its structure.The operation of an electrolyzer commences as water is fed into its anode compartment. Here, a catalyst aids in the decomposition of water molecules, causing them to split into protons and electrons. The protons, being positively charged, readily move through the electrolyte membrane, while the electrons are directed through an external circuit. This circuit harnesses the energy of the electrons, generating a flow of electric current and releasing excess heat in the process. On the cathode side of the electrolyzer, a complementary set of reactions takes place. Similar to fuel cells, one of the remarkable attributes of electrolyzers is their absence of moving parts, which enables them to function silently and with extraordinary reliability.
Typical applications for Electrolyzers are:
Hydrogen for Transportation
Aviation
