Our entry markets are PEM Fuel cells 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 ion-exchange membranes play a vital role in enhancing the performance of clean energy systems, thereby ensuring the most efficient and cost-effective carbon-neutral energy sources for the future.
Our current focus is on cation exchange membranes
PEM Fuel Cells
Proton exchange membrane Fuel Cells are electrochemical energy conversion devices that utilize hydrogen and oxygen to generate electricity, with the only byproducts being heat and water. PEMFC's operate at relatively low temperatures and can quickly vary their output to meet shifting power demands. Typical applications are automobiles and stationary power production.
Flow Batteries
Flow Batteries are an excellent source for long term and large-scale energy storage due to the high cycling capabilities with minimal performance degradation. Typical applications for Flow Batteries are grid balancing, mini grids, energy storage for renewable energy production, telecom towers and shipping ports.

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:
Emergency backup power

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.
