How it Works
Our innovative technology is based on water electrolysis without needing a membrane. It involves separating hydrogen and oxygen gases using cryogenics later in the process rather than at the start. This approach provides flexibility in applications as oxygen and heat can be harvested by re-engineering the primary product (hydrogen).
Our unique and patented technology has attracted considerable interest as a disruptor in the hydrogen production sector from large-scale liquefaction projects for heavy-duty transport, aviation, and wastewater purification. Hydrogen is considered the future fuel for transport, such as fuel-cell electric vehicles, trains, and shipping. It is also used for heat and power in buildings and as industry feedstock.
The CPH2 solution is environmentally sustainable because it uses reusable components and does not require Platinum Group Metals for membranes or catalysts. To create sustainability, you must be sustainable.
How does the electrolyser work?
- Incoming water (1) is mixed with electrolyte and travels to the stack (2) where the chemical reaction happens, and the mixed hydrogen and oxygen gas is generated.
- The mixed gas continues its journey through the balance of the plant to the dryers (3).
- The wet gas enters the dryers, where desiccant removes the water from the mixed gas stream, and the gas continues its journey to the Cryogen for separation (4).
We separate the mixed gas in the cryogenics systems using cold temperatures, which liquefies the oxygen and leaves pure hydrogen as a gas. The cold hydrogen and liquid oxygen return through a patent-protected three-stream heat exchanger, which receives the incoming mixed gas, and the oxygen regasifies.
As the hydrogen exits as a gas, it performs a crucial pre-cooling function on the incoming gas. By the time the mixed gas reaches the bottom of the heat exchanger, the oxygen has already transitioned into a liquid state. The separated gases then proceed through the purity meters.
