100MW PEM electrolyzer to produce Hydrogen and Oxygen - IDENTIFIED BY INCITE

The electrolyser will be based on a state of the art 5MW PEM stack integrated into pre-engineered 20MW electrolyser trains, with factory assembled balance of plant to reduce the amount of bespoke work required to integrate electrolysers into new sites.

Technical Description of a Conceptual 100 MW PEM Electrolyser System:

System Design:

The system is conceptualized as a large-scale electrolysis plant capable of delivering a significant volume of hydrogen and oxygen gases for industrial applications or energy storage.
The plant architecture is modular, consisting of twenty individual 5 MW electrolyser stacks that are assembled to form four 20 MW units.
Electrolyser Stack:

Each 5 MW electrolyser stack comprises numerous individual cells connected in series. These cells each contain an anode, a cathode, and a PEM membrane.
The stacks are engineered for high efficiency and durability, designed to operate continuously under industrial conditions.
Each stack includes integrated cooling and control systems to manage heat and operational parameters.
Unit Integration:

The 20 MW units are built by integrating four 5 MW stacks with balance-of-plant (BoP) components, which include gas separators, heat exchangers, power electronics, control systems, and safety devices.
The design ensures that each unit can operate independently or in concert with the other units.
The integration allows for ease of maintenance and potential scalability, with the possibility of adding more units to increase capacity.
Operational Characteristics:

The electrolyser system operates at high pressures to minimize the energy required for hydrogen compression, which is essential for storage and transport.
The system is optimized for dynamic operation, allowing it to respond to fluctuating renewable energy inputs, such as wind or solar power.
Advanced control systems ensure the stability of the electrolysis process and the quality of the produced gases.
Gas Production:

The system is designed to produce hydrogen at a purity level suitable for various applications, including fuel cell vehicles, power generation, and industrial processes.
Oxygen, as a byproduct, is also captured and can be used in industrial applications or released safely into the atmosphere.
Safety and Monitoring:

The system includes comprehensive safety features to handle the reactive and flammable nature of hydrogen, as well as the high-pressure operating conditions.
Continuous monitoring and diagnostics are integrated to detect any leaks or operational anomalies, ensuring safe and reliable operation.
Energy Efficiency:

The overall system targets high energy conversion efficiency, minimizing the electrical energy required to produce a given quantity of hydrogen and oxygen.
Heat recovery systems can be employed to utilize waste heat, further improving the system's efficiency.
Scalability and Flexibility:

The modular design allows for the system to be scaled up by adding additional 20 MW units or scaled down by decommissioning units, depending on demand.
The system's flexibility also enables it to integrate with various energy sources, storage solutions, and end-use applications.
