Hydrogen production is the industrial creation of hydrogen gas for later use as a feedstock, fuel, or process gas. It can be done through electrolysis, where electricity splits water, or through chemical and thermal processes used in large plants. In every case, the goal is the same: generate hydrogen at the right purity, pressure, and flow for technical use.
In cyber security, hydrogen production matters because it is often run by industrial control systems, sensors, valves, and programmable logic controllers. If an attacker changes setpoints, disrupts control logic, or tampers with alarms, production can become unsafe, inefficient, or unavailable. Defenders protect these environments with network segmentation, strong access control, monitoring of control traffic, and safety systems that can fail closed or keep critical equipment stable during a cyber incident.
