3. Safety & Environmental Compliance

Electrolyser operation is the heart of a solar-powered green hydrogen system. Its primary function is to split water into hydrogen and oxygen using renewable electricity from solar panels. Effective operation begins with ensuring high-quality feedwater, as impurities such as dissolved salts, silica, or metals can damage membranes and electrodes, reducing efficiency and lifespan. The electrolyser’s electrical input must be managed carefully, matching the variable solar output while maintaining optimal voltage and current for stable hydrogen production. Advanced systems often integrate energy management and SCADA controls to monitor production rates, adjust load dynamically, and optimize energy consumption, ensuring consistent hydrogen purity and yield. Regular monitoring of parameters like hydrogen flow, pressure, temperature, and purity is essential to detect anomalies early and maintain performance within the designed specifications.

Maintenance of the electrolyser focuses on preventing wear and ensuring longevity of critical components. Membranes, electrodes, and catalysts degrade over time and must be inspected periodically. Alkaline or PEM electrolysers require scheduled checks to clean or replace membranes, replace worn seals, and inspect electrical connections for corrosion or overheating. Water treatment systems, including reverse osmosis and deionization units, need routine cleaning and filter replacement to prevent scaling or fouling inside the electrolyser. Additionally, safety systems, such as pressure relief valves, hydrogen sensors, and ventilation, must be tested regularly to protect against leaks, overpressure, or abnormal operating conditions.

Preventive and predictive maintenance strategies are critical for ensuring continuous hydrogen production.
