PLS PVCR-1.0 Seawater Hydrogen: A New Scenario for PV Electrocatalysis | Perfectlight

1. Why Seawater

Freshwater electrolysis is limited by water resources, while seawater is virtually inexhaustible. Photovoltaic electrocatalytic seawater hydrogen production uses seawater and solar energy directly, avoiding freshwater consumption—an ideal route for coastal and island green hydrogen.

2. Positioning of PLS PVCR-1.0

The PLS PVCR-1.0 Solar Photovoltaic Electrocatalytic Seawater Hydrogen Production System couples PV power supply with seawater electrolysis, adapted to seawater's high salinity, side reactions, and corrosion—suited to coastal demonstration and research validation.

3. Technical Challenges

• Chlorine side reaction: chloride ions in seawater easily compete for oxidation, requiring electrode and potential control;
• Corrosion: the high-salinity environment demands more of materials and sealing;
• Catalyst stability: long-term seawater operation needs resistance to deactivation.

4. Application Prospects

Coastal PV electrocatalytic seawater hydrogen can couple with storage and chemicals to form off-grid green-hydrogen nodes. At the demonstration stage, pair with a power meter and gas metering to quantify real energy efficiency.
