WaterStation is a self-contained power generation system that produces and stores energy via water electrolysis and hydrogen fuel cells. Without external power supply, WaterStation utilizes renewable energy such as solar energy or wind turbine. Water obtained through purification treatment is used as a raw energy source, and hydrogen is produced through a water electrolyzer using solar cells. Our system purifies and stores the produced hydrogen, generates electric power through fuel cells, stores it in the storage system, and supplies electric power. In addition, through integrated monitoring, WaterStation can identify and detect power generation, stability, and product status.
