Source pathway descriptionDirect air capture using electrolysis to fix atmospheric carbon dioxide into seawater and as a mineral. Electrolyzer unit uses electricity to split seawater into hydrogen and oxygen, then exposes it to atmospheric air to capture CO2, trapping it in dissolved bicarbonate ions and solid mineral carbonates. Hydrogen is captured and processed for clean fuel applications.
Storage descriptionGreenhouse gas locked away in dissolved bicarbonate ions and solid mineral carbonates for thousands of years in the ocean. Seawater returned to chemically comparable original state.
