L2M – Clean Hydrogen and Ocean Alkalinity Enhancement through Bipolar Membrane Electrodialysis

This project aims to advance a clean technology that uses an electrodialysis process to remove acidity from seawater while producing green hydrogen. Using seawater and renewable electricity, the system removes excess acidity, encouraging ocean carbon uptake. The result is de-acidified seawater capable of absorbing more carbon dioxide, while simultaneously producing green hydrogen as a valuable co-product. This approach addresses ocean acidification, accelerates the natural carbon cycle, and generates a carbon-free fuel. Our modular, cost-effective system can integrate with existing ocean infrastructure for scalable climate and energy impact. It has potential applications in hydrogen-intensive industries such as coastal refineries, desalination plants, green steel, and shipping. With Canada’s vast coastline, renewable energy potential, and leadership in clean technology, this project aligns with national priorities by combining climate restoration with clean energy production, supporting Canada’s net-zero ambitions.
