There are over 4.5 billion tons of uranium in the ocean - 1,000 times more than on land.
Chinese researchers have innovated a new electrode material for electrochemical extraction designed to attract uranium ions from seawater more efficiently than current methods.
It is estimated that there are 4.5 billion tons of uranium in the ocean as dissolved uranyl ions, over 1,000 times more than on land. The new electrode extraction technology enables harvesting of low-concentration uranium from seawater, about 3 parts per billion, promising a stable and cost-effective uranium supply.
The next steps involve scaling up this technology for industrial use and reducing costs to compete with traditional mining. The method, while promising, still faces challenges in terms of efficiency and environmental impact mitigation.
The global reliance on a limited number of uranium mines, often in politically sensitive areas, has long been a concern. This breakthrough could redistribute the geopolitical power dynamics in energy resources.
