China is immersed in a nuclear revolution and needs industrial amounts of Uranium. His solution: “fish” in the sea

China is one of the countries that is most promoting the adoption of renewable energy thanks to Great ‘farms’ and market saturation of solar panels. At the same time, they have approved the Construction of ten new nuclear reactors. It may seem a contradiction, but in the midst of a Strong commercial warit is another step in energy self -sufficiency, and to achieve it they will need tons of uranium.

Your solution? Squeeze the uranium of the seas.

Marine mine. The country account with 56 nuclear reactors and has between 25 and 29 under construction. This implies that they need a lot of Uranium and the problem is that they do not produce enough. HE esteem That, in 2023, China’s production was only 1,700 tons, 4% worldwide, and although they have strong reserves, they need more.

In turn, China imported Some 22,000 tons in 2024 and have begun to put solutions. In 2024 began The construction of the National Project of Uranium Nº1 in Ordos. It will become the largest uranium mine in the country and a few months ago They announced that had discovered another important site, also in Ordos. However, it still is not enough, so they have seen the sea.

Uranium fish. Because yes: there is uranium in the oceans. Its concentration is extremely low, about 3 micrograms per liter, but due to oceanic immensity, it is estimated that the total is 4.5 billion tons of uranium. There are a thousand times more uranium in the seas than in known land reserves.

Extract Uranium from the sea is not something new and, during the 80s, Japan led the development of marine uranium extraction techniques. The problem is that it is a complex and, above all, inefficient process. That is why researchers focus on active uranium collection methods‘dapando’ different materials to be able to extract more material per liter. It is also a expensive method, about ten times more to extract it from terrestrial sources.

Miraculous material. But this is where the Chinese team of the Frontiers Science Center For Rare isotopes of the University of Lanzhou enters. In a study published in NatureThey explain that the key to extracting more efficient marine uranium resides in the MOF, or metal-organic frameworks. It is a crystalline material composed of metal ions that are coordinated with organic elements to form structures of great porosity.

It is like an extremely efficient fishing network to catch small particles that, in the case of uranium, allows you to better separate this element from others to which it can be attached. The Chinese team has dopa with Dipniletinelo molecules and claim that this new DAE-MOF material allows an uranium absorption capacity of 588 mg per gram, according to the tests.

This involves an efficiency 40 times higher when separating uranium from metals and vanadium and has been tested both in simulated and real sea water.

Aim. The idea is now to create test extraction plants this year, with pilot plants on the tons scale for 2035 and with a continuous production by 2050. wait That China’s demand for uranium is more than 40,000 tons in 2040, so land mines in conjunction with these marine alternative sources are essential to achieve the goal.

Without a doubt, it is an advance in marine uranium extraction at a time when the rest of the players on this board are also found Looking for ways to get more out of the sea for energy independence at a time when buying to other countries He has put up legs. And the United States, of course, is also in that fight, with the US Department of Energy analyzing The technical, economic and environmental viability of large -scale uranium extraction in its waters.
