Proxima Fusion is moving the supply chain forward to the key material stages. The company stated that it plans to invest 140 million euros in building a factory to produce high-temperature superconducting tapes for fusion reactors. This material will be directly used in the design of their reactors.
Factory Investment and Sources of Funds
Proxima Fusion said that the total investment in the factory is about 140 million euros, which is approximately equivalent to 162.6 million US dollars. The project will be advanced with a combination of public and private funds. Lower Saxony state will contribute 21 million euros.
Key materials are used in reactors.
Superconducting tapes can generate strong magnetic fields, which are used to confine the plasma required for fusion. The company stated that its demonstration plant will use 20,000 kilometers of superconducting tape, and the amount needed for commercial power plants will double.
Supplies are still concentrated in Asia.
At present, the vast majority of high-temperature superconducting tapes in the world are produced in China and Japan. Reports also mention that such materials have become a fundamental breakthrough for fusion startups over the past decade or so, and are also used by other companies to improve the efficiency and power density of data centers.
