Global Brain has invested in MiRESSO, Co., Ltd. (MiRESSO), a company aiming to implement fusion into society through stable supply of mineral resources, through its JGC MIRAI Innovation Fund L.P. (JGC MIRAI Innovation Fund).

Fusion reactor operation in several systems, including the mostly used Tokamak type, requires large amounts of beryllium (Be) as a component material for the fusion reactor blanket. However, the price of beryllium is currently very high, and since more beryllium is needed per reactor than is currently produced in the world, a supply shortage is anticipated in the future.

MiRESSO is a fusion startup certified by the National Institutes for Quantum Science and Technology (QST), and the company realizes beryllium purification at an overwhelmingly low cost and reduced energy consumption through its low-temperature purification technology. MiRESSO aims to become a company that contributes to implementing fusion into society as well as securing stable supply of mineral resources from the perspective of economic security by expanding its technology to refining of other minerals and materials that require high temperature processing.

Global Brain has decided to invest in MiRESSO, highly recognizing its know-how and technological capabilities for heating a mixture of beryl ore (raw material for beryllium) and reagents, and also hoping for the success of its excellent management team, the company’s impact on the fusion market, and market potential. Global Brain will contribute to the business growth of MiRESSO in cooperation with the JGC Group.
