CVC Fund, through JGC MIRAI Innovation Fund, has invested in MiRESSO, a startup developing low-temperature refinement technology for beryllium, pivotal for nuclear fusion energy.

Target Information: MiRESSO

MiRESSO is a startup focused on developing a low-temperature refinement process for rare mineral resources, specifically beryllium (Be), a material that serves as a neutron multiplier in nuclear fusion reactors. Beryllium is estimated to require approximately 500 tons per fusion reactor, yet the current global production is only around 300 tons annually. This shortfall raises concerns that it could become a significant bottleneck in the future proliferation of nuclear fusion energy.

The company is recognized by the National Institute for Quantum Science and Technology and has pioneered a novel low-temperature refinement technology. Traditionally, the process of refining beryllium ore requires heating to temperatures of about 2,000°C. However, MiRESSO’s innovative method utilizes chemical processing and microwave heating to dissolve beryllium ore at a significantly lower temperature of 300°C, all while maintaining atmospheric pressure. As a result, this approach offers remarkable cost savings and energy efficiency compared to conventional methods.
