KII's Investment in MiRESSO: A Step Towards Sustainable Fusion Energy

KII's Strategic Investment in MiRESSO for Fusion Energy



In a significant move towards sustainable energy, Keio Innovation Initiative (KII) has invested in MiRESSO, a pioneering company focused on refining beryllium for fusion energy. This investment not only underlines KII's commitment to advancing innovative technologies but also marks a notable advancement in the quest for a stable supply of beryllium, an essential material for fusion reactors, which is currently facing a global supply shortage.

MiRESSO, headquartered in Misawa, Aomori Prefecture, is set to utilize this funding of approximately 4.23 billion yen to develop a pilot plant for beryllium production, significantly enhancing their production capabilities. The pilot facility, named BETA (Beryllium Testing plant in Aomori), aims to establish a reliable production system that leverages MiRESSO's groundbreaking low-temperature refining technology.

Addressing Challenges in Fusion Energy



The urgency for beryllium is becoming paramount as global developments in fusion energy continue to progress. Unfortunately, the shortage of beryllium, which plays a critical role as a neutron multiplier in reactors, poses a significant barrier to launching effective fusion projects. MiRESSO’s innovative process promises to revolutionize the traditional high-temperature refining approach of beryllium mineral resources. By implementing low-cost and energy-efficient methods, MiRESSO aims to offer a reliable and cost-effective supply of this critical element.

The implications of this technology extend beyond mere production. The successful application of MiRESSO’s low-temperature refining process is expected to facilitate the quicker implementation of fusion energy into society, thereby accelerating the transition to a decarbonized future. As nations seek sustainable energy alternatives, this advancement is anticipated to play a crucial role in combating climate change.

Future Development and Company Overview



With the newly acquired funds, MiRESSO is advancing towards the construction of the BETA facility. The design plans are actively being developed in Hachinohe city, also located in Aomori Prefecture. This facility is expected to serve as a cornerstone in establishing a sophisticated production framework for beryllium, reinforcing MiRESSO's position in the energy sector.

The establishment of MiRESSO in May 2023 positions it as a startup backed by notable entities like the National Institute for Quantum Science and Technology (QST), highlighting its credibility and innovation. Led by CEO Katsumichi Nakamichi, MiRESSO is on a mission to not only produce but also commercialize this vital resource, ensuring its availability for future energy endeavors.
