High-power microwave systems for fusion energy commercialization
About MuWave
MuWave is a developer of high-power microwave technology, founded in 2023 by co-founders Steven Craig and Helen Webster. The company operates as a spinout from the United Kingdom Atomic Energy Authority (UKAEA), leveraging intellectual property and expertise developed within the national research body. This strategic spinout aligns with the UKAEA's goal of translating fusion research into commercial ventures to foster economic growth. The founding team consists of engineers from the UKAEA with specialized knowledge in microwave and industrial applications.
Read full description
The company's core business revolves around engineering and commercializing the next generation of high-power microwave systems, including microwave sources called gyrotrons. Its primary market is the fusion energy sector, where its technology is essential for heating plasma to extreme temperatures. MuWave's systems are positioned to be a key component for future fusion power plants, such as the UK's prototype STEP (Spherical Tokamak for Energy Production) fusion facility. Beyond fusion, MuWave targets a range of other industries by aiming to solve the "THz gap." Potential applications for its technology include satellite communications, radar, geothermal drilling, and medical imaging.
MuWave's business model involves the sale of products and services related to high-power microwave systems. The company secured initial pre-seed funding of £450,000 from the UK Innovation and Science Seed Fund (UKI2S) in a deal that also finalized its spinout agreement with UKAEA. This capital is intended to accelerate technology development, expand its product portfolio, and support global export plans. MuWave is headquartered at the Culham Campus in the UK, a hub for fusion research, and is actively working with the UK supply chain to source components for its technologies.
