Oxford Sigma proudly participated in and sponsored the 32nd IEEE (Institute of Electrical and Electronics Engineers) Symposium on Fusion Engineering (SOFE 2025), held at the Plasma Science & Fusion Center, Massachusetts Institute of Technology (MIT), Cambridge, MA, USA, from 23rd to 26th June 2025. This premier international conference brought together global leaders in fusion science and engineering to share the latest advancements, foster collaboration, and accelerate the commercialisation of fusion energy.
As a globally recognised leader in fusion materials science and engineering, Oxford Sigma made a significant impact at this year’s symposium. Our team delivered a series of technical oral presentations and poster sessions that highlighted our pioneering research, innovative engineering solutions, and our unwavering commitment to enabling the next generation of fusion power systems.
Our contributions addressed critical areas in the path to commercial fusion, including:
- Qualification of lithium ceramic breeders for tritium breeding systems,
- Fusion-specific pressure codes and standards to ensure safety and regulatory readiness,
- Tungsten supply chain analysis for scalable reactor deployment,
- Liquid metal engineering for high-performance cooling and breeding systems
These initiatives address key challenges in the commercialisation of fusion energy. These efforts reflect Oxford Sigma’s mission to provide the materials technology and regulatory frameworks essential for building safe, efficient, and scalable fusion power plants.
In addition to our technical contributions, Oxford Sigma was also a proud sponsor of SOFE 2025, reinforcing our dedication to supporting the global fusion community and advancing the field through collaboration, knowledge sharing, and innovation.

“SOFE 2025 was a fantastic opportunity to share the progress we’ve made in qualifying lithium ceramic breeders for fusion blanket systems. Our work is laying the foundation for reliable, and scalable tritium breeding technologies, an essential technology for fusion power plants.”
Dr. Alasdair Morrison, Chief Technology Officer at Oxford Sigma
“It was exciting to catch up with colleagues from across the industry and present our work on developing high-temperature liquid lithium systems. Developing robust liquid metal technologies is a key step toward realising practical fusion power plants, and SOFE provided a great platform to exchange ideas with the global community. “
Dr. Bradley Young, Materials Lead at Oxford Sigma
Oxford Sigma remains committed to advancing the materials technology and engineering standards necessary for the realisation of commercial fusion energy. We thank the IEEE and SOFE organisers for hosting another impactful event and look forward to continued collaboration with the global fusion community.
