Oxford Sigma announces its participation in the Steering Committee supporting the Clean Air Task Force (CATF) International Working Group on the Materials Database for Fusion (MatDB4Fusion), a major global initiative to accelerate the development and deployment of fusion energy.
Dr Thomas Davis, Chief Executive Officer of Oxford Sigma, has been appointed as a member of the Steering Committee, which will provide strategic oversight and governance for the MatDB4Fusion platform.
MatDB4Fusion is a comprehensive, quality‑controlled database designed to centralise and standardise materials data for fusion applications. The platform enables the global fusion community to access, share, and analyse key material properties, including physical, thermomechanical, and chemical behaviour under extreme conditions such as neutron irradiation, transmutation, and plasma–material interactions.
Developed by CATF in partnership with the OECD Nuclear Energy Agency (OECD‑NEA), MatDB4Fusion addresses a long‑standing challenge in fusion materials science: the fragmentation and inaccessibility of critical data generated over decades of research. By providing a unified, high‑quality dataset, the initiative aims to support more efficient materials qualification, reduce duplication of effort, and enable advanced modelling and artificial intelligence applications.
From Oxford Sigma’s perspective, the formation of the Steering Committee represents an important step towards coordinated, international action on one of fusion energy’s most significant technical barriers.
The Steering Committee will guide the evolution of the database, ensuring that it remains aligned with global research priorities while upholding data integrity and usability. It brings together expertise from across industry, academia, and research organisations, reflecting the cross-sector collaboration required to realise fusion energy at scale.
Oxford Sigma’s involvement reflects its ongoing leadership in fusion materials development, qualification, and standards, including its work across international programmes and codes and standards initiatives. Participation in the Steering Committee further strengthens the company’s commitment to enabling the materials solutions required for next-generation fusion systems.

“Fusion will only move at the pace of its enabling technologies, and materials data is one of the foundations that underpins credible design, qualification, and deployment. MatDB4Fusion is an important step towards giving the global fusion community a more consistent, accessible, and high-quality basis for decision-making, and I am pleased for Oxford Sigma to contribute to that effort through the Steering Committee.”

About MatDB4Fusion
MatDB4Fusion, operated by CATF, is a comprehensive, quality-controlled database for materials used in the fusion energy sector. It offers a centralized platform to share, access, and analyze the physical, thermomechanical, and chemical properties of materials relevant to fusion device design, including fusion specific properties related to neutron irradiation, transmutation, plasma-material interaction, and others.
About Clean Air Task Force
Clean Air Task Force (CATF), within the international working group on materials database and in partnership with the Organization for Economic Cooperation and Development’s – Nuclear Energy Agency (OECD-NEA) as an international database host, launched MatDB4Fusion to empower the global fusion community with the data needed to design the next generation of fusion power plants.
