RH3OVA Limited

RH3OVA Limited is a UK-based joint venture between the United Kingdom Atomic Energy Authority (UKAEA) and Eni. The company delivers specialist consultancy and operational services to the global fusion industry, with a focus on the deuterium-tritium fuel cycle. Services encompass end-to-end support from feasibility studies to deployment and operations, including the supply of digital process models validated with fusion-relevant data.

RH3OVA addresses tritium production, use in energy generation, recovery from exhaust gases, and refinement for reuse. It draws on UKAEA expertise from the Joint European Torus and three decades of tritium operations. The venture builds on prior collaboration, including the H3AT Tritium Loop Facility, and aligns with UK fusion strategy and Eni’s fusion development goals.
