Capture and Storage (CCS) is critical to achieving net-zero targets. However, the long-term integrity of wells remains a major challenge, particularly in ensuring the reliability of storage infrastructure. Geological CO₂ storage is typically implemented through injection wells comprising steel casing and cementitious barriers. These materials are exposed to complex environments involving supercritical CO₂ and CO₂-saturated brines containing impurities, which can significantly influence corrosion processes, material degradation, and the performance of cement–steel interfaces. Such effects may ultimately compromise the long-term sealing of CCS systems.

As part of this role, you will join a major European consortium (SPECS) investigating the effects of CO₂ stream impurities on storage systems, working alongside leading universities, research organisations, and industry partners, including major energy companies across the UK and EU.

This role focuses on the experimental investigation and mechanistic understanding of degradation processes in cement–steel systems, directly contributing to the definition of safe impurity limits and material selection strategies for CCS wells. The project addresses the critical challenge of ensuring the durability and integrity of cementitious seals and cement–steel interfaces exposed to supercritical CO₂ containing impurities.

You will:

• Investigate degradation of steel-cement systems and study the interface with various steels and corrosion-resistant alloys (CRAs);
• Evaluate corrosion performance of steel-cement systems exposed to both clean and impure CO₂ compositions;
• Assess the integrity of cement–steel interfaces in CO₂–brine environments to help define safe impurity thresholds for CCS well materials.

We are open to discussing flexible working arrangements.
