systems, and managing operational uncertainties all under tight cost, schedule, and performance constraints. This is compounded by scrutiny from ongoing commercial viability assessments and long-term operability expectations, in addition to the need to comply with policy and regulatory frameworks. In a world where CCS is increasingly being asked to scale, getting the delivery right is collaboration is non-negotiable : Projects thrive when stakeholders across the value chain – from technology providers, plant owners, and commercial offtakers – work shoulder-to-shoulder from design through to performance testing. • Successful delivery is critical for success : Demonstration units need to deliver to expectations, requiring a flawless execution strategy and plan to allow the technology to shine without cutting corners and mistakes in execution. • Modularity is crucial, but does not mean simplicity : Crucial for rapid deployment of a demonstration unit, but skid-based systems still require tailored integration into live plants. The deployment of Carbon Clean’s Case study: Carbon Clean’s CycloneCC deployment Complexity must be embraced and converted into opportunity, supporting projects from early design through to operations, including Carbon Clean’s advanced CycloneCC deployment at a nitrogen fertiliser plant in Abu Dhabi. The project, situated within the nitrogen fertiliser facility, involved a modular, skid- mounted carbon capture system that employs proprietary amine solvents combined with rotating packed beds to dramatically reduce plant space. After around 4,000 operational hours, the system exceeded performance expectations safely and with full transparency throughout. Several learnings from this and similar projects stand out: • No shortcuts on collaboration, end-to-end

as critical as getting the chemistry right. The emphasis must shift from “Can we capture carbon?” to “Can we do it reliably, modularly, and cost-effectively at site level meeting all stakeholder expectations?” That is why early demonstration is so important. Across the industry, we are seeing first-generation plants being delivered not just to prove the science, but to prove the execution • Engineurs’ contribution : Engineurs supported commissioning and operations, leveraging its efficient execution work processes and digital platforms to manage and document activities and coordinate across teams. • Key outcomes : • ~ 4,000 operating hours • Achieved TRL 7 • Met the demonstration unit performance benchmarks • Delivered with full auditability for investor scrutiny CycloneCC in Abu Dhabi is more than a technical win – it is a model for future rollouts. • Project context: Located within an existing fertiliser production facility, this was a test of modular carbon capture in an operating environment. This project is clear evidence that industrial CCUS is not only possible – it is deliverable.
