CCUS Innovation 2.0 competition: MONET - MOF-based negative emissions technology

DESNZ·report·LOW·18 May 2026·Updated 18 May 2026·source document

Summary

DESNZ has published Key Knowledge Deliverables from Promethean Particles' MONET project, a pilot-scale carbon capture rig using Metal Organic Framework solid sorbents, funded under the £1bn Net Zero Innovation Portfolio CCUS Innovation 2.0 programme. The released documents (D3.3 build and D4.1 installation) are factory and site acceptance test verification sheets for a prototype unit tested on Drax's flue gas stream at its CCUS Incubation Site in May 2025. The substantive deliverables (CAPEX/OPEX technoeconomic analysis, lifecycle assessment) are listed as pending release after redaction.

Why it matters

This is grant-funded R&D housekeeping, not a market or rule change: it documents that a prototype rig was built and installed, with no cost, performance, or capture-rate data disclosed. The hidden cost is the public funding line itself: a £1bn innovation portfolio dispenses capital on technology-readiness milestones rather than on demonstrated cost per tonne abated, so the metrics that would let anyone judge value (the redacted TEA and LCA) are exactly what is withheld.

Memo

MONET - MOF-based negative emissions technology Project lead: Promethean Particles Limited The project involved the design and fabrication of a prototype carbon capture unit that utilised Metal Organic Frameworks ( MOFs ) as the novel solid sorbent. It was tested at Drax’s CCUS Incubation Site to demonstrate the separation of carbon dioxide from Drax’s industrial flue gas stream. A Lifecycle Assessment ( LCA ) and Technoeconomic Analysis ( TEA ) were also conducted within this project, based on the data collected from test trials at Drax.

The document is reflective of the status of the project at the time of writing. The material presented could have been subject to change as the project matured. These documents should not be considered a full representation of the final project. Summary of KKD D3.3 – Build of CCS Rig This deliverable report demonstrates the successful build of the MONET testing unit, through a variety of post-construction verification checks and factory acceptance testing (FAT) evidence. Final output will be documents demonstrating the successful build of the rig, including test data demonstrating theoretical operation in line with design specification, and detailing a plan for Drax integration.
