MASiP Phase 3 (Qualification Testing & Integrated System Development)

The MASiP Phase 3 is developing a new pipeline system to serve as an alternative to conventional steel pipelines in the transmission network. The material used in this pipeline will render it capable of transporting natural gas, biogas, and up to 100% hydrogen. Building on Phases 1 and 2, this phase focuses on the technical assessment of tight radius bends, tees, and damage repair, as well as the integration of live monitoring systems in a prototype operational environment.

Comprehensive validation will include connectors, coatings, repair systems, hot-tapping solutions, ground movement tolerance, durability, and design life testing. All testing will be carried out in accordance with IGEM, API, and ASME standards.

The key deliverable is a validated, deployable hydrogen-ready pipeline system that is safe, compliant, and cost-effective, offering potential cost savings of up to 50% compared with steel. The project outcomes will support the UK’s RIIO-GD2 strategy and 2050 net-zero targets by enabling hydrogen-ready infrastructure, improving monitoring, installation efficiency, and long-term reliability, while also providing the evidence base required for regulatory, policy, and industry acceptance of alternative pipeline materials.
