f HyNTS Pipeline Dataset SIF Project Discovery Phase: Final Report

HyNTS is a programme of work that seeks to identify the opportunities and address the challenges that transporting hydrogen within the National Transmission System (NTS) and Local Transmission System (LTS) presents. This will unlock the potential of hydrogen to deliver the UK’s 2050 Net Zero targets. The programme is being executed alongside other ongoing UK hydrogen initiatives such as National Grids Project Union and Cadent’s HyNet projects.
A key element of repurposing feasibility, and therefore central to the overall HyNTS initiative, is the requirement to have an improved understanding of the ‘fingerprint’ of pipeline assets prior to hydrogen injection. The Pipeline Dataset SIF project has two primary objectives:
♦ Defining and gathering the data necessary to ultimately facilitate repurposing of above 7 bar pipelines on the NTS and LTS
♦ Developing the tools and processes to store, align and visualise data
Split into 3 phases, the first ‘Discovery’ phase aims to develop the high-level data and data management requirements for repurposing as well as the current data availability across the NTS and LTS to meet these requirements. Subsequent Alpha and Beta phases involve detailed planning and subsequent execution of the data collection and data management activities identified in the Discovery phase.
The Discovery phase comprises four Workpacks as shown in the diagram below designed to cover the project objectives.
ROSEN and Cadent have partnered with National Grid (NGG) to deliver the Discovery phase. Close collaboration between NGG, Cadent and ROSEN has been required to conduct all Workpacks, particularly in terms of appraising the current data held and current Data Management arrangements within both organisations.
This report presents the findings from the Discovery Phase as well as providing recommendations to feed into shaping subsequent Alpha and Beta phase activities.
