DNV wins three-year contract in the UK for the safe use and conversion of pipelines to transport 100% hydrogen

DNV, the independent energy expert and assurance provider, has been engaged to provide the necessary evidence to demonstrate the safe use and conversion of local transmission system (LTS) high pressure pipelines for the transmission of electricity. 100% hydrogen.

The gas distribution company SGN manages approximately 3100 km of LTS gas pipelines in the UK and leads this project in collaboration with the other UK gas networks.

The LTS is owned and operated by the gas distribution networks. These are the pipelines that connect the National High Pressure Transmission System (NTS) to the lower pressure levels. These pipelines are considered the “backbone” of the energy grid, currently delivering gas from NTS offtakes to towns and cities across the country.

Angus McIntosh, Director of Energy Futures, SGN, said: “The repurposing of the UK’s vast gas networks to transport hydrogen offers an exciting opportunity to deliver deep decarbonisation of the energy system. We are delighted to be working with DNV to undertake off-site testing at their Spadeadam factory. These tests are a key part of our overall program and will provide critical evidence to support our live demonstration of a 30 km gas pipeline conversion to hydrogen. The evidence and results will be representative and scalable for all local transmission assets in the UK, over 11,000 km of pipeline assets and associated plants.

DNV will provide key proof of safety and operation by carrying out a series of offline tests for this project at its remote research facility in Cumbria, North of England. The work program will demonstrate hot work on hydrogen lines, delayed ignition and overpressure testing, burst and fatigue testing, as well as exploring the hydrogen compatibility of fittings and existing pipe connections. As the project progresses, DNV will also support a live network SGN trial by studying the measurement and monitoring of a hydrogen pipeline (the volume of gas that can be “stored” in a gas pipeline), on a section of the local transport network.

Hari Vamadevan, UK and Ireland Regional Manager, Energy Systems at DNV, said: “In the UK’s recently published Energy Security Strategy, hydrogen is labeled as a premium fuel. The UK intends to lead the way in the development of hydrogen as a key domestic energy carrier, indeed recently doubling its ambition to 10GW of low-carbon hydrogen generation capacity from by 2030. The existing infrastructure is in place and SGN is making a huge push to accelerate the UK’s progress towards net zero.

DNV is uniquely positioned to host the offline LTS Futures trial at its state-of-the-art research facility alongside the FutureGrid project for National Grid Gas and the H21 project for Northern Gas Networks. DNV has demonstrated its commitment to the energy transition in general and hydrogen research in particular by investing in the construction of the HyStreet house terrace – used to demonstrate how hydrogen can be safely distributed for heating and cooking in typical British homes.
