The transition from natural gas to hydrogen is an important technical priority for National Gas – and is critical to the delivery of net zero for the UK. FutureGrid is providing vital insights into hydrogen transportation and blending – to support the full-scale conversion to hydrogen.
Leading the way in the transition to hydrogen
As the UK prepares for the transition to hydrogen, it’s vital to demonstrate that the National Transmission System (NTS) and existing gas pipelines and assets can operate safely with hydrogen.
That’s why we have created the FutureGrid high-pressure test facility at DNV Spadeadam to carry out a wide range of essential hydrogen tests. Purpose-built using recently decommissioned NTS assets, this micro-transmission network allows us to carry out extensive tests in a secure offline environment, replicating every part of the gas transmission system. These tests will enable us to assess the effects of hydrogen on our pipes and assets, and on the operation of the network.
The aim of FutureGrid is to develop processes and safety standards that will allow us to run a safe and reliable national hydrogen transmission network. The outcomes of FutureGrid will inform the development and design of Project Union.
Phase 1: Facility
The FutureGrid high-pressure test facility at DNV Spadeadam is a world-first. It has been used to demonstrate that the pipelines and assets of the gas National Transmission System (NTS) could be used safely and reliably to transport hydrogen gas.
The FutureGrid test programme initially focused on evaluating the performance of key gas transmission assets with hydrogen. These assets included valves, filters and pipework. The phase 1 test programme assessed the performance of these assets in varying network conditions and with different blends of hydrogen and natural gas. We carried out tests using blends of 2%, 5% and 20% hydrogen with natural gas, as well as 100% hydrogen.
Tests were carried out in our purpose-built offline test facility, as well as in stand-alone test modules. These stand-alone tests included:
- Material permeation testing
- Pipe coating and cathodic protection testing
- Flange testing
- Asset leak testing
- Rupture testing
The phase 1 testing helped us to understand the similarities and differences in the behaviour of hydrogen and natural gas – so we can develop appropriate safety standards and procedures.

Our project partners
The scale and complexity of the net-zero challenge requires extensive cross-industry collaboration. The Phase 1 FutureGrid project was supported by specialist contributing partners:
DNV: our main delivery partner, responsible for building the test facility and developing a comprehensive test plan across the range of decommissioned assets.
Northern Gas Networks (NGN): collaborating on the project to build closer links with the H21 project, which is building a distribution test facility at the test site.
HSE Science Division: supporting the development of the test facility and master test plan, providing technical assurance and validation.
Fluxys: the Belgian gas transmission operator is contributing substantial hydrogen research, to support international collaboration.
Durham University: sponsoring a secondment student to study NTS asset gaps, focusing on developing skills and training courses along with Phase 2 of FutureGrid.
University of Edinburgh: supporting the trials and developing technical papers and research from the project, to enable dissemination. Linking H100 activities and FutureGrid/H21 activity to prevent duplication.

FutureGrid is open for business
Now that we have completed our own extensive trials of hydrogen and blended gases at the FutureGrid site, this high-pressure network of decommissioned pipelines and assets is available for use as a testing base by our partners. Any network operators, asset managers or other third parties can now book the facility to carry out their own tests on assets and novel technologies.
Please email us at [email protected] to find out more about the facilities available and how you could use them for your testing programmes.

Testing Guide
Phase 2: Deblending
Our ground-breaking deblending project is helping the UK prepare for the transition to cleaner, greener energy – testing ways to separate hydrogen from blended gases for use in vehicle fuelling.
During the transition to 100% hydrogen on the NTS, we expect that hydrogen will be blended with natural gas. Our deblending project focuses on separating gases within the NTS so that hydrogen can be supplied for transport fuelling applications.
Without deblending technology, hydrogen vehicles will only be able to refuel using locally produced hydrogen, until the national gas network switches to 100% hydrogen. That will restrict the rate at which the transport industry can decarbonise.
Our novel deblending project will showcase the full process, from separating blended transmission gases using electrochemical processes, through to refuelling hydrogen vehicles. The project will also develop low-cost mobile solutions for deblending and purification that can be deployed around the UK.
Our vision for the future is that businesses could connect to the NTS to extract hydrogen for refuelling stations for road vehicles, rail or bus depots, or for use in the marine and aviation sectors.
Our deblending project partners
FutureGrid deblending project is supported by these specialist partners:
DNV: an energy consultancy and research organisation which operates the Spadeadam testing and research site. Responsible for construction, commissioning and testing for the project.
HyET Hydrogen: a manufacturer of electrochemical hydrogen purification and compression systems, based in the Netherlands. Responsible for manufacturing the deblending and purification systems used in the project.
Element2: develops hydrogen refuelling stations (HRS) in the UK and is supplying the HRS for the project, as well as a number of test vehicles.
ERM: an energy consultancy, evaluating the market requirements for hydrogen refuelling to develop a deployment strategy for these systems.
Phase 2: Compression
Paving the way for a national hydrogen transmission system, our pioneering compression project is testing the performance of gas compressors with hydrogen to develop an asset fleet that’s fit for the future.
Gas is currently moved around the NTS at high pressure by a complex compression system, comprising more than 60 individual compressor units (mostly industrial versions of jet engines) at 21 compressor stations. The NTS is the only gas network in Great Britain with compression. Many of the compressors used are hydrogen-ready, but it’s vital to test these alongside all other assets to ensure the whole network can perform reliably with hydrogen.
The FutureGrid Compression project aims to demonstrate that the existing compressor fleet can be modified cost effectively to work with hydrogen. We will test a decommissioned gas turbine with different blends of hydrogen up to 20%, and then modify it to test with 100% hydrogen. This will give us the information required to repurpose our current compressor fleet. We will then carry out offline testing of the full compression system in a range of hydrogen scenarios.
The aim is to evaluate the capability of rotating machinery and the full compression system when operating with hydrogen – supporting the development of a wider compression strategy for the core hydrogen transmission network.
