Kelton demonstrates transmission-scale hydrogen metering is feasible for the HyNTS project.
The HyNTS (Hydrogen Network Transmission System) programme is a UK initiative focused on repurposing the existing gas transmission network to transport hydrogen, supporting the UK's transition to a hydrogen economy.
Key to transporting hydrogen is accurately measuring significant volumes of Hydrogen on and off the network, and managing the energy balance of a Hydrogen network, as is done for a natural gas network.
In partnership with National Gas and DNV, Kelton contributed to the design and construction of a dedicated skid at National Gas’s FutureGrid facility, to test high pressure and high flow hydrogen meters.
Metering of up to 30% hydrogen is possible with small changes to current systems but 100% hydrogen required a new metering system. Using a prototype Coriolis meter calibrated for the process conditions, the team tested across a range of flows and pressures.
Impact
The project successfully demonstrated that transmission scale hydrogen metering is possible using a range of metering types. The project also highlighted areas for further study, including supplementing gas quality data with velocity of sound measurements and the benefits of different measurement techniques.
- Tested the transmission of hydrogen across a range of flows and pressures
- Successfully shown the feasibility of transmission scale hydrogen metering
- Completion of the wider project will unlock the potential of hydrogen to deliver the UK’s 2050 net zero targets.
D2Zero is at the forefront of the energy transition. We are meeting the dual challenge of decarbonising traditional energy sources, whilst accelerating the transition to renewable energy.
