Gas Network Hydrogen Testing Facility
A multipurpose facility suitable for testing gas network
assets and appliances in the presence of hydrogen
HSE's Gas Network Hydrogen Testing Facility is the world's first
gas network testing facility capable of working with 100% hydrogen,
purpose-built by Northern Gas Networks for Phase 1a of their H21
project but now available for other work.
Key features
- 3 gas banks (hydrogen, methane and nitrogen)
- 4 test bays
- Variable pressure range including Low Pressure (LP, 19-75
mbar), Medium Pressure (MP, 75 mbar-2 bar) and Intermediate
Pressure (IP, 2-7 bar)
- Flow meters for measuring gas flow and leakage
- Integrated sensors for temperature and pressure
- H2, O2 and CH4 gas
analysers
- Safety controls, including gas and flame detection
- Dedicated control room
Main applications
The Gas Network Hydrogen Facility was used extensively for NGN's
H21 project, a suite of gas industry projects
designed to demonstrate that the gas network can safely transport
hydrogen in the future. Phase 1a was designed to test a range of
assets, taken from gas distribution networks across Great Britain,
to provide quantifiable evidence that the UK distribution network
of 2032 will be comparably as safe operating on 100% hydrogen as it
currently is on natural gas.
The project reported in May 2021.
