f NGT Compressor Station FMEA for Hydrogen: FMEA Summary Report

The project between DNV and NGT innovation is exploring the future impact of introducing hydrogen into the National Transmission System (NTS) network and specifically looking at the impact on the compressor station equipment. The consequent failure modes associated with the introduction of hydrogen will be assessed through Failure Mode Effect Analysis (FMEA).
The work scope includes:
• Perform a staged approach FMEA study  Qualitative assessments determining the risk levels associated with the various components of the compressor trains.
• Perform the FMEA on each selected train type, assessing the operational, safety and environmental impact of H2 introduction.
Assessment has been made for two potential network gas types:
• 25% H2/NG blend
• 100% H2
The output is an FMEA on each generic compressor stations, indicating the risk areas from H2 operation. This output will allow NGT to identify areas which require further assessment / action before H2 is introduced.
This report was submitted to HSE for their assessment of the safety evidence for 100% hydrogen heating, which can be found at Hydrogen heating: HSE assessment of the safety evidence - GOV.UK.
