The H21 project aims to demonstrate the feasibility of using 100% hydrogen in a gas distribution network and as part of the layering of confidence to the stakeholders and the HSE, to provide this we require expert assistance and assessment on gaining an Exemption from our current gas safety case. Therefore, NGN have requested Pipeline Integrity Engineers (PIE) to undertake a review and assessment of the documents developed to identify any potential intervention areas within the assessment of documentation in relation to GSMR and Safety case exemption. A key point from this assessment is to identify any potential gaps within the assessment of documentation in relation to GSMR and safety case exemption in order to operate a 100% hydrogen converted natural gas network.
A successful trial has the potential for the role out of hydrogen as a form of energy for heating to those currently not connected to the gas grid. This could mean those financially not able to use natural gas to heat their home may be able to with hydrogen.
The outcome of this project has highlighted key areas where further investigations are required as we progress to the proposed Hydrogen village trials, these can be found within the report and the output table
The learning from this project has identified future projects around the GSMR and the network Safety Case to be further developed as we progress towards net zero and the 100% hydrogen village trials. These areas have not previously been considered as applicable and provide insight into areas of concern which may provide barriers as we progress to 100% hydrogen village trials.
Upon completion of this project, we will be delivering a number of follow-on projects that will address the areas of development identified in order to mitigate areas of concern and remove barriers, ultimately enabling us to deliver net zero and a 100% hydrogen village trial.
