Objectives This objective of this project is identify and characterise these future challenges in more detail and produce an Outline Technical Specification for gas composition analysis equipment operating with a proportion of hydrogen that may be needed on the future gas network. The specification will address such issues as: Possible future gas components including hydrogen and consideration of contaminants;Supply pressure and flow rate parameters;Speed of response requirements; Required accuracy;Likely future number and location of instruments;Required data and software interfaces;Expected environmental operating conditions;Requirements for safety performance (both Atex rating and safety critical control);Expected power requirements;Cost expectations;Operational requirements and constraints, failure modes and spares. The intention is that this technical specification can then be shared with industry to identify suitable equipment that is available for use on the network in the future and can be tested on demonstration projects such as HyDeploy. If such instrumentation does not exist then the technical specification is intended to stimulate development of such instruments through academic bodies such as NPL or commercial organisations. Completion of the task outlined above should produce an Outline Technical Specification of an instrument that will meet the future challenges of a gas supply system sourced from multiple supplies. The specification may be met by currently available instruments or it may be a blueprint for a new instrument from the analyser manufacturers. A major indication of success for this project will be an endorsement of the specification from all the potential users. In summary the key indicators of success are: 1) An Outline Technical Specification2) An endorsement from all the GDNs.
Abstract As we look to increasingly decarbonise the gas grid alternative forms of low carbon gas are coming to the fore. In particular BioSNG and Hydrogen are all worthy of note. This project looks to develop a technical specification for an instrument that is capable of measuring the CV of gas which contains a high proportion of Hydrogen within it. This instrument will be necessary for the HyDeploy NIC project run between NGGD and NGN. As well as the technical challenge of measuring hydrogen alongside a potentially ever changing composition of base gas components there are a number of other challenges that future gas composition instruments will need to address: ; Gas composition analysis instruments may become safety devices on the network and will act to control gas composition, especially hydrogen concentration, to known safe levels;; New sources of gas may bring contaminants into the network (e. g. siloxanes in bio-methane from sewage) which may need detecting at very low concentrations (ppm); ; The number of gas composition measurement instruments may need to increase dramatically from the limited number in operation at the moment to deal with the variable gas composition in different parts of the network;; The additional instruments may not be needed for billing and so could perhaps have a different specification;; New instrumentation will be required to interface with existing systems. Current PGC instruments use DANINT software to record the data and a future suitable interface to this software or any new software may be needed;; New instruments may be able to address the maintenance issues of managing carrier gases. Before Hydrogen can be deployed commercially, several barriers must be overcome, one of which is to ensure that there is an adequate instrumentation for fiscal and safety purposes which is approved. An instrument will hopefully be trialled on a network with a high content of hydrogen as part of NGGD and NGNs HyDeploy NIC project which will take place at Keele University in Staffordshire. To create a technical specification for a future gas analysis instrument the technologies currently exist needs to be understood and this will be predominately achieved by a literature review. When developing the specification a clear understanding needs to be obtained from the GDNs and other relevant key stakeholders about the requirements that need met by this new instrument. Once all this information has been assimilated a technical specification can be drafted for dissemination. This draft technical specification must be agreed upon by all the GDNs before it is finalised for release to the market.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
