| Objectives | The research will be completed in phases of which this is the first phase and is strictly limited to a desktop exercise. We shall review any existing literature and available Equations of State to understand the potential error of measurement by introducing hydrogen blends. Future phases will investigate any changes required and implementing lab trials as proof of concept, if that is deemed necessary by the desktop review. Data Quality Statement (DQS): The project will be delivered under the NIA framework in line with the agreed Energy Networks Innovation Process document NGGT / NGET internal policies. Data produced as part of this project will be subject to quality assurance to ensure that the information produced with each deliverable is accurate to the best of our knowledge and sources of information are appropriately documented. All deliverables and project outputs will be stored on our internal SharePoint platform ensuring backup and version management. Relevant project documentation and reports will also be made available on the ENA Smarter Networks Portal and dissemination material will be shared with the relevant stakeholders. Measurement Quality Statement (MQS): The methodology used in this project will be subject to our suppliers own ISO 9001 certified quality assurance regime and the source of data, measurement process and equipment as well as data processing will be clearly documented and verifiable. The measurements, designs and economic assessments will also be clearly documented in the relevant deliverables and final project report and made available for review. A two part project is proposed and the first phase includes:1. Desk-top review of impact of hydrogen on calculated hydrocarbon and water dewpoints.a. Review of published data – use the GERG work as a starting point.b. Investigate the different EoS (GERG 2008, RKS, LRS, Peng Robinson and other options)c. Theoretical mixture analysis and also “real” gases – including links to ISO 23874 (Gas chromatographic requirements for hydrocarbon dew point calculation).d. Intercomparison of the calculated values focusing on error analysis and deviations with a view to developing a sensitivity analysis of the calculated dewpoints as a function of the EoS usede. Evaluation of the potential deviations and errors that may result for existing EoS options for natural gas if the method id changed to accommodate the presence of hydrogen2. ReportThe report will comprise: Results on impact of different EoS on wide range of gas mixtures from different entry points and with different hydrogen content Endorsement of EoS for hydrogen blends Overall estimate of uncertainties and errors Proposed next steps required to address the conclusions of part 1.The work is required to allow compliance with Gas Safety (Management) Regulations 1996 should we use the existing National Transmission System as the entry point for hydrogen blends. Specifically, Schedule 3, Regulation 8, Part 1 which states that HCDP and WDP: shall be at such levels that they do not interfere dewpoint with the integrity or operation of pipes or any gas appliance which a consumer could reasonably be expected to operate. The objective of this project is to complete a desktop review on the impact of hydrogen blends on hydrocarbon and water dewpoint. | |
| Abstract | This desktop study looks at the theoretical impact of hydrogen blends in conventional gas mixtures on hydrocarbon dewpoint and water dewpoint (HCDP/WDP). HCDP/WDP tell us when liquid drop out will occur. There is a requirement to monitor this under Gas Safety (Management) Regulations (GSMR) as the liquids can cause damage to National Transmission System (NTS) assets and downstream customers equipment e.g. Power Station turbines or Distribution Networks.HCDP/WDP is currently calculated by using a calculation which is not designed to include hydrogen mixes.The Distribution Networks do not check for HCDP/WDP as National Grid GT (NGGT) check at the entry point to the NTS only. The Distribution Networks therefore assume the gas is safe to transport and use as NGGT have checked it. | |
