| Objectives | The project will include a literature review of the impacts of hydrogen on coating performance adhesion and CP polarization. The literature review shall research hydrogen pipelines currently in operation, codes and standards and any research undertaken on the impact of hydrogen on pipeline coatings and cathodic protection. Hydrogen permeation through steel to include, but not limited to, grades X52, X60, X70 and X80 Factory applied and field applied coatings Pipeline pressures & flows Concentration of hydrogen in hydrogen-methane blend (% H2) Temperature CP currents and polarisation Below ground and/or above ground pipelines The literature review will be undertaken by an industrial partner and academic partner, with workshops held to share learning to ensure comprehensive research is undertaken which is relevant to the pipeline industry.The project will identify gaps in knowledge to enable NGGT to develop the scope of work required to determine the effects of transporting various hydrogen blends in the NTS on the coating and cathodic protection systems currently used for transporting natural gas. Data Quality Statement The project will be delivered under the NIA framework in line with OFGEM, ENA and NGGT internal policy. Data produced as part of this project will 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. The aim of the project is to understand the impact of hydrogen on coatings and CP systems. A literature review will be undertaken with academic and industrial partners to achieve the following objectives:Work Package 1 – Industrial Partner (ROSEN) – 4 months Review research undertaken with regards to coatings and cathodic protection of hydrogen pipelines o Hydrogen permeation through steel to include, but not limited to, grades X52, X60, X70 and X80 o Factory applied and field applied coatings o Pipeline pressures & flows o Concentration of hydrogen in hydrogen-methane blend (% H2) o Temperature o CP currents and polarisation o Below ground and/or above ground pipelines Benchmarking Standards Review Gap Analysis Status Updates Collaborative Workshops o Two workshops Work Package 2 – Academic Partner (WMG) – 4 months Review research undertaken with regards to coatings and cathodic protection of hydrogen pipelines o Hydrogen permeation through steel to include, but not limited to, grades X52, X60, X70 and X80 o Factory applied and field applied coatings o Pipeline pressures & flows o Concentration of hydrogen in hydrogen-methane blend (% H2) o Temperature o CP currents and polarisation o Below ground and/or above ground pipelineso Impact of and on coating defects (holidays) Benchmarking Standards Review Gap Analysis Status Updates Collaborative Workshops o Two workshops Work Package 3 (ROSEN & WMG) – 1 month Project Standard reportingo Technical final reporto ENA closure report The key objectives of the hydrogen impact study are: To understand the likelihood and extent of pipeline external coatings being exposed to hydrogen through permeation of steel from current available research and literature. To understand any research which has been undertaken globally with regards to the impact of the transportation of hydrogen on cathodic protection systems and coatings. To understand the coatings and corrosion control systems currently implemented on hydrogen pipelines worldwide including a review of global standards and policies for the transportation of hydrogen, highlighting industry type and acceptance criteria. To identify gaps in current knowledge to enable a suitable testing programme to be developed to determine the suitability of current coating and cathodic protection systems utilised on the NTS for the transportation of hydrogen. | |
| Abstract | The project will research the impacts on coating performance adhesion and Cathodic Protection (CP) polarization for the transportation of hydrogen and hydrogen blends in the NTS.A literature review will be conducted considering hydrogen pipelines currently in operation, codes and standards and any research undertaken on the impact of hydrogen on pipeline coatings and cathodic protection. The literature review will identify knowledge gaps in the coating and cathodic protection of hydrogen pipelines to develop further work required to determine the effects of transporting various hydrogen blends in the NTS on the coating and cathodic protection systems currently used for transporting natural gas. | |
