NZTC Leverages OGC Energy Expertise for Successful Hydrogen Backbone Project


Net Zero Technology Centre




The Hydrogen Backbone Link (HBL) project is a key component of the Energy Transition Fund (ETF) Net Zero Transition Technology Programme (NZTTP). As part of the first phase of the HBL project, the focus was on a comprehensive valves and materials study (Scope 9). The goal of this study was to determine the most advanced and appropriate valves and materials technologies for the safe and efficient transport of hydrogen. The results of the study aimed to inform future investment decisions and de-risk the production and distribution of green hydrogen.


NZTTP's hydrogen backbone project played a critical role in advancing the use of hydrogen as a clean energy source and supporting the transition to a more sustainable future. The valves and materials study was crucial in providing valuable insights to support this mission. However, determining the most advanced and appropriate valves and materials technologies for hydrogen transport posed a challenge.

How OGC Energy helped NZTC

OGC Energy, a leading company in the field of materials for clean energy solutions, was tasked with carrying out Scope 9: Valves and Materials Study. Through a comprehensive review of the current valves infrastructure and design codes, as well as a focused failure modes, effects, and criticality assessment (FMECA), OGC Energy was able to evaluate the compatibility of current valves for hydrogen transport. The study estimated the potential leakage rate of valves using hydrogen as the service fluid and evaluated the environmental impact of these leaks. New technologies addressing these concerns were researched, and a technology roadmap was produced.
The results of the study showed that current valves used in natural gas infrastructure are suitable for hydrogen gas transport service, with new designs providing lower fugitive emissions. The FMECA assessment identified potential risks related to hydrogen stress cracking and wear on the valve seals, which were addressed through the development of new technologies. The study concluded that current valve materials are compatible with hydrogen transport. However, there was a lack of guidance for the repurposing of existing valves for hydrogen service.
