The findings of the study may help address knowledge gaps by understanding the ability of onshore and offshore European infrastructure to carry hydrogen and CO2.
“The study’s findings are very promising” said Gaëlle Cauchois, Principal Consultant and Project Leader of the Re-Stream study at Carbon Limits “Re-Stream results are an important contribution to the ongoing policy discussions on hydrogen and CCS, and a solid base on which to carry out more targeted research”.
“The findings give infrastructure operators the confidence needed to undertake further research, testing and studies to assess specific conditions of individual pipelines for reuse, ultimately contributing to the transport of CO2 and hydrogen in Europe.” said Jørg Aarnes, Global Lead - Hydrogen and CCS, Energy Systems at DNV.
The European Commission underlined its interest in repurposing the EU’s existing pipeline infrastructure in the Hydrogen and Energy System Integration Strategies, but information on reusability was relatively scarce. The study’s purpose was to provide fact-based results on technical aspects and cost related information in time for the publication of the upcoming Hydrogen and Decarbonised Gas Market Package and Carbon Removal and/or carbon capture, use and storage (CCUS) Strategy. The data can help inform the upcoming regulatory work to scale up hydrogen and CCUS technologies in the EU.
The approach of Carbon Limits and DNV’s pipeline research team combined data collection and mapping of existing pipelines; identification of CO2 and hydrogen storage locations, potential CO2 emitters and hydrogen producers and users; assessment of the potential for pipeline reuse and identification of case studies for economic assessment; economic assessment of reusing existing pipelines compared to new build; identification of technical challenges and mitigation options to unlock the reuse potential.
