Re-Stream – Study on the reuse of oil and gas infrastructure for hydrogen and CCS in Europe
The Re-Stream cross-industry study provides fact-based elements on the reuse of oil and gas infrastructure by identifying and assessing relevant infrastructure, and defining which technical adaptations and investments would be required to unlock its potential for re-use for both CO2 and hydrogen.
The study confirms the significant potential for reuse of oil and gas infrastructure in Europe for hydrogen and carbon dioxide transport: reusing existing oil and gas infrastructure can lead to more cost-efficient deployment of CCS and hydrogen, reducing the costs of the energy transition.
In Europe existing oil and gas infrastructure/pipelines are a strong asset on the pathway towards EU’s climate neutrality
Existing pipelines can be reused to transport CO2 for geological storage. The Re-Stream study identifies no technical showstoppers for transporting CO2 in the gaseous phase in Europe’s existing oil and gas pipeline – neither onshore nor offshore
Most of the offshore pipelines assessed can be used for transporting hydrogen
Onshore, close to 70% of the total pipeline length can be reused considering the current state of knowledge/standards. None of the pipelines analysed can be categorically excluded from reuse as of today

Data collection and mapping of existing pipelines in Europe
On 29 November 2021, study authors Carbon Limits and DNV presented Re-Stream to an online audience of 200 participants. The Member of the European Parliament Maria Spyraki delivered opening remarks, and the funding partners IOGP Europe, ENTSOG, Concawe and GIE delivered short remarks in an exchange moderated by Anne-Sophie Corbeau, Scholar at Columbia University’s Center on Global Energy Policy.
The study was commissioned by Concawe, the scientific and technical body of the European Petroleum Refiners Association, Gas Infrastructure Europe (GIE), the European Network of Transmission System Operators for Gas (ENTSOG), and the International Association of Oil & Gas Producers (IOGP Europe).
All in all, 67 pipeline operators participated in the Re-Stream study, providing data that could be analysed within the Re-Stream project for approximately 58,000 km of pipelines (+24,200 km assessed by operators themselves as suitable for H2 reuse) representing half of the total offshore pipeline length and approximately 30% of the onshore oil and gas pipelines. The quantity of pipelines covered in the Re-Stream study represents a significant portion of the onshore and offshore oil and gas pipeline network in Europe.
