Reusing existing oil and gas infrastructure can lead to more cost-efficient deployment of CCS and hydrogen technologies and limit the costs of achieving EUs climate ambitions. The aim of the Re-Stream study wasto provide fact-based elements to this statement and to identify relevant infrastructure and define what technical adaptations and investments would be required to unlock its potential for reuse for both CO2 and 100% H2.
Carbon Limits and DNV performed the Re-stream study for Gas Infrastructure Europe (GIE), the European Network of Transmission System Operators for Gas (ENTSOG), the International Association of Oil & Gas Producers (IOGP) and Concawe, the scientific and technical body of the European Petroleum Refiners Association. All in all, 67 pipeline operators participated in the Re-Stream study, providing data for approximately 58,000 km of pipelines (+24,200 km assessed by operators themselves as suitable for hydrogen 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 project represents a significant portion of the oil and gas pipeline network in Europe.
