Carbon Dioxide (CO₂) and Hydrogen gas (H₂)

Vantris Energy provides transport solutions for Carbon Dioxide (CO₂) and Hydrogen gas (H₂) through onshore and offshore pipelines. Our wholly owned subsidiary, Peritus International (www.peritusint.com) boasts a team of experts specialising in pipeline transport solutions for CO₂ and H₂. Our collective experience and understanding of the specific issues which occur when existing or new pipelines are required to transport H₂ or CO₂ allows us to seamlessly navigate all project stages, from initial design to successful construction. With a proven track record in designing and implementing pipeline systems, including rigid and flexible pipelines, we excel in diverse environments, from shallow to ultra-deep waters reaching depths of up to 3500m. Our comprehensive approach extends to specifying subsea facilities and infrastructure, ensuring robust and efficient gas transport solutions.

Vantris Energy has extensive CO₂ and H₂ pipeline design capabilities, comprising all design stages. We ensure clients meet their technical requirements by providing solutions in transporting their CO₂ and H₂ gases.

    • (PIPEFLO) and transient multiphase (OLGA)
    • Product flow related issues such as ensuring CO₂ remains in the optimum phase
    • System operability design including simulations for steady state flow, planned start-up/shut down, emergency shutdown and other unplanned scenarios, and HIPPS studies
    • Preparation of operating and maintenance manuals

Confidential Client - Hydrogen Pipeline

Client is considering transporting hydrogen from a Gas Terminal to an underground gas storage facility off the UK coast via an offshore pipeline. They are also considering the potential to transport hydrogen from the gas storage facility to tie in with the Hynet pipeline network via onshore and offshore pipelines. Peritus’ scope is to undertake a feasibility study and initial conceptual design of the pipeline system including sizing and materials selection, to determine suitable initial routes for the pipelines and undertake a cost estimate and risk analysis.

Aramis Project – CO₂ Pipeline

The Aramis project, a collaboration between TotalEnergies, Shell, Energie Beheer Nederland (EBN), and Gasunie, aims to make a significant contribution to the energy transition by reducing CO₂ emissions for the hard-to-abate industries, and has been designated as a Project of Common Interest (PCI) by the European Commission. It is a high-priority initiative for achieving an interconnected energy system infrastructure in the EU.

Peritus, renowned for offshore pipeline and subsea engineering expertise, will design the 200km trunkline, leveraging  previous experience with CO₂ pipeline systems in the North Sea. 

Petrofac, a leading energy industry service provider, will lead a consortium which includes Peritus and Offshore Independents. Petrofac will be responsible for overall project management, system engineering, design of jacket and topsides of the Aramis distribution hub, subsea spurline system, and integrated control system. Offshore Independents will handle landfall design, bringing valuable in-country knowledge and technical know-how, particularly for the  congested Rotterdam port area.  The FEED will be executed collaboratively by all three companies from Petrofac’s Working UK office.
