Title : The great re-purposing: Retrofitting gulf midstream infrastructure for the global hydrogen and ammonia trade
Abstract:
Background:
As the global energy sector pivots toward a net-zero future, the Gulf region is uniquely positioned to transition from a hydrocarbon exporter to a global leader in Green and Blue Hydrogen. However, the massive capital expenditure (CAPEX) required to build entirely new transport networks remains a significant barrier. In 2026, with large-scale hydrogen projects across Saudi Arabia, the UAE, and Qatar nearing operational status, the technical challenge shifts to infrastructure optimization.
Objectives:
This presentation investigates the engineering and economic feasibility of "The Great Repurposing"—the conversion of existing crude oil and natural gas midstream assets for hydrogen and ammonia service. The study aims to provide a technical roadmap for utilizing legacy infrastructure to minimize environmental impact and maximize financial efficiency.
Methodology & Discussion:
The research focuses on three critical engineering pillars:
-
Material Integrity: Mitigating "Hydrogen Embrittlement" in legacy carbon steel pipelines. We analyze the efficacy of advanced internal polymer liners and epoxy coatings as a barrier between the hydrogen molecule and the steel lattice.
-
Terminal Conversion: Retrofitting LNG storage and export terminals into Ammonia hubs. Given the similarities in cryogenic requirements, we examine the modifications needed for sealants, pumping systems, and safety sensors.
-
Logistical Diversification: Modeling the transition from maritime-dependent exports to stable, trans-continental "Hydrogen Corridors." We compare the risk profiles of repurposed pipelines versus traditional shipping routes through maritime checkpoints like the Strait of Hormuz.
Conclusion:
The analysis demonstrates that retrofitting existing infrastructure can reduce initial capital requirements by up to 75% compared to new-build projects. By re-purposing the "steel beneath the sands," regional operators can maintain their role as the world's energy heart while leading the global decarbonization movement. This transition ensures that the Gulf remains a resilient energy hub, immune to the traditional vulnerabilities of maritime oil transit.
