The transition toward low carbon offshore oil and gas operations requires alternative fuels capable of reducing greenhouse gas emissions while maintaining operational efficiency. Among hydrogen carriers, liquid hydrogen (LH2) has emerged as a promising option due to its high volumetric energy density and compatibility with cryogenic transport systems. This study presents a systematic literature review of 36 peer reviewed publications, selected from 137 screened records using the PRISMA 2020 methodology, to evaluate the configuration and feasibility of LH2 supply chains for maritime and offshore applications, including dual fuel diesel (DDF) engines. The synthesis indicates that LH2 viability is strongly configuration dependent and shaped by the systemic interaction between liquefaction energy intensity, boil off gas losses, cryogenic infrastructure investment, transport distance, and terminal readiness. While LH2 demonstrates structural advantages for long distance maritime transport compared to compressed hydrogen and liquid organic hydrogen carriers, offshore deployment remains sensitive to scale alignment, logistics constraints, infrastructure maturity, and operational continuity requirements. The review highlights that LH2 should be interpreted as a conditional decarbonization pathway rather than a standalone technological substitute, emphasizing the need for an integrated offshore specific supply chain framework to ensure reliable and economically viable DDF based decarbonization. © 2026 The Author(s)
