Hydrogen Logistics Architecture Standard Version 1.01 (HLASv1.01) - A Deterministic Architecture for Bankable Hydrogen Infrastructure

The transition toward hydrogen-based energy systems has accelerated globally; however, the development of hydrogen infrastructure remains fragmented, project-centric, and often misaligned with long-term network efficiency and scalability requirements. Existing approaches typically focus on isolated production facilities, point-to-point logistics, or technology-specific solutions, resulting in suboptimal infrastructure utilization, higher delivered costs, and increased risk of stranded assets.

This paper introduces the Hydrogen Logistics Architecture Standard (HLAS), a deterministic, system-level framework for designing scalable and bankable hydrogen infrastructure networks. HLAS is grounded in formal analysis of endogenous network formation and proposes that optimal hydrogen systems emerge as multi-echelon, hierarchical architectures consisting of centralized production hubs, direct supply to large industrial users, regional aggregation hubs, and distributed demand layers. The framework separates topology selection from transport modality, enabling infrastructure planning that remains robust across evolving technologies and market conditions.

HLAS formalizes architecture classification, topology rules, structural constraints, and a deterministic evaluation framework for assessing system coherence. It further introduces a structured approach to investor triage and project evaluation based on architecture quality rather than isolated project metrics. By prioritizing aggregation, hub-based planning, and phased backbone emergence, HLAS minimizes total system cost while preserving scalability and interoperability.

The standard provides a practical bridge between theoretical network optimization and real-world infrastructure planning, offering governments, developers, and investors a consistent basis for decision-making. HLAS has implications for industrial cluster development, hydrogen corridor planning, export-oriented infrastructure, and capital allocation strategies.

By shifting the focus from individual projects to integrated network architecture, HLAS aims to establish a common reference framework for the design, evaluation, and governance of hydrogen infrastructure systems.
