Top 10 Green Hydrogen Projects: Air Products’ 1.2 M Tonne Deal, 4 GW Power, and Key Bunkering Hubs (2025 to 2026)

An analysis of the maritime sector’s pivot to alternative fuels reveals a clear, foundational strategy for 2025 and 2026: build the infrastructure first. The dominant trend is not yet widespread vessel conversion but a concerted global effort to establish large-scale green hydrogen and ammonia production hubs alongside critical port bunkering facilities. Key projects, such as the 1.2 million tonne per year NEOM initiative and Envision Energy’s pioneering green ammonia bunkering, demonstrate a strategic de-risking of the supply chain. This infrastructure-first approach, concentrated in major shipping regions like Northern Europe, the Middle East, and Asia, is creating the backbone for the future of hydrogen-based marine fuels.

Ammonia Bunkering, Envision Powers First Green Fueling Operation

The diversity of applications within these top projects signifies a multi-pronged approach to maritime decarbonization. While green ammonia is the clear frontrunner for long-haul shipping, other hydrogen pathways are being actively developed for specific use cases. The landmark first green ammonia bunkering operation in July 2025, using fuel from Envision Energy’s Chifeng plant, was a pivotal proof-of-concept for the entire supply chain. This is complemented by massive production-for-export projects like NEOM and Slagen, designed to feed future global demand. Concurrently, direct hydrogen is being proven for specific segments. The Sea Shuttle project deploys 3.2 MW fuel cells on container ships for short-sea routes, while the Klaipėda Port initiative focuses on producing hydrogen onsite for local port machinery and vessels. This parallel development indicates the industry is not betting on a single solution but is tailoring hydrogen-based fuels to different maritime needs.

Europe Leads Port Infrastructure, NEOM Anchors Middle East

Geographically, these projects are not random; they form a strategic map of future green shipping corridors. Northern Europe is emerging as a clear leader in building out the necessary port infrastructure, with interconnected projects in Norway (Slagen, LH 2 production), Lithuania (Klaipėda Port), Finland (Hy 2 gen), and the UK (Floating Power Hubs). This regional cluster approach aims to create a robust supply and bunkering network for vessels operating in the Baltic and North Seas. In the Middle East, Saudi Arabia’s NEOM project serves as a monumental production anchor, poised to supply green ammonia to both Europe and Asia. Further east, the comprehensive project in Singapore, involving Sembcorp and Mitsubishi, and India’s bunkering facility at V.O. Chidambaranar Port, signal a determined effort by Asia’s top maritime hubs to secure a leadership position in the alternative fuel transition.

1.2 M Tonnes Per Year, Green Ammonia Production Reaches Scale

The projects scheduled for 2025-2026 reveal a distinct split in technological maturity and commercial scale. Green ammonia production is rapidly moving from pilot to industrial scale. The NEOM project, with its 1.2 million tonnes per year capacity, and Envision’s operational 600, 000+ tonne facility represent a significant leap in commercial readiness. The Final Investment Decision (FID) for the Slagen project further validates that large-scale ammonia production technology is considered viable and bankable. In contrast, direct hydrogen applications, while promising, are at an earlier commercial stage. The Sea Shuttle’s hydrogen-powered ships and Norway’s focus on building a liquid hydrogen (LH 2) supply chain are pioneering efforts that are still scaling. Feasibility studies like the UK’s floating power hubs represent the earliest stage, exploring novel ways to integrate hydrogen into the port energy ecosystem.

Air Products’ Offtake Deal Signals an Infrastructure-First Strategy

The overarching signal from these top projects is a decisive move to solve the supply-side equation before mass demand from shipowners materializes. The industry is collectively focused on an infrastructure-first strategy to de-risk the energy transition for the maritime sector. The structure of the NEOM deal, where Air Products acts as the sole offtaker and partners with giants like Yara to distribute the product, is a template for future large-scale developments. It guarantees an outlet for the massive production volume, which in turn provides the certainty needed for such a capital-intensive project. Similarly, port authorities in Singapore, Lithuania, and India are proactively building bunkering facilities, sending a clear message to the market that the fuel will be available. This focus on building production hubs, pipelines, and port services in 2025-2026 is the essential groundwork that will enable the widespread adoption of hydrogen-powered vessels in the years to come.
