Maritime decarbonization specialists Green Marine and tech firm MarinaChain have launched Verdaxis, an AI-powered digital platform designed to streamline alternative fuel procurement and complex regulatory compliance for the shipping industry. Initially operating out of Singapore with a focus on methanol and advanced biofuels, the joint venture bridges the gap between corporate net-zero targets and physical fuel availability across major global bunkering hubs.
Singapore | May 12, 2026 – As the maritime industry shifts from decarbonization rhetoric to strict regulatory execution, Green Marine Pte Ltd and MarinaChain Co Ltd have officially launched Verdaxis, a joint venture designed to streamline the sourcing, procurement, and compliance of low-carbon marine fuels.
Officially established on April 22, 2026, and headquartered in the global bunkering hub of Singapore, Verdaxis is an AI-enabled digital platform built to bridge the operational gap between ambitious corporate net-zero targets and the fragmented reality of alternative fuel availability.
The Digital Answer to Regulatory Complexity
With the tightening of FuelEU Maritime mandates, the widening scope of the EU Emissions Trading System (EU ETS), and impending International Maritime Organization (IMO) mid-term market-based measures, fuel procurement is no longer just about price per metric ton. It now requires rigorous sustainability verification, emissions tracking, and compliance workflows.
Verdaxis aims to solve this multi-layered problem by combining MarinaChain’s digital carbon-accounting architecture with Green Marine’s deep technical and engineering expertise in alternative fuel operations.
An AI-Enabled Marketplace for Alternative Fuels
A core pillar of Verdaxis is its proprietary, AI-driven marketplace model. Rather than acting as a standard brokerage, the platform utilizes structured matching algorithms to connect verified buyers and sellers based on highly specific criteria:
- Fuel pathways (e.g., bio-methanol vs. e-methanol)
- Port-specific availability windows
- Commercial pricing and volume requirements
- Regulatory and sustainability compliance certification
Initially, the platform will focus on ready-to-deploy transition fuels, specifically methanol, ethanol, and advanced biofuels.
“Shipping’s fuel transition is moving from strategy to execution,” said Fredrik Stubner, Founder, Partner, and CEO of Engineering at Green Marine. “Owners, charterers, and fuel suppliers need practical tools that connect verified supply, committed demand, compliance requirements, and operational readiness. Verdaxis was created to help close that gap.”
Key Features and Strategic Global Rollout
The platform’s suite of services goes beyond simple transaction matching, offering a holistic toolkit for energy transition managers:
- Compliance Integration: Built-in tools designed to calculate and verify compliance workflows for EU ETS and FuelEU Maritime.
- Market Intelligence: Real-time data feeds providing indicative pricing and supply availability insights across key ports.
- Operational Readiness: Digital training modules, bunkering technical support, and bespoke fuel transition advisory services.
While Singapore serves as the initial launchpad, the joint venture has outlined a phased expansion into the world’s most critical bunkering corridors. Verdaxis plans to roll out localized iterations of the platform in Rotterdam, Houston, Santos, and Shanghai as regional alternative fuel supply chains mature and global demand accelerates.
“MarinaChain’s strength is turning maritime regulatory complexity into usable digital workflows,” added Dan Ha, CEO of MarinaChain. “By combining that capability with Green Marine’s fuel and operational expertise, Verdaxis gives the industry a practical platform to evaluate, source, and execute low-carbon fuel opportunities with greater confidence.“
A Deep Dive into the Joint Venture Partners
Verdaxis is an AI-enabled digital platform supporting the maritime energy transition through fuel trading connectivity, compliance tools, market intelligence and operational support services. The launch of Verdaxis brings together two highly distinct but complementary sets of expertise within the maritime decarbonization sector. By fusing heavy “steel-and-fuel” operational experience with cutting-edge AI software compliance, the joint venture addresses both the physical and regulatory pain points of the energy transition.
Green Marine: The Alternative Fuel Specialists
- Core Focus: Maritime engineering, crew education, and green fuel supply chains.
- The DNA: Led by ex-Captains, Chief Engineers, and technical pioneers who co-invented early dual-fuel marine engine optimizations with MAN.
- Industry Standing: Green Marine is widely recognized as a premier authority in the methanol-as-a-marine-fuel value chain. They specialize in the design, construction supervision, and retrofitting of methanol dual-fuel vessels.
- The Operational Muscle: Green Marine is not just an advisory group; they actively manage the off-take, storage, and distribution of green fuels. They enter the joint venture backed by access to over 1 million tons of green methanol available to clients, with focused infrastructure footprints in major hubs like Singapore, Rotterdam, Shanghai, and Tianjin.
MarinaChain: The AI Regulatory Architects
- Core Focus: AI-powered carbon accounting and automated maritime compliance workflows.
- The DNA: Originally incorporated in South Korea, MarinaChain is an award-winning tech company that secured back-to-back recognition from OpenAI and the Korean Ministry of SMEs and Startups for its generative AI logic and Advanced General Intelligence (AGI) potential.
- Industry Standing: MarinaChain specializes in “turning maritime regulatory complexity into usable digital workflows.” Their flagship software automatically ingests complex operational shipping and fuel documents, transforming raw data into verified carbon lifecycle data required for international environmental compliance.
- The Software Muscle: MarinaChain has extensive experience building automated frameworks for localized port emissions target management and high-stakes international regulations. Their tech stack provides the compliance backbone for Verdaxis, ensuring transactions automatically align with the stringent data requirements of EU ETS and FuelEU Maritime.
The Collaborative Synergy
Rather than functioning as another pure-play software tool or a traditional, low-tech fuel brokerage, Verdaxis unites both halves of the modern bunkering equation. Green Marine provides the technical validation of alternative fuel pathways, physical fuel supply, and technical bunkering knowledge, while MarinaChain provides the automated compliance auditing and scalable AI architecture needed to execute transactions in a highly regulated landscape.
