Insights

Financial Analyst

TL;DR Expanded regional bunkering partnerships strengthen distribution and support growing demand for low-carbon methanol.

Methanex is extending its physical delivery footprint through local bunkering partners, which reduces logistical frictions for ship operators switching to methanol. Taking over prior OCI/UniBarge arrangements and adding TankMatch for inland barge-to-ship operations plus South Korea last-mile partners increases regional coverage without necessarily requiring immediate capital-intensive asset builds. The emphasis on standardized safety protocols and Waterfront Shipping experience is important to limit operational and reputational risk during scale-up.

Industry Specialist (Maritime Fuels)

TL;DR Operational partnerships and safety guidance are crucial to accelerating methanol adoption in busy trade corridors.

Partnering with vetted local bunkering operators and leveraging a decade of methanol-fueled tanker operations provides practical capability to deliver fuel reliably and safely. The announcement signals a focus on logistics and compliance—critical factors for shipowners evaluating fuel-switching. The transfer of OCI-era arrangements into Methanex's global supply chain simplifies market access for customers in the affected regions.

METHANEX LAUNCHES GLOBAL METHANOL BUNKERING OPERATIONS WITH STRATEGIC PARTNERSHIPS IN THE ARA REGION AND SOUTH KOREA

VANCOUVER, British Columbia (September 23, 2025)–Methanex Corporation (TSX:MX) (Nasdaq:MEOH), the world's largest producer and supplier of methanol, today announced new strategic partnerships in two of the world’s key fueling hubs—the ARA (Amsterdam–Rotterdam–Antwerp) region and South Korea. These agreements further advance Methanex’s leadership role in supporting the marine energy transition. In the ARA region, Methanex is partnering with TankMatch—a recognized regional expert in inland waterway fuel logistics—to provide safe, barge-to-ship methanol bunkering. This partnership builds on a previous bunkering arrangement between OCI Global and UniBarge, which Methanex took over through its acquisition of OCI, boosting its capacity to serve a wider range of marine customers in the area. In South Korea, Methanex is working with Alpha Maritime and Hyodong Shipping to enable last-mile bunkering operations.

“These partnerships allow us to safely and reliably fuel ships with methanol in two of the busiest global trade corridors that are pivotal to maritime decarbonization,” said Mark Allard, Methanex’s Senior Vice President of Low Carbon Solutions. “By leveraging our global supply chain with the expertise of trusted local bunkering operators, we now provide a fully integrated, end-to-end methanol fuel solution to support the maritime industry’s needs.”

All partners are thoroughly vetted to meet Methanex’s stringent operational and safety standards. Drawing on more than a decade of experience operating the world’s largest fleet of methanol-fueled tankers through its subsidiary, Waterfront Shipping, Methanex has also developed a comprehensive methanol bunkering safety package and technical guidance based on internationally recognized protocols to support shipping companies, bunkering operators and terminals adopting methanol as a marine fuel. This combination of deep expertise and a robust global logistics network ensures a safe, fully supported bunkering experience.

As the demand for low-carbon methanol is expected to rise sharply in the coming years, Methanex continues to take focused steps to expand reliable supply and help the industry meet tightening regulatory requirements.
