Do you believe bioethanol is a practical fuel alternative for the global shipping industry?
POET and Maersk have completed the first 100% bioethanol bunkering operation in the United States, utilizing existing marine infrastructure in Houston. This project tests the feasibility of using bioethanol to reduce emissions in the global maritime industry.
Why it matters
The operation demonstrates a viable path for the maritime sector to scale lower-emission fuels by leveraging existing supply chains and transportation infrastructure. For local logistics and shipping operators, it signals potential shifts in fuel procurement strategies as industry players look toward alternative energy mixes.
POET produces more than 3 billion gallons of bioethanol annually across 35 bioprocessing facilities. The company also maintains a position as the 11th-largest U.S. container exporter.
The players
POET
A major bioethanol producer operating 35 bioprocessing facilities with significant scale in the U.S. container export market.
Maersk
A global shipping and logistics integrator that provides vessel capacity and is testing new maritime energy solutions.
Kirby Corporation
A leading domestic tank barge operator and maritime services provider that manages complex fuel transportation and logistics.
Port of Houston
A major maritime port authority providing coordination and infrastructure for large-scale international shipping operations.
U.S. Coast Guard
The federal agency responsible for maritime safety and enforcing regulatory requirements for new fueling procedures.
The details
The operation relied on collaboration between Maersk, Kirby Corporation, the Port of Houston, and the U.S. Coast Guard to manage regulatory requirements and fuel transport. By using existing marine infrastructure, the group demonstrated that bioethanol can be integrated into current bunkering workflows without requiring entirely new handling systems. Kirby Corporation facilitated the transport, while the port provided the necessary staging and logistical coordination for the container ship bunkering.

Market Landscape
This bunkering test follows the pattern of industry-led pilots intended to meet broader international decarbonization targets. It marks a significant shift toward alternative energy in shipping, similar to how the industry previously adapted to meet mandatory low-sulfur fuel standards.
Operators should monitor whether bioethanol pricing becomes competitive with conventional marine fuels through future scale-up efforts. Firms involved in maritime logistics should watch for updated regulatory guidance from the U.S. Coast Guard regarding the expanded use of ethanol-based fuels.
The takeaway
The successful use of 100% bioethanol suggests that scalable, lower-emission fuels can be integrated into existing maritime infrastructure. Operators should watch for additional bunkering tests in major port hubs to determine if this becomes a viable cost-alternative to traditional marine fuels.
