Technology group ABB Marine and Ports on Wednesday (1 December) said it has signed a Memorandum of Understanding (MOU) with Maritime Partners LLC (MP), Elliott Bay Design Group (EBDG) and e1 Marine to develop a hydrogen-powered inland towboat for operation in the U.S.
ABB and its industry partners aim to develop Hydrogen One, an ultra-low emission long-range towboat able to run for multiple days between fuelings.
The groundbreaking project is also a U.S. first for a fuel cell powered towboat, representing a major milestone in advancing environmentally friendly workboat operations in the U.S. and beyond. ABB provides the full electrical propulsion plant including power and energy management, automation and integration of fuel cell and battery power.
The 27-meter towboat Hydrogen One designed to push barges along inland waterways, is intended for deployment on the vast 14,500-mile waterway network that extends from the Port of New Orleans, operating along the Mississippi River and its many tributaries.
Hydrogen One will be able to travel with a load for about four days at the speed of 6 miles per hour, covering approximately 550 miles before the need to refuel. The vessel’s propulsion system will be capable of generating up to 2,700 HP propulsion power, with 1,700 HP generated by fuel cell and the remaining 1,000 provided by the battery.
The vessel will be operated by Maritime Partners, a New Orleans-based owner of close to 550 towboats, barges and other maritime assets.
The innovative towboat will convert methanol to hydrogen directly on board, deploying a hydrogen generator by e1 Marine, which converts a mixture of methanol and water into fuel-cell grade high-purity hydrogen, it states.
Hydrogen generated by this process will be fed into the fuel cells to generate electricity.
Onboard hydrogen production will eliminate complexities typically associated with direct fueling and storage of hydrogen.
The approach results in no particulate matter emissions and less than 80 percent CO2 emissions compared to an electrolyser solution using electrical power derived from fossil fuel sources. If methanol comes from a renewable energy source, the energy chain can be carbon-neutral.
Methanol is currently available as a bunker fuel at many terminals and is easy to handle and store. It can be transferred to the vessel in a manner similar to conventional fuels and does not need to be stored under pressure.
Towboats, tugs and other service vessels are increasingly coming under scrutiny for their alignment with environmental agendas. Traditional towboats operate with the main engines and generators engaged at all times, which often means poor utilization of onboard power and increases the fuel consumption. With an electric system, fuel cells and batteries can provide just the right amount of power exactly when it is needed.
Having pioneered the development of integrated power systems for a variety of ship types and marine fuels, ABB will provide the full electrical propulsion plant for the vessel, including electric motors, transformers, as well as the integration of fuel cells and batteries. ABB’s award-winning Onboard DC Grid™ power distribution system will ensure that the fuel cell and battery output is delivered to the towboat’s subsystems in the most optimal way.
The overall power setup will be controlled by ABB’s Power and Energy Management System (PEMS), which will also increase fault tolerance and provide a high degree of reliability while ensuring the maximum lifetime for the batteries.
“As a leading provider, lessor and financier of towboats, tank barges and other workboats, we see this groundbreaking project as a major opportunity to advance sustainability in workboat operations in the U.S. and beyond,” said Austin Sperry, COO of Maritime Partners.
“For fuel cell deployment along one of the most extensive inland waterway networks in the world, commitment from a partner overseeing 550 towboats is an excellent place to start.”
Fuel cells turn the chemical energy from hydrogen into electricity through an electrochemical reaction. The fuel cell technology is widely considered as one of the most promising solutions for supporting the shipping industry’s decarbonisation agenda and meeting International Maritime Organization’s targets to reduce annual emissions by 30% by 2025.
“We can make a real difference to efficiency and sustainability in the workboat sector, and have a transformative impact on air quality given that these vessels often operate close to centers of population. With this technology, we can offer U.S. shipyards, as well as state and federal agencies, significant support on their journey towards more sustainable operations,” said David Lee, Senior Account Manager, Commercial Vessels, ABB Marine & Ports.

‘We are happy to sit down with interested parties to discuss this opportunity, and share more details of our business regarding STS transhipment and storage with potential clients upon request,’ states Managing Director.
Top three positive movers in 2021 were Hong Lam Fuels Pte Ltd (+14); Sirius Marine Pte Ltd (+12); and TFG Marine (+11); according to the latest data from the Maritime and Port Authority of Singapore.
Webinar will offer delegates insights on the prevention of operational issues when using VLSFOs, along with an update on biofuels and bunker fuel quality trends for 2021 and its forecast for the current year.
Heating VLSFOs to prevent cold flow issues causes issues related to distillate ageing, and there is a gentle balance to be maintained when handling the product.
Research into n-paraffin distribution of VLSFOs has shown that they not only differ from MGO, but significantly differ from each other as well, states bulletin.
