Onboard hydrogen production
АВВ Group working on a methanol-hydrogen fuel cell engine will supply an electric propulsion system with transformers and integrated fuel cells and batteries for Hydrogen One, the world’s first towboat powered by this type of fuel. Leasing company Maritime Partners expects it to ensure a higher sustainability and reliability of its fleet of towboats.
ABB Marine & Ports has signed a Memorandum of Understanding (MoU) with Maritime Partners LLC (MP, develops alternative marine fuels for workboats), Elliott Bay Design Group (EBDG, a firm of naval architects and marine engineers) and e1 Marine (specializes in hydrogen generation) to develop a hydrogen-powered inland towboat for operation in the U.S. ABB will become a technology partner for world’s first methanol-hydrogen fuel cell towboat. Hydrogen One, an ultra-low emission long-range towboat able to run for multiple days between fuelings.
According to АВВ Group, the project is a significant step in terms of popularization of environmentally friendly shipping worldwide.
About ABB: ABB Ltd, formerly ASEA Brown Boveri, is a Swedish–Swiss multinational corporation headquartered in Zürich, Switzerland, operating mainly in robotics, power, heavy electrical equipment, and automation technology areas. In 2020, ABB sold its Power Grids business to Hitachi.
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. 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.
The innovative towboat will convert methanol to hydrogen directly on board deploying a hydrogen generator by e1 Marine, which convert a mixture of methanol and water into fuel-cell grade high-purity hydrogen. Hydrogen generated by this process will be fed into the fuel cells to generate electricity, says the company.
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 will be operated by Maritime Partners, a New Orleans-based owner of close to 550 towboats, barges and other maritime assets.
“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.
“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,” said Austin Sperry, COO of Maritime Partners.
Onboard hydrogen production will eliminate complexities typically associated with direct fueling and storage of hydrogen. This 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, explain the experts.
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 decarbonization agenda and meeting International Maritime Organization’s targets to reduce annual emissions by 30 percent by 2025.
