A hydrogen ship is a hydrogen fueled ship, using an electric motor that gets its electricity from a fuel cell, or hydrogen fuel in an internal combustion engine.
A hydrogen-powered ship is a vessel that uses hydrogen as its primary source of energy, typically through fuel cells or hydrogen combustion engines, to achieve propulsion. These ships represent a significant innovation in maritime technology, aiming to reduce greenhouse gas emissions and dependence on fossil fuels. Hydrogen, as a clean energy carrier, produces only water vapor as a byproduct when used in fuel cells, making it an environmentally friendly alternative to traditional marine fuels like diesel or heavy fuel oil.
Norway is driving a significant technological shift in the marine industry with its ambitious goal to require all ferries, tourist boats, and cruise ships to operate with zero emissions in its World Heritage fjords by 2026. Leading the charge is Norled AS, a pioneer in adopting zero-emission technologies within its fleet of over 80 vessels.
Committed to achieving net-zero operations by 2040, Norled AS has been modernizing its fleet to incorporate more low- and zero-emission vessels. In 2015, the company launched the MF Ampere, Norway's first battery-powered car ferry, igniting an electric ferry revolution. Today, approximately 70 electric ferries operate in the country, showcasing the success of this initiative.
Ferries, with their smaller sizes and predictable routes, are well-suited for battery power. However, limitations in battery power density and charging times pose challenges for scaling up. To meet its ambitious fleet transformation goals, Norled continues to explore alternative zero-emission technologies, complementing its battery-powered solutions. [1]
In 2000, the 22-person Hydra ship was demonstrated, and in 2003 the Duffy-Herreshoff watertaxi went into service. 2003 saw the debut of Yacht No. 1, as well Hydroxy3000. [2] The AUV DeepC and Yacht XV 1 were shown in 2004. In 2005 the first example of the Type 212 submarine, which is powered underwater by fuel cells, went into service with the German navy. In 2006 the 12-person Xperiance was debuted, as well as the Zebotec. In 2007 both the 8-person Tuckerboot and the Canal boat Ross Barlow debuted, and in 2008 the 100-passenger Zemships project Alsterwasser went into service in Hamburg. Also, in 2009 the Nemo H2 and the Frauscher 600 Riviera HP went into service. [3] In 2013 the Hydrogenesis Passenger Ferry project went into service. [4]
In February 2020 it was announced that the software tycoon Bill Gates had commissioned the world's first hydrogen-powered superyacht, in a £500m signal of his belief that investment in new clean technology is the best way to cut carbon emissions. [5] Later, the yacht manufacturers refuted this news and claimed that they have no business relationship with Gates. [6]
The custom build was said to be based on blueprints for a 112-metre design "Aqua" publicised in 2019 at the Monaco Yacht Show by the Dutch marine architects Sinot. [7]
The 80-car ferry MF Hydra sails in Norway, using 4 tonnes of liquid hydrogen, two 200 kW fuel cells, a 1.36—1.5 MWh battery, and two 440 kW diesel generators. The 80 cubic metre hydrogen tanks and the fuel cell are located on top of the ferry. The hydrogen is trucked from Leipzig in Germany. [8] [9] It sailed as a diesel-hybrid from 2022, and as a hydrogen-hybrid from early 2023. [10]
A wind turbine service vessel bunkered hydrogen in Netherlands in 2022. [11]
In November 2022, Approval in Principle (AiP) was granted by Nippon Kaiji Kyokai (ClassNK) for Kawasaki Heavy Industries's dual fuel generator engine using hydrogen gas as fuel, which will be installed on a 160,000 m3 liquefied hydrogen carrier developed by Kawasaki. Kawasaki intends to conduct a demonstration test of this engine after installing it on a large-scale liquefied hydrogen carrier which is planned to be commercialized in the mid-2020s. [12] [13]
In 2023, a 500 kW hydrogen ship sailed in China. [14]
In 2010, Hjalti Pall Ingolfsson from Icelandic New Energy has commented that ships are fast becoming the biggest source of air pollution in the European Union. He estimated that by 2020 emissions of sulfur dioxide and nitrogen oxides from ships will exceed land-based emissions in Europe. A big issue to be dealt with would be the storage of hydrogen on ships, assuming that there would be no opportunity to refill them when out at sea, [15] although one can use wind power and solar panels to generate electricity from the ocean while they are far from the shores and produce hydrogen, either onboard [16] or on ocean-borne stations. [17]
Hydrogen gas is already widely used in industrial processes and demand for it has increased dramatically over the last fifty years. Nearly all hydrogen is produced using fossil fuels. Six percent of global natural gas and two percent of coal currently goes to producing hydrogen. Hydrogen could be used to power ships with zero emissions from the ship itself, but producing the gas itself is not a low-carbon process if fossil fuels are used to produce it. [18]

The need for a hydrogen infrastructure varies, where the Yacht No. 1 was fueled by a mobile hydrogen station, [19] the prototype Haveblue Yacht XV 1 was intended to have onboard hydrogen generation, the Xperiance and Tuckerboot have exchangeable high-pressure hydrogen tanks which can be refilled at a local hydrogen station, the canal boat Ross Barlow uses fixed onboard low-pressure solid-state metal hydride storage tanks and depends on a refilling station on the waterside, the Zemships Alsterwasser refills at a fixed waterside storage tank with 17,000 liters of hydrogen which is refuelled by a compressed hydrogen tube trailer. [20] Offshore charging [21] and hydrogen production were under construction in 2022. [17]
Hydrogen codes and standards have repeatedly been identified as a major institutional barrier to the deployment of hydrogen technologies and the development of a hydrogen economy. To enable the commercialization of hydrogen in consumer products, new model building codes and equipment, as well as other technical standards are developed and recognized by federal, state, and local governments. [22] The Germanischer Lloyd guidelines for fuel cells on ships and boats [23] is used for the Hydra, Tuckerboot, Yacht No. 1, Zebotec and Zemships.

The NEW H SHIP project was a 15-month project that started February 2004. FC-SHIP was funded by the European Commission under FP5 - GROWTH from 2002 to 2004. The Viking Fellowship is a Nordic project. [24] The SMART H2 project started in 2007 by placing a fuel cell in the existing whale-watching ship Elding. [25] Other studies have also considered various ways of combining fuel cell operations on board with air conditioning systems for operations while in harbour. [26] In order to gain a commercial advantage, the Norwegian government scheduled money for a regular hydrogen car ferry in 2016, to be operational in 2021. New rules are viewed as more challenging than developing the technology. [27]
In early 2020, the e5 Project began to design a hydrogen cell and battery powered tugboat. [28]
A fuel cell is an electrochemical cell that converts the chemical energy of a fuel and an oxidizing agent into electricity through a pair of redox reactions. Fuel cells are different from most batteries in requiring a continuous source of fuel and oxygen to sustain the chemical reaction, whereas in a battery the chemical energy usually comes from substances that are already present in the battery. Fuel cells can produce electricity continuously for as long as fuel and oxygen are supplied.
An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators.
A hydrogen vehicle is a vehicle that uses hydrogen to move. Hydrogen vehicles include some road vehicles, rail vehicles, space rockets, forklifts, ships and aircraft. Motive power is generated by converting the chemical energy of hydrogen to mechanical energy, either by reacting hydrogen with oxygen in a fuel cell to power electric motors or, less commonly, by hydrogen internal combustion.
A zero-emission vehicle (ZEV) is a vehicle that does not emit exhaust gas or other pollutants from the onboard source of power. The California definition also adds that this includes under any and all possible operational modes and conditions. This is because under cold-start conditions for example, internal combustion engines tend to produce the maximum amount of pollutants. In a number of countries and states, transport is cited as the main source of greenhouse gases (GHG) and other pollutants. The desire to reduce this is thus politically strong.
A compressed-air vehicle (CAV) is a transport mechanism fueled by tanks of pressurized atmospheric gas and propelled by the release and expansion of the gas within a pneumatic motor.
A fuel cell vehicle (FCV) or fuel cell electric vehicle (FCEV) is an electric vehicle that uses a fuel cell, sometimes in combination with a small battery or supercapacitor, to power its onboard electric motor. Fuel cells in vehicles generate electricity generally using oxygen from the air and compressed hydrogen. Most fuel cell vehicles are classified as zero-emissions vehicles. As compared with internal combustion vehicles, hydrogen vehicles centralize pollutants at the site of the hydrogen production, where hydrogen is typically derived from reformed natural gas. Transporting and storing hydrogen may also create pollutants. Fuel cells have been used in various kinds of vehicles including forklifts, especially in indoor applications where their clean emissions are important to air quality, and in space applications. Fuel cells are being developed and tested in trucks, buses, boats, ships, motorcycles and bicycles, among other kinds of vehicles.
A hydrogen-powered aircraft is an aeroplane that uses hydrogen fuel as a power source. Hydrogen can either be burned in a jet engine or another kind of internal combustion engine, or can be used to power a fuel cell to generate electricity to power an electric propulsor. It cannot be stored in a traditional wet wing, and hydrogen tanks have to be housed in the fuselage or be supported by the wing.

Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems.
The 42' sailboat known as the XV/1 was intended to demonstrate Haveblue LLC's patented technology for the production, storage, and use of hydrogen on board a marine vessel. The anticipated range was to be a radius of ~300 nautical miles at 8 knots on a full tank.
A fuel cell bus is a bus that uses a hydrogen fuel cell as its power source for electrically driven wheels, sometimes augmented in a hybrid fashion with batteries or a supercapacitor. The only emission from the bus is water. Several cities around the world have trialled and tested fuel cell buses, with over 5,600 buses in use worldwide, the majority of which are in China.
In transportation, the original (2003) generic term "hydrail" includes hydrogen trains, zero-emission multiple units, or ZEMUs — generic terms describing rail vehicles, large or small, which use on-board hydrogen fuel as a source of energy to power the traction motors, or the auxiliaries, or both. Hydrail vehicles use the chemical energy of hydrogen for propulsion, either by burning hydrogen in a hydrogen internal combustion engine, or by reacting hydrogen with oxygen in a fuel cell to run electric motors, as the hydrogen fuel cell train. Widespread use of hydrogen for fueling rail transportation is a basic element of the proposed hydrogen economy. The term has been used by research scholars and technicians around the world.
A hydrogen internal combustion engine vehicle (HICEV) is a type of hydrogen vehicle using an internal combustion engine. Hydrogen internal combustion engine vehicles are different from hydrogen fuel cell vehicles. Instead, the hydrogen internal combustion engine is simply a modified version of the traditional gasoline-powered internal combustion engine. The absence of carbon means that no CO2 is produced, which eliminates the main greenhouse gas emission of a conventional petroleum engine.
The Hornblower Hybrid is a family of ferry boats belonging to US operator Hornblower Cruises, which are powered with hybrid power trains.
The principle of a fuel cell was discovered by Christian Friedrich Schönbein in 1838, and the first fuel cell was constructed by Sir William Robert Grove in 1839. The fuel cells made at this time were most similar to today's phosphoric acid fuel cells. Most hydrogen fuel cells today are of the proton exchange membrane (PEM) type. A PEM converts the chemical energy released during the electrochemical reaction of hydrogen and oxygen into electrical energy. The Hydrogen Research, Development, and Demonstration Act of 1990 and Energy Policy Act of 1992 were the first national legislative articles that called for large-scale hydrogen demonstration, development, and research programs. A five-year program was conducted that investigated the production of hydrogen from renewable energy sources and the feasibility of existing natural gas pipelines to carry hydrogen. It also called for the research into hydrogen storage systems for electric vehicles and the development of fuel cells suitable to power an electric motor vehicle.
Energy Observer, launched in April 2017, is the first vessel autonomous in energy thanks to a mix of renewable energy and renewable hydrogen produced onboard. Onboard hydrogeneration while sailing is possible, because 12 meter high Oceanwings have been mounted on the ship.
The e5 Project is a Japanese consortium with the purpose of developing renewably-powered commercial ships.
Zero Emission Industries, Inc. (ZEI) is an American hydrogen technology company founded in 2018 and headquartered in the San Francisco Bay Area. Previously known as Golden Gate Zero Emission Marine, ZEI designs and manufactures hydrogen fuel cell power systems and hydrogen refueling solutions with a focus on maritime applications.
MF Hydra is the world's first liquid hydrogen-powered ferry. Delivered in 2021, the 82.4-meter-long vessel can accommodate up to 300 passengers and 80 vehicles. It has two 200 kW fuel cells, two 440 kW generators, and two Shottel thrusters. It is able to move at a speed of 9 knots. With its 80 cbm hydrogen storage tank, the ferry is estimated to be able to reduce its annual carbon emissions by up to 95%. The vessel is operated by the Norwegian company Norled. The hydrogen is created with renewable energy in Germany and transported to Norway.
MV Sea Change is the first hydrogen fuel cell vessel in the United States and the first commercial fuel cell ferry in the world.
