A fuel cell coupled with an electric motor is two to three times more efficient than an internal combustion engine running on gasoline or diesel.
– Hydrogen can be produced using diverse, available renewable energy sources, (wind, solar, geothermal, and hydroelectric power)—using a wide range of processes. Siemens and NELS are but two companies leading innovation in this science
Hydrogen can be produced in small units where it is needed, such as vehicle refueling stations, in a manner known as “distributed production.“
Large central hydrogen production facilities (750,000 kg/day) that take advantage of economies of scale will be needed in the long term to meet the expected large hydrogen demand.
Semi Central Production
Intermediate-size hydrogen production facilities (5,000–50,000 kg/day) located in close proximity (25–100 miles) to the point of use may play an important role in the long-term use of hydrogen as an energy carrier. These facilities can provide not only a level of economy of scale but also minimize hydrogen transport costs and infrastructure.
DNV GL, recognized globally for quality assurance and risk management, published the first rules for hydrogen on ships in January 2018.
Leaders in Marine Propulsion; ABB, Ballard, and Kawasaki have developed advanced H²/Fuel Cell marine systems
DELOITTE RESEARCH has established that:
Fuel cells were the best choice, at approximately one-fifth the mass of lithium-ion batteries and about 20 percent smaller in terms of volume.
Total Cost of Ownership (“TCO”) analysis; concluded that within 10 years it will become cheaper to run a fuel cell electric vehicle (FCEV) than a battery electric vehicle (BEV) or an internal combustion engine vehicle (ICEV) for commercial vehicle applications.
There is a clear need and imminent requirements for reducing greenhouse gas emissions from ships and port operations. Fuel cell systems using renewable hydrogen are the most viable and scalable true zero emission solution for marine vessels. Furthermore, fuel cell systems offer the ship builder and operators the advantages of high efficiency, modular design for redundant and dispatchable power, DC power output, long lifetime, and rapid refueling.
Fuel cell technology: Net Zero does not equal ZERO
For marine vessels, fuel cells are the only viable, true zero-emission option. Just like batteries, fuel cells produce electricity with high efficiency through an electrochemical process. The difference is, with a fuel cell, energy is stored separately in the form of hydrogen fuel. As long as fuel is available, the fuel cell power systems will produce electricity as a generator. The only emissions from a fuel cell are water vapor and heat.
Hydrogen fuel can be produced from renewable sources, including:
Making the transition to a new energy source is a major undertaking. In the case of fuel cells for marine vessels, the hurdles are in the refueling infrastructure, and hydrogen availability in ports
Before operators can power their vessels using fuel cells, hydrogen supply and fueling infrastructure need to be further developed.
