New Yanmar Toyota fuel cell system for boats - Plugboats (2024)

FAQs

How soon will hydrogen cars be available? ›

Essentially, they're near impossible for the public to get a hold of, however there are plans for the hydrogen car market to ramp up over the next few years. The BMW iX5 Hydrogen is another example that isn't too far away, planning public availability by 2030.

The Wärtsilä 31 engine, which has been recognised by Guinness World Records as being the world's most efficient 4-stroke diesel engine, has been... The best-in-class fuel efficiency of the Wärtsilä 31 engine means also that the exhaust emissions are correspondingly minimised.

In the USA, hydrogen costs around US$16 per kilogram. Currently, renewable hydrogen produced via electrolysis costs between US$3 – US$6/kg, though analysts expect this figure to drop significantly over the next decade.

There are two hydrogen fuel cell electric vehicles (FCEV) on sale in the U.S. at the moment, the 2024 Hyundai Nexo compact crossover and the Toyota Mirai sedan.

Hydrogen fuel is much more efficient than gasoline, but it's also four times more expensive, roughly equivalent to about $16 a gallon.

In 2025, levelized costs of hydrogen are expected to amount to 6.90 U.S. dollars per kilogram. The U.S. hydrogen market is projected to generate up to 140 billion U.S. dollars and offer 700,000 additional jobs by 2030.

Used Yanmar diesel engines for sale are cheaper and cost between 500 to 5000 USD. New Yanmar diesel engine models cost up to 180,000 USD, depending on the size and application.

Generally, once the boat is fully on plane, the most efficient cruise is likely to come in the 3000 to 5000 rpm range, with steadily deteriorating efficiency after it peaks. In reality, few people cruise their boat at its most efficient speed most of the time.

The fuel cell stacks are designed to last the lifetime of the vehicle, about 150,000–200,000 miles. At the end of its lifespan, the fuel cell will be disassembled and the materials recycled, similar to what happens with vehicle components today.

Is hydrogen fuel cell cheaper than gas? ›

Fueling Costs

While the current price of hydrogen is higher than gasoline, fuel cells are approximately 2.5 times more efficient than gasoline engines. An added bonus is that most fuel cell car manufacturers include three years' worth of free fuel with a vehicle.

As a reminder, the average for green hydrogen deals in Europe from 2024 was €9.49 per kilogram or $10.30. No one is thinking that actually low-carbon hydrogen is going to cost $1.50 per kilogram in 2024, yet it's in an official NREL report and is artificially deflating the price point.

Safety concerns over hydrogen flammability and electrical shock. Maintenance costs remain unclear. Potential for high costs to refuel when manufacturer incentives run out. The unknown future for these automobiles.

Unfortunately, a hydrogen fuel cell offers few advantages over a battery, with several deal-breaking disadvantages. The problems that show no sign of really being overcome include cost, lack of infrastructure and relative inefficiencies in delivering hydrogen to customers.

Will hydrogen cars ever replace traditional EVs? For now, it appears hydrogen cars have an uphill battle to catch traditional EVs. Even in California, the only state where they are seen on a widespread scale, there were "just under 12,000 fuel cell electric vehicles" in 2022, said Wired.

The two prime dangers from fuel cell and hydrogen-powered vehicles are the danger of electrical shock and the flammability of the fuel. Fuel cells power vehicles by electro-chemically combining hydrogen gas (H2) and oxygen (O2) from the surrounding air into water (H20) and electrical energy.
