What is the efficiency of a hydrogen engine?
Hydrogen fuel cells are also far less efficient than the lithium ion batteries found in EVs. HFC vehicles achieve efficiency of around 40-60% – higher than the 30-40% for ICE vehicles, but significantly lower than the near 80% for plug-in EVs. Hydrogen vehicles require less frequent service than internal combustion engine (ICE) cars. Like battery electric vehicles (BEVs), they eliminate oil changes, spark plugs, and exhaust system repairs. However, FCEVs still include mechanical components that need regular attention.No, it’s unlikely that hydrogen cars will replace electric vehicles (EVs). They offer fast refuelling and longer ranges, but EVs benefit from an extensive charging infrastructure and lower costs.In 2025, hydrogen retailed for $27. Hydrogen has been used commercially for over 80 years, so it is a well-developed technology.Our green hydrogen RRP is £6. Kg, so it costs just £47. Kg tank (in under 4 minutes) giving over 400 miles/640 Km range, this equals 11.
Can a jet engine run on hydrogen?
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. Hydrogen Factsheet – China. China is the largest producer and consumer of hydrogen in the world.Hydrogen is likely to be an important tool for replacing fossil fuels in hard-to-abate industry, many processes of which are difficult to be electrified.Electrolysis-based hydrogen capacity, in kilotonnes per year China is currently the world’s largest consumer and producer of hydrogen.Other applications, such as light duty vehicles and heating in buildings, are no longer part of the future hydrogen economy, primarily for economic and environmental reasons. Hydrogen is challenging to store, to transport in pipelines, and to use.
What fuel do hydrogen engines use?
Fuel cell cars are powered by compressed hydrogen gas that feeds into an onboard fuel cell stack that doesn’t burn the gas, but instead transforms the fuel’s chemical energy into electrical energy. This electricity then powers the car’s electric motors. A typical hydrogen fuel cell lasts around 5,000 to 10,000 hours in vehicles, equivalent to 150,000 to 300,000 miles of driving.The NamX hydrogen car can be refueled in just 5 seconds and can travel up to 1,500 kilometers (about 932 miles) on one tank. This makes it a great choice for long trips, with the benefits of quick refueling and a long driving range.Fueling is Easy and Fast Fuel cell electric cars typically go 300 miles or more on a full tank of hydrogen, with the ability to refuel in 3 to 5 minutes. Hydrogen fueling is no more complicated or time-consuming than filling a standard car with gas.Efficiency. While a hydrogen fuel cell vehicle is more efficient than a car with an internal combustion engine, it’s not as efficient as a battery electric vehicle. An electric car is very efficient, converting more of the energy it consumes into movement than a hydrogen car.
Will hydrogen engines overtake electric?
The future of sustainable transportation may not be an exclusive competition between hydrogen and electric vehicles. Instead, there is growing recognition that both technologies could coexist, offering consumers choices that align with their needs and preferences. They still have a battery of course, but it’s much smaller than an EV’s. The trouble is, a battery EV is more efficient than a hydrogen car. So, as a rule a battery-electric car needs less energy than a hydrogen vehicle to go the same distance. Using less energy to do the same job is more sustainable.David Cebon, a professor of mechanical engineering at the University of Cambridge, said: “If you use green hydrogen it takes about three times more electricity to make the hydrogen to power a car than it does just to charge a battery. That could improve slightly but not enough to challenge batteries.
