How far can a car go on 1 kg of hydrogen?
One kg of hydrogen contains about the same energy as a gallon of gasoline. Today a fuel-cell electric vehicle with 1 kg of hydrogen can drive approximately 60 miles, compared to conventional vehicles, which get about 25 miles on a gallon of gasoline. Under “normal” pressure and temperature conditions, 1 kg of hydrogen occupies about 11,000 liters. Even if it contains, per kg, 4 times more energy than gasoline, the difference in volume is gigantic.A hydrogen car consumes an average of 0. So, for every 100 km driven, it uses less than 1 kg of hydrogen.There are two publicly accessible hydrogen refuelling stations in London. They are at the Centre for Engineering and Manufacturing Excellence (CEME) Campus, Marsh Way in Rainham, and the National Physical Laboratory, Essen Way in Teddington. Both stations offer refuelling for hydrogen fuel cell cars.The infrastructure for refuelling hydrogen cars is also severely lacking compared to electric charging stations. This limited availability makes it inconvenient and impractical for consumers to adopt hydrogen vehicles on a wide scale.
Is hydrogen cheaper than gasoline?
While hydrogen fuel cell vehicles offer impressive efficiency and zero emissions, their per-mile fueling costs in 2025 remain three to four-and-a-half times higher than those of both gasoline and hybrid vehicles. 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.Hydrogen fuel cell vehicles do not require traditional gasoline; instead, they use hydrogen as fuel. Their working principle is to directly convert the chemical energy of hydrogen and oxygen into electrical energy through fuel cells, which drives the electric motor to propel the vehicle.Tesla’s Unexpected Move to Hydrogen Despite this, Tesla now plans to transition to hydrogen power by 2026. Musk’s pivot to hydrogen is seen as a strategic move to stay ahead in the rapidly evolving automotive industry.It seems that battery electric vehicles currently have the edge over hydrogen fuel cell vehicles, although much of the reason for this is the fact that hydrogen is not as developed as a technology. However, given time and further development could see hydrogen catch up even as electric vehicles continue to advance.Elon Musk Said Hydrogen Fuel Cell Vehicles ‘Extremely Silly’: Some Experts Now Disagree.
Can a normal car engine run on hydrogen?
Yes. Hydrogen internal combustion engines (hydrogen ICE) work similarly to diesel engines. Hydrogen is burned in the same way a traditional internal combustion engine burns gasoline or diesel. While hydrogen fuel cell vehicles offer impressive efficiency and zero emissions, their per-mile fueling costs in 2025 remain three to four-and-a-half times higher than those of both gasoline and hybrid vehicles.The interest in hydrogen as an alternative transportation fuel stems primarily from its potential to power fuel cells in zero-emission vehicles (vehicles with no emissions of air pollutants). A fuel cell may be two to three times more efficient than an internal combustion engine running on gasoline.While hydrogen can be used to generate zero-emissions electricity, as an energy carrier, it needs to be produced from a primary energy source – often renewable electricity (and in some cases from natural gas with carbon capture).Hydrogen vehicles and battery electric vehicles do not require oil changes because they do not have combustion engines. Both hybrids and gas-powered cars do require regular oil changes as part of their routine maintenance.
