Gasoline vehiclesEconomic costsFuel costFuel cell systemsAir pollutionVarious alternative fuels and vehicles have been proposed to address transportation related environmental and energy issues such as air pollution, climate change and energy security. Hydrogen fuel cell vehicles (FCVs) are widely seen as...
Compared to gasoline and diesel fuel which are heavy and can be collected near the ground, hydrogen does not stay near the ground due to its density, and it dissipates in the air. Therefore in the case of a car accident, the safety of a hydrogen-fuel car is higher than petrol [28]....
A hydrogen fuel cell bus has three main components: the fuel cell stack, the electric motor, and the hydrogen storage tanks. The fuel cell stack is made up of individual fuel cells that combine hydrogen and oxygen to produce electricity, heat, and water as byproducts. The electric motor is...
Is hydrogen propulsion the future? How does a fuel cell work? Are there any risks? In this article, a hydrogen propulsion expert from BMW will answer these questions and more.
A major hurdle to hydrogen as a fuel is the public perception that it's unsafe. While automakers assure the public that hydrogen is as safe as gasoline, they aren't always convincing. For example, during his test of the BMW Hydrogen 7, New York Times auto critic Lawrence Ulrich was ...
Hydrogen fuel cells are an efficient power source for trucks, construction equipment buses and industrial or marine applications, as they benefit from a high energy-to-weight ratio. Unlike batteries, which add weight and require longer recharge times, fuel cells can power heavy loads over longer ...
36、tempting to develop technology that can rival the performance and cost of gasoline fuel storage systemsHow will the hydrogen be stored?Using current storage technology, in order to place a sufficient amount of hydrogen onboard a vehicle to provide 300-mile driving range the tank would be lar...
Step-by-Step Text Solution:1. High Energy Efficiency: Hydrogen as a fuel has a very high energy efficiency, typically greater than 80%. In comparison, gasoline and coal have energy efficiencies that are equal t
1 gal of gasoline has about the same amount of energy as 1 kg of hydrogen. Most fuel cell electric cars carry about 5 kg to 6 kg of hydrogen but go twice the distance of a modern internal combustion engine car with equivalent gas in the tank, which works out to a gasoline-per-gallon...
Lastly, it was found that the WTW assessment was necessary to adequately evaluate fuel/vehicle systems [14]. Table 4. Supply pathways analyzed by Huang and Zhang 2006 [14]. PathwayFeedstockFuel Reference Petroleum Gasoline 1 Natural gas GH2 central plant 2 Natural gas GH2 refueling station 3 ...
