The manufacturing process of both electric and hydrogen fuel cell vehicles does create more initial emissions, mainly due to the mining of battery components; then an internal combustion engine (ICE) vehicle though battery electric vehicles create less emissions through their life cycle compared to the...
Internal combustion engine vs. electric drive A clear difference between the two drive technologies is the overall efficiency from the fuel source to the vehicle wheels. The entire efficiency chain for locomotion is examined, from the extraction and provision of drive energy to its conversion into k...
In principle, hydrogen can be used to power combustion engines, electric motors and hydrogen-oxygen fuel cells. In a hydrogen combustion engine, hydrogen is used as a fuel that drives the engine running by means of a detonating gas process similar to gasoline-powered engines. Fuel cell vehicle...
Another advantage of hydrogen fuel cell buses is their high energy efficiency. The energy conversion efficiency of a hydrogen fuel cell is much higher than that of a traditional internal combustion engine, which means that hydrogen fuel cell buses require less fuel to travel the same distance. Hy...
The first vehicle systems employs a gaseous hydrogen-fueled internal combustion engine (ICE) and either a liquid or metal hydride energy storage system. The second vehicle system employs an electronically controlled electric motor powertrain and a battery energy storage system. Major tasks included in ...
There is a lot of hydrogen in methanol, methanol can be cracked into CO and H2 through high temperature catalytic reaction, and then mixed with diesel to form alcohol-hydrogen mixed fuel for injection into the engine. It can solve the storage problem of hydrogen. Therefore, methanol can be ...
source for aircraft propulsion. First via hydrogen combustion in a gas turbine, second, by using fuel cells to convert hydrogen into electricity in order to power a propeller engine. A hydrogen gas turbine can also be coupled with fuel cells instead of batteries in a hybrid-electric archit...
Industry experts believe that the total cost of ownership of BEVs and FCEVs could converge over the next decade and become competitive with internal-combustion-engine (ICE) vehicles 12 or 15 years from today. Based on their entire life cycles, FCEVs achieve very low CO2 emissions, i...
Hydrogen combustion engines work by burning hydrogen in a conventional internal combustion engine, changed to manage the high-speed combustion of hydrogen. They run on similar principles as diesel engines but require specific technologies, such as specialized fuel injectors and ignition systems. These he...
