Hydrogen may be promising by the fact that it only produces water vapor when consumed as fuel. It is also one of the most prevalent resources on our planet at the moment so their is no shortage of it for us to use. However there is only one problem with hydrogen though. With our current technology, it takes way more energy to make hydrogen then hydrogen will generate when used as fuel.

∙ 13y agoLiquid hydrogen contains a lot of energy in an extremely small space. A rocket needs to carry the weight of the fuel as well as the payload. As a result, the United States uses liquid Hydrogen for the first stage of its rockets.
Russia uses kerosene instead of liquid hydrogen because kerosene is a lot easier to handle and does not require expensive refrigeration equipment.

∙ 12y agoBecause it has low activation energy so doesn't take a lot of heat energy to start a reaction. Also, it is a liquid so is easier to burn as it has low boiling points.

Is hydrogen useful to fly?
Yes, that's what they filled the Hindenburg with but we all know how that turned out.
Shape of hydrogen?
Hydrogen is a gas and so has no shape.
What is the first maneuverable spacecraft?
The first maneuverable spacecraft is considered to be the Gemini Spacecraft. This was NASA's second human spacecraft, and its mission lasted from 1965 to 1966.
Is hydrogen gas an element or a compound?
hydrogen gas is H2 so it only contains hydrogen. therefore it is an element
Does sugar have more hydrogen than fat?
Fat is not a chemical compound, so it does not have a chemical equation, so it does not have a measured amount of hydrogen. (Sugar has 12 hydrogen atoms.)
Why is fuel cell so useful to spacecraft?
Without fuel, the spacecraft cannot launch.
Why is fuel so useful in spacecrafts?
Fuel is so useful to spacecrafts because without the fuel the spacecraft would not go.
What is a fuel cell and why is it useful in spacecraft?
it lifts up the spacecraft
Why is a fuel cell useful in spacecraft?
because hydrogen is in the fuel cell. hydrogen is useful in many things including spacecrafts. please do not use this for anything important because I'm not sure but i been reading this page about hydrogen and it is true. I know for sure that hydrogen is used for rocket fuel because it is on the sheet. By Georgina thank you 4 going on wikianswers.com
Why are fuel cells so useful in spacecrafts?
They supply power to the spacecraft during missions.
How are manned spacecraft useful?
Manned spacecraft are very useful because it is easier to see and do things first hand than relying on only readouts from machines and senors.
What a fuel cell is why is it useful in spacecraft?
a fuel cell is a cell that produces electricity they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells
Is their anything of value on Jupiter?
Yes, certainly. Jupiter is covered with hydrogen gas, the simplest element in the universe. It will be incredibly useful as spacecraft fuel in the coming centuries. EVERY kind of matter is valuable. It's all in how you use it.
Why is a fuel cell so useful in spacecraft?
they are used to provied power and water for the spacecraft so the space craft could'nt really survive with out fuel cells Because fuel cells do actually fart it's well documented. And they do a poo when they get tired! < SOOO TRUE!!
What is the most useful compound of hydrogen?
water
Why do modern spacecraft use helium instead of hydrogen?
Helium is much safer, so it is often used in balloons and blimps, not spacecraft.Hydrogen is still used as a fuel. Helium will not burn.
What is a fuel cell and why is it so useful in spacecraft?
because it is to do with other planets but mostly mars and galexy if we had the tehcnical difficultys in the balance of time, timeloards from doctor who would come back to life if we belived.
