water ice could be melted and purified for drinking.It could also be broken down into its component parts—oxygen and hydrogen.Oxygen could be used to breathe. And hydrogen could be turned into fuel, rocket fuel.So, water ice could enable the creation of a self-sustaining Moon base someday...
It's a car powered by hydrogen (yes, it's that simple, folks). Hydrogen has been spoken about as The Next Big Thing every year for too many decades now. And yet it still hasn’t happened, but the fact it is the lightest and most explosive gas in the world might help explain wh...
Pure water (H2O) emerges as the sole emission, signaling a notable shift away from the carbon emissions typically linked with traditional power generation methods reliant on combustion. This elegant electrochemical dance between hydrogen and oxygen not only yields electrical power but does so with rema...

What group does hydrogen belong to? Where do hydrogen ions come from? What is the difference between an atom and an ion? What is the charge of an oxygen ion? What is the charge of a proton? What is the ion symbol for an atom with 20 protons and 18 electrons?
Why is hydrogen important as a future clean energy source? A fuel is a chemical that can be ‘burnt’ to provide useful energy. Burning normally means that chemical bonds between the elements in the fuel are broken and the elements chemically combine with oxygen (often from the air). ...

Unlike NASA's SLS, which flies on super-chilled liquid hydrogen and oxygen, this beast is fueled with 10 million pounds of liquid methane and oxygen. The new fuel can be stored at more manageable temperatures than liquid hydrogen, meaning it doesn't need as much insulation and is less ...
