Slush Hydrogen?

[More Boosters]

I came across slush hydrogen on Wikipedia but the page is hardly descriptive. Can anyone here share how it would actually work out as a rocket fuel? Googling "slush hydrogen as a rocket fuel" gives the same Wikipedia page as the first result so I'm not sure if it isn't something someone pulled out of their hat.

It said pretty clearly that it's basically hudrogen being stored at the triple point. Look up what that is. If you're too lazy, it's the point on a temp/pressure graph where a substance is at all three prime phases of matter.

Yes, I noticed that and I'm familiar with phase diagrams. I should have been more descriptive, I don't doubt the existence of the triple point (wut?), I simply never came across the notion of using it as rocket fuel before.

Bill Phil, your comment can easily be misconstrued as dismissive, please cake more care in how you present your responses, thanks.

It was used in some theoretical designs in the late 80s-90s SSTO craze, but AFAIK it's never been used in an actual engine, even on a test stand.

That wasn't the intent.

To be honest, quite a lot of what anyone says can be( and is) interpreted as dismissive.

But you can make sure it feels friendlier. By including emoticons and avoiding certain highly efficient but "cold" sentence strutures, you can usually disarm your main argument from its aggressiveness. Like, doesn't this whole post just feel so much nicer all of a sudden when you see this?

We're straying off topic. And the answer is no. It feels too childish.

I'm also not having a good day today.

Can we talk about slush hydrogen please?

Why exactly did they give up on it? Too hard to keep the thing at those conditions?

I believe that the triple point of hydrogen is difficult to achieve. We haven't even been able to store hydrogen as a solid.
