    Is this same as scramjet technology, or is it a new technology?

    Hydrogen isn't natural in molecular form, so it needs to be generated. That requires energy, so unless they use something like nuclear power to generate the hydrogen, it will most certainly not be ecologically friendly. Also, hypersonic flight itself is extremely inefficient.

    Tree hugging hippie crap aside, hypersonic flight is very cool. Their website shows a hybrid jet/rocket engine: http://www.reactionengines.co.uk/sabre.html

    Unfortunately, though, what we have here is neither a real company nor a real project. It's just press for the purpose of generating revenue.
