H2O2 is stable if stored correctly - it's been used as a storable rocket fuel oxidiser for instance. However, it can be broken down by an inorganic catalyst.... Perhaps we could inject, say, a palladium slurry instead of catalase?
But it's all just more and more plumbing!
Catalase is a much more efficient catalyst for breaking down H2O2 (hence it's name) so it would be fun to see how Catalase, Bugbuster and TwistDX co-exist! Or Palladium, come to that.
does hydrogen peroxide have a relatively short hald life? could we take advantage of that? or will the cold prevent in breaking down by itself?
