Kodak, I am very sure United Nuclear has based their calculatins on the use of pure hdrogen in the storage tank. They would not take the risk of recommending storing hydrogen and oxygen in the storage tank. That would be an extreme liability issue. If there was ever a slight backfire in the engine, it could potentially flash all the way back into the storage tanks because you would have everything there you need to complete combustion. This has the potential for extreme destruction and death.
You don't have to believe me. Contact United Nuclear and tell them what you are proposing. They are the experts, let them guide you.
I have no desire to spend time solving the problem you presented. Since United Nuclear has already solved it, it would be a great waste of my time. I would rather use it for something useful. I consider trying to save your life useful even if you choose to ignore the advice.
