    Agree , rather annoying they don't mention the water that must be required. However they do say they use CO2 dissolved in water so by implication that is the source of hydrogen. Presumably also, they generate free oxygen, but this is not mentioned either!

    2CO2 + 3 H2O + Energy ------- HH3-CH2-OH + 3O2 that is what you are saying
    I wonder if they used carbonic acid on some Copper catalyst

    They mention possible use as energy storage for when there's excess electricity supply, but I'm guessing the efficiency of the conversion process to ethanol and back would be pretty low indeed.
