Well... what about the energy used in splitting water in the first place? This is I think the biggest problem - splitting water to then have it re-created doesn't create a surplus of energy. Plus, you have to compress the H2 gas to be able to store and transport it - which uses more energy.
Of course you could create this energy with renewables - but then why not use them straight away in the first place?
