Er, thanks, although I have to say I got a bit lost there. When you say 'proposals to just essentially burn the hydrogen', do you mean 'burn the oxygen' in the CO2? Even if it only used half the energy, it would mean you're left with carbon (I assume), and not the 'dangerous' CO2. The other part is, isn't carbon useful? Carbon nanotubes? Graphene? Why does it have to be buried?
