Yes, hydrogen, the smaller possible molecule, and carbon, which is smaller and lighter then oxygen
Hydrocsrbon chains are the most efficient way to store carbon, aside from something like graphite.
Who cares what it becomes when you burn it? CO2 is obviously not the optimal carbon sink, even before you start considering things like long term stability

Volumetric efficiency is not the relevant metric. Energy efficiency is much more important. The process you describe requires far greater energy input to complete the sequestration.
Furthermore, the physical properties are a problem. Biomass appropriate to this process is conveyed as a flammable, pelletized solid; CO2 is an inert fluid. One of these can be pumped via pipeline into empty subterranean reservoirs; the other cannot.
