No. Hydration is the adding of water, hydrogenation is the addition of hydrogen.


Hydration example:
Some salts can have water molecules embedded in their crystal structure. Copper sulfate #CuSO_4# is white in its non-hydrated (anhydrous) form. If water or water vapour is added it turns into the hydrated form #CuSO_4*5H_2O# in which for every coppersulfate 5 water molecules are bound into the crystal grid.

Hydrogenation example:
In the preparation of margarine, oils may be hardened to fats by turning double carbon-carbon bonds into single. This is done by the addition of hydrogen (only one double bond is shown):
#-CH=CH- +H_2->-CH_2-CH_2-#

Of course there are many more examples of both.
