Fixing to pre-cast concrete

[Mairzydotes]

We are moving soon to a house which has a pre-cast comcrete garage.
We are going to need to use the garage walls as part of the storage, and as a non-DIYer it seems to me that the easiest option would be to fix strong wooden battens to the inside walls, and fix other necessary hooks etc to the battens.
But what is the best way to attach the battens themselves to the walls?
All ideas will be welcomed.
Also we will be keeping a fridge, freezer and wine store in there, so ideas for security are very necessary.
Many thanks.
