I need to use a device to store charges generated from ocean energy? Can I use CCD and a capacitor?

First you need to learn the basic principles of your business, starting with what the words mean. As far as I know, a CCD is a component in a digital camera, and that does not apply to your project. Energy is not a physical unit, it is a philosophical concept. Here is a free course in basic electronics:

Maybe I don't understand your goal, but I think what you want is a lead-acid battery.
