Electrolysis is a name of a process that does this. I'm not sure if it's the only one. I know there's photochemistry aswell.

Breaking molecular bonds always takes energy. So you'll need some sort of input. (Light, electricity, heat)

Breaking molecular bonds always requires initial starting energy but once started all exergonic reactions actually release energy as bonds are broken.
