Expert Answer:

Oxidation reactions are exothermic(or exergonic) and release energy.
Burning of hydrogen fuel releases heat to the surrounding and is an exothermic reaction.
Reduction reactions are endothermic(endergonic) and harness energy.
Dissociation of water into hydrogen and oxygen through electrolysis is an endothermic reaction.
