The main technical difficulty in dealing with fusion reactions is that the amount of energy needed to overcome the electrical repulsion of the reactants is extremely high. This is because the positively charged nuclei of the reactants repel each other due to their like charges, and a high amount of energy is needed to bring them close enough together for the strong nuclear force to take over and bind them together.
