Electric propulsion systems are not #energy limited. An arbitrarily large amount of energy can be delivered (from a #solar βοΈ or #nuclear β’οΈ power system) to a given mass of propellant so that the exhaust velocity (or specific impulse) can be much larger than that available from a #chemical propulsion system. Electric propulsion systems are termed " #power π limited" https://sci.esa.int/web/smart-1/-/34201-electric-spacecraft-propulsion?section=electric-versus-chemical-propulsion
