Where is that written? All of the action bar actions that use energy say that you use energy from the ship's card, but there isn't any rule saying that you can't use energy from one upgrade card for another unless also specfically stated. For example:

Shield Projector says that you may spend 3 energy, but it doesn't specify that it has to be from that card (because there isn't an energy limit on it so it has to be from another source) or the ship's pilot card. And since there is no written rule saying that you cannot use energy from another card unless stated on that card (like a weapon since all secondary weapons can only use energy from their upgrade card as stated on the card), there shouldn't be any reason why you can't use 3 energy from Ionization Reactor to activate Shield Projector.
