I called Hertz Dublin. Very helpful information which contradicts their website FAQ's which seems to generic.
I can use a Visa Debit Card or a Credit Card in the drivers name when I collect the car. Not sure if this applies to all Hertz outlets or just to Dublin.
Otherwise I think the cheapest option, barring getting a credit card in my own name, would be to name my wife as a driver on the booking and use her credit card.

Personal experience in Ireland (and generally with car hires, but not with Hertz Ireland) says: the credit card must be in the name of the driver and not be a prepaid one.
There's three options to possibly get around that:
Effectively there's no guarantee that either of those will be accepted by the company - some pleading and asking nicely may go a long way and especially if you take out the full additional insurance companies usually are quite happy to give you the car without a credit card.
