But The Edge told the Press Association that a venue in Northern Ireland may come to the rescue.
"This show is designed for a type of venue and unfortunately there isn't one, certainly in the south, I think there might be one in the Belfast area so we're looking at that as well.
"But you can't invent a venue. It's either there or it isn't. So we're doing a lot of head scratching right now to see if we can figure out something," he said.
Pressed on whether U2 may be coming to Belfast, The Edge said: "I wouldn't rule it out."
There has been much speculation about U2 adding dates in Ireland to the tour, and The Edge said: "We are certainly working very hard on it and we can't announce anything right now but it would be a huge disappointment to us if we weren't able to play in Ireland and so every effort is going in to make that possible."
The band has just kicked off the European leg of their world tour and will be playing a string of dates at The O2 in London and dates in Glasgow, before finishing up in Paris in November.
Speaking about their Irish fans, The Edge said: "It's a home crowd and they know us better than anyone else. They know all the references better than anyone else.
"I would say it's the most appreciative and in some ways also the toughest crowd, because they know what to expect. They've high expectations."
