Chapter 200 doesn't go into much detail but chapter 7 (for metals) explains how the exchange will facilitate an independent middleman to store until arrangements are made and they will bill you for that service.

I have not been involved in chapter 200 operations but I've heard socially this occasionally happens relating to substandard product. "We agreed on light sweet crude in the contract but you tried to deliver sour tar". The exchange knows its all going to get dragged into court eventually, so they try to be fair and transparent and well documented. There are plenty of people renting tank space as a normal business operation.

I don't think you're going to get Force Majeure protection. That's for something neutral to all parties like a hurricane, not one side of the contract didn't feel like closing out and doesn't have tank space lined up.

My understanding is you still take delivery. It might be in the form of a fleet of tankers or barges arriving at your office. But, you will take delivery, whether you like it or not. Any responsible trading firm that deals in futures should have mechanisms in place to deal with physical delivery.
