H1Z1 won't be concerned with money, seeing as how they'll be busy trying to fortify themselves against hordes of shambling zombies. Sony Online Entertainment, however, does indeed want to make money off of the game. President John Smedley took to Reddit to share the details of the team's first monetization meeting, and while it's not a decisive list of how the game will make money, it serves as a preview.
The early list contains character slots, wearable items, crates with random selections of wearable items, and emotes. The team also intends to allow players to loot wearables from other players, but looted cash items will degrade over time rather than being perpetual acquisitions. Smedley makes it clear that resources like food, water, and ammunition will not be sold, nor will any boosts to those resources, since acquiring these assets makes up the core of the gameplay. Take a look at the post for the details and the community response.
