A friend tipped me off on Apple's fuel cell projects on Saturday, but I've been busy and couldn't get to the post until today.
There is news on the fuel cells following Apple's news on solar powering 20MW.
ArsTechnica has a post pointing to other information.
Apple building fuel cells to help power N. Carolina data center
Apple plans to build a massive fuel cell facility in North Carolina to accompany the data center that powers iCloud. The company revealed its plans as part of a filing with the North Carolina Utilities Commission and was first reported by the Greensboro News & Observer, which noted over the weekend that the project will be the "national's largest such project not built by an electric utility company."
If you look at the official filing you can see a bit more details.
GigaOm's Katie Fehrenbacher speculates that the fuel cells are Bloom Energy.
