There are three "clean coal" power plants in development with plans to produce ammonia as a byproduct.
If they get built, these projects will bring to market roughly 1.25 million metric tons of urea and 460,000 metric tons of UAN per year.
Unfortunately, the "clean coal" power industry appears to be in a bit of a pickle.

OWNER: Hydrogen Energy California (HECA), SCS Energy
PROJECT: Greenfield power plant, fertilizer byproduct
SUMMARY STATUS: On hold, indefinitely
Despite years of development, this "clean coal" project never came together. The local oil field backed out, leaving HECA in an existential crisis with no way to sell or sequester its CO2 and, in March 2016, the project put itself on indefinite hold, by withdrawing its application to the CEC.
