1. A method for reforming ammonia, comprising:
a. directing ammonia to a reformer at an ammonia flow rate to produce a reformate stream comprising hydrogen and nitrogen;
b. combusting a first portion of the reformate stream with oxygen to heat the reformer;
c. processing a second portion of the reformate stream in a hydrogen processing module; and
d. performing two or more of the following steps in response to a stimulus that occurs:
i. changing the ammonia flow rate;
ii. changing a percentage of the reformate stream that is the first portion of the reformate stream;
iii. changing a percentage of the reformate stream that is the second portion of the reformate stream; or
iv. changing a percentage of the reformate stream that is vented or flared.
 
31. A method for reforming ammonia, comprising:
a. directing ammonia to a reformer at an ammonia flow rate to produce a reformate stream comprising hydrogen and nitrogen;
b. combusting a first portion of the reformate stream with oxygen in a combustion heater to heat the reformer;
c. processing a second portion of the reformate stream in a hydrogen processing module; and
d. performing one or more of the following steps in response to a stimulus that occurs:
i. changing the ammonia flow rate;
ii. changing a percentage of the reformate stream that is the first portion of the reformate stream;
iii. changing a percentage of the reformate stream that is the second portion of the reformate stream; or
iv. changing a percentage of the reformate stream that is vented or flared, wherein at least part of the first portion of the reformate stream is directed from the reformer to the combustion heater without being directed to the hydrogen processing module.
