1. A system, comprising:
a reactor comprising a first portion and a second portion, the first and second portions separated by a hydrogen-permeable membrane;
a first ammonia source configured to be in fluid communication with the first portion of the reactor;
a second ammonia source configured to be in fluid communication with the second portion of reactor; and
a heat source,
wherein the system is configured so that, during use of the system:
the first ammonia source supplies ammonia to the first portion of the reactor;
the heat source heats the ammonia in the first portion of the reactor so that the ammonia in the first portion of the reactor is converted to hydrogen and nitrogen;
the hydrogen passes through the hydrogen-permeable membrane and enters the second portion of the reactor; and
the second ammonia source supplies ammonia to the second portion of the reactor in the form of a gas stream that removes the hydrogen from the second portion of the reactor.
