Mobile transport platforms for producing hydrogen and structural materials, and associated systems and methods are disclosed. A system in accordance with a particular embodiment includes a mobile transport platform and a chemical reactor carried by the mobile transport platform. The chemical reactor is configured to dissociate a donor into first and second constituents in a non-combustion reaction. The reactor has a donor entrance port, a first constituent exit port, and a second constituent exit port. A donor supply is carried by the mobile transport platform and is coupled to the donor entrance port to deliver the donor to the reactor. A first collector is coupled to the first constituent exit port to receive the first constituent from the reactor. A second collector is coupled to the second constituent exit port to receive the second constituent.
