Reactor vessels with pressure and heat transfer features for producing hydrogen-based fuels and structural elements, and associated systems and methods. A representative reactor system in accordance with a particular embodiment includes a first reaction zone and a heat path positioned to direct heat into the first reaction zone, a reactant source coupled to the first reaction zone, and a first actuator coupled to cyclically pressurize the first reaction zone. The system can further include a second reaction zone in fluid communication with the first, a valve coupled between the first and second reaction zones to control a flow rate therebetween, and a second actuator coupled in fluid communication with the second reaction zone to cyclically pressurize the second reaction zone. A first heat exchanger is positioned to direct heat from a first product leaving the first reaction zone to a reactant entering the first reaction zone, and a second heat exchanger is positioned to direct heat from a second product leaving the second reaction zone to the reactant entering the first reaction zone. A controller is coupled to the first and second actuators and is programmed with instructions that, when executed, control the first and second actuators in a coordinated manner based at least in part on a flow rate of the second product from the second reaction zone.
