A reformer assembly includes a vortex tube receiving heated fuel mixed with steam. A catalyst coats the inner wall of the main tube of the vortex tube and a hydrogen-permeable tube is positioned in the middle of the main tube coaxially with the main tube. With this structure the vortex tube outputs primarily Hydrogen from one end and Carbon-based constituents from the other end. In some embodiments a second vortex tube receives the Carbon output of the first vortex tube to establish a water gas shift reactor, producing Hydrogen from the Carbon output of the first vortex tube.

A turbo-expanding cracking assembly includes a plurality of stages each including a rotating blade coupled to an output shaft and a fixed stator, at least one heat exchanger configured to transfer heat to an ammonia containing fuel flow, and a catalyst that is configured to decompose an ammonia containing fuel flow into a flow containing hydrogen (H2).

Systems and methods for generating power using hydrogen fuel, such as derived from natural gas, are provided. Feed materials are introduced into a compact hydrogen generator to produce carbon dioxide, hydrogen gas and steam. Sorbent material within the compact hydrogen generator acts to absorb carbon dioxide, forming a used sorbent. Hydrogen gas and steam are separated from the used sorbent and passed to a power generator such as a hydrogen turbine to produce power. The used sorbent is introduced into a calciner and heated to desorb carbon dioxide and form a regenerated sorbent which can be recycled to the compact hydrogen generator.

The invention discloses a new type of integrated cycle to compete with the standard gas-steam combined cycle in terms of full load/part load efficiency besides ramp rate, startup time and other off design performance. The topping cycle is intercooled recuperative gas turbine (ICR GT) with multiple intercoolers. The bottoming compound cycles consists of supercritical refrigerant Rankine cycle (RRC) and vapor compression refrigeration cycle (VCRC).
