A method of isolating hydrogen from water in a reactor includes charging a centrifuge with water via an inlet including an inlet valve. The centrifugal centrifuge is situated in a protective chamber. The method also includes heating the centrifuge such that at least some of the water splits into hydrogen and oxygen, rotating the centrifuge within the protective chamber such that the hydrogen and oxygen separate within the centrifuge according to their molecular mass, and drawing off at least some of the hydrogen from the centrifuge via an outlet including an outlet valve.

A hydrogen isolation system includes a protective chamber and a centrifuge situated in the protective chamber. The centrifuge is configured to receive water and configured to rotate within the protective chamber such that constituents inside the centrifuge separate according to their molecular weights. The hydrogen isolation system also includes an energy source configured to provide heat to the centrifuge such that at least some of the water splits into hydrogen and oxygen.

A water splitting includes a centrifuge situated in the protective chamber and rotatable within the protective chamber such that constituents inside the centrifuge separate according to their molecular mass; an inlet fluidly connected to the centrifuge and configured to provide water to the centrifuge; and an outlet fluidly connected to the centrifuge and configured to remove hydrogen isolated from the water from the centrifuge. A method of isolating hydrogen from water in a reactor is also disclosed.

A reaction system includes a wellbore extending from a surface into a subterranean heat source. The reaction system further includes a reaction chamber configured to be maintained at a reaction temperature using heat from the subterranean heat source. The reaction system further includes one or more inlet conduits. The inlet conduits are configured to provide one or more feed streams to the reaction chamber. The reaction system also includes outlet conduits configured to allow flow of one or more product streams.

The present invention relates to a catalyst for the thermochemical generation of hydrogen from water and/or the thermochemical generation of carbon monoxide from carbon dioxide comprising a solid solution of cerium dioxide and uranium dioxide.

A reactor system including a plurality of catalytic modules connected end-to-end, forming a passage for reactants to pass through individually heated catalytic heating elements, thereby producing products. Each catalytic module has an insulating housing containing a catalytic heating element and configured to pass reactants over the catalytic heating element. A conductor in the module applies electricity to the catalytic heating element, which operates as a combined catalytic material and heating element.

A method for producing hydrogen by thermochemical splitting of water includes injecting one or more feed streams of water into a reaction chamber. The method further includes using a molten salt heated by a subterranean heat source to carry out the thermochemical splitting of water to form hydrogen and oxygen in the reaction chamber. The formed products are subsequently removed from the reaction chamber. Hydrogen formed in the reaction chamber may be used in a downstream process to generate hydrocarbons.

A system for co-generating ammonia and power is described. The system includes oxygen transport reactors having an ion transport membrane (ITM) that separates a feed side and a permeate side. The feed side includes a feed inlet and a feed outlet, and the permeate side includes a permeate inlet and a permeate outlet. A first feed inlet receives water vapor to be converted into hydrogen and first oxygen, and a second feed inlet receives air to be split into nitrogen and second oxygen. The ITM selectively allows permeation of the first oxygen and the second oxygen to respective permeate side to support oxy-combustion process. A first feed outlet discharges hydrogen and a second feed outlet discharges nitrogen, where the hydrogen and the nitrogen are combined in a catalytic converter to form ammonia. Combustion gases from the oxygen transport reactors are used to run a gas turbine to extract power.

Contemplated systems and methods for hydrogen production use a solar heliostat system as an energy source to produce hydrogen during daytime, and employ molten salt as an energy source to produce hydrogen during nighttime.
