Abstract

A method for producing ultra-low carbon hydrogen, including producing a flue gas stream, a raw syngas stream, and a high-pressure steam stream in a syngas generator, introducing the flue gas stream into a point-source carbon capture unit, thereby producing a clean flue gas stream and a first carbon dioxide stream, introducing an ambient air stream into a direct air carbon capture unit, thereby producing a clean air stream and a second carbon dioxide stream, and combining the first carbon dioxide stream and the second carbon dioxide stream and storing the combined carbon dioxide stream. The method may also include introducing the high-pressure steam stream into a steam turbine generator, thereby producing electrical power. The method may also include utilizing at least a portion of the electrical power in the direct air carbon capture unit.
