Abstract
The present invention relates to net-zero hydrogen plants and methods of operating said plants having a lower cost and much larger scale compared to electrolysis driven plants utilized to produce green hydrogen.
Claims4
A method for producing a low carbon intensity hydrogen in a net-zero hydrogen product plant, comprising:
- processing a hydrocarbon feedstock in a reforming unit to obtain a first syngas stream;
- processing a biomass in a gasifier unit to obtain a second syngas stream;
- capturing and sequestering the carbon dioxide from the first and second syngas stream;
- and
- combining the first and second syngas stream at a ratio of dry syngas at a ratio of first syngas stream to that of the second syngas stream of 3 to 6.

A method for producing a low carbon intensity hydrogen in a net-zero hydrogen product plant, comprising:
- processing a hydrocarbon feedstock in a hydrocarbon reformer train to obtain a first syngas stream;
- processing a biomass feedstock in a biomass train to obtain a second syngas stream;
- capturing and sequestering the carbon dioxide from the first and second syngas streams;
- and
- further processing the first and second syngas streams to obtain a combined hydrogen stream having a carbon intensity of 0.5 kgCO2/kgH2.
2 more elements
A net-zero hydrogen plant, wherein the carbon intensity of the hydrogen produced is 0.5 kgCO2/kgH2 or less, comprising:
- a first reforming train to process the hydrocarbon feedstock and produce a first syngas stream;
- a second reforming train to process a biomass based feedstock and produce a second Syngas stream;
- and
- combining the streams and further processing the resulting syngas stream in a shift reactor, carbon capture unit and a pressure swing adsorption unit to obtain a hydrogen having a carbon intensity of 0.5 kgCO2/kgH2 or less.
