Abstract

Proposed is a system for generation of blue hydrogen through natural gas reforming, carbon dioxide capture, carbon resource utilization, and reaction product storage. The system includes a natural gas storage container for storing liquefied natural gas including shale gas, a hydrocarbon reformer in which a gas mixture containing hydrogen and carbon dioxide is produced, a hydrogen filling station in which hydrogen is received and stored, a reactor in which carbon dioxide produced is received and reacted with a basic alkali mixed solution to capture carbon dioxide and in which a reaction product is collected and a carbon dioxide reaction product and a waste solution are separated from the reaction product, a carbon resource storage container storing the carbon dioxide product, and a hydrogen generator in which the carbon dioxide reaction product is used to product hydrogen, and the produced hydrogen is delivered to the hydrogen filling station.

Dependent claims

A system for generation of blue hydrogen through natural gas reforming, carbon dioxide capture, carbon resource utilization, and reaction product storage, the system comprising:

a natural gas storage container configured to store Liquefied Natural Gas (LNG) containing shale gas;
a hydrocarbon reformer configured to generate a gas mixture containing hydrogen and carbon dioxide by a reacting water supplied from outside and natural gas or shale gas supplied from the natural gas storage container to each other;
a hydrogen filling station configured to receive and store hydrogen generated from the hydrocarbon reformer;
a reactor configured to capture carbon dioxide by receiving carbon dioxide generated from the hydrocarbon reformer and reacting the carbon dioxide with a basic alkali mixed solution, the reactor being configured to collect a reaction product containing the captured carbon dioxide, and the reactor being configured to separate a carbon dioxide reaction product and a waste solution from the reaction product;
a carbon resource storage container configured to store the carbon dioxide reaction product separated from the reactor;
and
a hydrogen generator configured to generate hydrogen by using the carbon dioxide reaction product which is separated from the reactor and which is directly transferred to the hydrogen generator or by using the carbon dioxide reaction product transferred to the hydrogen generator via the carbon resource storage container, the hydrogen generator being configured to transfer the produced hydrogen to the hydrogen filling station.

A method for generation of blue hydrogen through natural gas reforming, carbon dioxide capture, carbon resource utilization, and reaction product storage, the method comprising:

a process A in which a natural gas storage container liquefies and stores a source gas containing shale gas;
a process B in which a hydrocarbon reformer reacts water input from outside with the source gas stored in the natural gas storage container so as to generate a gas mixture containing hydrogen and carbon dioxide and separates hydrogen in the gas mixture and then transfers hydrogen to a hydrogen filling station;
a process C in which a reactor captures carbon dioxide by reacting a basic alkali mixed solution with carbon dioxide generated from the hydrocarbon reformer in the process B and collects a reaction product containing the captured carbon dioxide;
a process D in which a hydrogen generator generates hydrogen by using the reaction product containing carbon dioxide captured by the reactor and transfers hydrogen to the hydrogen filling station;
and
a process E in which a carbon resource storage container stores the reaction product containing carbon dioxide captured by the reactor or supplies the reaction product to the hydrogen generator so as to generate hydrogen.
