HYDROGEN PRODUCTION FROM GEOTHERMAL RESOURCES USING CLOSED-LOOP SYSTEMS

Described are methods and systems for producing hydrogen using closed-loop geothermal technology from geothermal, oil and gas or other resources. Various configurations and types of closed-loop systems are described which enable the capture, transfer and use of heat from the resource and from chemical reactions from the processes and methods employed and to also create high down bore pressure, in each case to enhance the technical and commercial efficiency of various hydrogen production methods. As hydrogen is created at high pressures and purities which are necessary for delivery and commercial use of hydrogen, the need for additional compression and purification activities is minimized. Various of the methods and systems described can make hydrogen produced from fossil fuel inputs less carbon intensive and make renewable fuel inputs produce hydrogen entirely without carbon outputs, thereby contributing substantially to the reduction of greenhouse gasses.
