Process to produce hydrogen and oxygen from underground systems

A method for producing hydrogen comprising:

• providing a well from a surface to an underground formation;
• locating at least one electrolyzer in the well;
• supplying the at least one electrolyzer with supply electricity;
• supplying the at least one electrolyzer with supply water;
• producing hydrogen gas at the electrolyzer;
• and
• collecting and transporting the produced hydrogen gas to the surface.

A method for producing hydrogen from a underground system comprising:

• providing a well from surface to the underground;
• locating at least one electrolyzer in the well at one or more depths;
• supplying water to the electrolyzer through a connection;
• supplying electrical current to the electrolyzer to generate oxygen and hydrogen;
• separating the generated oxygen and hydrogen to fill at least one hydrogen tubing string and at least one oxygen tubing string to a desired pressure;
• producing the gases from the tubing strings separately at the desired target pressure on surface;
• generating energy through at least one of:
• passing at least one of the high pressure oxygen and hydrogen through a turbine to generate rotational energy;
• passing at least one of the high pressure oxygen or hydrogen a turbine and electrical generator to generate electrical power;
• feeding the produced hydrogen to a combustion engine and combusting it for rotational energy;
• feeding the hydrogen to combustor for heat;
• and
• feeding the hydrogen to a fuel cell for the generation of electrical power;
• providing the produced water from the step of generating energy to feed the electrolyzer;
• passing the high pressure oxygen at a desired pressure to a storage vessel on the surface for storage or transport;
• and
• passing the high pressure hydrogen at a desired pressure to a storage vessel on the surface for storage or transport.
