1. A system for wireless transmission of power in deep subsurface monitoring, the system comprising:
a casing including a conductive material;
an oscillating current source configured to energize the casing; and
at least one wireless telemetry module disposed on the casing, the wireless telemetry module including:
a shell;
a toroidal antenna disposed within the shell, the toroidal antenna configured to collect electrical energy from an energized casing, wherein the toroidal antenna includes a winding of loops of conductive wire around a ring of material with a high value of magnetic permeability, wherein the material includes mu-metal;
a battery pack disposed within the shell, configured to store the collected electrical energy;
a CO2 sensor configured to generate a signal indicative of a CO2 concentration; and
an amplifier configured to process the signal from the CO2 sensor; and
a voltmeter, including a first terminal and a second terminal, wherein the first terminal is connected to the casing and the second terminal is connected to the toroidal antenna,
wherein the at least one wireless telemetry module is located in a CO2 reservoir.
