Methane mitigation system with use of waste heat for power generation

A method of mitigating methane, the method comprising:

• producing, by an exhaust source, an exhaust gas containing methane;
• performing, by a burner arranged downstream from the exhaust source, a combustion with a natural gas and oxygen to generate heat that heats the exhaust gas to produce a hot exhaust gas that is hotter than the exhaust gas;
• heating an oxidation catalyst, arranged downstream from the burner, with the hot exhaust gas;
• converting, by the oxidation catalyst, at least a portion of the methane in the hot exhaust gas to carbon dioxide (CO2) to produce a methane-depleted exhaust gas, wherein heating the oxidation catalyst increases an amount of methane converted by the oxidation catalyst into the CO2;
• providing heat to an electrical power generator, arranged downstream from the oxidation catalyst, with the methane-depleted exhaust gas;
• generating, by the electrical power generator, electric power using heat from the methane-depleted exhaust gas, wherein heating the electrical power generator with the methane-depleted exhaust gas increases a temperature of the electrical power generator to a target temperature range in order to increase a power generation efficiency of the electrical power generator;
• and
• outputting, by the electrical power generator, the electric power to an electrical load.
