  "textContent": "A method of reducing the greenhouse gas impact of livestock farming includes feeding a fuel gas comprising one or more hydrocarbons to an anode of a solid oxide fuel cell stack, withdrawing air, that includes methane originating from livestock, from a livestock housing or enclosure and feeding the withdrawn air to a cathode of the solid oxide fuel cell stack. The oxygen in the air is allowed exothermically to react with the one or more hydrocarbons in the fuel gas to form at the anode a heated first exhaust stream comprising water and carbon dioxide and at the cathode a heated second exhaust stream comprising methane, thereby generating an electrical current from the solid oxide fuel cell stack through an external electrical circuit. At least the heated second exhaust stream is fed to a combustor and combusted, producing a heated tail gas stream.",
