A system for heating water for an oil and gas well treatment system utilizing raw natural gas from an oil and gas well. The system includes a separation assembly to remove liquids from the raw natural gas, wherein at least a portion of heated water from a frac water heater is passed through the separation assembly to prevent freezing therein.

Embodiments of a system for on-site conversion of carbon dioxide from vehicle exhaust to liquid fuels and fuel additives comprise a carbon dioxide collection system, an external power source, an electrolyzer, and a carbon dioxide conversion system. The carbon dioxide collection system interfaces with a mobile carbon dioxide capture system onboard a vehicle to transfer CO.sub.2 captured from vehicle exhaust to a vessel in the carbon dioxide collection system. The external power source provides the energy required for operation of the carbon dioxide conversion system and the electrolyzer. The electrolyzer separates a water feed into hydrogen and oxygen to generate a hydrogen feed and an oxygen feed. The carbon dioxide conversion system converts the CO.sub.2 collected from the exhaust of the vehicles and delivered to the carbon dioxide collection system and the hydrogen feed from the electrolyzer into useful liquid fuels and fuel additives through electrochemical reduction.
