Description

Title
Techniques To Synthesize Greenhouse Gases (Docket Number AM-004WO)
Technical Field
The present invention generally relates to the capture and conversion of greenhouse gas emissions.
Background Art
[0001] As the world closes in on decarbonizing our planet, some industries' path to net zero is undetermined. Some suggest that combustible fuels that produce no greenhouse gases (such as hydrogen) can fulfill that need. The drawback to this strategy is that there is an energy penalty for transporting the fuel to the location where it gets used as well as the extra logistical challenges of storing different types of fuels. By capturing CO2 emissions onboard machines, and converting said CO2 onsite at refueling stations to liquid fuel, and using that fuel for machines, the environmental economics suggest that this path is an attainable path to net zero emissions in difficult to electrify industries.
