The invention could help keep emissions in line with upcoming EPA regulations as the agency seeks to further limit methane, carbon dioxide, and other greenhouse gases. In a 72-hour natural gas pump simulation, McCulloch said his invention was successful, as reported by the Daily Times. A real-world test was not possible, he said, because he couldn’t put exhaust into the production pipeline, which his invention does.
The inventor reported he is now in talks with ConocoPhillips.
