Call it a rebranding of "energy dominance [whitehouse.gov]." In a press release published on Tuesday, two Department of Energy officials used the terms "freedom gas" and "molecules of US freedom" to replace your average, everyday term "natural gas."
The press release was fairly standard [energy.gov], announcing the expansion of a Liquified Natural Gas (LNG) terminal at the Freeport facility on Quintana Island, Texas. It would have gone unnoticed had an E&E News reporter [twitter.com] not noted the unique metonymy "molecules of US freedom."
DOE Assistant Secretary for Fossil Energy Steven Winberg is quoted as saying, "With the US in another year of record-setting natural gas production, I am pleased that the Department of Energy is doing what it can to promote an efficient regulatory system that allows for molecules of US freedom to be exported to the world."
