Liquefied natural gas (LNG) is natural gas that has been cooled to a liquid state, at about -260° Fahrenheit, for shipping and storage. The volume of natural gas in its liquid state is about 600 times smaller than its volume in its gaseous state. Liquefying natural gas is a way to move natural gas long distances when pipeline transport is not feasible. In its compact liquid form, natural gas can be shipped in special tankers to terminals around the world for distribution.
In April 2023, a Request for Information (RFI) was issued by DOE Office of Fossil Energy Carbon Management focused on opportunities to reduce emissions related to LNG. The purpose of the RFI was to solicit feedback from industry members, investors, project developers, nongovernmental organizations, academia, research laboratories, government agencies, and other stakeholders on technologies and strategies that LNG companies are deploying, or could deploy, to reduce greenhouse gas emissions and other air pollutants. This includes emissions of carbon dioxide, methane, criteria pollutants, and hazardous air pollutants that occur during production through transportation of natural gas delivered to a liquefaction facility; at liquefaction facilities; and during the loading, transport, and delivery of LNG to a regasification facility.
This RFI is being utilized to support the identification of potential research and development pathways related to emissions quantification and mitigation, along with factors that might further abate emissions and other environmental impacts from LNG facilities and transport infrastructure.
