The following fact sheet outlines one of the Department of Energy's series of actions, partnerships, and stakeholder commitments to help modernize the nation¹s natural gas transmission and distribution systems and reduce methane emissions. DOE will take the first step toward establishing energy efficiency standards for new natural gas compressor units by issuing a Request for Information (RFI). Several types of compressor technologies exist in the market today with varying efficiency levels; this is true for the compressors themselves and for the engines or turbines that drive them. DOE plans to examine each of these technologies to determine the viability of future energy efficiency standards. The initiative is the outcome of the five Methane Stakeholder Roundtables hosted by the White House and DOE at which leaders from industry, environmental organizations, state regulators, consumer groups, academia, and manufacturing and labor unions were asked to provide Administration and other representatives with their individual perspectives on opportunities to modernize natural gas infrastructure and reduce mid- and downstream methane emissions.
