The U.S. can and should take a leadership role in producing and exporting cleaner fuels to the world, including biomethane (or renewable methane), hydrogen, biomass-based diesel fuels, and reduced-carbon liquefied natural gas (LNG). No country is better positioned than the United States to supply these cleaner fuels. Deploying existing U.S. infrastructure—including millions of miles of pipelines already carrying natural gas, hydrogen, biomethane, CO 2 and other commodities relevant for cleaner energy, numerous current and potential onshore and offshore sites for carbon capture, use and sequestration (CCUS), and scores of major energy processing and export facilities—and the deep human capital that already exists in the country's energy workforce, gives the United States a unique opportunity to provide cleaner fuels to the world.
