The Future of Natural Gas Infrastructure Development in

The Future of Natural Gas Infrastructure Development in the United States ● ● ● ● Objective Examine plausible uncertainties in the future of natural gas (NG) infrastructure development in the United States Approach Couple a human-Earth system model (GCAM-USA) with an NG infrastructure model (NANGAM) Assess magnitude of investments in interstate NG pipeline infrastructure and pipeline flows in the U. S. Examine interstate pipeline infrastructure under a range of internally consistent socioeconomic scenarios Impact This study adds to analysis of U. S. NG pipeline infrastructure development the interactions of the NG sector with other sectors Results indicate that existing pipeline capacity is insufficient to satisfy future demand for NG under a range of socioeconomic scenarios and investments will be required In addition, infrastructure investment needs vary substantially by region across different socioeconomic scenarios Natural gas net flows (bcm) in 2050 for major gas pipelines in Reference and Low domestic natural gas demand scenarios. Thickness of bars indicates magnitude of flows; arrows indicate direction. Circled numbers show net outflows from the mid-Atlantic region.
