1. Short title This Act may be cited as the Hydrogen Infrastructure Finance and Innovation Act . 2. Study Not later than 18 months after the date of enactment of this Act, the Secretary of Energy, in coordination with the Administrator of the Environmental Protection Agency, the Chair of the Council on Environmental Quality, the Administrator of the Energy Information Administration, and the heads of other relevant Federal agencies, shall conduct a study subject to notice and public comment— (1) to fully assess and report the potential layout of pipeline corridors, including existing and new infrastructure, that— (A) are robust against a range of projected hydrogen demand futures; and (B) reflect the potential to site within, or adjacent to, existing pipeline or other linear infrastructure corridors; (2) to assess the costs associated with each infrastructure scenario described in paragraph (1); (3) to synthesize the results from research, development, and demonstration projects on materials and metallurgy for transporting and storing hydrogen and hydrogen-based fuels, such as ammonia; (4) to determine outstanding questions with regard to research, development, and demonstration of infrastructure for transporting and storing hydrogen and hydrogen-based fuels, such as ammonia; (5) to investigate the behavior and environmental impact of hydrogen leakage in pipelines and from geologic storage sites and nongeologic storage equipment; (6) to determine best practices for the construction and maintenance of hydrogen pipelines; (7) to determine the reduction in carbon intensity at various levels of hydrogen blending into the natural gas network
