1. Short title This Act may be cited as the Hydrogen Aviation Strategy Act . 2. FAA and Department of Energy leadership on using hydrogen to increase aviation decarbonization (a) In general The Secretary of Transportation, acting primarily through the Administrator of the Federal Aviation Administration (in this Act referred to as the Administrator ), and jointly with the Secretary of Energy, shall exercise leadership in the creation of Federal and international policies, and shall conduct studies, relating to the safe and efficient use of hydrogen to increase aviation decarbonization and reduce air and noise pollution. (b) Exercise of leadership In carrying out subsection (a), the Secretary of Transportation, the Administrator, and the Secretary of Energy shall— (1) establish positions and goals for the use of hydrogen to increase aviation decarbonization; (2) through grant, contract, or interagency agreements, study the contribution the use of hydrogen would have on aviation decarbonization, including hydrogen as an input for conventional jet fuel, sustainable aviation fuel, and power to liquids or synthetic fuel, and on air pollution and noise pollution, and study ways of accelerating introduction of hydrogen-powered aircraft; (3) review grant eligibility requirements and other policies and requirements of the Federal Aviation Administration and the Department of Energy to identify ways to increase the use of hydrogen; (4) consider the needs of the aerospace industry, aviation suppliers, hydrogen producers, airlines, and other stakeholders when creating policies that enable the safe commercial deployment of hydrogen in aviation; (5) obtain input from the National Aeronautics and Space Administration, the aerospace industry, aviation suppliers, hydrogen producers, airlines, airport sponsors, fixed base operators, and other stakeholders regarding— (A) the efficient use of hydrogen to decarbonize aviation within United States airspace, including— (i) updating or modifying existing policies on such use
