The Comptroller General of the United States shall conduct a study on existing natural gas pipeline systems that, as a result of hydrogen-natural gas blending, contain a percentage of hydrogen that is greater than 5 percent by volume to identify the changes that operators have implemented, including— modifications or alternatives to— odorants and leak-detection methods; pipeline materials; and operational standards; and modifications to pipeline infrastructure. The study under subsection
(a)shall include— an identification of any technical challenges with repurposing existing natural gas infrastructure to allow such infrastructure to be used for hydrogen-natural gas blended service; and an examination of hydrogen-natural gas blended pipeline systems currently operating, including in the United States, the United Kingdom, Canada, Europe, Australia, and Hong Kong. In conducting the study under subsection (a), the Comptroller General shall consider— any changes that domestic and international operators of natural gas pipeline systems have implemented to the processes, pipeline materials, metering, and operational standards used by such operators to account for the operation and integrity of natural gas pipeline systems that use a hydrogen content at variable percentages above 5 percent by volume; and how such operators have taken into account the effects of hydrogen-natural gas blending on different types of— natural gas pipeline systems materials, including cast iron, steel, composite pipe, and plastic pipe; and components of such systems, including valves and meters. Not later than 1 year after the date of enactment of this Act, the Comptroller General shall submit to the Committee on Transportation and Infrastructure and the Committee on Energy and Commerce of the House of Representatives and the Committee on Commerce, Science, and Transportation of the Senate a report on the results of the study conducted under subsection (a). The results of the study under subsection
(a)should inform the rulemaking efforts of the Secretary relating to hydrogen-natural gas blending. The Secretary may determine that rulemaking efforts related to hydrogen should be advanced before completion of the study under subsection (a). Nothing in this section shall be construed to prohibit or otherwise limit the authority of the Secretary to issue regulations relating to hydrogen prior to the submission of the report under subsection (d).
