The U.S. has seen substantial growth in hydrogen production, with industries like petroleum and chemicals utilizing hydrogen for various purposes. However, the transportation industry, especially trucking, has been slow to adopt hydrogen fuel despite its increasing availability. There is a growing interest in using hydrogen in challenging-to-electrify sectors like aviation and shipping, with major airlines showing intent to transition to sustainable fuels. Companies in the trucking industry are making strides by developing hydrogen-powered vehicles and providing infrastructure like electrolyzers for refueling stations. While most hydrogen produced in the U.S. is carbon-intensive 'gray hydrogen,' there are plans for blue hydrogen facilities like Air Products’ Louisiana Clean Energy Complex and Exxon Mobil’s Baytown facility to reduce emissions. Policy support, such as tax incentives from the Inflation Reduction Act, is crucial for furthering hydrogen production and transitioning to cleaner fuel sources.
