ExxonMobil is pioneering the production of clean hydrogen fuel in Baytown, Texas, with plans to construct the world's largest hydrogen factory. The company's aim is to scale up hydrogen production to help achieve net-zero carbon emissions in the coming decades. Hydrogen, considered a clean fuel due to its byproduct of water vapor, is produced through various methods including natural gas reforming, electrolysis, biological processes, and solar-driven processes. Although currently relying on natural gas reforming, Exxon Mobil is partnering with Air Liquide to reduce carbon emissions at its hydrogen facility. This collaboration also involves increasing hydrogen and ammonia production for clean transportation. Hydrogen is regarded as a vital clean energy source for industrial and transport sectors not easily powered by renewable electricity. Exxon Mobil's push into hydrogen underscores its commitment to a sustainable future, despite facing regulatory challenges in the U.S. The company's efforts aim to popularize hydrogen as a key clean fuel option, thereby contributing to environmental preservation and a greener future.
