ExxonMobil plans H₂ project at Houston carbon-capture hub

ExxonMobil is proposing a plant in Houston that would produce close to 800,000 m³ per day of blue hydrogen from natural gas. To make the H₂ blue, the firm would capture the carbon dioxide by-product and permanently store it underground. ExxonMobil tells C&EN that the CO₂ would not be used for enhanced oil recovery. The firm plans to use the H₂ as a feedstock for olefins and other chemicals, which would then be considered low-carbon alternatives. The project is part of a planned multiparty hub for carbon capture and storage that ExxonMobil has proposed for the Houston area.
