ExxonMobil successfully demonstrated the commercial testing of pyrolysis burners capable of operating on up to 100% hydrogen fuel at its olefins plant in Baytown, Texas. This marks the first time this technology has been proven at an industrial scale globally.
A total of 44 burners were installed in one of the plant's steam cracking furnaces, and testing at 98% hydrogen concentration produced ethylene and other olefins identical to those from traditional methods. This achievement demonstrated a 90% reduction in direct CO2 emissions from the furnace during tests.
This breakthrough is a critical step in decarbonizing hard-to-abate sectors like the chemical industry, which requires high temperatures for processes like olefin production. ExxonMobil plans to install these burners in additional furnaces at Baytown and is developing a plant to produce virtually carbon-free hydrogen with 98% CO2 capture.
