Air Liquide joins ExxonMobil’s low-carbon hydrogen project

ExxonMobil has announced that it has signed an agreement with Air Liquide to support its production of low-carbon ammonia and hydrogen at its Baytown facility in Texas.

ExxonMobil, the maker of the Mobil lubricant and grease range, is planning to build the world’s biggest facility for producing hydrogen. When completed, it should produce low-carbon hydrogen at a rate of a billion cubic feet a day together with a million tons of ammonia each year. The company also expects to capture at least 98% of the CO2 emissions associated with this production.

The new partnership will see Air Liquide use its current pipeline network to supply low-carbon hydrogen to customers on the US Gulf Coast, to help them decarbonise their operations. Air Liquide will also construct and run four large modular air separation units (LMAs), with the carbon footprint of these being minimised through the use of low-carbon electricity. These LMAs will supply around 6,500 metric tons of nitrogen and 9,000 metric tons of oxygen each day.

The president for low-carbon solutions at ExxonMobil, Dan Ammann, said:

“Momentum continues to build for the world’s largest low-carbon hydrogen project and the emerging hydrogen market. This partnership with Air Liquide further strengthens our Baytown project by enabling hydrogen distribution through existing networks and securing key feedstocks.”

A final investment decision for the project will be made later, subject to securing regulatory approval and government policies being sufficiently supportive. ExxonMobil says it aims to reduce its operated assets’ Scope 1 and 2 emissions to net-zero by 2050.
