June 24 (Reuters) - Exxon Mobil ( XOM ) and Air Liquide

have agreed to support the production of low-carbon hydrogen and

ammonia at the oil major's facility in Baytown, Texas, the

companies said on Monday.

Air Liquide, which supplies gases and services to

industries, will build and operate four Large Modular Air

separation units to supply 9,000 metric tons of oxygen and about

6,500 metric tons of nitrogen every day to the Texas facility to

help produce low-carbon hydrogen and ammonia.

Exxon's hydrogen production facility is expected to produce

1 billion cubic feet of low-carbon hydrogen daily and more than

1 million tons of ammonia annually.

The transportation of low-carbon hydrogen through Air

Liquide's existing pipeline network could enable growth in the

low-carbon hydrogen market, Exxon said.
