ExxonMobil™ Low Carbon Ammonia

Reducing emissions in hard-to-abate sectors

A reliable path to carbon reduction
With increasing pressure to reduce carbon emissions while meeting production targets, manufacturing, power-generation and transportation need a lower-carbon feedstock and fuel-switching solution. Supply reliability is crucial to meet the demands of growing markets looking to make the energy transition. That is why ExxonMobil is working towards building the world’s largest low-carbon hydrogen facility with low-carbon intensity ammonia available for offtake.

ExxonMobil™ Low Carbon Ammonia is an advantaged carbon reduction solution that leverages our integrated value chain, starting with our lower-emission natural gas from the Permian Basin.2 We can then capture and sequester CO2 associated with the ammonia production, which further helps customers meet their specific emission goals. Our value chain integration allows ExxonMobil to manage emissions across the production process delivering a lower carbon intensity solution.

We offer comprehensive technical analysis and economic insights to help customers frame their projects (including risk-benefit analysis, incentive qualification, regulation navigation, and CI calculations) and progress toward their emission-reduction goals.

Increasing capabilities to decrease emissions

In Baytown, Texas, we're testing out the technologies to derisk our customers' projects. Today we are collaborating with third parties to help develop this solution, working with companies like SK Inc. Materials of Korea to advance our planned ammonia project in Baytown.

When completed, our Baytown facility is expected to be the world's largest producer of low-carbon hydrogen and will provide customers with ammonia offtake options.1

With demand expected to increase between two- and three-times today’s levels by 2050, according to various IEA development scenarios, the Baytown low-carbon intensity ammonia project, where CO2 associated with production of such ammonia is captured and sequestered, is well positioned to allow ExxonMobil to reliably and safely produce sufficient supplies to the market.

The ExxonMobil difference

Customers will benefit from the full suite of capabilities that have been developed from more than 140 years of delivering differentiated products to the market. Here’s a look at some of those capabilities:

Integration

With our advantaged lower-emission natural gas from the Permian Basin, we will produce a lower-carbon intensity ammonia using carbon capture and storage at our Baytown facility to produce low-carbon intensity hydrogen that is then transformed to ammonia. Our customers will see minimal equipment retrofitting and plant disruption as they integrate ammonia into their facilities.
Integration

Scale

There is no project too large or complex for our experts, as our own Baytown facility serves as a roadmap for the industry. It is anticipated to be the largest low-carbon hydrogen facility in the world and it will provide a reliable source of supply for years to come.
Scale

Commercial viability

ExxonMobil is leading in the creation of new markets for low-carbon intensity ammonia. Already we have secured agreements, including with Japan’s Mitsubishi to offtake our ammonia, delivering real-world progress in this space.
