Through this partnership, Keppel and Exxon Mobil look to leverage their experience to deliver low or zero-carbon hydrogen and ammonia solutions to support Singapore’s quest to decarbonise its power sector.

Exxon Mobil is planning a CCS hydrogen & ammonia production facility at its existing complex in Baytown, Texas, with operations to begin in 2027-8. This week, Korea-based SK Inc. Materials announced they would act as off taker for the CCS ammonia, which will be imported to Korea for use in coal co-combustion.

Shell will acquire a 35% stake and operatorship of the Green Energy Oman (GEO) project, a 25 GW renewable ammonia supergiant under development on the Oman coast. The news is the latest in a series of ammonia energy announcements from the oil & gas majors.

This week we explore three new partnerships for CCS-based ammonia production in the USA:

• CF Industries, ExxonMobil & EnLink Midstream, for decarbonisation of the Donaldsonville production plant in Louisiana.
• Air Liquide, Chevron, LyondellBasell, and Uniper for a new production facility on the Gulf Coast.
• And Tallgrass & Equinor for the potential production of hydrogen and ammonia across the USA, leveraging Tallgrass’ existing infrastructure network.

ExxonMobil, Grieg Edge, North Ammonia, and GreenH will explore options to transform Exxon’s existing Slagen terminal into a production & distribution hub for renewable ammonia and hydrogen maritime fuels. The group has identified the potential to produce 200,000 tonnes of electrolytic hydrogen production per year at the site, as well as distributing 100,000 tonnes per year of renewable ammonia. Exxon’s wider plans for low-carbon ammonia also include two large-scale production hubs (one each in the US and the UK).

Two recent announcements show Singapore emerging as a center for development of ammonia as a maritime fuel. In both cases, multi-party coalitions, with Singaporean connections, are focusing on ground-breaking work.
