AGDC is studying feasibility of producing carbon-free ammonia

07 october 2022
The Alaska Gasline Development Corporation (AGDC) has announced that it will study the feasibility of producing ammonia in the state’s Cook Inlet region with Japan’s Mitsubishi Corp, TOYO Engineering Corp and Hilcorp Alaska.
According to the Alaska state-owned AGDC, the four companies agreed to evaluate the commercial feasibility of utilizing North Slope natural gas delivered to South Central Alaska via the Alaska LNG Project to produce carbon-free ammonia.
‘Carbon dioxide emissions from the production of the hydrogen-rich fuel can be captured and stored underground in the Cook Inlet basin, which has “world-class carbon sequestration potential,’ added AGDC.
Japan, the world’s fifth-biggest CO2 emitter, is targeting growing its demand for fuel ammonia, which does not emit CO2 when burnt for energy, to 3 million tonnes a year by 2030 from zero now, reflecting its 2050 goal to become carbon neutral.
AGDC pointed out that the costs and emissions associated with shipping ammonia to Asian markets from Alaska are lower compared to the U.S. Gulf Coast.
Japanese companies are also looking to invest in the Canadian province of Alberta to produce ammonia and methanol to build global supply chains of greener energy to fight climate change.
