Amogy, GS E&C venture secures NH3 for S Korean power
London, 8 October (Argus) — US technology firm Amogy and South Korea's GS
Engineering and Construction (GS E&C) have agreed to buy 1,500t of renewable
ammonia from Lotte Fine Chemical (LFC) for a planned 1MW power plant in Pohang,
South Korea. The firms signed the deal through their Amun Energy joint venture,
following an initial agreement last month. LFC will supply the ammonia over one
year from 2027. The plant will sell power directly to businesses in the
surrounding industrial complex. The 1,500t contain about 7,750MWh of energy on a
lower heating value basis. At an electrical efficiency of 30-45pc, covering
ammonia cracking combined with hydrogen engines or fuel cells, it could generate
2,300-3,500MWh, based on Argus calculations. This equates to a capacity factor
of 27-40pc for a 1MW unit. Operating at full load throughout the year would
require about 3,800-5,700t of ammonia. The firms have pitched the technology as
a source of "round-the-clock power" for industrial sites and data centres, but
the contracted volume suggests a gradual ramp-up. The partners plan to expand
capacity to 10MW in 2028, with a longer-term target of up to 40MW. Scaling up
the first year's contracted supply would imply ammonia demand of 15,000 t/yr and
60,000 t/yr, respectively. At full load, the 10MW plant would require about
38,000-57,000 t/yr, while the 40MW plant would need around 151,000-226,000 t/yr
(see table) . A 40MW plant would generate 93-140 GWh/yr at the 1MW unit's
implied utilisation, or about 350 GWh/yr at full load. Seoul plans to procure
500 GWh/yr for 2029-44 in its next clean hydrogen power tender. Dedicated
ammonia-to-power plants remain eligible after the government ended support for
coal-ammonia co-firing in August. LFC received the first export cargo from
Envision Energy's renewable ammonia plant in Chifeng, China, earlier this year
and is expanding ammonia storage at Ulsan. By Chingis Idrissov Potential ammonia
