Chile’s Comasa files grid capacity request for green fertilizer push

Chile’s Comasa has filed a grid capacity request for a green fertilizer project, BNamericas reported. The pilot phase is designed to produce up to 2,000 metric tons a year of ammonia by combining hydrogen from electrolysis with nitrogen from air separation. The ammonia would then be combined with flue gas and ash from a power plant to make fertilizer.

Chile’s environmental review service, SEA, told Comasa it did not need a full evaluation to expand the pilot. The second phase would produce up to 40,000 metric tons a year of fertilizer, using 10 megawatts of electrolysis capacity and producing 7,300 metric tons a year of ammonia. That phase would make hydrogen on site as well as buy it.

Field validation of the fertilizers is due to begin in 2027, according to the report.
