A national initiative launched in Punjab aims to test green ammonia as a nitrogen source on 10,000 acres across India this rabi season, with 1,800 demonstrations in Punjab alone.
CropsDemonstrations in Mahendergarh district, run by the local Krishi Vigyan Kendra, will measure whether liquid green ammonia improves nitrogen use efficiency and returns in mustard compared with urea.
CropsA Rothamsted Research study finds fertiliser manufacture is up to 47% of the energy-related footprint on arable farms, and that best-practice nitrogen use would cut fertiliser-linked energy by 16% to 40%.
Siba Prasad Mohanty, managing director of Hindustan Urvarak & Rasayan, argues India must secure urea's feedstock, through green ammonia at Barauni and coal gasification at Sindri, not only its output.
AgrotechIceland's Atmonia makes ammonia from nitrogen and water in one electrochemical step, without producing hydrogen first, and aims for a container unit making about 150 tons a year on farms.
Facet Amtech has raised a A$3 million seed round to pilot a catalyst that makes ammonia, the building block of nitrogen fertiliser, directly from air and water, without a separate hydrogen plant, and aims to undercut fossil-based ammonia on cost alone.
