Abstract

Geo-NH₃ is a novel technology that reduces nitrates to ammonia using iron-rich rocks under natural geothermal heat and pressure, without the need for external hydrogen, electricity, or heating. It features low cost, zero carbon emissions, and resource recycling benefits. With immense potential, it can enable sustainable ammonia production for up to 2.42 million years, with broad applications in agriculture, energy, and chemical industries. However, further optimization and research are needed to improve reaction efficiency, address practical application challenges, and evaluate long-term environmental impacts.
