Ammonia is critical to our food production ecosystem and the single most produced polluting chemical (~170 million tons per year) , while also holding the potential to become one of the most promising carbon-free and low-cost long term energy carrier . The industrial Haber-Bosch (H-B) process employs a Fe-based catalyst, fossil-fuel sourced H2, and requires harsh operating conditions (typically 673-723 K and 100-300 bar of pressure). The large-scale and centralized H-B process accounts for nearly 2% of the world's consumption of fossil fuels , and consequently over 1.44% of the global anthropogenic CO2 emissions . The development of smallscale processes that rely on renewable electricity as an energy source to sustainably produce the H2 feedstock would thus be transformative in several ways. It would provide critical technological support towards the audacious goal of carbon-free growth and ensuring the green transition. Two indispensable targets would be reached simultaneously, where renewable energy penetration is arduous -food production and clean mobility . A decentralized, low CAPEX NH3 synthesis process targeted at emerging markets with significant future population growth needs would also support the core U.N. sustainability goals.
