Prototype Device Converts Air Into Fertilizer, Cutting Carbon Emissions

Stanford researchers unveil a sustainable method to produce ammonia, potentially transforming agriculture and energy industries.

The device uses wind energy to extract nitrogen and hydrogen from air and water vapor, producing ammonia at room temperature and standard pressure.
Traditional ammonia production accounts for 1% of annual global carbon emissions and consumes 2% of global energy, making this innovation a low-carbon alternative.
Researchers envision integrating the portable device into irrigation systems, allowing farmers to generate fertilizer on-site without relying on industrial supply chains.
Laboratory tests showed the device can achieve ammonia concentrations sufficient for greenhouse hydroponic fertilizer in just two hours, with plans to scale production for broader applications.
Ammonia's potential extends beyond agriculture, serving as a cleaner energy carrier for decarbonizing industries like shipping and power generation.
