US Firm Uses Solar Energy to Make Sustainable Nitrogen Fertiliser

California-based Nitricity has created an experimental reactor that produces economical and ecological nitrogen fertilizers using solar energy. Their on-site fertilizer production eliminates the emissions of fertilizer transport and provides a sustainable alternative to the Haber-Bosch process, which uses fossil fuels to fix nitrogen.
The nitrogen extracted from the air enables Nitricity to produce nitric acid, the most essential nutrient in fertilizers that plants use to grow all of our food.

In October 2021, the company began commercial operations with an installation of 144 solar panels. On its official website, Nitricity then provided the results of an experimental study on its pilot project in Fresno, California. The starting solar system was a complex of 16 ground panels producing 75-85V and a maximum power of 2.4kW.
The plant was connected directly to an underground…
