Nitricity is a startup addressing climate change. We use clean energy, natural elements, and innovative technology to produce high-performing fertilizers that reduce emissions, promote healthy soils, and help farmers improve yields. We are innovating in an essential chemical industry that supports global food systems. The bedrock of modern agriculture is the production, distribution, and application of the essential nutrients found in fertilizers. However, nitrogen fertilizer is currently made in coal- and gas-fired facilities located hundreds to thousands of miles away from farmers who need it. The $120B industry is responsible for as much as 6% of global CO2eq emissions. Nitricity Inc. has developed a new technology that produces fertilizer using air, water, renewable energy, and upcycled almond shells. Growers will have access to a more reliable, low cost, and environmentally friendly fertilizer supply. We are actively growing our team to help us turn this vision into a reality.
