N2 Applied is a Norwegian technology development company, with the head office in Oslo and a test centre in Svene. N2 Applied is a catalyst and an incubator for high-tech initiatives related to nitrogen. N2 Applied has developed technology to enable on-farm processing of manure or biogas digestate to produce a nitrogen fertiliser. Using renewable electricity and air, a plasma reactor fixes nitrogen by splitting the N2 and O2 molecules in air into N and O atoms to generate nitrogen oxides. These nitrogen oxides react with ammonia in manure or digestate to form ammonium nitrate, so lowering pH and stabilising the nitrogen, reducing ammonia and greenhouse gas emissions during storage and field application. After solid/liquid separation the liquid fraction of manure or digestate can be managed as a liquid nitrogen fertiliser, compatible with organic farming (depending on the manure and digestate substrate inputs). Most of the phosphorus will remain in the solid fraction. N2 Applied joins the ESPP network to share knowledge and collaborate on efficient and sustainable nutrient management in agriculture.
