DEBYE empowers farmers to locally produce zero carbon nitrogen fertilisers using only air, water and electricity.


The Haber-Bosch Process

Nitrogen fertilisers play a critical role in modern agriculture, helping to boost crop yields and ensure food security for growing population. However, the manufacture, transportation and application of synthetic nitrogen fertilisers also have significant environmental and climate implications, which account for a total of about 5% of global greenhouse gas emissions, equivalent to 1.33 gigatonnes of carbon dioxide for 2021. 


483 Mt CO2

The manufacture by the Haber-Bosch process relies on fossil fuels, accounts for 483 million tonnes of carbon dioxide equivalent emissions.


13 Mt CO2

Transportation accounts for 13.1 million tonnes of carbon dioxide equivalent emissions.


829 Mt CO2

Application accounts for 829 million tonnes of carbon dioxide equivalent emissions.


Direct Nitrogen Capture by Electricity

Nature provides an elegant solution: when lightning strikes water, it captures nitrogen in the form of nitrates, which serve as a natural source of potent nitrogen fertiliser for plants. Inspired by Nature, we develop a modular and containerized system that uses only air, water, and electricity to produce nitrate fertiliser.

Our Process


Nitrogen Fixation

The lightning breaks the nitrogen and oxygen molecules to make nitrogen oxide gases.


Nitrate Formation

The nitrogen oxides react with water to form dilute nitric acid.


Compound Fertiliser

The dilute nitric acid is combined with minerals to make desired fertiliser such as calcium nitrate.

Why electrification?

Many governments have set ambitious targets to achieve net-zero emissions by 2050 or earlier. The agricultural sector is a big part of the problem due to use of synthetic fertilisers and livestock production. To encourage more countries to commit to the net-zero goal, the European Union will introduce carbon taxes from 2026 specifically targeting fertilisers under the Carbon Border Adjustment Mechanism (CBAM). For farmers, this implies increased pressure to manage agricultural carbon footprints and rising fertiliser prices linked to the carbon market price

Debye’s process enables decarbonization and decentralization of nitrogen fertilizer production, and can be the backbone of sustainable farming businesses.



Our process is sustainable, and avoids minimum 10 kg CO 2 emission per kilogram nitrogen when integrated with renewable energy.


On-site and on-demand production reduces the reliance on resource and capital-intensive fertiliser factories, associated high-cost distribution networks and supply chain risks.
