Key Highlights
- Plasma‑based technology oxidises atmospheric nitrogen without fossil fuels.
- Energy consumption cut by up to 90 % compared with conventional nitrification.
- Projected $2 million prize will accelerate scale‑up in Europe through farmer‑owned cooperatives.
- Potential to slash fertilizer‑related CO₂ emissions, which account for 2.7 % of global totals.
Detailed Insights
Swedish physicist Gustaf Forsberg, founder of NitroCapt, engineered a system that harnesses plasma to extract nitrogen directly from air, driven solely by renewable electricity. The process eliminates the combustion‑based steps that traditionally dominate nitrogen fertilizer production, thereby dramatically curbing greenhouse‑gas output. The company maintains a functioning pilot plant in Uppsala, Sweden, where it partners with the Swedish University of Agricultural Sciences and its own farm for real‑world testing. With the $2 million Food Planet Prize, NitroCapt plans to scale production by the end of 2026, targeting initially the European market and subsequently engaging governments, NGOs, or private enterprises in other regions.
The 2025 Food Planet Prize, organised by the Curt Bergfors Foundation, acknowledges technologies that promise large‑scale environmental returns within food systems. Its winner, NitroCapt, joins a cohort of finalists—including adaptive symbiotic technologies and regenerative rice systems—that collectively aim to reduce emissions, waste, and pesticide reliance.
Key Concepts
Plasma‑based nitrogen fixation: A non‑thermal plasma process that converts atmospheric nitrogen into usable fertilizer compounds without combustion.
Energy intensity in fertilizer production: The amount of electricity and fossil fuel required to manufacture nitrogen fertilizers, often exceeding one‑tenth of that needed for alternative clean-energy applications.
Geopolitical supply shocks: Disruptions in fertilizer availability due to conflicts or trade restrictions, exemplified by the Ukraine war’s impact on European markets.
Climate‑resilient agriculture: Farming practices that adapt to changing climate conditions while limiting environmental footprints.
Food security nexus: The interdependence between stable food supplies, sustainable production methods, and global political stability.
