Conesa – Fertiberia Green Hydrogen Collaboration

Conesa Group and Fertiberia have launched a pioneering program designed to reduce carbon emissions in industrial tomato cultivation through the use of fertilizers produced from green hydrogen. This collaboration marks a significant step for two leaders in the Spanish agricultural sector, both of whom are aligning their operations with the United Nations Sustainable Development Goals (SDGs) to drive large-scale environmental change.

Conesa Group, a company with nearly 50 years of history in tomato processing, has made the sustainable development of its farms and those of its partners a primary strategic priority. By focusing on the minimization of the carbon footprint across its entire product cycle, Conesa aims to act as an agent of change in the industry. Similarly, Fertiberia, a leader in nutritional solutions, has established a firm commitment to reaching a Net Zero goal by 2035. Beyond its own operations, Fertiberia is actively promoting the decarbonization of other sectors by driving the development of green hydrogen and green ammonia as sustainable alternatives to fossil fuels.

The program utilizes Fertiberia’s “Impact Zero” fertilizer line. While these low-carbon fertilizers maintain the same performance characteristics as conventional products, their manufacturing process eliminates natural gas, replacing it with renewable energy. The core raw material is green ammonia, produced by capturing nitrogen from the air and using hydrogen extracted through highly sustainable, renewable-powered processes. These fertilizers are fully certified by AENOR to ensure transparency in their low-carbon origin.

The practical impact of this technology is already being measured. In 2025, the program covered an initial 300 hectares of fertilized area. By using these green hydrogen-based solutions, Conesa prevented the emission of 84.82 metric tons of CO₂e. For the farms fertilized exclusively with Impact Zero products, this represented a 54.7% reduction in the carbon footprint of the fertilization program (excluding machinery and other field emissions).

Building on this success, Conesa’s subsidiary, Agraz, is now expanding the use of these formulas to more than 2,200 hectares across Spain and Portugal. Facilitated by the distributor Mercoguadiana, the project also introduces Fertiberia TECH’s Neoforce line. This suite of biotechnological solutions—including biofertilizers and biostimulants—is designed to strengthen plant defenses and improve nutrient absorption. This approach allows the tomato crops to grow with better physiological balance and increased tolerance to climate stress, reducing the need for traditional chemical treatments while preserving soil biodiversity.

By combining green energy with advanced biotechnology, Conesa and Fertiberia are positioning the Iberian Peninsula at the forefront of sustainable agro-industry. The partnership demonstrates that large-scale industrial processing can successfully align with the European Green Deal and the “Farm to Fork” strategy, ensuring a competitive and low-emission future for the Mediterranean tomato.
