Synthetic fertilisers boost crop yields but leave a heavy carbon footprint. Made using fossil fuels, they account for a considerable 1.4% of annual global CO2 emissions, according to multiple sources. To reduce the world’s dependence on fossil-fuel based fertilisers, some in the agri-food sector are looking at low-carbon fertilisers as a potential solution. Instead of using natural gas, emission-free hydrogen is used. But while low-carbon fertilisers look promising, cost, speed and scale issues have stood in the way of widespread adoption.

With war in Ukraine continuing to restrict global supplies and push prices up, the agri-food sector is increasingly motivated to move away from fossil-fuel based fertilisers. But with policy-making in this sphere slow, agri-food companies may have to come together to kick-start green hydrogen projects on their own. 

This 50-minute digital dialogue looked at how food retailers, processors, and farmers can overcome some of the obstacles standing in the way of commercialising low-carbon fertiliser by using an end-to-end value chain approach, developed by the European Green Hydrogen Acceleration Center (EGHAC).
