Wind turbine is being used to produce zero-carbon "green ammonia" fertilizer
A Minnesota-based facility is testing the use of wind energy to produce green ammonia fertilizer, aiming to reduce the agricultural sector's reliance on fossil fuels. This shift is driven by both climate goals and the need to mitigate risks from volatile international supply chains.
Why it matters
Decarbonizing fertilizer production is critical for global food security and reducing the carbon footprint of the agricultural industry.
Beyond climate targets, volatile international markets are also a primary driver of the sector’s shift.
Will a facility in Minnesota prove that agriculture can save money while going green ?
Global food production has relied on one chemical reaction for over a century.
This is known as the Haber-Bosch process , and it was invented in the early 1900s.
The key is to create synthetic ammonia fertilizer by combining atmospheric nitrogen with natural gas or coal.
This process is extremely heat-intensive and accounts for up to 2% of total global greenhouse gas emissions.
While it is highly unsustainable, it has doubled the Earth’s food-carrying capacity and still feeds almost 50% of the population.
Experts predict that the population will peak at 10.3 billion by the mid-2080s.
Beyond producing enough food to feed all these people, other factors also impact the world’s food security.
