However, to take this gas from the air and into a bag of fertiliser takes a huge amount of energy. The Haber-Bosch process, which converts nitrogen and hydrogen into ammonia as a crucial step in creating fertilisers, uses between 1% and 2% of all energy generated globally by some estimates. Consequently, the cost of producing nitrogen fertiliser is directly linked to the cost of fuel.
