 Here are some studies that look at retrofitting natural gas ammonia plants to green ammonia plants: 

 

Sustainability Assessment of Green Ammonia Production

This study found that green ammonia can be an important part of decarbonization efforts, especially when natural gas costs and carbon prices increase. It also found that efficient ammonia-fueled systems are important for the entire supply chain. 

 

Innovative Revamping of Ammonia plants for Capacity up and ...

This study found that retrofitting ammonia plants can reduce energy use, NOx and CO2 emissions, and total steam demand. The study also recommended adding a dedicated ASU for pure oxygen and nitrogen, and cryogenic purification for drying and purifying synthesis gas. 

 

Green ammonia production-enabled demand flexibility in ...

This study found that coupling ammonia plants with other systems can decrease electricity costs and increase ammonia profits. It also found that ammonia fuel cells can provide power in emergencies. 

 

Green ammonia is made from non-fossil fuel sources using renewable power. It can be used as an energy carrier and is burned in power production plants. Some countries, including Japan, Australia, the Netherlands, and the United Kingdom, have plans to use green ammonia to store and export renewable energy
