Green ammonia demonstrator - a pioneering commercially viable system for energy storage and ammonia productionSession
Green ammonia is the key to meeting the twin challenges of the 21st century. By switching to renewable electricity to make ammonia we could save over 40 million tonnes of CO₂ each year in Europe alone, or over 360 million tonnes worldwide. We can also burn ammonia to make electricity when the wind is not blowing.
In June 2018, Siemens launched a pioneering project to showcase the potential of using green ammonia for energy storage and demonstrate its viability in replacing the current environmentally harmful production method. Ammonia is produced in vast quantities worldwide for agricultural fertilisers but uses natural gas or other fossil fuels to provide both the hydrogen feedstock and the energy to power the synthesis process. As a result, ammonia production by these methods releases almost 1.5% of global CO₂ emissions.
‘Green ammonia’ is ammonia produced using only renewable electricity, water, and air. The Siemens Demonstrator shows the complete cycle of renewable power stored as ammonia and converted back to electricity. As a proof of concept, it has monumental potential in its ability to reduce harmful CO₂ emissions and provide a viable solution for storing renewable energy between seasons.
