A chemical traditionally used in the fertiliser industry, ammonia is now also entering the realm of energy as a way to store and transport hydrogen, or as an alternative transport fuel in its own right.
Composed of hydrogen and nitrogen, ammonia (NH3) liquefies at only -33°C under ambient pressure compared to -253°C for hydrogen, making it an attractive candidate to transport hydrogen over long distances.
However, regulatory and financial support will be needed in order to bring down costs and clean up ammonia production. Read this EURACTIV special report to find out more.
The fertiliser industry is increasingly cited as an ideal testing ground for the EU’s upcoming carbon border levy, due to be tabled in June. But industry figures warn this risks causing an increase in food prices that could trigger social unrest.
Ammonia has until now been used chiefly in the fertiliser industry as a way to return nitrogen to the soil. But it also has potential in boosting renewables – both as a replacement for hydrogen in long haul shipping and as a way of storing and transporting hydrogen.
The fertilizer industry has identified the most promising technologies for making green fertilizers. The challenge is to make the business case for decarbonised products. This can be achieved by driving down the cost and addressing technical challenges on the supply …
