Fertiliser from air and water with low carbon electricity
Nitrogen is an essential element of life and a part of all plant and animal proteins. It is commercially recovered from the atmosphere by combining it with hydrogen. Ammonia production, transport, and consumption is roughly a $100 billion annual worldwide business (2009) with an average scale of typical ammonia plant roughly 1000 MTPD. Approximately 80 % of ammonia is used as a fertilizer for crops, particularly corn and wheat. Currently hydrogen for ammonia manufacture is recovered from natural gas, but water could be utilized as an alternative source. In fact at least five commercial ammonia plants were in operation in 1980 all based on water electrolysis. The energy use and capital cost are roughly comparable with electrochemical and steam reforming routes (in 1980 the cost of an electrolysis-based ammonia plant rated at 300 MTPD was stated to be $80M, which is $174M in 2013 currency). Based on techno-economic calculations, electroammonia becomes interesting when long-term renewable electricity prices are below 30 $/MWh.
