In 2007 the idea of the mobile acidification system started.
In 2009, 5 prototypes of SyreN were set into production and were tested after the Vera protocol in 2010.
When the VERA protocol proved that field acidification had the same emission as injection in grass, SyreN was added to the Danish technology list, where from the sale had a strong growth.
In 2011, there were 19 systems in the field.
In 2012, there were 52 systems, furthermore the idea of adding ammonia to liquid manure were born.
During 2012 the prototype of SyreN+ was made, this were an extension on SyreN and had the purpose to youse ammonia as an N fertilizer.
In 2013, Bthere were 86 SyreN running and the first SyreN+ was started in the field.
