WILHELMSHAVEN. Late last year Novatek and Uniper signed a benchmark paper for the first German-Russian supply chain for reduced C02 ammonia. The intention is to supply Uniper customers in Germany and in North West Europe in the future. Novatek is constructing a plant in Siberia to manufacture reduced CO2 ammonia. At the same time, Uniper is involved in the planning of an ammonia import terminal in Wilhelmshaven that will convert ammonia into gaseous hydrogen, which can then be fed into a pipeline system.
