Discussion Driving Forces for New Investments The most important influences are the situation on the coke market, the age of existing plants in connection with considerations referring to medium- and long-term cost development of maintenance cost. In case of new batteries to be built capital and operation expenses are taken as a basis for decisions on technical concepts. Last but not least more and more stringent environmental requirements have to be taken into account, which consequently leads to the installation of coke oven batteries providing most modern technologies in this regard, too. Coke Market A strong increasing demand for coke is indirectly demonstrated in figure 1. An amount of more than 67% of oxygen steel, which is based on hot metal production in blast furnaces, is a clear indication that this classical production route keeps its dominant role. In relation to the growth of steel production as shown here, the annual amount of coke produced rose from 350 million mt in 2003 worldwide to more than 540 million mt in 2008. Demand and availability of coke during this period was not completely outbalanced which led to the well known development of the coke price on the spot market as illustrated in figure 2. It shows tremendous values still in 2008 with a strong decrease after the beginning of the crisis. The price FOB China is kept thereafter on a constant value, which obviously represents an artificial figure, keeping in mind that the amount of exported coke from China has dropped down to some 10-thousand tons of coke per month in comparison to average values of about 1.2 million tons per month in the foregoing period. A recovery of the market is visualized by the increasing coke price CFR Europe, which represents a realistic relation between demand and availability and also the Chinese coke price is increasing at the beginning of 2010, despite the fact that only small portions have been exported. 2
