with coal Other alternative fuels tend to have greater quality fluctuations due to seasonal influences. Subcoal is hydrophobic and can thus be stored outside. This allows Subcoal to be mixed with the primary fuel in uncovered areas e.g. in the external coal storage area. The existing dosing equipment and grinding media can be used to transport the Subcoal into the power station. Costs and savings The gate fee for the waste streams and the costs for logistics have to be taken into account. Typically, in Europe, the price for Subcoal (CIF) fluctuates between €1 and €2.50 per gigajoule. The fluctuation is dependent on the input prices for the waste streams which are used and the production steps. See also.
