Biocoal

Biocoal is a coal similar to the coal. Difference stems from the fact that biocoal is produced artificially from biomass by means of hydrothermal carbonisation (HTC) technology and compared to fossil coal it offers several below-stated advantages.

Biocoal is ideal for de-centralised, local utilisation of biomass and biowaste with high humidity content, such as sludge from water-treatment plants, waste from food industry, including breweries or distilleries and also agriculture waste. 

Thanks to the volume reduction by up to 75% and increased energy density there are options for longer-distance transporting of biocoal.

Biocoal meets the requirements on biomass stipulated by German laws on renewable energy sources (EEG) and on heating with renewable energy sources (EEWärmeG). Through incineration of one tonne of biocoal the user will spare approximately 2.5 tonnes of CO2 emissions.

Advantages and Characteristics of HTC Coal

  • Biocoal is a highly homogenous fuel produced from highly heterogeneous biomass
  • CO2-neutral source of energy
  • ~ 75% of biomass energy is transferred to the coal
  • High calorific value – up to 25 MJ/kg can be achieved when grasses or straw is used
  • Production of coal with defined calorific value 
  • High incineration efficiency with low NOx emissions
  • Very low content of toxic materials, sulphur and heavy metals
  • Lower volume for storing when compared to biomass
  • Unlike biomass it is not subject to degradation 
  • Lower transportation costs when compared to biomass 
  • Removes problems with biomass clinkering in boilers
  • High temperature of ash fluxing ~ 1.400 °
