The performance of Europe’s biggest straw-fuelled power plant hardly exceeds that of Pécs Power Plant. This unit is found in Ely, England and its output is 40 MW.

About biomass in general

From energy point of view, biomass is the continuously renewable energy source originating from living organisms.

The most widely used type is wood, although agricultural residues, animal products, industrial and municipal combustible wastes, plants the seed of which can be used to produce fuel as well as energy crops developed for this very purpose, like energy cane or energy poplar, also belong here. 
By-products, wastes that can be used as biomass:
  • In the field of crop production: cereal straw, corn cob
  • In the field of animal husbandry: slurry and manure
  • In the field of horticulture: trimmings of fruit trees and grape vines
  • In the field of food-processing industry: processing by-products
  • In the field of silviculture: logging residues
  • From primary wood industry: sawdust, plane shavings
Biomass raw materials produced for energy production purposes:
  • Woody and herbaceous energy plantations
  • Biodiesel raw materials (rape, sunflower)
  • Bioethanol raw materials (cereals, corn, sugar beet, potato)
Energy production by biomass is carbon neutral, i.e. carbon dioxide released during the combustion does not exceed the amount the plant has used during its photosynthesis.
Thus biomass-based energy production is a viable alternative for the reduction of carbon dioxide, a major cause of the greenhouse effect. It also provides a solution to agricultural overproduction, e.g. only in Hungary approximately half a million tons of surplus firewood is produced annually most of which is exported by the forestry companies at break-even or loss-making price, and which has several other advantages that make it one of the largest potentials of renewable energy source utilization worldwide. 
Characteristics of biomass as energy source:
  • it is renewed through photosynthesis
  • energy storage is realized by storing the energy of the sunshine in the form of chemical energy by the organic compounds created in plants
  • it can be used as an energy source without increasing the carbon dioxide level of the atmosphere
  • it largely facilitates the preservation of mineral resources
  • emission (CO2, CO, SO2, CxHx) is significantly lower than in the case of fossil energy sources
  • lands released due to food overproduction provide realistic basis for biomass production
  • it has a favourable effect on rural development and job creation.
Advantages of using biomass:
  • Decreases Hungary’s dependence on import in respect of energy management (at present, approximately 70% is imported from external sources).
  • Ensures continuous energy production.
  • Decreases environmental pollution (less carbon dioxide emission, decreasing greenhouse effect to meet the commitment assumed under the Kyoto Protocol of the United Nations Framework Convention on Climate Change)
  • Decreases agro-product (food) oversupply. (With the accession to the European Union Hungarian agriculture entered a market with huge oversupply of products. Thus the Common Agricultural Policy may have only one direction: lands being released from agricultural production should be used in a way that will not increase the volume of unmarketable surplus products. One possibility of utilization is producing non-food products, i.e. raw materials for energy production.) 
  • Increases job opportunities for rural residents.
  • Improves environmental conditions.
  • It can be produced anywhere, i.e. it is not bound to deposits.
  • Utilizes agricultural wastes.
  • Its utilization does not require significant investment.
