Biomass is an all-rounder among the regenerative energy sources of the future. While with wind, water and sun just power can normally be created, biomass additionally provides the conversion into heat and fuel.
The technical and energetic effort for the liquefaction of biomass, however, is high and at present the technology is still in the development phase. Thus, today it applies: The easiest way is the most efficient one – the direct burning of woodchippings in a heat coupling plant or in a heating.
Heating plants, which are operated with woodchippings, are CO2-neutral. The carbon dioxide emission, which is released during the incineration process, is identical with the amount of CO2 absorbed during timber growth.
Even under consideration of the forest cultivation, the transport and reconditioning, woodchippings are remarkably more environmentally friendly than fossil energy sources, as the logistics and processing chains are considerably shorter and more efficient.
Turn biomass into a sustainable material – by means of the JENZ product range starting from grinders up to mobile chippers.
Make use of biomass in place.
In contrast to fossil fuels, the use of In contrast to fossil fuels, the use of woodchippings can be influenced with regard to a sustainable energy generation – for example by the exclusive use of the sustainable tree substance of the forests (an average of 7.5 cubic meters of timber per hectare per year) or by the cultivation of fast-growing energy forests.
Normally, especially rural regions dispose of large quantities of biomass and can use woodchippings as heating material. However, they require more storage space than stored energy. Thus, the transport distances should be short and the storage should be effected locally for sustainable and economic logistics.
Systemic efficiency factor
When woodchippings are directly burned, 80 percent of the energy stored in the timber are converted into heat. The efficiency is even higher in a combined cycle of heat and power. Here, electrical energy as well as waste heat are used to a large extent and lead to an efficiency of 90 percent. For comparison, diesel and Otto engines only reach an efficiency of max. 30 percent due to their system functions.
