Biomass as the energy source for critical situations Case Example of the Czech Republic

Biomass is the most important renewable energy source for many of Central and Eastern European countries. National Renewable Action Plans assume biomass share on power generation using renewable energy sources app. 29% and on RES consumption for heating and cooling app. 90% in the year 2020. Biomass as the domestic energy source plays not only important role in RES utilization development, but can also contribute to secure local energy needs in case of critical situations characterized with the failure of energy sources delivery. The Paper presents methodology and the preliminary results of possible biomass contribution to secure energy needs in two kinds of critical situations - temporary failure of energy sources import up to one year, and continually growing deficit of energy sources. The methodology is based on utilization of GIS model used to identify available biomass potential from forestry and from intentionally planted energy biomass on agriculture land taking into account individual time horizons of critical situations. GIS model uses among others information on soil parameters, yields of individual energy crop for given soil parameters, seasonal impacts to biomass potential, individual logistic chains etc.
