Abstract

The biogas generated in biogas plants offers significant potential for the production of energy from renewable energy sources. The number biogas plants in the Czech Republic is expected to exceed one hundred in the near future. Substrates from agriculture, industry and municipal wastes are used for biogas production. Biogas plants usually use co-generation units to generate electricity and heat. Increased effectiveness can be achieved by using heat as a source of energy for producing renewable natural gas.

Highlights

  • Biogas plants are significant sources of renewable energy

  • The technology is suitable for villages and towns that can efficiently handle the processing of separated biologically degradable municipal wastes by means of suitably located biogas plants, leading to less waste disposal in landfills

  • The construction of biogas plants can reduce dependence on fossil fuel imports, and it is in accordance with the commitment of the Czech Republic toward the EU to increase the proportion of energy produced from renewable resources

Summary

Introduction

Biogas plants are significant sources of renewable energy. There are 47 such facilities in operation in the Czech Republic, and in 2008 they produced 214 GWh of electric energy (0.3 % of total consumption). Biogas production from various kinds of degradable substrates in biogas plants is technically feasible and economically viable. This resource offers considerable potential, and with complete utilization the capacity is in excess of one thousand MW. The construction of biogas plants can reduce dependence on fossil fuel imports, and it is in accordance with the commitment of the Czech Republic toward the EU to increase the proportion of energy produced from renewable resources. There could be a total of several hundred biogas plants in the Czech Republic within the 20 years
