3 1. BASICS of Bioenergy in Agriculture

4 Biogas Electricity Overproduction Wind GAS H2 CO2 CH4 BIOGAS (55 % CH4) Sale and Trading BIOMETHANE (98 % CH4) Biogas - Plant Gas Grid Electricity Heat Raw Material Organic Fertilizer Fuel / Transport Material Use Biomass Production Logistic Production of raw biogas Upgrading Injection Application Source:

5 Biogas

6 Solid Biomass Forestry wood Waste wood Wood from short rotation coppice Log wood pellets Wood chips Straw Sources: Eviva

7 Solid Biomass

8 First generation biofuels Biofuels Second generation biofuels Third generation biofuels Production directly from food crops Produced from non-feedstocks Produced from algae Ethanol, Biodiesel, Vegetable oil

9 Biofuels Vegetable Oils Lower Heating Value (LHV): ~ 37 MJ/kg = 10,3 kwh/kg (~90% diesel) Resources: vegetable oil seeds: rapeseed, oil palm, sunflower, soy beans Biodiesel LHV: ~ 37 MJ/kg = 10,3 kwh/kg (~90% diesel) Vegetable oils (fresh or used), grease, tallow Bioethanol Biogas LHV: ~ 27 MJ/kg = 7,5 kwh/kg (~65% gasoline) Sugar or starch crops: sugar cane, sugar beet, wheat, corn LHV: ~ MJ/m 3 = 5,5 6,1 kwh/m³ (~55-65% natural gas) Digestable biomass: organic residues, manure, agricultural residues, corn silage etc.

16 Advantages and Disadvantages of Biofuels vs Fossils Advantages Higher energy efficiency Lower fuel price Lower SO 2 emissions Lower GHG-Emissions assuming adequate cultivation and oil production methods Better emission levels (PM 10, CO) if engines are properly modified Higher maintenance requirements (injectors, pumps) Disadvantages Engine modification necessary Quality issues Bad Viscosity at low temperatures Higher fuel consumption (the lower heating value of vegetable oil equals to ~90% compared to diesel) Slightly loss of power of the engine Hazard of damages by improper maintenance (lube oil changes) Higher corrosion and engine deterioration when using low quality oils Source:

25 Use of Algae for CO 2 - Compensation

26 5. Good Practice Examples

27 Example Biogas: BGP Bremker Owner: Private Substrates: Kitchen waste, Residues, Green Wastes Storage Capacity: 1 hours 1 Gasmotors Power Capacity: 75 kw el. Heating of public school and private Homes Source:

28 Economic use of waste materials in agriculture Example Straw: Krone Premos Pelletizer Substrates: Straw Power required: 350 kw + Net Energy Required: 5 %

29 Economic use of waste materials in agriculture Example Biofuel: Waste / Used Oil Owner: Private and Commercial Substrates: Fat / Cooking oil Application: Cars, Trains, Buses

30 6. Summary

31 - Bioenergy Production for multipurpose energy use - Bioenergy offers economic, social and environmental benefits for rural areas. - Bioenergy offers interesting and qualified job opportunities - Bioenergy have great potential in future energy systems - energy balancing.

32 - Planning a modern and safe Bioenergy - plant requires a lot of experience especially economic operation is an important issue! - For safe operation and low maintenance rigourous planning,construction management and staff training is necessary. - Bioenergy - Plants can provide cheap electricity and heating with local raw materials combined with low transportation expenses.
