2 The source of decentralized bioenergy centres Sun Wind Plants vegetation Solar cell Solar collector Wind generator Biomass Solid Fermentable Wood gas Biogas Other combustion fermentation products Electric energy Heat energy Electric energy Mechanic energy Continuous Non-continuous Agricultural land Employment /new jobs

3 Is there future of agricultural land (soil)? Biomass transformed into solar energy 1 kg of biomass is made from 11,849 MJ solar power Artificial synthesis: from methane 80% carbohydrates, 10% protein, 10% fat components 1086 MJ energy required Energy demand is 100 x fold compared to natural way (photosynthesis) Conclusion: photosynthesis/biomass is the best way of storing (changing form one form to the other) energy

4 Biomass degradation Composting Aerob circumstances Biogas production Anaerob circumstances Carbon balance Approx. 50% built into Approx. 5% built into biomass, biomass, 50% goes to CO 2 95% goes to biogas Energy balance Approx. 60% used up Approx. 90% stored for new cell growing in biogas, 40% waste heat 5-7% cell growing, 3-5% waste heat

5 What is biogas? Organic material anaerob in (oxigen free) space fermented into a gas. Components (endproducts of fermentation) are different depending on used raw material.

6 The general components of biogas: Methane: 50-65% CO 2: 30-35% Other gases (H 2 S, CO, N 2) : 1-2%

7 Open-system cultivation Products Byproducts -Storage -Processing Marketing Nutrient purchase Market

8 Sustainable plant growing (1) Food Fuel Animal food Litter Organic nutriens manure Composting Manure Waste, wood ash

9 Sustainable plant growing (2) Food production Biogas plant Raw materials Biogas plant - Silage - Sugarbeet - Green waste - Energy crops - Luzerne - Sweet sorghum Bio fertiliser Other, biogas -Restaurant waste -Sewage-sludge -Communal green waste -Slurry with litter -Food industrial waste

10 Biogas energy efficiency

11 Biogas plants in Germany Number of plants in Germany

12 Decentralized bioenergy

13 Bioenergetikai központra telepíthető tevékenységek Industrial works as energy users Industrial works, onto utilization of industrial stocks Biovegetable, fruits producing greenhouses (In these happens the heat, the bio fertilise and CO 2 using) Cold storage plant, in which the produced produces are processable cheaply, (the cold storage plants with heat and the biogas motors they work with the thermal energy of his exhausts) Raw material product for biogas plant(a végén képződő biotrágya itt kerülhet felhasználásra) Drying of plants and fruits with biogas-heat Opportunity to work tractors and cars with biogas and bioethanol

14 Complete use of waste heat energy Activities Months Ethanol distillation Vegetable growing Bio mushroom growing Heating Bio mushroom growing Cooling Storage (cooling) vegetables/fruits Drying medical herbs /animal feed plants

17 ENVIRONMENTAL ASPECTS? Side effects: m3 natural gas energy heat output -50 hectare agricultural land regenerated nutrition cycle -50 hectare land long term bio-fertilising Power output: 1000 families annual electricity need 50 hectare agricultural land (150 kwe Hochreiter biogas plant) - 2 full time job for 15 years -Other potential effects: - e.g. waste heat usage rural industry, healthy food from bio digestate,
