Lecture Energy in agriculture regrowing natural resources

Contents: Fundamentals: Basic physics, Energy management, CHP-systems, Feed-in Technology, Heat conversion and recovery, Design of priority circuits Need for the use of biomass for energy: Energy scenario and potentials, Emission of climate changing gases, Sources of energy from biomass, non biomass and waste material, Selecting and processing biomass as a fuel: Biogas. Fermentation process and plant technology, Vegetable oil. Processing of vegetable oil from different origins, Modifications on internal combustion engines for the use of native oils , Biodiesel. Processing of alcohol esters from triglycerides and FFAs, Ethanol. Fermentation process, distillation and dehydration, Thermo-chemical processes. Gasification, Fischer-Tropsch-Process Renewable non biomass energy: Wind. Electric energy and water lifting, Water. Design and potential of hydro power plants, Solar. Solar thermal collectors and photovoltaic Principles of a sustainable plant production for industrial purposes. Crop management for protein, starch, fibre, sugar, fuel, electricity and heat production with respect to the quality of products and the demands of industrial processes. Objectives: Based on the related data and basic physics, students are able to identify and calculate potentials and limits of energy production from renewable primary products, solar, wind and water sources. Students know the relationships between product quality and quantity and climatic/edaphic factors and management means and they are able to plan the adaptation of production processes to achieve a given target value in product quality.
