    Achtung: AM 25.10.2021 findet eine Exkursion statt!!! Meeting at Niedersachsendamm, above the dock,+Oldenburg/@53.1262688,8.2115821,17z/data=!4m5!3m4!1s0x47b6df740222db2d:0x48fecacd18891a99!8m2!3d53.1263396!4d8.2136742 Lecture Goal and Competencies: The lecture Hydro Power I seeks to familiarize students with technological, socioeconomic and ecological aspects. Students get acquainted with basics of the technical components of Hydro Power (HP) and Ocean Power (OP) systems: their setup, their operation, their specific challenges and their linkages with one another. At the end of this unit students may size a HP for given local geographic and hydrological conditions on a basic level. They can describe the entire setup as well as individual components. They are aware of basic challenges beyond the technical problems of HP and OP systems. Students are in the position to list advantages and disadvantages of HP and OP in comparison with other renewable energy technology. Detailed Content*: • 2h Theoretical background – general hydraulic terms, Bernoulli Equation, Major Empirical Formulae and their backgrounds. • 2h Water Resource – catchment area, seasonal precipitation, flow duration curve, dam, & run off river. • 2h Powerhouse – penstock, water hammer, cavitation, tailrace. • 4h Turbines – main types of turbines, their characteristics & their components. • 3h Ocean Power Overview * indicated times are face-to-face times.

    The students will understand the principles and potential uses for biomass as well as the shortcomings of biomass as a renewable energy. The students will develop an understanding of the growth and degradation of every type of biomass, as well as the basics of a balanced ecosystem and the sustainable use of biomass. Students gain basic understanding on biomass processing technologies. In cooperation with the Energy Systems & Society Module, one shall gain an understanding of the connection between man and the function of a healthy ecosystem and its preservation. Competence: The students gain competencies with critical discourse of competitive uses of biomass between human consumption, animal feed, raw material and fuel. The students are taught the issues concerning biomass transportation as well as the economic and ecological criteria involving its planning and use. They develop criteria, in order to address the complex relation between the future and a sustainable energy supply. The students gain competence to better the living conditions of rural inhabitants in developing countries through improved applications of biomass for daily energy needs. Content: Basic Understanding of: • Nature or photosynthesis: chemical storage of solar energy; Efficiency of Plants • Composition of biomass: sugar, starch, fat, oils, protein, lignin • Knowledge of typical crop yield and energy content of various plants • Typical energy crops in different climates • Form and distribution of biomass uses in different geographic and climatic regions • Traditional and modern energetic uses of biomass as well as the efficiency and technology • Degradation process of biomass: Microorganisms, classification and metabolism (main degradation) Sustainable Biomass Use • Soil fertility, decrease and destruction of natural fertility • Soil ecology • Growth and diversity of biomass • Roll of the microorganism in the metabolic cycle Technology The guiding theme are the principles of traditional and modern energetic use of biomass, the constraints and efficiencies for food preparation, transport, and thermal and electrical energy production • Biomass cookers, Improved Cook Stoves • Wood gasification • Biogas equipment • Biodiesel production • Ethanol production from sugarcane • Methanol production

Notes for the module
Reference text

Within the lecture Hydro and Marine Power an excursion to a hydropower plant and the catchment area will be offered. The duration of this excursion will be in total 5 hours.

It is recommended to know the basics of photosynthesis.

Skills to be acquired in this module

After the completion of the module students should be able to

-       critically evaluate and compare two Renewable Energy conversion processes which allow
         continuous power supply on demand (hydropower and biomass energy)

-       confront those systems to a Renewable Energy conversion process with intermittent output
        (marine power)

-       discuss extreme situations in Renewable Energy systems’ source and transfer such situations
        to other Renewable Energy systems

-       analyse various system components and their interconnections within a complex Renewable
        Energy supply system,

-       evaluate the Renewable Energy supply systems’ operational size and efficiency,

-       critically evaluate non-technical impact and side effects when implementing renewable
        energy supply systems

-      understand the basic chemical background of bioenergy-related materials, systems and
