Investigate the Possible use of Hybrid Solar and Wind Energy Power Supply for Local Recreational Boat

Abstract

The Fuel Economy Has Been One Of The Dominant Issues In The Transportation Sector. Combustion Engines In Boats Bring Several Environmental Problems, Such As Greenhouse Gas Emissions And Acidification Of Oceans. Air And Water Pollution Is Rapidly Increasing And Affecting Most Of The Major Cities Of The World. In Addition To That Developing Country Like Ethiopia Has A Great Scarcity Of Oil Fuel. To Address These Issues The Combined Utilization Of Renewable Energy Sources Is Becoming Increasingly Attractive And Is Being Widely Used As Alternative Sources Of Energy. The Main Aim Of This Thesis Work To Investigate The Possible Use Of Hybrid Solar And Wind Energy Power Supply For Recreational Boats Manufactured Locally. To Achieve The Objectives Of This Thesis The Data About Solar Radiation And Wind Speed Was Gathered From The Ethiopian Meteorological Agency. For The Numerical Analysis, The Boat Was Modeled In Catia V5 And The Cfd Analysis Is Carried Out In Ansys Fluent. The Simulations Were Based On The Reynolds Average Navier-Stokes Equations With Sst K-?? As Turbulence Model Together With The Volume Of A Fluid Method Describing The Two-Phased Flow Of Both Water And Air Surrounding The Boat. In Addition To This Ansys Hydrodynamic Was Done For Testing The Stability Of The Boat. Moreover, The Model Was Also Constructed For Demonstration Purposes. The Propulsion Power Was Determined As 5hp. The Average Energy Output From The Solar System Is 6.66 Kwh In February And The Average Energy Obtained From The Wind Turbines Was 1.3 Kwh In May. However, The Energy Produced By The Integration Is Insufficient To Run The Boat, As A Result, It Was Concluded To Propel The Boat By Integrating Solar Energy With A Grid System That Uses Energy Stored In Batteries. This Produces The Required 20 Kwh Power Used To Drive The Boat. Besides The Results Of The Hydrostatic And Hydrodynamics Stability Testing Confirms The Stability Hence The Metacenter Height Of The Designed Boat Is More Than The Recommended (0.75m). The Life Cycle Cost Of The Proposed Pv Solar System And Electric Grid System Is 847,726.65 Birr Which Is Low Compared To Gasoline, Which Its Life Cycle Cost Is 3,500,160 Birr. Finally, The Testing Of The Constructed Model Was Functional And Shows A More Stable Condition When The Keel Is Installed.
