Techno Economic Analysis of an Off grid Eco Friendly Flywheel Based Bicycle Generator
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryAccording to the Global Long-Term Climate Risk Index (CRI) 2020 by the German Watch, Pakistan is 5th among 10 countries affected most by climate change. Global warming and scarcity of Conventional resources are becoming major problem in the current scenario. Pakistan’s most of the energy is produced by using conventional sources, but these sources are responsible for pollution and global warming which ultimately result in climate change. That’s why today we need alternative non-conventional sources which are eco-friendly and sustainable. Solar and other renewable sources are several forms of energy which are used alternatively today. One of those sources, Human Power is a lasting source of energy which is wasted during workout. In this FYP project, a prototype modelling of an "OFF-Grid Green Energy Harvesting Flywheel Based Bicycle Generator" which could be used as an "OFF-Grid Battery Charging System" is developed to minimize the lightening load demand of MUET Gymnasium fitness facility. In this mechanism, efficient flywheel energy storage technology is implemented on KERS (Kinetic Energy Recovery System) static workout bicycle generator. Additionally, a relative cost analysis of prototype model, comparative analysis of present with proposed LED luminosity system in terms of CO2 emission, energy unit saving, and its cost saving is analyzed. Feasibility analysis for the implementation of Energy and Climate Change (EC) indicators of Universitas Indonesia Green Metric World University Ranking (UIGM) is also undertake.
Project Objectives- To develop a practical prototype of an "OFF-Grid Green Energy Harvesting Flywheel Based Bicycle Generator" which could be used as an "OFF-Grid Battery Charging System" is developed to minimize the lightening load demand of MUET Gymnasium fitness facility.
- To proposed a techno-economic solution in overcoming the luminosity demand through an inexpensive LED lightening system along with their comparative analysis to the present Tube light luminosity system.
- To investiges a relative cost analysis of prototype model.
- To investigates a comparative analysis of present system with proposed LED luminosity system in terms of CO2 Emission, Energy Unit Saving, and its Cost saving.
- To determine a feasibility analysis for the implementation of Energy and Climate Change (EC) indicators of Universitas Indonesia Green Metric World University Ranking (UIGM) is promote Green Energy sustainability.
- To develop an efficient mechanism for harvesting wasted muscles energy during workout and convert it to clean and green electrical energy.
From Pakistan’s climatic and energy situation point of view, the implementation of this research project has great scope.
- The benefits of this project will be very helpful in overcoming the luminosity demand of gymnasium through an efficient LED lighting.
- It could be a techno-economic solution to lower the overall Green House Gas(GHG) Emission.
- It could be a techno-economic solution to lower the overall Energy Consumption annually.
- It could be a techno-economic solution to lower the overall Energy Consumption Cost of Mehran University of Engineering & Technology(MUET) annually.
- It will promotes Green Energy sustainability.
- It will promotes self energy sufficient green Gymnasium phenomena.
- It will help in the implementation of Energy and Climate Change (EC) indicators of Universitas Indonesia Green Metric World University Ranking (UIGM).
- It will help MUET to impove their Global Ranking in terms of Climate and Green Energy sustainability.
a) Calculation Formulas for Energy Saving Energy Saving
C = A - B…………. eq (1)
Where,
A= (1st session operating hours × Sum of 60 W connected load operates in 1st session) + (2ND session operating hours × Sum of 60 W connected load operates in 2ND session) ……eq (2)
B= (1st session operating hours × Sum of 6 W connected load operates in 1st session) + (2ND session operating hours × Sum of 6 W connected load operates in 2ND session) ……eq (3).
b) Calculation Formula for Cost Saving Cost Saving
D = C (Energy Unit Saving, daily/weekly/monthly/annually) × (Cost/Price of Single Unit of Energy) ………. eq (4)
c) Calculation Formulas for Co2 Emission Saving
Primary electricity production in Pakistan from thermal (oil, natural gas, etc.)
- 1KWH= 0.001 MWH
Since,
Energy produce in this proposed “Off-Grid Eco-Friendly bicycle generator” is 100% green.
So, there is no Co2 emission.
Therefore, the amount of Co2 Emission saving through proposed idea as compare to 60 W tube light system is given by the formula as:
CO2 Emission Saving = (Energy Consume while 60 W system operational in KWH) × (CO2 Emission Factor for solar, wind or other sources) × (0.001 MWH/KWH)
CO2 Factor for wind and solar is 0.600ton Co2 per Megawatt hours.
While its value for other source is 0.501ton Co2 per Megawatt hours according to the Asian Development Bank.
