What are the primary vehicle emissions

Reference no: EM132650954

Task Sheet

Client Brief

You are employed by the Silver Coast City Council in their transportation sector. The Council has recently set a target of supporting the uptake of electric vehicles to achieve a total of 10% of the total vehicle population by 2040.

You are upgrading a 10 km section of major highway in your region and investigating infrastructure that may help support the increasing number of electric vehicles. Your task is to write a Project Specification for an on-road vehicle charging grid that allows the anticipated electric vehicles load to have the same range (in km) as a petrol vehicle on this section of road. Your project specification must include guidelines for the number of electric vehicles that need to be supported, as well as anticipated savings in CO2 emissions from the implementation of such a system.

The Council has available the following datasets which should be used to help prepare your project specification.
• Average daily traffic for the highway in the year of 2020
• Growth rate for daily traffic volumes (per annum)
• Percentage (%) of heavy vehicles
• Current Percentage (%) of electric vehicles
• Climate data
The design life for the project is 20 years.

Task A: Evaluation of Client Brief
Evaluate the Client brief provided:
• identify any assumptions that have been made by the client. Are these assumptions justified? Are there any assumptions that need to be investigated more rigorously?
• Identify any bias in the client brief.
• Identify the core underlying problem which the possible solutions must address.

Task B: Preliminary Research Task
• What are the primary vehicle emissions produced by petrol and diesel engines? What kind of damage do these do to the environment?
• What are the advantages and disadvantages of electric vehicles?
• Is the goal uptake of electric vehicles provided by the Council (10% by 2040) reasonable according to
other forecasts provided in Australia? Is this uptake likely to be linear as suggested by the Council?
• What sort of infrastructure currently exists for on-road recharging of electric vehicles in Australia and Internationally? Where has this infrastructure been used successfully? Identify the advantages and disadvantages? (Hint: research microgrids for charging electric vehicles).
• What sort of sustainable options are available for providing power to on-road recharging grids? What are the advantages and disadvantages of these options as opposed to a connection to the main power grid?
n What sort of climate conditions might be required for the sustainable options discussed above?

Task C: Data Analysis

Evaluating Carbon Savings
• Using the traffic count data provided calculate the daily traffic volumes per year from 2020 to 2040. v/
• Using the traffic count data provided calculate the daily number of passenger vehicles and heavy vehicles per year from 2020 to 2040. /
• Using the traffic count data provided calculate the number of electric vehicles per year from 2020 to 2040. Assume that the uptake of electric vehicles increases linearly to 10% in 2040. 1. t 10'1 -5, is
• Calculate the greenhouse gas emissions produced by the vehicles for each year assuming no increase
in the uptake of electrical vehicles on the highway. (Hint: The number of electric vehicles remains at 2%).
• Calculate the greenhouse gas emissions / km for each year assuming a 10% uptake of electric vehicles on the highway by 2040.
• Calculate the reduction in greenhouse gas emissions per year due to the increase in the use of electric vehicles. Plot these values on a bar chart.

Evaluating Energy Demand
Preliminary modelling has been done by the Council and has determined that 10kW of power must be transferred per electric vehicle to allow for the required extension in vehicle range.
• Calculate the total daily energy required for years 2020 2025 2030 and 2035 and 2040. Plot these values on a bar chart.

Evaluating Climate Data
The ability to supply the energy demand of the grid using solar power varies throughout the year depending
on the solar irradiance of the site (kWh/m2/day). The average monthly irradiance at a location close to the site
has been measured over a 20- year time period and is included in the climate data in the attached
spreadsheet.
Calculate the following statistical values for each month, (January to December),
• Mean
• Minimum
n Maximum
n Standard Deviation
Task C.3. Assessing Size of Solar Panels and Storage Capacity
The average daily power that can be generated from the solar panels can be calculated using the following equations
• What is the minimum total area for the solar panels to supply the required demand? Assume a solar array efficiency of 20%.
• Is it likely this this energy demand can be entirely supported through solar power? If not, what proportion would you recommend is powered using solar. What other alternative power solutions should be considered?
• Based on your research and the daily energy requirements recommend a storage capacity for the system.
Task C.5. Limitations of Analysis
Discuss what the limitations of this analysis are. Identify what assumptions underpin the accuracy of your predictions.

Task D: Develop the Project Specification
Develop a project specification for the problem. Your Project Specification should comprise of the following:

Task D.1. Summary problem statement
• Use the information you have collected and analysed to provide a succinct statement of the scope of the project (This task should be revisited once you have completed your project specification to ensure that you have a clear understanding of the problem.)

Task D.2. Qualitative Project Goals
• Identify at least four (4) qualitative project goals. Your project goals will describe the key
characteristics that will be delivered by the project. Remember that you are not looking for solutions but the qualities that would define a successful solution. A goal describes the ultimate desired state that the final solution will achieve. It is broad and generalised. Dowling (p504 3'd end; p432 2nd edn) may provide you with some further ideas.

Task D.3. Quantitative Project Objectives
• Develop a list of objectives that the project will need to meet. These objectives will form the basis of an Evaluation Strategy.
There should be a clear mapping (relationship) between the project goals and the project objectives. You should attempt to quantify your project objectives using information from your data analysis. For objectives that you do not have sufficient information to quantify them - identify what additional information would be needed.
Your project objectives should be SMART (specific, measurable, attainable, realistic, and timely).
D.4. Project Assumptions
• Document the key assumptions which have been identified during the client brief analysis and data analysis.
D.5. Project Constraints

• Identify any constraints that apply.
• Identify where further information would need to be provided by the Client or further studies undertaken to quantify these constraints.
