CPE337/332/6300 Introduction to Fuels and Energy -Assignment
Introduction to Fuels & Energy
Assignment

Problem Statement

Your are carrying out two tasks for the Department for Energy and Climate Change in the Governmentof the country you have been allocated.

Task 1: (Part A)

Produce a report to brief the government on the current energy demands for electricity, heat andtransport based on the data available on IEA for that country. (If you use information from othersources, please verify the reliability of the sources and reference the sources).

Task 2: (Part B)

Identify a sensible mix of zero carbon energy sources to meet the demands and decarbonize theeconomy by 2050.

Country Allocation and Energy Data

You can self-enroll a country and you will find the information in the folder for assignment. Select theappropriate energy data from IEA – International Energy Agency . Note the units and numerical number of the final energy consumptions appear when you navigate your computer mouse on the diagrams.
Data for Heat could appear in data for energy consumptions in industrial and residential.

Assignment Submission Requirements

Task 1: Part A Report (maximum 3 pages including references, count to 15% of module assessment )

You should produce an individual report, and submit the report through the BB link for Part A. The deadline for the Part A report is 18th November 2024,23.00pm. We are aimed at giving you some feedbacks on 12th December 2024.

• A summary on the current energy demands for electricity, heat and transport based on theIEA diagrams for that country. 60%
• An overview of key energy resources in that country. Identify any underutilized renewableenergy sources. 30%
• Any initial thoughts on your strategy for decarbonizing electricity, heat and transport. 10%

Task 2: Part B Report (maximum 3 pages including references, count to 15% module assessment)

You should produce an individual report, and submit the report through the BB link for Part B. Thedeadline for the Part B report is 20th January 2025,23.00pm

1. Your strategy for decarbonizing electricity, heat and transport. 30%

• Select one sector from electricity, heat or transport.

• Use the energy demands you have determined in Part A

Electricity sector: CPE337/332/6300 Introduction to Fuels and Energy -Assignment you don’t need to consider extra electricity needed as the results of the recommendations from heat or transport sectors.

Heat Sector:
If you recommend electrification of heat, you should consider what the extra electricity is needed and how to generate the extra electricity.
Transport Sector:

If you recommend electric vehicles, you should consider what the extra electricity isneeded and how to generate the extra electricity.

If you recommend hydrogen powered vehicles, you should consider how hydrogen is produced.
2. Quantify the capacity of each key technology proposed. 40%
3. The land/sea area required for the technologies (and associated planting if biomass/biofuel) and consideration as to the feasibility of this (e.g. percentage ,of available areas). 10%
4. Your expectations in regard to the need for energy storage and the appropriate types (this does not need to be detailed) 10%
5. Include any other points you think are important or country specific issues that maypresent challenges, including any benefits that might arise to the country as a result ofthe transition. 10%

Assumptions

  • You do not need to allow for any growth in energy demands in your country (use 2023 IEA data, or use the most updated data as the basis for your analysis), but you mustappropriately allow for changes in primary energy requirements arising from  your choices.
  • Your technology choices should be appropriate to the selected country and where possible you should use data sources appropriate to that country to determine the performance of your decarbonization options. If this is not available, you may use information presented in lectures or from the web with suitable references.
  • You do not need to determine the volume or cost of energy storage required by your combination of technologies. However, you should endeavor to select technologies that mitigate the need for long duration storage (these will depend on your country selection) and indicate the types of storage that you think might still be required.
  • If you choose to use hydrogen as an alternative fuel/storage medium, you should assume that electrolysers operate with an average efficiency of 65% and fuel cells, an efficiency of 50%.
  • For transport, you may assume that the final energy consumption stated in the IEA data can be split as follows with alternative system efficiencies:


% of final transport  energy
Fossil fuel /biofuel Efficiency
Elec/Battery - to-wheel efficiency
Hydrogen - to-wheel efficiency
Rail
 As in IEA
 35%
 85%
 50%
Heavy Road Freight 
 30% of ‘Road’
 30%
Bus Transport
 10%  of ‘Road’
 20%
Light Duty Vehicles
 60% of ‘Road’
 25%

If you believe that there is scope to encourage mode shifting of transport (e.g. more freight to rail, or car to public transport), then you should indicate this and suggest policies to deliver it. You should calculate changes in energy from mode shifts based simply on % of each mode that you think can be changed.

  • For heat, assume that all non-electricity industry use is for heat > 100°C, and that all nonelectricity ‘Other’ use is for low grade heat @ < 60°C.
    • Domestic heat pumps: CoP = 3.0*
    • Large Scale Heat Pumps: CoP = 5.0*
    • Combined heat and power: assume an overall seasonal efficiency (includingelectricity production) of 75%. Use information from lectures for electrical component. (e.g. a fuel cell will operate with an electrical efficiency of 50% and heat efficiency of 25% with 25% losses)
    • Boiler systems, regardless of fuel, assume 85% efficiency 
  • For land area estimates use data from lecture slides or referenced sources (fuel cells and bio-fuelled power plant can be assumed to have negligible land area except for that required to grow biomass).
  • You may ignore any non-energy uses on the IEA diagrams.

*Coefficient of Performance (COP) of Heat Pumps

In the case of a heat pump, its efficiency is the ratio of useful heat energy produced to electrical energyconsumption. A COP of 3 means that the heat pump  supplies 3 times as much heat energy to thesystem as it consumes in electrical energy.
