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 Government
of the country you have been allocated.
Task 1:
Produce a report to brief the government on the current energy demands for electricity, heat and
transport based on the IEA Sankey diagram for that country.
Task 2:
Identify a sensible mix of zero carbon energy sources to meet the demands and decarbonize the
economy by 2050.
Country Allocation and Energy Data
You will be allocated a country and you will find the information in the folder for assignment. Select
the appropriate energy data from
Sankey diagram and that the diagram can show either energy balances or final demand (selected below
the country). You should be able to make reasonably informed decisions about how each of these
energy streams is used in your allocated country from these diagrams.
Assignment Submission Requirements
Task 1: Part A Report (maximum 4 pages, 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 13/11/23, 23.00pm. We are aimed at giving you some feedbacks on
4th December 2023.
• A summary on the current energy demands for electricity, heat and transport based on the
IEA Sankey diagram for that country.
• An overview of key energy resources in that country.
• Any initial thoughts on your strategy for decarbonizing electricity, heat and transport.
Task 2: Part B Report (maximum 4 pages, count to 15% module assessment)
You should produce an individual report, and submit the report through the BB link for Part B. The
deadline for the Part B report is 15/01/24, 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:
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.
CPE337/332/6300 Introduction to Fuels and Energy -Assignment
Transport Sector:
If you recommend electric vehicles, you should consider what the extra electricity is
needed and how to generate the extra electricity.
If you recommend hydrogen powered vehicles, you should consider how hydrogen is
produced.
2. 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 may
present challenges, including any benefits that might arise to the country as a result of
the transition.

Assumptions
• You do not need to allow for any growth in energy demands in your country (use 2018 IEA
data for pre-pandemic data, or use the most updated data as the basis for your analysis),
but you must appropriately 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 Sankey 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
CPE337/332/6300 Introduction to Fuels and Energy -Assignment
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 non-
electricity ‘Other’ use is for low grade heat @ < 60°C.
o Domestic heat pumps: CoP = 3.0
o Large Scale Heat Pumps: CoP = 5.0
o Combined heat and power: assume an overall seasonal efficiency (including
electricity 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)
o 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 Sankey diagram.
