Module summaryThis module will give a detailed description of the CO2 reduction technology for climate change mitigation through improved thermal efficiency in NG fired CCGT for electric power generation and reduced transport fuel consumption The technology of renewable biofuels and hydrogen, for transport is also discussed. The role of electricity for transport and the related issue of the CO2 of electric supply. Transport legislated air pollution emissions control includes the latest technology for NOx and PM control.
Objectives- To study transport policy options for low CO2 from transport including electric vehicles, hybrid vehicles and the possible use of hydrogen in SI engines and fuel cells.
- To understand why real world road transport emissions and fuel consumption (RDE) are higher than for legislated test cycles.
- To understand the factors that influence carbon emissions from transport and the technologies to improve the thermal efficiency of SI engines and the reasons why diesel engines are superior from a carbon audit viewpoint.
- To understand why lean burn SI and diesel engines have a superior thermal efficiency than at SI at lambda=1 and why the control of NOx and particulate emissions is so difficult.
- To understand the control of CO, HC, NOx and particulate emissions from SI and diesel engines and the conflict of meeting the legislation for these pollutants as well as minimising carbon emissions.
- To study carbon reduction techniques from electric power generation using combined cycle gas turbines and the options for CCS applied to gas turbines.
- Knowledge of how to minimise carbon emissions from transport engines and power generation gas turbines with an ability to advise on how carbon emissions can be reduced.
- Detailed knowledge of the climate change contribution of road transport and the difficulties of using alternative fuels in this sector, with a real overall carbon reduction.
- Knowledge of the principles of well to wheels CO2 analysis and carbon audits.
- Knowledge of how to reduce CO2 emissions from transport and why lean burn diesel and gasoline engines are necessary.
- Knowledge of the methods of NOx, CO, HC and particulate control in SI and diesel engines and their conflict with CO2 reduction.
- Knowledge of climate change issues and the role of transport and the complexities and possibilities of meeting the target for 80% carbon reductions from transport and electric power generation by 2050. Knowledge of policy options to achieve carbon reductions in these areas.

|Private study hours||106.00|
|Total Contact hours||44.00|
|Total hours (100hr per 10 credits)||150.00|
Private studyStudents are given comprehensive notes and are expected to study for at least one hour for every hour of lecture in preparation for the exam and to understand the material - 44 hours minimum study of lecture material. Not all the notes are covered in class and some are expected to be read as part of private study.
The coursework is 40% of the module and is expected to take 40% of the module time which is 60 hours. This brings the total hours to 148 and the exam is the last two hours, giving the total workload of 150 hours.
Opportunities for Formative FeedbackAttendance at the four teaching activities each week.
Submission of coursework.
