MAS531 Bio- and E-fuels
Course description for academic year 2022/2023
Contents and structure
Reducing emissions is one of the biggest challenges for the transport and energy sector, however, there are both benefits and challenges associated with the transition to alternative fuels.
Different applications place different, application-specific demands on energy carriers, and this can affect the operating result for a given application. The transition to new types of bio- or alternative fuels presents challenges that must be understood to avoid problems in operation. Knowledge of system solutions for supply and pre-treatment of fuel(s) will be important for the design of reliable and efficient future installations.
The course provides an overview of how alternative fuels are produced in terms of power requirement, costs, storage and logistics and how to compare these in different applications. The specific properties of synthetic fuels, how they can be analysed and which consequences result from introduction of these to energy systems already in use, will also be covered.
Subjects:
- Focus on the following alternative energy carriers: Biogas, biodiesel, methanol, hydrogen, ammonia
- Operation and use-related properties of the most relevant alternative energy carriers
- Different processes for the production of bio- and synthetic fuels
- Power-to-X processes and technologies for the production of various energy carriers
- Well-to-tank analysis for different energy carriers
The course touches upon the following UN Sustainability Goals:
- #7: Affordable and clean energy for all
- #9: Industry, innovation and infrastructure
- #13: Climate action
Learning Outcome

Entry requirements
The study programme’s entry requirements
Recommended previous knowledge
Knowledge in Thermodynamics, Chemistry and Heat conduction
Teaching methods
Lecture, field trips, group work, discussions, assignments, presentation.
Compulsory learning activities
All students shall present one submission of their portfolio.
It is mandatory
- to attend the presentation day
- to give a presentation of one written submission
Assessment
Part 1: Portfolio assessment, accounting for 60% of the final grade
The learning portfolio consists of submissions related to the following topics: production technologies and processes; gaseous fuels; liquid fuels; carbon-free energy carriers; ''Well-to-wake'' analysis
The assessment portfolio has to consist of 3 submissions from the learning portfolio. The students have to choose themselves which submissions are to be included.
Part 2: Oral exam, accounting for 40% of the final grade
Both parts of the exam must be passed to get a grade in the course. If you do not pass one of the parts, the part can be taken up again alone.
Grade scale A - F, with F being not passed.
Examination support material
Portfolio - not restricted
Oral exam - none
