Campus Lyngby
Undervisningsform:
Two weeks of lectures, exercises, and assignment work. 60 hours
of reading (articles, book chapters, documentation and technical
documents), and submission of a written assignment.
Energy production is responsible for a considerable share of the
environmental impacts today. Significant efforts are carried out to
develop new and more efficient energy technologies in order to
minimize the environmental loads. In order to quantify these
benefits, however, the environmental consequences should be
assessed in a systematic and consistent way. This course provides
students with the necessary expertise to perform state-of-the-art
life cycle assessment (LCA) of (bio)energy technologies as well as
entire energy systems. Through the course, students learn to use
the advanced LCA model EASETECH on energy technologies and
systems.
Læringsmål:
En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:
Be familiar with life cycle assessment (LCA) principles
Apply LCA assessment principles to energy technologies and
systems
Define material, substance and energy flows for individual
bioconversion technologies and scenarios
Define LCA modelling scenarios for individual bioconversion
technologies and integrate these into combined biorefinery
systems
Define LCA modelling scenarios for entire energy systems
involving a variety of individual (bio)energy technologies
Evaluate the importance of biomass composition,
land-use-changes, alternative uses of biomass, and uncertainties
for the LCA results
Analyze individual (bio)energy technologies as well as
integrated energy systems with the EASETECH LCA model software
Interpret and communicate LCA results
Kursusindhold:
The course is targeted to PhD students who aim to apply life cycle
assessment to specific bioconversion technologies or pathways for
systematic evaluation of their environmental performances. The
course includes an introduction to LCA modelling of energy
technologies and energy systems as well as exercises involving
building and assessing an integrated biorefinery concept with the
LCA-software EASETECH. Introductory lectures are provided in
relation to: LCA principles, biomass conversion technologies (e.g.
thermal, ethanol, diesel, gas), biomass generation and composition,
alternative uses of biomass, land-use-changes, management of
residuals (e.g. use-on-land, combustion),
material/substance/energy flow analysis, life cycle inventory
data, data uncertainties, and interpretation of results. Students
apply the introduced concepts in a range of exercises leading to a
full LCA scenario of an integrated biorefinery system. Challenges
when performing LCA of energy systems with highly intermittent
production are also addressed. After the course, an extended
abstract is submitted summarizing the LCA modelling of a selected
system (e.g. the biorefinery system from the exercises).
