151-0928-00LCO2 Capture and Storage and the Industry of Carbon-Based ResourcesW4 KP3GM. Mazzotti, A. Bardow, P. Eckle, N. Gruber, M. Repmann, T. Schmidt, D. Sutter
KurzbeschreibungCarbon-based resources (coal, oil, gas): origin, production, processing, resource economics. Climate change: science, policies. CCS systems: CO2 capture in power/industrial plants, CO2 transport and storage. Besides technical details, economical, legal and societal aspects are considered (e.g. electricity markets, barriers to deployment).
LernzielThe goal of the lecture is to introduce carbon dioxide capture and storage (CCS) systems, the technical solutions developed so far and the current research questions. This is done in the context of the origin, production, processing and economics of carbon-based resources, and of climate change issues. After this course, students are familiar with important technical and non-technical issues related to use of carbon resources, climate change, and CCS as a transitional mitigation measure.

The class will be structured in 2 hours of lecture and one hour of exercises/discussion. At the end of the semester a group project is planned.
InhaltBoth the Swiss and the European energy system face a number of significant challenges over the coming decades. The major concerns are the security and economy of energy supply and the reduction of greenhouse gas emissions. Fossil fuels will continue to satisfy the largest part of the energy demand in the medium term for Europe, and they could become part of the Swiss energy portfolio due to the planned phase out of nuclear power. Carbon capture and storage is considered an important option for the decarbonization of the power sector and it is the only way to reduce emissions in CO2 intensive industrial plants (e.g. cement- and steel production).
Building on the previously offered class "Carbon Dioxide Capture and Storage (CCS)", we have added two specific topics: 1) the industry of carbon-based resources, i.e. what is upstream of the CCS value chain, and 2) the science of climate change, i.e. why and how CO2 emissions are a problem.
The course is devided into four parts:
I) The first part will be dedicated to the origin, production, and processing of conventional as well as of unconventional carbon-based resources.
II) The second part will comprise two lectures from experts in the field of climate change sciences and resource economics.
III) The third part will explain the technical details of CO2 capture (current and future options) as well as of CO2 storage and utilization options, taking again also economical, legal, and sociatel aspects into consideration.
IV) The fourth part will comprise two lectures from industry experts, one with focus on electricity markets, the other on the experiences made with CCS technologies in the industry.
Throughout the class, time will be allocated to work on a number of tasks related to the theory, individually, in groups, or in plenum. Moreover, the students will apply the theoretical knowledge acquired during the course in a case study covering all the topics.

701-1653-00LPolicy and Economics of Ecosystem Services Belegung eingeschränkt - Details anzeigen
Number of participants limited to 50.
W3 KP2GR. Garrett, A. Müller
KurzbeschreibungThe course addresses ecosystem services, their value for society, the causes of their degradation, the stakeholders involved in their provision and use, and policies to reduce their degradation. One focus is on environmental economics approaches, highlighting their potential and limitations. During the spring of 2021 this course will focus on these issues through the case of the Brazilian Amazon.
LernzielStudents can describe, analyse and explain
• the basic concepts used to describe ecosystem services provision and management;
• the basic social and natural science theory underlying ecosystem service degradation,
• the role and characteristics of different key stakeholders involved in ecosystem services management, including their different value systems;
• the different types of policy instruments and institutional arrangements that can be used for improved ecosystem services management and provision; and
• empirical tools to assess the performance of various policy instruments and management systems for ecosystem services provision, and to investigate the factors of success or failure of different policy instruments
InhaltMany of the world's ecosystem services are being degraded or used unsustainably, which has considerable impacts on human well-being. Various aspects need to be taken into account to change this development, to work towards improved ecosystem services management and to design appropriate policy instruments and institutional contexts. First, the societal value of different ecosystem services and the trade-offs between them needs to be assessed. Second, an assessment of the causes of excessive ecosystem services degradation is needed. Potential causes include the presence of externalities and public goods, improperly designed property rights systems, divergence of private and social discount rates, and lack of information and knowledge. Third, we need to understand the drivers of human decision-making in relation to ecosystem services use. Fourth, choosing an appropriate policy instrument (or a combination thereof) requires an understanding of the relative strengths and weaknesses of different instruments, their preconditions for success and the political economy of their implementation.
Finally, it is important to assess the actual impacts of different policy and management options. This requires a careful assessment of appropriate baselines, of the situation after a policy or management change, and of the various stakeholder groups involved, etc. To address all these issues, we will first work with some broad conceptual issues and theories relevant to this field and then deepen our understanding through reading, presentations, and assignments focused on the case of the Brazilian Amazon.

651-1504-00LSnowcover: Physics and ModellingW4 KP3GM.  Schneebeli, H. Löwe
KurzbeschreibungSnow is a fascinating high-temperature material and relevant for applications in glaciology, hydrology, atmospheric sciences, polar climatology, remote sensing and natural hazards. This course introduces key concepts and underlying physical principles of snow, ranging from individual crystals to polar ice sheets.
LernzielThe course aims at a cross-disciplinary overview about the phenomenology of relevant processes in the snow cover, traditional and advanced experimental methods for snow measurements and theoretical foundations with key equations required for snow modeling. Tutorials and short presentations will also consider the bigger picture of snow physics with respect to climatology, hydrology and earth science.
InhaltThe lectures will treat snow formation, crystal growth, snow microstructure, metamorphism, ice physics, snow mechanics, heat and mass transport in the snowcover, surface energy balance, snow models, wind transport, snow chemistry, electromagnetic properties, experimental techniques.

The tutorials include a demonstration/exercise part and a presentation part. The demonstration/exercise part consolidates key subjects of the lecture by means of small data sets, mathematical toy models, order of magnitude estimates, image analysis and visualization, small simulation examples, etc. The presentation part comprises short presentations (about 15 min) based on selected papers in the subject.

First practical experience with modern methods measuring snow properties can be acquired in a field excursion.
SkriptLecture notes and selected publications.
Voraussetzungen / BesonderesWe strongly recommend the field excursion to Davos on Saturday, March 14, 2020, in Davos. We will demonstrate traditional and modern field-techniques (snow profile, Near-infrared photography, SnowMicroPen) and you will have the chance to use the instruments yourself. The excursion includes a visit of the SLF cold laboratories with the micro-tomography setup and the snowmaker.
