Thema: Decentralised low-carbon energy systems: resource potentials, self-sufficiency and energy system transformation
Abstract: In the context of ambitious energy and climate goals, the energy system is undergoing a structural transformation through increased energy efficiency and low-carbon technologies. On the one hand most of these technologies are decentralised in nature, on the other it is uneconomic to transport heat large distances. So the future energy system will be more decentralised, including a lot more actors, generators and a stronger interaction between all parts of the system This lecture will highlight some previous and ongoing research of the speaker in this context, based on interdisciplinary methods of techno-economic and energy systems analysis. We begin with some context relating to this decentralisation, grid parity, prosumers and energy autonomy. We then introduce some previous work on resource assessments for renewable technologies, with a focus on attempting to consider non-technical constraints such as social preferences and acceptance. Attention then turns to research on the demand side, with a bottom-up stochastic simulation model to generate heat and power demand profiles for residential buildings. The scale then moves to the district and municipality, where we explore several studies investigating the impact of low-carbon technologies at individual building and district scales. This is followed by some examples of the author’s research relating to energy autonomy at different spatial scales and based on diverse supply configurations. The presentation closes with an outlook over current and future research, including improvements to existing methods and developing a quantitative framework to understand the scale effects of highly-renewable energy systems.

Referent: Dr. Tobias Bischof-Niemz, Bereichsleiter Neue Energielösungen, ENERTRAG SE
Thema: Grüner Wasserstoff für die Schweiz
Abstract:
Roughly 500-600 Mt/a of green hydrogen will be required globally in a decarbonised world with the primary energy being predominantly wind and solar electricity. The electrolysis that produces the green hydrogen from electricity will play three roles: First, it will separate between low-value and high-value electricity, lower-value supplying the electrolyser, higher-value going into the electricity sector. Second, it will couple sectors to the electricity sector that are not possible to decarbonise through electricity (e.g. iron ore reduction). Third, it provides a storage function in the energy system.
A very substantial part of the globally required green hydrogen will find its end use not in form of straight hydrogen, but in form of derivatives that are inherently easy to trade and ship, such as ammonia (for fertiliser, explosives and as shipping fuel), methanol (as chemical feedstock and as shipping fuel) and kerosene (as aviation fuel).
ENERTRAG is developing green hydrogen projects globally in all three product categories – in Namibia (ammonia), in Uruguay (methanol) and in South Africa (kerosene). This presentation will give an overview of the current status of those developments, the specific technical configurations and challenges, and what needs to be done on the regulatory side to make these product markets work.

Referentin: Professor Annalisa Manera, Nuclear Safety & Multiphase Flows,
Department of Mechanical and Process Engineering, ETH-Zurich
Thema: Nuclear energy – new developments and its role in the Swiss energy mix
Abstract:
Following a brief introduction to Switzerland’s current energy mix and the projected electricity requirements based on the 2050 energy scenarios, this presentation will center on the present state of nuclear energy in Europe, as well as globally. Emphasis will be placed on its significance in achieving carbon-neutral electricity generation and its broader applications. The discussion will encompass recent advancements in technology, spanning from large nuclear power plants to small modular reactors and microreactors, from Gen-III/III+ to Gen-IV, from terrestrial to space applications.
Short Bio:
Dr. Manera is Professor of Nuclear Systems and Multiphase Flows at ETH Zurich and group leader at the Paul Scherrer Institute. Starting July 2021 she is on a leave of absence from the University of Michigan, where she has been Professor in the Nuclear Engineering Department since 2011.
Her research group focuses on the development of high-resolution experimental techniques and high-fidelity multiphysics computational tools for the analysis of nuclear systems, with applications ranging from operating nuclear power plants, to small modular reactors and microreactors.
She holds a M.Sc. in Nuclear Engineering from the University of Pisa (110/110 summa cum laude) and a Ph.D. in Nuclear Engineering from the Delft University of Technology.

Thema: Using CO2 as a high-efficiency working fluid for baseload and dispatch geothermal power generation and for geologic CO2 sequestration
Abstract: Carbon capture and geologic storage (CCS) can be utilized to generate geothermal heat and electric power highly efficiently, while still eventually sequestering all initially subsurface-injected carbon dioxide (CO2) underground. I called the system a CO2-Plume Geothermal (CPG) power plant, where captured CO2 is circulated underground in deep saline aquifers or depleted oil/gas reservoirs. During CPG operations, the CO2 is naturally geothermally heated in the CO2 storage reservoir, produced to the surface, where it is either directly used for heating or expanded in a CO2 turbine to generate electricity. After the turbine, the CO2 is cooled, condensed, compressed and then combined with the CO2 stream from the CO2 capture facility before it is reinjected into the original subsurface CO2 storage reservoir. The reinjection results in the continued growth of the subsurface CO2 plume and ensures that 100% of the subsurface-injected CO2 is eventually permanently sequestered underground. CPG has been co-invented by Prof. Saar, who has founded an integrated industry-academia CPG Consortium (https://geg.cpg.ethz.ch) in March 2023, which is in the process of planning a CPG field demonstration and subsequent CPG commercialization.
CO2 can also be used as the geothermal energy extraction fluid in deep, closed-loop Advanced Geothermal Systems (AGS), significantly improving their electric power generation efficiency. While all deep geothermal systems can provide baseload power and are quite suitable for providing dispatch-capable power, AGS are particularly suited to provide dispatch-capable power. Therefore, we envision countries worldwide, including Switzerland, to install such AGS as “backup power” for only intermittently available solar and wind power. Such AGS solar and wind backup power has no operative CO2 emissions is becoming more and more critical to implement during many countries’ energy transition efforts to reach net-zero CO2 emissions by 2050, including Switzerland. Therefore, Switzerland is supporting these AGS research and development efforts with an Innosuisse Flagship project entitled “AEGIS-CH: Advanced geothermal systems to improve the resilience of the energy supply of Switzerland”. The 4-year AEGIS-CH (https://geg.ethz.ch/aegis-ch/) project started June 2022.
Short Bio: Professor Martin. O. Saar is the chair of the Geothermal Energy and Geofluids group in the Department of Earth Sciences at ETH Zurich, Switzerland.
Professor Saar received his Pre-Diploma in 1995 in Geology from the University of Freiburg, Germany, his MSc. in 1998 in Geology from the University of Oregon, USA, and his Ph.D. in 2003 in Earth and Planetary Sciences (Geophysics) from UC Berkeley, USA. He was then the Turner Postdoctoral Fellow in 2003-2004 at the University of Michigan, USA, and then the Gibson Chair for Hydrogeology and Geofluids as well as a Geology and Geophysics Assistant, Associate, and Full Professor at the University of Minnesota – Minneapolis, USA, from 2005 through 2014. Since 2015, he has been at ETH Zurich in Switzerland, where he founded the GEG group, which is endowed by the Werner Siemens Foundation.
His research interests are in geophysical fluid dynamics of subsurface multiscale, multiphase, multicomponent, reactive fluid (groundwater, hydrocarbon, CO2) and energy (heat, pressure) transport, such as water- and CO2-based geothermal energy utilization, geologic CO2 storage, grid-scale energy storage, enhanced oil recovery, and groundwater flow. Methods include computer simulations, laboratory experiments, and field analyses.
