Parallel session descriptions:
1A. Energy Geostructures (chair: Phil Vardon, TU Delft)
One of the key barriers to implementing shallow geothermal energy is installation cost. Therefore, combining heat exchangers with structural elements, i.e. energy geostructures, is attractive as the additional costs for the energy component are minor. Energy piles and energy walls are two types of these structures which have a wide applicability in urban environments. The impact of the energy harvesting / storage in these systems affects the mechanical behaviour. Both the energy and the mechanical design requirements must be both satisfied. This session will cover some of the recent innovations and experiences with energy geostructures.
1B. Energy Storage (chair: Jan Willem Rösingh, PEP)
We are currently in a global energy transition phase. Where currently electricity and heat is largely generated by fossil fuels, we are moving into a new era where this energy will be largely generated by renewable sources. Especially the supply of wind and solar-based electricity is driven by the elements, which not always match the demand. Geothermal energy can provide a basic steady source of heat. However, the demand for heat in urban areas is the largest in winter. This mismatch in supply and demand makes (temporary) energy storage thus very important. Storage of energy in the subsurface or in other materials provide in many instances a good solution.
2A. Material Behaviour (chair: David Smeulders, TU Eindhoven)
Due to the inherently intermittent nature of renewables, there is a strong mismatch between energy supply and demand, both in space and time. This requires revolutionary new concepts for geotechnical energy storage and transportation. Examples are thermo-chemical and adsorptive materials for heat storage, subsurface heat or ice energy storage, compressed air storage in salt caverns or porous formations, chemical energy storage using hydrogen gas, methods for high-temperature thermal heat storage in shallow depths or reverse electrodialysis (RED) for energy generation. In all of these applications the understanding of coupled thermo-hydro-mechanical and chemical processes in porous media is of paramount importance for dimensioning and operating the storage systems as well as for an environmental impact assessment. This session focuses on recent advances and examples of geotechnical energy storage.
2B. Offshore Energy Geotechnics (chair: Joek Peuchen, Fugro)
This session focuses on opportunities and geotechnical challenges for offshore energy for the Dutch sector of the North Sea. The activity level for the Dutch sector of the North Sea is high and changing. Assets for wind energy are rapidly expanding. In contrast, existing facilities for oil and gas will gradually be decommissioned. Re-use of some of these facilities is being considered for production of hydrogen, CO2 capture/storage in depleted gas fields and geothermal applications. The session will cover topics such as geodata for geotechnical assessment of the seabed for design, construction and maintenance of offshore facilities including monopiles and cables, assessment of mobile seabed conditions (e.g. scour and deposition of sand), efficient and economical geotechnical design of monopiles, and novel pile installation methods for reducing marine noise.
3A. Induced Seismicity (chair: Siefko Slob, Cohere Consultants)
Natural earthquakes occur in areas with active tectonic stresses. However, in absence of active tectonic stresses, earthquakes can also be generated by disturbing the delicate equilibrium of stresses present in the subsurface. This is often caused by human activity and this is called induced seismicity. The disturbance can be caused by gas extraction, geothermal heat extraction, wastewater injection, filling of water reservoirs, mining or hydraulic stimulation. In the Netherlands, the Groningen area has been affected by induced earthquakes due to gas extraction. In this session the origin and consequence of the Groningen earthquakes are discussed. We will also provide an overview of the causes and mechanisms of induced seismicity.
3B. Heat Extraction & Distribution (chair: Jorien Schaaf, EBN)
The Netherlands is aiming to drastically reduce CO2 emissions; geothermal energy is one of the means to reach this goal. A steep increase of the number of geothermal doublets is foreseen in the Netherlands to be able to supply around 30% of the current demand for heat. In this session we will discuss a wide range of geothermal subjects starting from reservoir geomechanics all the way to play-based heat extraction and ways to optimally extract heat from the subsurface in a sustainable way, answering the question how the small-scale geotechnics influences the larger play-based heat supply.
Innovative Ideas and Concepts (chair: Jacco Haasnoot, CRUX)
We give an open podium to professionals and engineers that have an innovative concept or idea in the field of Energy Geotechnics to pitch their novel concept. This will provide an opportunity to be challenged by a the expert audience and to find partnerships to bring the concept to a next level.
So, if you have an innovation or new concept which fits the theme of the symposium, contact the organizing committee.
