Energy Geostructures

Harnessing the Power of the Ground: Energy Geostructures for Sustainability
To meet global carbon neutrality goals, we need innovative solutions like energy geostructures. These structures transform everyday building elements – foundations, walls, tunnels – into renewable heating and cooling systems. Imagine a building’s foundation also serving as its geothermal energy source!
The Challenge and Our Solutions
Designing energy geostructures is complex. They must provide structural support while handling unique thermal and mechanical stresses from the ground. Our research at the LMS tackles these challenges head-on. Here’s what we do:
Understanding the Science: What happens inside the ground when these structures provide both support and energy?
Engineering Solutions: How do we optimize energy geostructures for energy efficiency, structural soundness, and long-term performance?
Practical Applications: We help engineers and designers implement energy geostructures with confidence, spreading this sustainable technology.
Why This Matters
Energy geostructures offer a powerful way to reduce the carbon footprint of buildings and infrastructure, a key piece of a greener future.

Multiphysical modelling of sustainable geotechnics with a focus on biocementation and energy geostructures – Sofie ten Bosch
In the fields of geotechnical and geo-environmental engineering, there’s a trend emerging where researchers are increasingly using multiphysical methods targeting to develop integrated approaches leading to smarter construction methods and more efficient use of energy, especially in sustainable engineering projects.
The present thesis puts the focus on two distinctive applications which have been identified as promising innovations to tackle the question “How can we make geotechnical systems more resilient and sustainable?”. These innovations are the use of biocementation and energy geostructures. Multiphysical modelling contributes to the development of the understanding of underlying mechanisms involved in these problems and remains an essential tool for their design.
Numerical modelling of biocementation within this thesis focuses on projects representative of real geohazard mitigation problems, including foundation strengthening or slope stabilization using biocementation. This is essential for the step towards design principles for this technology, which is crucial for innovation adoption. On the side of energy geostructure applications, the challenge remaining to be addressed is to extend the domain of application beyond its conventional considerations and demonstrate their effectiveness in alternative scenarios, in for example underground data centres or metro stations. In doing so, this work aims to support future sustainable geotechnics applications and accelerate their innovation adoption.

Tech – Transfer

ENERDRAPE
We developed the first geo-thermal panel that efficiently captures both geothermal and waster heat in existing indoor environments located in the underground and transfers it for renewable heating and cooling to buildings. Unlike conventional geothermal systems, the technology developed relies on a non-invasive installation, allowing the use of shallow geothermal energy in existing buildings. The modular geo-thermal panels are meant to be installed in existing underground indoor environments such as underground parking, underground transportation hubs, tunnels etc. With the modular geo-thermal panels we facilitate access to renewable shallow geothermal energy to existing buildings while reducing capital investments, operation costs and CO2 emissions.
