What is EXTRAQT and Its Aquathermy Project?
EXTRAQT is the go-to expert when it comes to aquathermal energy. This innovative project is all about using water as a sustainable heat source for buildings. The core idea? Harnessing the thermal energy stored in rivers, lakes, and canals through advanced heat pump technology. EXTRAQT develops sophisticated thermal models—digital twins of water bodies—that reveal just how much heat can be extracted without crossing nature’s limits. It’s a smart, software-driven approach that turns these natural water sources into operational heating installations, making aquathermy a practical and eco-friendly solution.
Main Benefits of Using Aquathermy
Why is aquathermy such a game-changer? Here are some key figures and facts that highlight its impact:
- 50% of global energy consumption is used for heating and cooling buildings.
- Only 14% of this energy currently comes from sustainable sources.
- Half of the world’s population lives within 3 km of surface water—an untapped renewable resource.
- EXTRAQT’s aquathermy technology can reduce emissions by up to 65% by tapping into the thermal energy of surface water.
- Digital twins help map the potential of aquathermy for entire cities, municipalities, and provinces, providing a clear master plan.
- Complete solutions from feasibility studies to technical design and installation ensure projects are realized from start to finish.
How Digital Twins Unlock Thermal Potential
At the heart of EXTRAQT’s approach are digital twins—virtual models of rivers, lakes, and canals that visualize their thermal potential. These models don’t just show what’s possible; they respect nature’s boundaries, ensuring sustainable heat extraction. By simulating different scenarios, these digital twins help planners and engineers understand exactly how much heat can be sustainably harvested. This means no guesswork, just data-driven decisions that balance energy needs with environmental care.
From Master Plans to Real Installations
EXTRAQT operates on two levels. First, it creates master plans that map out aquathermy potential across regions—cities, municipalities, provinces—you name it. This big-picture view helps stakeholders see the full scope of opportunities in their area. Then, it moves into action mode, offering end-to-end solutions. If a water body can supply the needed heat, EXTRAQT’s models design the technical setup and oversee the installation. The result? Fully operational aquathermy systems that deliver sustainable heating.
Success Stories That Speak Volumes
EXTRAQT’s expertise has been proven through numerous projects worldwide. From feasibility studies for local heat networks to detailed potential maps for entire provinces, their work spans a wide range of applications. Notable examples include:
- Modeling Hamilton Harbor in Lake Ontario, Canada.
- Installing open aquathermy systems in apartment complexes like ‘de Dijlemolens’ in Leuven.
- Developing closed aquathermy installations for historic sites such as the Castle of Laarne and the 14th-century Castle de Merode.
- Innovative projects funded by regional subsidies, like the aquathermy optimization model in Flemish Brabant.
- Collaborations within Interreg calls focusing on energy communities and sustainable cooling solutions.
Project Impact on Sustainable Development Goals (SDGs)
- SDG 7: Affordable and Clean Energy – Promoting renewable heat sources.
- SDG 11: Sustainable Cities and Communities – Integrating aquathermy into urban planning.
- SDG 13: Climate Action – Significantly reducing greenhouse gas emissions.
- SDG 6: Clean Water and Sanitation – Respecting natural water limits while using thermal energy.
- SDG 9: Industry, Innovation, and Infrastructure – Developing cutting-edge thermal modeling technology.
Why Aquathermy is a Climate Solution Worth Watching
Heating and cooling buildings account for half of the world’s energy use, yet only a small fraction is sustainably sourced. EXTRAQT’s aquathermy approach taps into a widely available, yet often overlooked resource: surface water. By rediscovering the heat stored in rivers, lakes, and canals, this technology offers a powerful way to slash emissions and meet energy needs responsibly. It’s not just about innovation—it’s about reshaping how communities think about energy, making sustainable heating accessible, efficient, and scalable. The future of clean energy might just be flowing right beneath our feet.
