Heating a fortress with aquathermal energy
What shall we do with our old fortress?

.

Edegem has something in common with the municipalities surrounding Antwerp: a fortress from the historic Antwerp Fortress Belt. Fort 5 has long ceased to be a military domain, and the municipality of Edegem aims to prepare the old hangars for a sustainable future. One of the technologies under consideration is aquathermal energy — the use of heat extracted from water. EXTRAQT was brought in as an expert to carry out a feasibility study.

Aquathermal source peak demand

1,5 MW

CO2-reduction

100%

Surface waterboy

15 000 m2

Illustration of the use of a closed aquathermal system at a castle by a lake
How big is the potential of aquathermal energy?

.

During the study, factors such as pond depth, thermal potential, practical challenges, ecological benefits, and financial feasibility were assessed. The results proved both interesting and highly promising.

With so much water nearby, the site has an impressive thermal potential of 1.5 MW, sufficient to heat 300 households. Moreover, the ground surface is remarkably even, allowing heat exchangers to be installed easily. After the planned renovations, it will definitely be worthwhile to integrate aquathermal energy into the buildings on and around the site. The large hangars have a significant heat demand, which also makes the project economically attractive. Other sustainable technologies make the benefits of aquathermal energy even more attractive. By combining it with a green electricity contract and solar panels, CO₂ emissions can be reduced by 100%.As a conclusion, there are plenty of reasons to make aquathermal energy a reality here.
