Island of Vlieland
In Vlieland's
harbour, heat will be extracted from seawater with collectors placed behind the
dam walls. A feasibility study carried out by consultancy firm, Ekwadraat
showed that this form of aquathermal energy could generate enough heat that
almost the whole of Oost-Vlieland could be sustainably heated. The collectors
in the sheet piling can only be installed when the sheet piling is replaced, it
is therefore important to seize the opportunity that is now available due to
the replacement of the quay wall.
A project plan has therefore been drawn up for a small-scale pilot (a pilot project), which can be expanded in the future. The project plan is called 'Business Park Vlieland Gas-Free'. The pilot consists of two phases, with phase 1 connecting the harbour office and the municipal workshop to the aquathermal heat network with thermal storage. The energy required for the heat will be generated by means of collectors in the sheet piling and collectors on the roofs. In phase 2, the heat network will be further expanded by connecting around five buildings in the business park. The innovation of this heat system lies in the fact that the generation and delivery of heat is by a combination of low-temperature (aquathermal) and high-temperature (solar thermal). These techniques have been proven individually in practice; however, the combination of techniques makes this pilot special.
If the system is sufficiently commissioned and
meets expectations, the system can be scaled up further. Because this system appears
to be very realistic and feasible, there is widespread interest in how it will
work in practice. If the pilot succeeds, there is a strong chance that this
system will be rolled out further across the island, first connecting the
industrial estate and later the village of Oost-Vlieland.
