Zeeland heat and cold

Thermal heat from surface water

The consequences of climate change are becoming increasingly clear. Partly because of the long coastlines, Zeeland is faced with sea level rise and extreme weather; but because of its location by the sea and former sea-arms it also has good maps in the energy transition. The combination of available space, the enormous wind potential and the most hours of sunshine in the Netherlands ensure that the government also looks to Zeeland as a region where a lot of electricity can be generated. In addition, the region has an additional asset in its hands due to the invisible but enormous heat potential in the ubiquitous surface water. The possibility of own electricity and a heat supply based on surface water gives the region the opportunity to lead the way in the energy transition.

In order to prevent the ambition for a fully sustainable energy system in 2050 at the expense of the landscape quality and tranquility in the province of Zeeland, and with that, public support, in this future perspective is chosen to fully focus on collective heat supply for households. This deliberately does not opt ​​for a vision with, for example, floating solar panels, but rather for a measure with a large climate impact - most CO2 reduction - combined with a low spatial impact.
Because there is no proven geothermal potential (geothermal) in the subsurface in Zeeland, electric heating of households is a good option. However, without a collective approach there is a risk that residents will purchase the inexpensive but noisy electric outdoor air / water heat pump on a large scale. This type of heat pump can significantly disturb the peace and quiet in the province. An alternative is the water / water heat pump fed by thermal energy (heat) from surface water. The basic temperature of the water (± 12 oC) is upgraded using this type of heat pump. This means less electricity is needed to reach comfortable room temperatures. For example, the installation of collective heating systems can prevent an additional need for electricity in the form of wind turbines. The fact that this requires additional investments in, among other things, bronnets - to distribute the heat from surface water - is accepted in this perspective by the province and society.
