Netherlands: 4,000 Meter Deep Geothermal Well Being Drilled for Greenhouse Warming Project

Geothermal heat for Westland greenhouse region near The Hague (

Work on boring a four-kilometer-deep shaft below the Westland greenhouse growing region near The Hague has begun, the Financieele Dagblad  reported on Thursday. 

The pilot Trias Westland boring tower will be operative in September but it will be December before the first geothermal heat will be pumped up to serve the vast flower and vegetable growing greenhouses in the area. The heat comes in the form of water heated to 140 degrees. 

The €50m pilot project will be twice the size of other geothermal heating plants in the Netherlands. Trias Westland director Marco van Soerland said geothermal projects are much more expensive than solar panels as a heat source. 

The Westland auction as well as 43 growers have committed to buying the geothermal heat which, if successful, is expected to provide between 10% and 20% of annual heating needs.
