The Delft Geothermal Project (DAP)
On Tuesday 20 May, the Department of Mining organised a lecture on the Delft Geothermal Project (DAP).
(Deep) Geothermal Heat is increasingly being cited as one of the most promising sustainable energy sources of the future
In May 2007, a project was started by a number of initiators within TU Delft, Department of Applied Earth Sciences, to further map the potential of this technology. The aim is to extract heat (local water temperature +/- 75 °C) from an aquifer of sandstone at a depth of about 2,000 metres via a special production well. This 'water-well' will be drilled with an innovative 'light' drilling rig and using so-called 'composite casing drilling technology'.
The heat will be used in an above-ground exchanger to heat the TU district (instead of a 1 MW boiler system, as currently in use). Apart from this, the possibility will be studied of pumping CO2 into the sandstone layer with the returning water flow in a second phase (i.e. CO2 storage). This would achieve a double reduction in CO2 emissions.
In short, the Delft Geothermal Project integrates a number of highly innovative applications, with the main aim of making a relevant contribution to the greenhouse gas problem. A consortium consisting of the university, industry and government has now been formed to further elaborate and optimise the project.
Mr Andries Wever (ir. Mb 2004) explained the basic ideas behind the project and its implementation, Mr Tom Bakker (ir. Mb 1974) explained the underlying drilling technology.

Description
(Deep) Geothermal heat is increasingly being cited as one of the most promising sustainable energy sources of the future.
In May 2007, a project was started by a number of initiators within TU Delft, Department of Applied Earth Sciences, to further explore the potential of this technology. The aim is to extract heat (local water temperature +/- 75 deg C) from an aquifer of sandstone at a depth of about 2,000 metres via a special production well. This 'water-well' will be drilled with an innovative 'light' drilling rig and using so-called 'composite casing drilling technology'.
The heat will be used in an above-ground exchanger to heat the TU district (instead of a 1 MW boiler system, as is currently in use). Apart from this, the possibility will be studied of pumping CO2 into the sandstone layer with the returning water flow in a second phase (i.e. CO2 storage). This would achieve a double reduction in CO2 emissions.
In short, the Delft Geothermal Project integrates a number of highly innovative applications, with the main aim of making a relevant contribution to the greenhouse gas problem. A consortium consisting of the university, industry and government has now been formed to further elaborate and optimise the project.
Mr Andries Wever (Ir. Mb 2004) will discuss the basic ideas behind the project and its implementation, Mr Tom Bakker (Ir. Mb 1974) will give an explanation of the underlying drilling technology.
After the lectures, there will be an opportunity to chat over drinks.
