This document outlines an agenda for a geothermal energy get-together at TU Delft. The agenda includes coffee and welcome from 14:30-14:50, followed by presentations on TU Delft's past and current geothermal energy research from 14:50-15:20 and 15:20-15:40. There will then be a coffee break from 15:40-16:00 before presentations from 16:00-16:40 on the proposed design of a geothermal well to be drilled on the TU Delft campus. The event will conclude from 16:40-17:00 with an overview of TU Delft's geothermal energy program and drinks from 17:00 onward

• 2007 Started with a group of students and a good idea.
• Grown over years.
• 2013 Appointment of Prof David Bruhn (support of DAP,
industry, alumni)
• 2018 Geothermal theme

Internal: Department / TU
• Coordination of activities
• Applying expertise to application area
• Better research
• Better education
External: industry / society
• A single way into the research
• Communicating research output effectively
• Communicating with industry effectively
• A way of demonstrating expertise depth
• Tackling more general questions

‘We have the vision that TU Delft will become a knowledge centre and a
global player for Geothermal research and development. We will utilise
our expertise and skills to grow a substantial research and educational theme on
Geothermal Energy within the Department of Geoscience and Engineering
(GSE).
We commit to considerably expanding our research infrastructure and
capabilities to deliver this vision. The geothermal doublet on campus (DAPwell)
will be a unique and integral part of the geothermal research infrastructure. It
will add a critical component to the current engagement of TU Delft within the
energy transition (e.g. wind, solar, smart grids), as heat makes up ~80% of the
energy use in the urban environment.

Embedding in existing programmes
• AES BSc (new introduction courses)
• AES LDE minor in Georesources (new 2017)
• Petroleum MSc track
• Currently in 1 course, 2 electives (incl. a field trip)
• Proposed replacement track: Geo-energy. 2
courses
• 4TU SET MSc
• 1 course
• MSc and BSc theses
Focus now on robust embedding – not a new programme/track.
Education

11. 11
A team approach: Opportunities
• Deep geothermal
• Monitoring
• Prediction and self learning
• Variability
• Aquifer Thermal Energy Systems (ATES)
• As above
• Increasing temperatures
• Increasing efficiencies
• Shallow geothermal
• As above
• Integration with structures
• Integration with electrical grid
• Low risk design
• System and heat networks
• Planning and scheduling
• Integration with buildings
• Long term monitoring
• Data assimilation
Opportunities: research/valorisation

12. 12
A team approach: Facilities
• Delft Aardwarmte Project well (DAPwell) Project to develop
a geothermal well on campus, offering a chance to trial new
technology and monitoring. Can be a European test bed.
• Delft thermal grid. Existing heat grid on campus, possibility to
test prediction, storage and planning.
• Energy pile. A 10m deep energy pile at the Green Village to test
thermo-mechanical behaviour.
• Thermal laboratory. A number of experimental facilities exist
and will be further developed, to have thermal control and
thermal loading. Combined with partners.

• ~2km deep well – into the Delft sandstone.
• Collaborations:
• Internal university (department, faculty, facility
management)
• Partners outside (universities, companies, organisations)
• Provide substantial heat to TU campus and surroundings
• Large-scale research infrastructure
• Reference well – extremely well instrumented during
installation and operation
• Allowing measurement campaigns during measurement.

15. 15
• Large-scale research infrastructure
• Partial financing in place
• SDE+ approved
• Project team appointment to make project plans:
• Project manager to perform overall project management
and establish the necessary legal entities (Warmte BV,
etc.)
• Well designer for the detailed well engineering design
and alignment of scientific and operational requirements
• Final university decision pending
• Distribution of heat
• Negotiations with new partners look promising
