Wind Energy

Wind tunnel lab

The Open Jet Facility, normally only called by its abbreviation OJF, is a wind tunnel with an open test section. This allows for measurements of flows around larger obstacles, such as models of wind turbines.
The Low-Speed Low-Turbulence Wind Tunnel at TU Delft is used to measure the two-dimensional aerodynamic characteristics of wind turbine dedicated airfoils.

Unmanned Valley Valkenburg

The former airport Valkenburg is used as outdoor testing facility for airborne wind power. A total makeover of the former airport is planned to turn it into a high-tech test site for unmanned aerial vehicles and airborne wind energy systems.



Solar Energy

Photovoltaics lab

Working with real system components, taking measurements and performing analysis, is at the heart of the educational experience. For that reason the PVLAB is equipped with the latest measurement equipment, off the shelf system components, and a full size certified solar simulator.


The TU Delft has multiple cleanrooms. The necessary tools and fabrication methods are available to make and measure photovoltaic cells.

Biomass Energy

Macrolab with:

  1. 5 kg/h bubbling fluidized bed biomass gasifier, steam-oxygen blown; including hot gas (catalytic) ceramic filter
  2. 10 kg/h indirectly fired bubbling fluidized bed gasifier, steam-blown
  3. Fixed bed torrefaction reactor suitable for a wide range of biomass types
  4. Fixed bed catalytic reactor for kinetic studies of conversion of (biomass derived) gaseous compounds
  5. Thermogravimetric analyser combined with FTIR for biomass and char characterization (slow heating rate)
  6. Pyroprobe analyser combined with tar trap for biomass characterization (fast heating rate)
  7. Heated grid reactor with in-situ FTIR for biomass characterization (fast heating rate)
  8. Electrochemical reactor for conversion of e.g. biomass derived CO2 to produce fuels
  9. Accompanying analytical facilities, like autoclave, HPLC’s, GC’s, bomb calorimeters


Multipurpose facility

This facility at the Chemical Engineering Department provides the infrastructure for making nanostructured materials, that can serve e.g. as a catalysts to convert biomass streams. By combining atomic layer deposition with fluidized bed reactors, scalable amounts of these materials can be made.

Radiation lab

This lab has the unique capability of applying both X-ray tomography and radioactive particle tracking to study the flow behaviour of multiphase flows such as fluidized beds. This knowledge can be used to optimize e.g. fluidized bed combustors and gasifiers.



DENLab is a renewable energy lab located at the Electrical Power Systems Group of the Electrical Sustainable Energy Department of Delft University of Technology. The objective of this laboratory is to serve as a test facility for projects focused on small-scale renewable energy systems.

Real-Time Digital Simulator

The RTDS consists of a large number of parallel processors that can be controlled through software that runs on a pc. The time step of the computations is 50 microseconds, which enables the user to operate the simulated power system interactively in a way that is similar to the real system.
