Hello everybody,

I learned from Johannes about this forum. Just like Johannes, I did a PhD at Paul Scherrer Institut and the Swiss Federal Institute of Technology in Zurich in the field of Biomass Gasification. I wish I had known this forum back then because one of the goals of my thesis was to come up with a fixed bed gasifier in the 5 to 30 kWth scale which would operate at least one week non-stop. Fortunately, I did succeed in the end as you can read in my thesis.

Electricity from wood through the combination of gasification and solid oxide fuel cells

Danish Technological University Updraft Gasifier Plant
DTU, Denmark, September 1, 2009

DTU Updraft Gasifier and Stirling Engine

Today, operation started on Stirling DK's latest installation situated on the campus areas of the Technical University of Denmark (DTU). Approximately 1% of DTU's total power consumption and 2% of its heat consumption will be supplied by the installation.

The plant includes a Stirling engine with an output of 35 kWe of electrical power. The surplus heat from the plant, in the form of hot water, is fed into the district heating system of the DTU campus.

The plant is fuelled by wood chips originationg partly from cuttings from DTU park areas. In this way, the plant is a stand-alone facility that enables DTU to become partly self-sufficient with CO2-neutral power and heat from locally availabel fuel sources.

More information about the project can be found here.
