 Austria: 1,5 TWh/a = 3,3 Mio. m²
(Weiss, 2006)
 Germany: 16 TWh/a = 36 Mio. m²
(Lauterbach, 2011)
 EU 25: ca. 70 TWh/a = 155 Mio. m² (Vannoni, 2008)
Based on the actual technology appr. 34% of the thermal energy demand of

Combining process intensification and solar
thermal systems
Analysis of the effect of upcoming technologies on the
potential for solar (heat) in industry
Positive effects (enhancing the potential), negative effects
(decreasing the potential) e.g.:
effect of microwave drying on solar drying processes?
contribution of UV disinfection to industrial processes?
effects of direct steam injection technologies e.g. direct steam
injection in boiling (potential for high temperature collectors)
less heat recovery from boiling for water preparation  increasing
potential for solar hot water preparation
Lower wash water needs due to process intensification 
decreasing potential for solar hot water preparation
. Identification of promising technology changes that will
enhance the potential for solar (heat) in processes and the
respective research needs
e.g. continuous processes in the food industry; low temperature
processes; static mixers for enhanced heat/mass transfer; photo
catalytic processes etc.

B4. Workshops on new process technologies (one at beginning, one
when potential new applications are known together with solar
collector developers)
To provide a sound basis to the work foreseen and stimulate the knowhow exchange between experts from conventional process
technologies with solar process technologies, a dedicated workshop
will be done for new process technologies that can potentially be
driven by solar
.
1st Workshop: Overview of new technologies - Which new
technologies are/might be relevant?
Planned: Begin of September 2012 in Graz (in the frame work of
Gleisdorf Solar)

Objectives:
 a worldwide overview of results and
experiences
 to develop a performance assessment
methodology for a comparison and
analysis of different applications,
collector systems, regional and
climatic conditions
 to support future project stake holders
by providing design guidelines,
