Research Centre for Energy Resources and Consumption

Zaragoza, Spain


CIRCE Foundation (Research Centre for Energy Resources and Consumption) was established in 1993 as an independent Centre of Research by the University of Zaragoza, the Regional Government of Aragon and different industrial partners. CIRCE currently has a staff of over 150 full time people. The variety of profiles and the multidisciplinary nature of the staff allow CIRCE to create the most efficient team for each case. Since 1993, CIRCE has conducted more than 1.200 projects, being the 2008 approximated budget of 6 M€ (including the Masters run by CIRCE). In the year 2001, CIRCE was recognised as a National Innovation and Technology Centre. CIRCE´s first commitment is with the energy efficiency, low carbon technologies and renewable energies, from the assessment of resources for generation, the transmission and distribution to the rational use of energy. Currently CIRCE holds the management of the European projects office of the Spanish Technologic Platform of the CO2.

Relevant European projects related to SENERES objectives:

  • ENERCORN, Demonstration of a 16 MW high energy efficient corn stover biomass power plant; European Commission FP7.
  • BIOMAX, Maximum Biomass Use and Efficiency in Large-Scale Co-firing, European Commission FP5 no NNE5/2001/291.
  • CFB 800, Utility Scale CFB Competitive Coal Power; European Commission, RFCR-CT-2005-00009.
  • CLEAN SELECTIVE, Intelligent monitoring and selective cleaning control of deposits in pulverised coal boilers, European Commission, RFCR-CT-2006-00008.
  • INTCON, Intelligent Process Control System for Biomass Fuelled Industrial Power Plants, European Commission FP5 / ENK6-CT-2001-00542.



Key person

Luis M. Romeo (Ph.D. Mechanical Engineer), is Project Manager in CIRCE and lecturer of “Thermal System Simulation” and “Zero Emissions Technologies, Carbon Capture and Storage” at the University of Zaragoza. He gained his professional experience developing and managing several projects in different Spanish power plants such as Pressurised Fluidised Bed Combustion, Pulverized Coal, Combined Cycles and Biomass Boilers. Since 2002 he has focused its activity on CO2 emission reduction, energy integration and CO2 capture systems (oxyfuel and CFB looping). He collaborates with the Spanish Platform of CO2 and is involved in CO2 capture projects (Oxyfuel, amine scrubbing and calcium looping)
