      Scientific Activities in Cycle Efficiency
             and Low CO2 Emissions
• Since 1988: Kalina cycles and Ammonia-water mixtures cycles
• Since 1993: HAT cycles, combined gas-steam cycles and gas
turbines based innnovative cycles
• Since 1997: CO2 capture and sequestration (CCS)
    simulation activities with Aspen Plus of several configurations of post and
   pre decarbonization, integrated with different types of plants.
    development of in-house models integrated with Aspen Plus for specific
   modelization of components

• Since 1998: High temperature fuel cells and hybrids
    experimental activities: our laboratory is the only Academic laboratory in
   Italy where MCFC and SOFC testing facilities are available.
    numerical activities in fuel cell and hybrids simulation with particular interest
   in the utilization of fuels derived from renewable energy sources (biomass)

• Since 2000: Biomass slow pyrolysis with gas turbines and
reciprocating engines
    simulation activities of small size pyrolysis gas fired gas turbines
    pilot plant with a biomass pyrolyzer and a microturbine installed at the
   University of Perugia.

                 Activities on CO2 Mitigation

• Numerical simulations of CO2 capture systems with commercial
softwares (Aspen Plus®)
• Devolopment of in-house built codes for modelling innovative
capture systems
• Techno-economic analysis of power plants (GateCycle®) with
integrated CO2 capture systems
• Studies for the installation of capture systems in existing
power plants
• Development of models and simulation of power plants with
pre- or post-combustion decarbonization

• Technical and economic analysis of CO2 mitigation technologies

• Biomass utilization in advanced power plants

• Fuel cells and hybrids using renewable energy sources

      International Master in Technologies for
           Greenhouse Gases Mitigation
is the one and only master in the world concerning this topic !

  The Master is organized by the University of Perugia, in cooperation
  with the Université de Liège (Belgium) and Mälardalens Högskola
  (Sweden).
                                      Objectives
  Governments, authorities, industry, consultants, need competent
  advisors who have a multidisciplinary formation ranging from physics of
  the atmosphere, economics of energy sources, engineering of power
  plants and energy systems, chemical engineering of capture and
  removal systems. This kind of education cannot be achieved with
  degrees in mechanical or energy or chemical engineering, but can be
  achieved in the framework of the International Master in Technologies
  for Greenhouse Gases Mitigation.

  The Master includes also professional teaching modules that allow the
  student to achieve a specialization for the auditing of GHG emission
  certification as foreseen in the EU directive 87/2003/CE (Emission
  trading).
