Energy Smart Solutions is a Start-up Spin-Off of Nanyang Technological University Singapore. The company core business is related to the energy optimization for achieving large greenhouse (CO2) and primary energy consumption reduction, and capital and operating costs savings. In the energy sector, consumers are becoming prosumers, and traditional centralized power plants are being replaced more and more by distributed smart multi-energy systems in which electricity, cooling and heating are concurrently demanded and generated. The ©E-OPT software developed under Energy Smart Solutions allows for solving (our poster here).

After having graduated and during the PhD period, I've been working under the European Founder Project H2-IGCC with a cooperation contract. Aim of the project was to demonstrate the feasibility of Carbon Capture & Storage in IGCC power plants, by running the Gas Turbine with a Hydrogen Rich Fuel, cleaned from the Greenhouse pollutants, in order to achieve a clean combustion process with a reduction in CO2 of 95-98%.
The activities carried out have been the following:
​
-
Development of component models for Gas Turbine Combined Cycles power plants (i.e. Compressor, Expander, Combustion Chamber, Heat Transfer Devices, Steam Turbine and other rotary machines).
-
Development of lumped models for Gasification island of the power plant (i.e. Shift Reactor, Gasifier, ASU).
-
IGCC plant simulator has been realized and it has been validated through the data available by the manufacturers, being partner of the project.
EDUCATION
DOCTORAL SCHOOL of MECHANICAL AND INDUSTRIAL ENGINEER (PhD)
Roma Tre University
​
01/2011 - 06/2014
Rome, Italy
Under the H2-IGCC EU project, I’ve been involved in the development of component models for IGCC with Carbon Capture and Storage Power Plants to build up the H2-IGCC power plant simulator. During the three years of the doctoral school, I’ve focused the research activity on energy conversion systems, turbomachinery and optimization techniques, together with a deep analysis of quasi-Newton and Genetic Algorithms solution methods. After a preliminary cycle calculation, design (sizing) of machines (compressor, expander, steam turbine, etc.) and apparatuses (heat transfer devices super-heater, boiler, economizer) has led to develop models for establishing components off-design maps (gas turbine, steam turbine, condenser, pump, combustion chamber, etc.). Such maps once matched together have allowed to define the whole H2-IGCC plant simulator. Accordingly, such a simulation tool has been adopted to perform part load analysis that brings to establish the best plant control policies in terms of objective function (i.e. costs or earnings) minimization or maximization. To reduce the CPU occupancy and to short the calculation time, properly Neural Network component models have been built up

10/2007 - 05/2010
Rome, Italy
Master Degree Thesis has been addressed to solve an existing engineering problem, concerning a CHP plant. It was a team work together with two other students (friends). I’ve dealt with Heat Recovery Steam Generation and steam turbine sizing and off-design maps establishing. I’ve learned Fortran 77 programming language and quasi-Newton solution techniques. Moreover, I’ve realized a neuralized (NN Techinque) model for the whole CHP steam island.

Rome, Italy
Bachelor Degree Thesis has been oriented to determine the flow function coefficients of a properly designed device to realize mechanically, by mean of shock waves, emulsified fuel to be used both in the reciprocating engines and in gas turbine burners. I’ve learned how to build up a test bench and how to plan the experimental tests. Such lab tests have allowed to validate forecasted data obtained by a simulation code.
