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).

As a recognized and awarded expert in the energy efficiency and optimization sector, I've been hired as a member of a consultant team in order to define a road map for achieving Energy and CO2 Footprint Reduction  for Shell Jurong Island Petrochemicals Complex. Through Pinch Point Analysis technique and energy optimization, integration of new technologies and retrofitting the actual plant configuration are being explored. CO2 reduction up to 20% has been obtained, in respect of the actual plant configuration.

I'm working since July 2016 under the 18M$ Singaporean Found Project Smart Multi Energy System (SMES) on the Work Package on the Poolygeneration systems.  During the last three years, together with our team and with the supervision of Prof. Alessandro Romagnoli, I've been carrying out research activities in Energy Conversion Systems realities, looking at multi energy systems polygeneration plant layout (i.e. Industrial Estates, Buildings and Smart-Cities, District Cooling and Heating and CHP power plants).  The key challenges and activities I've dealt with have been: 

  • Support the leading of the Work Package:

    • Coordination of the team: Research Associates, PhD Candidates and MD students

    • Actively involved in the Steering Committee of the whole SMES project

    • Meeting and discussion with national agency (i.e. NEA, EMA) and partner companies (i.e. Shell, JTC)

  • Consultant for Jurong Port (JTC):

    • design and operation of a district cooling system based on CHP power plant in Jurong Port.

    • Feasibility Study, Cost Benefit Analysis, NPV and ROI evaluations

    • Optimized Layout has led to achieve 1.2M$ Savings in 10 years, 4.5 years of ROI, 15%  in Primary Energy Savings and 18% CO2 reduction. 

  • Development of an Optimal Planning Tool Software:

    • Modelling of SMES components (Engines, Chillers, Heat Exchangers, Building, Grid, Storage, others)

    • Multi-Objective function approach for accounting techno-economic optimization

    • Advanced mathematics: Hybrid Evolutionary and Simultaneous Algorithms coupled with Artificial Intelligence

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.

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

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.

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.
