2 SUMMARY OF ALL R&D PROJECTS IN NGEEANN POLYTECHNIC Secured about 50 projects amounting to about $15 million in some of the following areas:- Sustainable Development Marine and Offshore Bio- Science Social Innovation Projects

3 Summary of Projects Related to Maritime Energy Systems 1 MPA (MINT) 2 A*STAR (SERC) 3 EDB (CERT) 4 NRF (CERP) Hybrid Hydrogen Oxygen Cells in Marine Applications Ethanol Production from Plant Biomass Computer-based instrumentation and monitoring system for Photovoltaic System Low-Cost Concentrating PV Systems Optimized For Singapore s Wet Tropical Climate.

4 MPA (MINT) Hybrid Hydrogen Oxygen Cell (HHO) for Marine Applications Kwee Tiaw Joo, Tan Kim Pong

5 Project Overview To study whether hydrogen and oxygen gas mixture injected directly into a diesel engine has the potential to reduce fuel consumption and engine exhaust emission. 5

6 Summary Hydrogen and oxygen mixture is produced in a HHO cell by electrolysis Two diesel engines (52kW and 2kW) are tested in a comparative study Run engine as normal without HHO Run engine again at the same load with HHO injected 6

7 Work Done Modifications to 52 kw Engine 1. Flashback arrestor 2.Simple gate valve for air inlet 7

8 Work Done 3. Installation of 24V alternator power supply to HHO generator 8

9 Main Component HHO generator 9

10 Results Fuel saving 0.7 to 5.5 % Noticeable reduction in CO (reduced by 3.6 to 20%)

11 Possible Marine Applications The existing HHO cell can be directly used onboard smaller diesel driven crafts Can be scaled up for bigger diesel engines.
