Assoc. Prof. Dr. Rafiziana Md. Kasmani

Department of Energy Engineering, Faculty of Chemical and Energy Engineering, Universiti Teknologi Malaysia (UTM), Malaysia.

Rafiziana is a senior lecturer at the Department of Energy Engineering, Faculty of Chemical and Energy Engineering, Universiti Teknologi Malaysia (UTM). Completed her PhD in 2009 at University of Leeds, UK, specializing in vented explosions.

The main research focus is on fire engineering, gas and dust explosion by studying a series of methodologies for classifying flame acceleration and potential detonation hazard in chemical process industrial, including mixtures of different sensitivity. She managed to secure research grant with a total of more than RM2 million to date and published over 100 papers at the international and national levels in refereed journals and proceedings. For supervision, 5 PhD and more than 10 Masters has successfully graduated under her supervision with total current students of 2 PhD and 1 Masters. She also secured AUN-SEED Short-term Research Program in Japan (SRJP) JFY 2015 in University of Tokyo and a recipient of Fulbright Malaysian Scholar Program for 2017/2018 in University of Maryland, USA for six (6) month and selected as one of the recipient of Erasmus+ Mobility Staff Program in 2017 in Universidad Polit├ęcnica de Madrid (UPM).

Through her experiences and expertise in Fire and Explosion engineering, Rafiziana has the opportunity to participate as a speaker in a variety of related courses, conferences and workshops and was invited as a keynote speaker at several international conference platforms. She also frequently served as technical reviewer to prestige international journals that has allowed for a broad resource base on which to build her career as educator and researcher.

Risk Evaluation of Hydrogen Storage and Transportation as Energy Carrier

Safe practices in the production, storage, distribution, and use of hydrogen are essential for the widespread acceptance of hydrogen and fuel cell technologies as transition to enhanced global sustainable development by facilitating the safe introduction and commercialisation of hydrogen as an energy carrier of the future. A catastrophic failure in any hydrogen project could damage public perception of hydrogen and fuel cells, focusing on the risk of hydrogen leakage on the storage vessels and related devices, specifically the compressor and the dispenser. In this work, different cases of hydrogen leakage and combustion are evaluated for high pressure storage vessels with respect to different application situations, based on the prototype buggy car developed by Universiti Kebangsaan Malaysia (UKM) and global layout of hydrogen refuelling stations. The investigation covered the hydrogen refuelling station dispensing system, including bulk hydrogen storage, compressors, buffer storage and dispensers; and Fuel Cell Energy Vehicles (FCEVs) storage used in ground support vehicles (e.g., cars and buses). Highlight on the common safety gaps and vulnerabilities in FCEVs and safety separation distance in refuelling station system are elaborated, considering the prescriptive and performance based approach in accordance with consensus international regulation, codes and standard (RCS). Based on these elements and an accidentology, a risk analysis has been conducted in order to identify all accidental situations that could occur. These preliminary outcomes of this study may be useful as a prerequisite input for the creation of standards and regulation related to the hydrogen-based technology, additional to National Automotive Policy (NAP) 2014. The safety vulnerabilities separation distance available between RCSs, the mitigation of associated risks, and assurances that effective safety communications plans are in place are also explored.
