I've got no idea whether such a style can be adopted for this type of essay
Well, I don't think I have any better knowledge of that, but I'll try. First of all, I don't think yo should worry about the example because it sounds good and, typically, you can write an essay about pretty much anything--the first time you tasted mustard, if you wish--and dazzle the reader if you explain why you are talking about this one specific experience rather than any other one well enough. Well, anyway, as it is a "personal statement," it does seem as if you are making a statement (a personal one) and are being more formal rather than flamboyantly informal so I don't really see a problem here. Hopefully someone who as actually gotten out of High School will come along soon.

That was the conversation I had with my supervisor after two months into the literature survey of my final year project. He had rejected my proposal to use fermentation as the ethanol production process. Although, I knew he was right, I was bitterly disappointed. The thought of microorganisms converting wastes into fuel had taken hold of my mind. In the couple of months that followed, I gradually decided to pursue higher studies in this field - the field of Biochemical Engineering.
(Dramatic Dash, nice. Were you asking if a dramatic style is appropriate? This is definitely Drama movie intro-worthy. I like it, at any rate.)
