Biography of Prof Dennis Y.C. Leung

 

Prof. Dennis Y.C. Leung received his BEng (1982) and PhD (1988) from the Department of Mechanical Engineering at the University of Hong Kong.  He is now a full professor and associate head of the HKU Department of Mechanical Engineering specializing in environmental pollution control and renewable & clean energy development. He has published more than 400 articles in this area including 240+ peer reviewed top SCI journal papers.  His current h-index is 56 and total citations are more than 13000. He is one of the top 1% highly cited scientists in the world in energy field since 2010 (Essential Science Indicators) and named as a Highly Cited Researcher by Clarivate Analytics in 2017.  Prof. Leung has delivered more than 50 keynote and invited speeches in many conferences as well as public lectures. Prof. Leung received numerous awards including the Outstanding Earth Champion Hong Kong award in recognizing his contributions in protecting the environment.

 

Technical Talk on: “Bioethanol: Is it a Suitable Biofuel for Reducing the Carbon Footprint of Hong Kong”

Ethanol (normally called bioethanol) is considered to be one of the best alternative fuels and additives for spark ignition (SI) vehicles. It can also be used as an additive for compression ignition (CI) engines. Bioethanol is a renewable fuel produced from various biomass resources. In California, legislation already exists to ban the use toxic MTBE additive in gasoline and substituted by other oxygenated additives such as bioethanol. Hong Kong does not have any legislation regarding the use of biofuels in automobiles.

 

In this seminar the feasibility of introducing bioethanol blended fuel to Hong Kong is discussed. A life cycle analysis on the greenhouse gas emissions for different feedstock of bioethanol production has been conducted to reveal the real benefit of using this biofuel in Hong Kong through either import or local production. Result indicated that bioethanol produced locally from waste paper can generate real advantages to the Hong Kong environment and is more realistic in implementing in Hong Kong. There will be an insignificant cost penalty of about 2% to motorists when using E5 and E10 respectively.

Technical Seminar on Bioethanol Blended Fuel in Hong Kong

By Miss Cindy M.W. Tsang

 

Technical seminar regarding bioethanol in Hong Kong was jointly organized by the Gas & Energy Division and Department of Mechanical Engineering, University of Hong Kong on 23 February 2018. Professor Dennis Y.C. Leung, guest speaker from HKU Department of Mechanical Engineering discussed on the feasibility in utilizing renewable bioethanol fuel in Hong Kong and supported its carbon reduction by Life Cycle Analysis (LCA).

 

Bioethanol is a renewable fuel fermented from various biomass resources like surge cane and wood products. The usage of this alternative fuel and additive for spark ignition (SI) vehicles is in an increasing trend due to its clean emission and natural production base.

 

In this seminar, Professor Leung started by introducing the diverse applications and significant benefits of using biofuels comparing to fossil fuels. He then explained the environmental and economic benefits of introducing bioethanol through LCA using example of waste paper-to-landfill in Hong Kong. Considering product’s life from sourcing, transporting, processing to distributing, it was concluded that cellulosic based bioethanol would benefit Hong Kong from the climate change mitigation by reducing the Greenhouse Gas (GHG) emissions by 7532 ton per day and lessening the burden of landfill sites with daily 1922 tons waste paper.

 

The seminar was concluded with a Q&A session and a souvenir was presented by our Chairman and Deputy Chairman of Gas and Energy Division, Ir Peter Chak and Ir Eric Pang, to Professor Dennis Leung as a token of appreciation.
