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.

Report 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.
