Energy structure and Environment
Beijing municipal government has, in line with its master plan for the
urban development and long-term strategy of sustainable development,
implemented a series of effective programs to control air pollutions ever
since 1998, with tangible results so far. The major measures include
restructuring of energy mix, reduction of coal shares, especially the
direct combustion in end-use, while the use of natural gas, electricity,
new energy and renewable energy has been substantially increased. In its
bid report for the 2008 Olympic Games, the Beijing Bid Committee (supported
by the town hall) pledged that the share of nature gas in 2007 will shoot
up by 5 times; all the residential energy in downtown areas will become
clean; wind power, hot water from geothermal and solar energy, and more
sunlight through natural orientation will be in use at a maximum at the
Olympic Village and other event venues to reduce the consumption of
conventional energy; and the development and application of fuel cell,
etc. will be promoted wherever possible. For this end, the Beijing
municipal government has mapped out an action plan to restructure the
current energy mix.
present, however the annual coal consumption in Beijing is well over 26
million tons, up 50% of total energy consumption. Huge financial inputs,
feasible clean energy sources, development strategies and action plans
would be apparently necessary to substantially replace coal use with clean
energy. So, it is urgently needed to transfer some advanced international
experiences and technologies, and help channel capital investments for the
policy-makers and relevant departments of the Beijing municipal government
to overhaul the city’s energy mix. Therefore, this seminar will focus
primarily on the following three points with respect to the energy
Experiences and Lessons for Foreign Large Cities (UK)
and lessons drawn from the energy mix restructure in some large cities in
the world: how to realize the switch-over from coal-dominance to clean
energy on top, such as oil, gas and electricity, and the possible impacts
on the urban air environment.
this topic, the experiences in energy mix restructure and environment
preservation in London will be presented in particular, possibly including
1) response measures to control London’s soot pollutions in 1950s and
the effects, careful examination of its transferability to the case of
Beijing’s coal-derived soot and ash pollutions; and 2) the experiences
and prospects of efficient coal utilization in Britain.
Efficient Use of Nature Gas (USA)
An introduction to the American experiences in efficient use of natural
gas, and the technology of natural gas-based combination of cooling,
heating and power (CCHP), as well as the associated policies. The
suggestions and comments on Beijing’s efficient use of nature gas
including both technologies and policies. 2) The development and
techno-economic assessment of small and medium-sized natural gas
combustion equipment with high efficiency and low pollution. 3) The
techno-economic assessment and environmental impacts of CCHP technologies.
Efficient Use of Electricity in Large Cities (Japan)
An introduction to the Japanese experiences in efficient use of
electricity, including heat pump technology, heat and cool storage
technology and electricity pricing at peak and valley time. 2) What are
the incentives to encourage the efficient use of electricity by both
enterprises and residents in Japan, possible suggestions and comments on
efficient use of power in Beijing. 3) The development and application of
water resources (shallow-layer ground water) heat pump and its
environmental impacts (on ground water). And 4) the development and
techno-economic analysis of air heat pump at low temperature (-5ºC~-20ºC).
Status and Prospects of Space Heating in Large Cities (USA)
introduction to the current status and future development of space heating
in USA or other foreign metropolises, especially those cities sharing
similar climate with Beijing, and the government roles in the planning of
urban space heating.
Status and Reformation of Space Heating for Large Cities in Russia and
Other Transition Countries
introduction to current status and reformation process of space heating
for large cities in Russia and other transition countries, especially
district heating in those cities, possibly including pattern of space
heating, reformation of management institution, heat measuring, pricing,
and charging, etc.
and comments for Beijing’s space heating from reformation experiences in
Russia and other transition countries.
Development of New Energy and Renewable (Germany)
An introduction to the developments and encouragements of new and
renewable energy use, with the current technological and application
levels in particular. Any suggestions and comments for Beijing are welcome,
with respect to both technology and policy. 2) Solar energy and building
energy conservation, and Germany’s solar building design along with the
economic evaluation. 3) The development, application, and environmental
impacts of different geothermal and ground-heat technologies (cooling and
heating )in urban area. And 4) Economic and environmental analyses of
advanced biomass gas technologies (used to deal with agricultural wastes,
sludge and sewage form breeding farms, residues from food industry and
city sewage) in urban and suburb areas.
Clean Coal Technology and Air Pollution Control
is the world’s largest coal producer and consumer, with a lion’s share
of coal in the primary energy mix. Beijing will still see a large amount
of coal consumption even after the readjustment of its energy make-up.
According to estimates, the coal consumption in Beijing will be more or
less 20 million tons around 2005, with much of it to be put to direct
combustion. In order to reduce the coal-derived air pollutions and enhance
coal-use efficiency, the development of clean coal technologies suitable
to the case of Beijing is seen as an apparent option. For example, coal
dressing would improve coal quality and reduce ash and sulfur fractions,
coal briquette increases efficiency and reduce soot and sulfur dioxide
emissions. The replacement of oil fuel with coal slurry made by refined
coal, utilization of combustor with low NOx emission,
utilization of flue-gas scrubbers to reduce soot, SO2 and NOx
emissions. In a word, the utilization of clean coal technology will
reduce noxious emissions in the process of coal combustion, and would
prove an effective remedy to the chronic air pollutions in cities.
Coal Washing and Rational Distribution (Germany)
introduction to the shift of unwashed coal combustion to the washing and
screening process in Germany as well as the associated techno-economic and
environmental analyses. The discussion on how to guarantee or enforce the
technological process of coal washing, screening and rational distribution
in grades to satisfy the requirement of boiler’s design. An introduction
to the functions, benefits and management of coal distribution systems,
together with the current development in the world.
