“CEFC China Energy Focus 2014:
Towards Clean Coal” released in Washington
China Leads the World in Clean Coal Utilization
Driven by the rapid
development of its labor-intensive and export-oriented
industries, China’s demand for coal-derived energy rose
tremendously. Thus, how to use coal more cleanly and
responsibly in a carbon-constrained world has become the
central concern of the Chinese government and the
industries. The Chinese government has pledged to be a
responsible international player in climate mitigation, and
given that China could be endowed with the possibility to
lead the world in low-carbon development, clean coal
utilization will be both a necessary and pressing option for
China’s future energy development.
Recognizing the prospects of
cleaner coal utilization as an urgently needed means to
balance the need for affordable fuel sources for growth and
mitigating the harmful effects associated with coal
consumption in China, the CEFC has published an English
report entitled “CEFC China Energy Focus 2014: Towards Clean
Coal”, and held a publication release at the National Press
Club in Washington D.C. on April 22, to present readers
with the latest developments, challenges as well as
opportunities for developing cleaner utilization of coal in
China. While recognizing the advancement of clean coal
technologies, this report also pays close attention to
questions pertaining to the market prospects as well as
policy factors that will affect the future direction of
clean coal development in China, such as what policies the
government has introduced to promote clean coal projects,
and how the slumping international oil price will affect the
coal-based energy sectors in China.
Several leading experts from
top organizations were in attendance to discuss the
challenges and opportunities of Chinese clean coal
technology. Among the attendees were Dr. Patrick HO
Chi-ping, Deputy Chairman and Secretary-General of China
Energy Fund Committee; Mrs. Ayaka JONES, leading China coal
analyst at the U.S. Energy Information Administration (EIA);
Professor Zeng Xingqiu, Vice Chairman of the Energy Research
Center of China Investment Association and the former
Director General of the International Cooperation Department
of China National Petroleum Corporation (CNPC); and Mr. SUN
Xiansheng, President of the CNPC Economics and Technology
Research Institute (ETRI).
By conducting interviews
with leading Chinese energy experts and translating their
views and opinions into English, this report also serves as
a gateway for western audiences to gain an in-depth
understanding of how the Chinese energy industries evaluate
and anticipate the prospects of clean coal utilization. In
doing so, it also aims to create more opportunities to
facilitate policy discourses as well as knowledge sharing
between Chinese energy industries and their foreign
counterparts.
Dr. HO Chi-ping, Patrick (何志平)
, Deputy Chairman and Secretary-General of China Energy Fund
Committee, expressed that given the necessity to rely on
coal, the only energy source which China has in abundance,
the fact that China needs an affordable energy for its
industrialization, urbanization and development, and the
international pressure to mitigate the deleterious effects
of coal consumption, China may be the only place on earth to
possess the room and opportunity to realize the potential of
developing and experimenting with the various modes of low
carbon and clean coal technologies.

Summary of Key Findings:
1.
Cleaner utilization of coal in China is usually
comprehended in a much broader sense that it not only
covers important technological aspects like carbon
mitigation, but also includes a range of other technological
issues including power plant efficiency improvement,
coal-based chemical conversions and coal preparation.
However, under the current policies, wherein the
environmental costs of energy consumption have hardly been
monetized, different opinions still exist in terms of the
effectiveness and economic feasibility of different
technological approaches of cleaner utilization of coal in
China.
2.
Divergent views exist regarding the peak coal
timing and level. The central government has set a
target to control annual coal consumption at around 4.2
billion metric tons by 2020. Yet various interviewed experts
gave different projections of the timing and the physical
volume of the peak coal demand, reflecting different views
of the economic growth, energy demand growth, and the supply
mix. Their projections range from coal peaking at 4.0
billion metric tons by as early as 2016 to coal peaking at
4.55 billion tons no earlier than 2020.
3.
The coal-fired power sector should not be the
primary sector to blame for the pervasive air pollution.
Although most of the coal consumption in China comes from
the electric power sector, their environmental performance,
however, is better than that of the industrial coal boilers,
thanks to the increasing adoption of pollution control
technologies in the power sector. Latest data has shown that
the average emissions of coal-fired power plants in China
are 1.9 g/kWh for SO2, 2.6 g/kWh for NOX,
and 0.4 g/kWh for fine particulates, which is impressive for
a developing economy.
4.
The overall efficiency of the coal-fired power
plants in China is highly competitive, even compared with
those in many developed economies, thanks to the increased
deployment of modern coal-fired power plants. By the end
of 2013, the net coal consumption per unit of electric power
output in China was 321 grams of standard coal equivalent
per kilowatt hour (gce/kWh) in low heating value (LHV),
which was close to the corresponding 306 gce/kWh in Japan
and well below the 359 gce/kWh level in the US in 2012. The
Chinese government has set a target for the average net coal
consumption of coal plants in China to be lowered further to
310 gce/kWh by 2020.
5.
Considering the high-efficiency and the economic
viability of supercritical (SC) and ultra-supercritical
(USC) units, their deployment in China is expected to
continue to increase in the near future. China is
currently running the world’s largest fleet of SC and USC
units and is expected to deploy more advanced power units to
improve the overall efficiency and reduce the net coal
consumption of its coal-reliant utility power sectors. In
2010, the total installed capacity of SC and USC units in
China exceeded 120 GW and the number of 1000 MW USC units in
operation alone had reached 62 by the end of 2013.
6.
The integrated gasification combined cycle (IGCC)
technology might offer much better environmental performance
than conventional coal power plants, but its high operating
and maintenance costs governs that a wide scale commercial
application of the technology is less likely in China, at
least for the near future. According to the latest data,
the average cost of electricity generation of an IGCC unit
in China is as high as RMB 0.8-0.9 per kilowatt hour, which
is about five times higher than the average cost of a
pulverized coal-fired power plant. Even provided with
government subsidies, the IGCC plant will still be running
at a RMB 0.3 deficit for every kWh of electricity it
generates.
7.
Coal-based chemical projects are developing at
full speed in China and are regarded as an important aspect
of clean and efficient utilization of coal. However,
their economic viability will hinge on multiple factors
including technological matureness of the coal-conversion
system (in most cases referring to the gasification
systems), feedstock prices, and the operating and managerial
experiences of the plant proprietor. Price of alternative
fuels and feedstock such as oil and natural gas are also
important factors that will influence the market performance
of coal-based chemical projects in China.
8.
Among all the sub-sectors of the coal-based
chemical industry, coal-to-synthetic-natural-gas (CSNG)
production is regarded as the most controversial and least
profitable one.
Due to the gas price level not high enough to justify the
capital and operating cost and the high delivery cost
associated with the long-distance gas transmission, the
coal-to-syngas projects were commonly regarded as the least
profitable coal-based chemical projects in China by the
interviewed experts. Although the National Energy
Administration (NEA) envisioned a 50 bcm/y production
capacity of coal-based syngas to be completed by 2020,
whether the real production capacity will reach the
designated number remains uncertain.
9.
Coal-to-liquids (CTL) is identified by the interviewed
experts as the most profitable coal-based chemical projects
in China in a high oil price scenario, considering its
relatively lower production cost and its value in providing
alternative supply sources to foreign imported oil.
According to the data collected from the interviews, the
lowest possible production cost for every ton of coal-based
liquid production in China could be as low as RMB 2,850 (or
about USD 64 per barrel), which is very competitive under a
high oil price scenario. Through technological advancement
and efficiency improvements, it is believed that the profit
margin of the coal-derived liquid products could even be
expanded further given persistent high oil prices.
10.
As for the coal-to-olefin (CTO) projects, the low fuel costs
of the stranded coal mines in Western China might be able to
secure its cost advantage over the conventional
naphtha-based olefin production routes, but how long the
cheap feedstock factor can be sustianed is uncertain.
In addition, the fast-growing CTO industry in China might
displace its own naphtha to olefins industry for the time
being. However, it might also be displaced by the expanded
olefin production capacity in North America and the Middle
East underpinned by cheap natural gas feedstock.
11.
Aside from the economic factors, water resource
availability is another key issue for modern coal chemical
projects in China. As the coal chemical projects are
usually gargantuan water consumers, how to ensure sufficient
water supply for the coal-based chemical projects and
balance their water requirement with competing water
consumers should be carefully addressed. In addition,
technological matureness of the processing systems and the
managerial experiences of the operator will also play a
critical part in determining the plants’ efficiency in water
use and waste water treatment.
12.
Carbon capture and storage (CCS) systems have been
operational in several demonstration projects in China.
Three pilot CCUS projects have been completed and put into
operation in the electric power industry in China and two
advanced carbon capture projects are under construction.
Three more projects have been planned but are still pending
final government approval. But considering their high
operating and investment costs, whether CCS projects could
be commercially viable in China will largely hinge on the
progress of policy instruments such as an effective carbon
pricing system and a mature carbon trading market.
