| JCOAL promotes to commercialize clean coal technologies developed in
Japan and transfers and disseminates these technologies to and within
countries that produce and consume coal in the Asia-Pacific region. JCOAL
also exploits and promotes coal projects based on the Kyoto Mechanism
(CDM/JI) to solve global environmental issues. |

| (1)Cultivating and Developing CDM Projects |
 |
1) Chinese coal fired power station renovation project
More than 70 percent of power stations in China use coal to generate power.
However, many of these coal-fired power stations are small- or mid-sized plants with low generation efficiency and poor pollution control measures. Japan is expected to apply its advanced plant diagnosis and improvement techniques to improve the generation efficiency power generation and the environment protection at existing coal fired power stations in China. Such a model project for a Japan-China energy conservation program was started in 2007, and its expansion to CDM projects is now being considered.
2) Qualifying fluidized bed advanced cement kiln system (FAKS)
as a CDM project
The fluidized bed advanced cement kiln system (FAKS) is new cement
production system by using the combustion properties, heat conductivity,
particle diffusion and particle enlargement specific to the fluidized bed
process. As it is possible to achieve more efficient cement production than
conventional rotary kiln system, discussions on qualifying FAKS as a CDM
project are now underway.
3) CDM projects
To apply the Kyoto Mechanisms including CDM to coal related
technologies, JCOAL carries out project-finding and surveys on global
warming issues.
What is CDM (Clean Development Mechanism)?
A developed country (investor) and a developing country (host)
work together on a CO2 reduction project. Emission reductions
credits (certified emission reductions or CER) are issued
according to how much CO2 emissions the host country has
reduced through the project. Project participants from the
investing country can share the credits, which will be used by
the investing country to achieve its own CO2 emission
reduction target.

| (2)UBC Process |
 |
| The UBC (Upgraded Brown Coal) process has been developed to upgrade
low rank coal (LRC), based on the slurry dewatering technology used in the
pretreatment process of Brown Coal Liquefaction.
Half of the world’s coal resources are so-called LRC such as lignite (brown
coal) and sub-bituminous coal. However, LRC is still consumed within local
areas only because it has high moisture, low heating value and high
propensity of spontaneous combustion. Applying the UBC process to LRC
will convert it into high grade coal with higher heating value and less
propensity of spontaneous combustion.
A joint UBC process development project between Japan and Indonesia
(2001 to 2004) with a 3 tons/day pilot plant was successfully completed as
scheduled. A large-scale demonstration project with a 600 tons/day plant
was launched in 2006. |

| (3)Quality Control for Coal Cleaning |
 |
|
From the viewpoint of coal cleaning, JCOAL has been developing coal
cleaning technologies to effectively use coal resources and control
environmental pollution, as well as expand the range of application.
1) Projects to Support the Introduction of Advanced Coal
Cleaning Systems
JCOAL helped the Cua Ong coal preparation plant in the Ha Long Bay
region, Vietnam, to improve its coal washer and waste water treatment
system. The environmental pollution control, quality management and
effective coal cleaning achieved through the project have been highly rated.
In India, a feasibility study subsidized by NEDO for a demonstration
project on VARIWAVE jigs, which were developed in Japan, has been
completed, paving the way for implementation. VARIWAVE jigs are
expected to effectively wash difficult-to-clean Indian coal and thus raise the
country's self-sufficiency in coal to meet the rapidly increasing demand.
2) Joint Research into a High Efficiency Coal Cleaning System
JCOAL has completed a joint research study in Indonesia on a high
efficiency coal cleaning system that effectively cleans different types of raw
coal to improve the cleaning efficiency, produce general coals with stable
quality and reduce the environmental burden.
With the recent rising demand for environmental
protection, coal cleaning is now able to remove from
the coal coarse particles of iron pyrite, which are one
of the sources of sulfur oxides. Thus, coal cleaning is
a promising means to help achieve environmental
protection. Subsidized by METI and commissioned
by NEDO, JCOAL carries out joint researches and
experimental projects to disseminate coal cleaning
techniques in other countries in the Asia-Pacific
region. |
