|
a) Please ensure that detailed contact information for all organizations mentioned is reported
under section A.2 above.
B. Governmental acceptance, approval or endorsement
Bearing in mind that all activities implemented jointly under this pilot phase require prior acceptance,
approval or endorsement by the Governments of the Parties participating in these activities, which shall be
shown as follows:
- a. In the case of joint reporting, the report is submitted by the designated national authority of
one participating Party with the concurrence of all other participating Parties as evidenced by attached
letters issued by the relevant national authorities;
- In the case of separate reporting, the reports are submitted separately by the designated
national authority of each and every participating Party. Information will only be compiled once reports
have been received from all participating Parties.
1) For the activity:
* This is the first report. Covering the activities at AIJ project feasibility study and AIJ project design
stage, and copies of letters of endorsement by each designated national authority of Parties are attached.
Describe:
|
The MOU to consider CFBC/CHP Project in Shangqiu Thermal Power Plant as Sino-Norway cooperation in
AIJ Pilot Phase under UNFCCC, has been signed by Chinese and Norwegian government. Then both
governments have signed the formal cooperation document.
|
2) This report is a joint report:
- Yes, forward copy of agreement/endorsement by the designated national authorities involved
-
Error! Bookmark not defined.No, this is a separate report. The reports are submitted
separately by the designated national authority of each and every participating party.
|
3) General short comment by the government(s) if applicable:
This is the first project report. The system boundary design and basic technical data were preliminary
checked by Chinese experts. The environmental benefits, methodological and technical issues were addressed
on the project specific basis. On the other hand, due to insufficient data
availability and lack of uniformed methodology guidelines the results
reported here are subject to modification. Hopefully with the further progress of the project
activities, more monitoring information on emissions and experiences in methodologies will be built up, and
therefore the subsequent reports could be updated later on.
C. Compatibility with and supportiveness of national economic development and Socio-economic and
environment priorities and strategies
|
Describe (to the extent possible) how the activity is compatible with and supportive of national
economic development and Socio-economic and environment priorities and strategies
|
|
Development of CFBC and CHP have been listed in the national key technology renovation plan for
energy saving in industrial and electric power sectors, and is also the important measure to be
taken by the national urban sustainable development strategy and Chinafs Agenda 21. So this
CFBC/CHP AIJ project must be supportive of the national environment and development strategies and
priorities in China.
Given the advantage of CHP in socio-economic and environmental benefits, the national district
heating development planning pay high attention to CHP development by installing 2 GW of new CHP
capacity annually up to 2000. Therefore as mentioned in the project final document, there are large
market potentials for small CFBC/CHP project development. And promotion of CHP development by the
AIJ project will certainly contribute to the sustainable development of urban district heating in
China.
|
D. Benefits derived from the activities implemented jointly project
Whenever possible, quantitative information should be provided. Failing that, a qualitative description
should be given. If quantitative information becomes available, it could be submitted using the update(s).
(If the amount of quantitative information is too large, the source could be indicated.)

Please fill in
|
|
Describe environmental benefits in detail:
|
Emission of SOx, NOx, soot and smoke are reduced by the CFBC technology and the reduction of fuel
consumption.
The reverse osmosis desalination device is planned to be equipped with this project for
pre-desalination of the distributed water. This device is disseminated widely in China, its
application will greatly lengthen the regenera-tion circulating period of the traditional
ion-exchange device, and decrease the loss of distributed water. At the same time, it decreases the
discharge of acid and alkali.
|
|
Do quantitative data exist for evaluation of environmental benefits?
|
Yes.
The environmental protection measures will be underta-ken in the power plant under the
environmental quantity standard and regulation, as following:
1. A 120m high stack with 3m diameter of outlet will be built, in order to mitigate the impact of
flue gas emitted on the surrounding atmosphere environment.
2. The SO2 emission could be reduced effectively by the better performance of
de-SO2 at rate over 85% in-furnace of CFBC boiler. It is estimated that the maximum
daily averaged surface SO2 concentration is around 0.0266 mg/m3, which is
17.73% of the national standard value.
3. A effective dust and TSP removing system with efficiency up to 95-96%, will be installed in this
project.
It is estimated that the maximum daily averaged surface dust concentration is around
0.00236mg/m3, which is 1.57% of the grade II of the national standard value.
4. 57,000t of flyash and 10,000t of slack discharged by the thermal power plant, could be
re-utilized annually by two projects nearby: cement plant and a building material plant.
|
|
Describe social/cultural benefits in detail:
|
By providing district heat, the space heating for the household will be ensured; By providing
reliable electricity to the Aluminum Company, its productive operation could be maintained without
suffering from blackouts and shortages.
|
|
Do quantitative data exist for evaluation of social benefits?
|
No
|
|
Describe economic benefits in detail:
|
The heat supply unit cost and electricity generation unit cost are higher than that of baseline
case.
|
|
Do quantitative data exist for evaluation of economic benefits?
|
The incremental cost is up to 1.31 million US$ every year.
|
|
Description of the baseline or reference scenario, including methodologies applied:
|
(System Boundary)
In the given AIJ pilot project, the existing low efficient coal fired small industrial boilers will be
replaced by newly built Circulating Fluidized Bed Combustion (CFBC) boilers with 75t/h L 3 capacity and the
co-generation units with 12 MW L 2 capacity. They will also supply the electricity to the new industrial
users, who would otherwise purchase the electricity from local grid in absence of the AIJ project.
Therefore, the system boundary could cover the following processes and their CO2 emissions both
for baseline case and the AIJ Project: i) Electricity generation, ii) Industrial process heat supply, as
shown in the Fig. 1.
(Project Baseline)
In the AIJ pilot phase, the more direct and practical baseline approach is the project specific approach,
which is applicable to the current AIJ project as shown below.
Heat supply baseline
|
Fig. 1 The system boundary of the CFBC/CHP AIJ project in Shangqiu Thermal Power Plant
In the context of the AIJ project, about 24 small and decentralized industrial boilers, including
4t/h (3.7MW), 6.5t/h (6.0MW), and 10t/h (9.2MW) units with total 148.5 t/h (136.4MW) of the
processing heat supply capacity will be replaced, and 102 t/h (93.7MW) of newly increased
industrial heat load will be met with district heating supplied by the AIJ project. Thus, the heat
supply baseline case should be determined as i) the energy intensity for such coal fired boilers,
ii) the CO2 emission levels, in average, of those conventional industrial boilers and
space heating boilers, and iii) unit heat supply costs. Based on the technical and economic
parameters provided by The Shangqiu Thermal Power Plant for the 4T/h, 6.5T/h and 10T/h industrial
boilers, the heat supply baseline are calculated.
Electricity supply baseline
The AIJ project is planned to supply electricity to Shangqiu Aluminum Refinery Plant to meet its
load demand for the newly increased refinery capacity of 15000 T/year. Although there is local
county power plant in operation with 48 MW capacity only, it could not provide additional
electricity supply. So in absence of the CFBC/CHP AIJ pilot project, the Henan provincial power
grid, would act as electricity supply baseline.
|
|
(Results)
For heat supply baseline
i) The averaged coal intensity of heat supply for such coal fired boilers: 51.89 kgce/ GJ,
ii) The related average CO2 emission intensity: 140 kg-CO2/GJ.CO2,
and
iii) The averaged heat cost per unit heat supply: 1.98 US$/GJ.
For electricity supply baseline
Based on statistical data provided by Henan provincial electric power bureau,
i) The average coal intensity per Kwh supply : 533 gce/kwh, and
ii) The CO2 emission intensity: 1.42 kg-CO2/kwh, and
iii) Electricity supply cost: US$ 3.37 Cent/Kwh.
|
|
2) Estimated emissions with the activity:
|
|
Description of the scenario, including methodologies applied:
|
|
(AIJ project)
3L 75T/h (3L 68.9MW) of CFBC boilers and 2 L 12 MW of co-generation units at Shangqiu Thermal Power
Plant. The annual heat supply is 1.316 10K GJ/yr., and the annual electricity supply is 107.11
Gwh/yr. Based on the technical and economic specification in the project feasibility study report
and project design report, the energy efficiency, CO2 emission intensity and the unit
cost for the heat supply and electricity is calculated respectively. The special attention was

3) Calculation of GHG emission reduction with the project activities
|
TAER = TAEBaseline-TAEAIJ
TAEBaseline = (AES L SEBaseline + AHS L SHBaseline )*EF
TAEAIJ = (AESL SEAIJ+ AHSL SHAIJ )L EF
of which
TAER: total annual emission reduction,
TAEBaseline: total annual emission for baseline
TAEAIJ: total annual emission for AIJ project
AES: annual electricity supply, 107.11Gwh/yr
SEBaseline: coal intensity for unit electricity supply in baseline, 533 gce/Kwh
AHS: annual heat supply, 1,316,420 GJ/yr
SHBaseline: coal intensity for unit heat supply in baseline, 51.89 Kgce/GJ
SEAIJ: coal intensity for unit electricity supply in AIJ project, 375.5 gce/Kwh
SHAIJ: coal intensity for unit heat supply in AIJ project, 39.71 Kgce/GJ
EF: emission factor, 0.725kg-C/kgce.
So, TAEBaseline = 90.92 KT-C/year, or 333.37 KT-CO2/year,
TAEAIJ = 67.06 KT-C/year, or 245.88 KT-CO2/year, and
TAER = 23.86 KT-C/year, or 87.48 KT-CO2/year.

Note: The calculations above are based on the project operation schedule as following:
a) Remark on indirect GHG leakage: The indirect leakage could be caused by "rebound"
behavior of energy consumers. For instance, the additional energy supply with cheap cost would lead to over
energy consumption by the energy consumers, and lead to leakage of CO2 emission reduction.
However it should be stressed that there have already been the shortage of electricity supply, which
constrains the full operation of the local enterprises and the normal electricity consumption of households
by cutting down electricity service frequently. Hence the current increase of electricity supply and
consumption by the AIJ project could help the consumers to return the electricity consumption level to
their expected status. Thus such behavior is by no means of leakage. The similar explanation could be
applied to the space heating supply case.

Annex The methodology of the incremental cost of CO2 emission reduction
The incremental cost of CO2 emission reduction (ICER) caused by the AIJ project is
critical to the cost effectiveness of the environmental benefits.
The ICER is defined as life cycle averaged incremental cost for CO2 emission reduction,
as following:
ICER = 
, (1)
where
ICERij =
, (2)
is the incremental cost per unit CO2 emission reduction for the ith year and
the jth product to be caused by the AIJ project when putting into operation. Of which,
= 
, (3)
is the net CO2 emission reduction per unit of the jth product for the
ith year, which is the difference of the energy intensity per unit of the jth product between
baseline case (
) and the AIJ project (
), multiplied by CO2 emission factor for the given fuel (
), And
= 
, (4)
is the incremental cost per unit of the jth product for the ith year,
which is the difference of the unit cost of the jth product between the AIJ project (
) and baseline case (
).
N, m is the life time (year) and the number of product types for the AIJ project respectively. Here N = 20
year and m = 2 (here refer to heat and electricity), and supposing the prices of the products is the same
between baseline case and the AIJ project. And r is the discount rate at given value 10%.
It should be pointed out that given the criteria of additionality and long-term environmental benefits for
the AIJ pilot project, the incremental cost for the CO2 emission reduction should be evaluated
in the life cycle (dynamic over life time) and the marginal cost sense
