end-users for production of heat( large scale)

SOURCE AND APPLICABILITY SOURCE

This baseline and monitoring methodology is based

on the following approved baseline and monitoringmethodologies and proposed new methodologies:


4/31

Sources

This methodology also refers to the latest approved versions of thefollowing tools:

Tool to calculate project or leakage CO2 emissions from fossilfuel combustion;

Tool to calculate baseline, project and/or leakage emissions fromelectricity consumption;

Tool to determine project emissions from flaring gases containing

methane; Tool for the demonstration and assessment of additionality.1For more information regarding the proposed new methodologies

and the tools

Definitions For the purpose of this methodology, the following

definitions apply: Biogas is a mixture of biogenic gases composed mainly of

methane and carbon dioxide produced from thedecomposition of waste organic matter under anaerobicconditions.

Biogas processing facility is the facility which collectsbiogas from one or several biogas producing sites,processes and upgrades the biogas for the purpose ofsupplying it to end-users.

Processed biogas is the methane rich gas obtainedfrom the processing and upgrading of biogas at thebiogas processing facility.


6/31

Waste organic matter is organic matter fromeither vegetable or animal biomass but not frommineral (fossil) sources.

Biogas producing site is the site where the biogasis generated from the decomposition of organicmatter.

Biogas producing sites are either landfills orwastewater treatment plants2


7/31

Heat generation equipment is equipment in

which fuels (e.g. processed biogas, fossil fuels,etc.) are combusted for the purpose of generatingheat. The heat is used in industrial, commercial orresidential applications for processing or heatingpurposes other than for generation of electric power ormechanical energy.


8/31

Applicability The methodology is applicable under the following

conditions:

1. The biogas is obtained from one or several existing4biogas producing site(s).

2. The biogas from the biogas producing sites waseither vented or flared prior to implementation of the

project activity.3. The processed biogas is supplied to existing end-users, which use the biogas in the heat generationequipment.

4. The heat produced by the heat generationequipment at the end-user(s) is totally used on-site.

5. Under the project activity, the end-user(s) can usefossil fuels together with processed biogas from thebiogas processing facility;

6. The existing heat generation equipment may be

modified in order to enable the use of processedbiogas;

7. The supply of processed biogas to the end-user(s)does not result in an increase in their heat

Contd.

8. The supply of processed biogas to the end-user(s)does not result in an increase in their heat generationcapacity.

9. Any transportation of biogas or processed biogasoccurs only through dedicated pipelines or by roadvehicles.

10. To avoid potential double-counting, the project

participant should ensure through a contractualagreement with the end-user(s) that the end-user(s)do not claim CERs from using the biogas through aseparate CDM project activity.

BASELINE METHODOLOGY The biogas producing site(s);

The biogas collection, pre-processing (if any) and

transport system from the biogas producing site(s) tothe biogas processing facility;

The biogas processing facility;

The processed biogas transport system from the

biogas processing facility to the end-user(s); The end-user(s).


12/31

Procedure for the baseline Step 1: Select the most plausible baseline scenario for the end-

users. Step 2: Identify technically feasible alternative scenarios for the

biogas producing sites and for the biogas processing facility.

Step 3: Eliminate baseline alternatives that do not comply withlegal or regulatory requirements. Step 4: Eliminate baseline alternatives that face prohibitive

barriers. Step 4.2: Show that the identified barriers would not prevent the

implementation of at least one of

the alternatives (except the proposed CDM project activity). Step 5: Identify the economically most attractive baseline

scenario alternative. Step 6: Demonstration of additionality


13/31

baseline emission Baseline emissions include only CO2 emissions from

fossil fuels that would be used by the end-user(s)

to produce heat in heat generation equipment(s).Baseline emissions are calculated based on thequantity of processed biogas supplied to each heatgeneration equipment, the fossil fuel type that wouldbe fired in the absence of the project, and taking intoaccount differences in the efficiency of the heatgeneration equipment in the project

boundary The project boundary is the physical, geographical

sites where methane is captured, extracted andhydrogen is produced from biogas and LPG. Theboundary also extends to other equipment consumingbiogas or methane in the same site where applicable.


21/31

Baseline CO2 generated in reactions of LPG (displaced by

methane extracted from biogas in the project scenario)as feedstock during the steam-reforming/shift-reaction;

CO2 generated in the combustion process of LPG(displaced by methane extracted from biogas in theproject scenario) as fuel to the reactors.


22/31

The composition of LPG for the purpose of baselineemission calculations.

(A) Information provided by the supplier; or

(b) Compositional analysis conducted by anindependent certified laboratory; or

(c) Product specification statement provided by the

national gas supplier of the host-country


23/31

The CO2 emissions generated in reactions of LPGduring the steam-reforming/shift-reaction isdetermined by calculating the CO2 generation

potential per mol of hydrogen produced from thebaseline feedstock LPG (RCO2/H2) and the molarquantity of hydrogen produced using methaneextracted from biogas as feedstock.


24/31

The CO2 emissions from LPG combusted, as fuel inthe reactors in the baseline (displaced by methaneextracted from biogas in the project scenario) shall be

calculated based on:

(a) The specific fuel consumption of the hydrogenproduction unit using LPG as fuel as described inparagraph 15; and

(b) The amount of hydrogen produced using methaneextracted from biogas as fuel as calculated inparagraph 16 and 17.


25/31

The specific fuel consumption of baseline process(LPG SFC ) refers to the fuel consumption pernormalvolume H2 produced if LPG is used as fuel for the

hydrogen production process. This should be based onone of the following options:

(a) Measurements during crediting period when thehydrogen plant is operated with LPG as fuel;

(b) Minimum 1 year historical data;

(c) Manufacturers specification


26/31

The molar amount of hydrogen produced frommethane extracted from biogas ( H BIO m 2, ) iscalculated as the difference between the total molar

amount of hydrogen produced ( H T m 2, ) and themolaramount of hydrogen produced from the stand-by LPG ( H LPG m 2,)


27/31

Project Activity The emissions from fossil fuels and/or electricity used for

operating the biogas purification system calculated inaccordance with the method.

Emissions from fossil fuels used to generate steam for thepurpose of regeneration of the biogas purification systemcalculated in accordance with the Tool to calculate projector leakage CO2 emissions from fossil fuel combustion.

additional chemicals or energy is used to regenerate theadsorbent or absorbent for purpose of biogas purification,contribution of the used chemicals to GHG emissionsduring the lifecycle.


28/31

Leakage If the project equipment is transferred from another

activity, or if the displaced equipment is transferred toanother activity, leakage is to be considered.


29/31

Monitoring Continuous metering of hydrogen produced by the

project activity on volumetric basis;
