Study Report

Note: Preliminary drafts of MRV Methodology and Calculation Sheet are the result of the study. They have neither been officially approved, nor are guaranteed to be officially approved under the JCM/BOCM.
Description of Project/ActivityThe purpose of the Project is to reduce Green-house gas (GHG) emissions by displacing diesel fired power generation at small rice mills thorough dissemination of low-cost and easy-to-operate stirling engines that use biomass as fuel in Cambodia where rice mills largely depend on captive power generation using diesel fuel due to limited development of grid electricity.
Eligibility Criteria
  1. The technology introduced involves installation of a biomass electricity generation technology in rice mills where there was no such technology installed prior to the implementation of the project activity.
  2. The project activity shall replace fossil fuel used in a captive power plant not connected to grid.
  3. The fuel used in the project activity consists solely of renewable biomass.
  4. The technology installed under the project activity does not generate toxic substance as byproduct through processes, such as reforming of gas.
  5. Project participants are able to monitor the amount of net electricity generated by the project activity.
Reference Scenario and Project/Activity BoundaryReference scenario is electricity that would be replaced by the renewable energy unit installed under the project activity is generated by the fossil fuel based power generation system.

The project boundary includes industrial, commercial facilities consuming energy generated by the system.
Calculation Method Options
Default Values set in MethodologyBased with comparative analysis with outcomes from other research activities and CDM methodologies, the conservative default value of 0.8kgCO2/kWh is established for diesel power generation.
Monitoring MethodThe main item to be monitored is net electricity generated by the biomass power generation unit installed under the Project. It will be measured by an instrument capable of continuous measurement. Data will be aggregated monthly
GHG Emissions and its Reductions17.52tCO2/yr
Method of VerificationAccuracy of monitoring equipment will be confirmed by manufacturer’s guarantee. If the guaranteed accuracy level is within the range accepted by JCM/BOCM Manual, no calibration is required.
Environmental ImpactsA stirling engine is not expected to cause any negative impact on the environment as it does not produce any harmful substance such as tar as byproduct and it produces lower level noise and emits lower amount of NOx and SOx compared to conventional technologies.
Financial PlanThe stirling engine to be installed is expected to be priced at around 12,000 USD for 3.5kW unit. The cost will be 170,000 USD for 50kW. Micro-financing is being considered as a source of fund.
Promotion of Japanese TechnologyJapan will provide core technologies for stirling engine generator and generation control system. On the other hand, in order to minimise cost, best-mix of technologies by partnering with Chinese, Korean and Japanese manufacturers is being considered. The first batch of engines is expected to be introduced for promotion purpose in 2013 and subsequent batches will be introduced for sales in 2014. Easy operation and optimization are required for dissemination and control technologies and know-how from Japan will be introduced to achieve such goal.
Sustainable Development in Host CountryThe Project will contribute to climate change mitigation by GHG reduction through displacing fossil fuel with biomass fuel for power generation. At the same time, the Project is in line with energy policy of Cambodia as it supports low-cost energy development and rural electrification, therefore contributing to sustainable development of Cambodia.
