Hydro power: Pico and Micro Hydropower Systems

Objective
Mitigation

Pico & Micro Hydropower System: Low-Cost Hydroelectric Generator

The “Micro Hydropower System” developed by Nakayama Iron Works Ltd., is a type of hydroelectric system that can produce a few kW to 1 MW of electricity. Until now, the company has installed hydropower plants with a maximum capacity of 49.9kW, and they are now working on a project with a maximum capacity of 420kW. The technology can produce electricity using small streams as main resource for power generation.

Development of energy audit and reporting guidelines for calculation of the emission factors (EF) for fossil fuel power plants

Eligibility Criteria

E1

The request has a clear and positive benefit to the requesting country in mitigating, or adapting to the negative effect of, climate change.
Yes
The overall objective of the request is to develop a guideline for audit and calculation of the emission factors (EF) of fossil fuel thermal power plants to enhance quality of GHG inventory activities in energy sector. The request has direct link to the MRV implementation of power sector for NDC implementation.

E2

The request is in line with national strategies and plans.
Yes
Yes, the energy sector will be the important role of the mitigation targets. Regarding the Decision of Prime Minister for national inventory of GHG approved in 2012, MOIT has been requested to implement the GHG inventory for energy sector and annually making the report of GHG emission to MONRE. Hence the request is line with national strategies, and it becomes important input national communication and Biannual Update report to UNFCCC.

E3

The request enhances endogenous capacities.
Yes
The request will enhance the audit and reporting capacity of the personnel’s of the fossil fuel based thermal plants and relevant government agencies with a focus on MOIT and MONRE. The request has also identified the key stakeholders and their roles to support the implementation of the technical assistance. These stakeholders are various endogenous departments/bodies including ministries and institutes who will get benefitted in terms of capacity enhancement in due course of the technical assistance.

E4

Processes are placed in the requesting country to monitor and evaluate any support provided.
Yes
The request made and signed by NDE confirms the same.
Prioritisation Criteria

P1

The request is aligned to the CTCN’s existing Programme of Work.
Yes
The request includes data survey and walk through audits of the thermal power plants followed by scientific methodologies would be applied to identify the baseline emission. The request will also enhance the capacity of the relevant stakeholders.

P2

The request is aligned to the key themes of the Technology Framework of the Paris Agreement.
Yes
Though the request has shown some level of readiness in term of the existing data and process for estimating electricity grid emission factor including the emission factors for the thermal power plant, it lacks the details on the combustion efficiency to report the sectoral emission on a larger scale for NDC assessment purpose. While the Emission Factor will be specific to Viet Nam, the approach adopted for estimating it and to undertake the Energy Efficiency audit has large potential for replication at regional level. The study will apply the methodology for EF calculation in 2 plants on pilot basis which may be replicated for all the he thermal power plants in Viet Nam.

P3

The request is submitted by LDCs or SIDS or by a country that has not received CTCN technical assistance in the last 5 years, taking into account regional balance.
No
The request does not demonstrate any such collaboration directly. However, it has a large potential for collaboration with other countries in the region serving as knowledge exchange or demonstration of the approach to undertake the EE audits and EF estimation for thermal power plants.

P4

The request contributes to the CTCN’s portfolio balance between mitigation and adaptation.
No
The request has not stated further leveraging of public or private financing.

P5

The request has the potential to contribute to systems transformations (nationally, regionally, and/or internationally).
Yes
The request will lead to the estimation of emission factors that will become the basis of basis for
Determining the contribution to reduce greenhouse gas emissions from economical and efficient use of energy and developing new energy, renewable energy in Vietnam.

P6

The request is part of multi-country approach to allow regional bundling of requests to promote collaboration among stakeholders, including between countries (South-South, bilateral, or multilateral cooperation).
Yes
The energy audit in power plant will lead to energy and cost saving in thermal power plants leading to employment opportunities with gender and youth inclusion.

Hydro power: Micro hydropower system (ultra-low head)

Objective
Mitigation

STREAM: A Micro Hydropower System

STREAM Micro hydropower system, a run-of-river micro-hydropower generating system, can generate electricity extremely well in ultra-low head situations. Because it is so compact and easy to install, it is a good match for areas of de-centralized power generation. Common installations for its use include; agricultural irrigation canals, waterways with regulated water discharge, water treatment plants, and power plants.

Fats/Oil/Grease treatment from wastewater: FOG-green Power Generation System

Objective
Mitigation

Fats/Oil/Grease Separation and Reforming Technology for Power Generation

wastewater derived from daily preparation and consumption of foods contains a lot of fats, oils and grease (FOG). FOG has been increasing proportionally by the world population growth and it has caused a serious

pollution on rivers and seas.

FOG normally exists as small lumps on a surface of wastewater. In general, 60 tons of wastewater are required to purify a 200ml cup of FOG.

TBM Co., Ltd. has two innovative techniques to reuse FOG:

Biofuel: Rural Energy Supply with Jatropha

Objective
Mitigation

Boosting the Rural Energy Supply with Jatropha

Nippon Biodiesel Fuel Co., Ltd. (NBF) has developed a technology that helps to produce, supply and use renewable energy to replace fossil fuel in remote areas that have little to no energy access. It allows for local consumption and production of energy within rural or remote areas. Providing local residents improved access to affordable energy, this technology also allows them to take part in being producers of energy source.

 

Bioethanol energy and fertilizer (agriculture): Ethanol Production through Yeast Fermentation

Objective
Mitigation

Production of Bio-Ethanol: Alternative Fuel & Beverage Additive

In a fermentation process, yeast is used to convert sugar into alcohol (ethanol). This process has been used in Japanese sake making for many centuries in Japan. Biomaterial in Tokyo Co., Ltd. (bits) has a lot of experience in the production of bio-ethanol using yeast. The company has proposed special strains of yeast to be used in the production of bio-ethanol that is safe to consume as a beverage additive or to use as an alternative fuel.
