Summary of "Mongolia Improved Space Heating Stoves for Ulaanbaatar"

Core Content

This document outlines the ESMAP (Energy Sector Management Assistance Programme) initiative to improve space heating stoves in Ulaanbaatar, Mongolia, focusing on the 1999-2000 project. The report details the technical, social, and environmental aspects of the project, including the design of improved stoves, the impact on air pollution, and the strategies for dissemination and sustainability.

Main Objectives

• Assess the current heating situation in Ulaanbaatar, particularly in the ger districts, where traditional stoves are used.
• Design and test improved stoves and retrofit kits to enhance efficiency and reduce emissions.
• Develop dissemination strategies for improved stoves, including financial mechanisms, training programs, and market approaches.
• Prepare a pluri-annual program for the widespread adoption of improved stoves, supported by the Global Environmental Facility (GEF).

Key Findings

• Ulaanbaatar is the coldest capital city in the world, with 70,000 gers housing 300,000 residents.
• Coal burning in traditional stoves is a major source of air pollution and health risks, especially in ger districts.
• Traditional stoves are home-made, leading to inconsistent quality and low efficiency.
• Improved stoves like the G2-2000 can reduce coal consumption by 30-40% and lower CO2 emissions.
• Fuel costs for ger households are significantly higher than for apartment dwellers, with annual expenditures up to 4,000 tugriks per m².
• Air pollution is not only due to stoves but also central heating plants, vehicles, and small boilers.
• Indoor air pollution from coal dust and smoke is a direct health hazard, especially for women, children, and the elderly.
• Stove improvements can be implemented quickly using inexpensive materials, and households can recover costs in one season.

Key Features for Project Success

• Institutional participation: Involving stakeholders, including religious representatives, NGOs, and local authorities.
• Financial intermediation: Providing credit and package deals (stoves + coal) to make improvements affordable.
• Market approach: Promoting improved stoves and retrofit kits through energy service providers.
• Technical expertise: Ensuring quality control, cost reduction, and efficiency improvements.
• Environmental health impact assessment: Evaluating the health benefits of improved stoves and air quality improvements.

Dissemination Strategies

• Free training sessions in ger districts to educate users on self-improvement techniques.
• Retrofit kits designed to be installed by technicians and affordable for low-income households.
• Package deals for improved stoves and coal to encourage adoption.
• Public-private partnerships involving ESCOs (Energy Service Companies), microcredit institutions, and local producers.

Scale-Up and Replication Potential

• The household heating issue is not unique to Mongolia and is common in Central Asian countries.
• The project has tested and refined methodologies for household surveys, stove analysis, coal stove testing, and private sector training.
• Stove improvements can reduce fuel costs by one-third and air pollution, benefiting poor households, public health, and the environment.
• The project also promotes professional knowledge and local small businesses.

Limitations and Challenges

• Stove replacement is slow due to the long lifespan of traditional stoves and high cost of improved models.
• Fuel consumption remains high due to social habits and lack of alternative fuels.
• Air pollution peaks during refueling times and heavy traffic require complementary measures such as changing coal delivery methods.
• Technical and financial support is needed to ensure widespread adoption and long-term sustainability.

Next Steps

• Promote self-made improvements using inexpensive materials.
• Encourage coal deliveries in smaller quantities to reduce pollution peaks.
• Develop and implement a pluri-annual GEF program for widespread dissemination.
• Continue training for ESCOs, technicians, and stove producers.
• Ensure institutional support through stove certification and air pollution management.

Conclusion

The ESMAP project in Ulaanbaatar successfully developed and tested improved stoves and retrofit kits, leading to significant reductions in coal consumption and emissions. It also laid the groundwork for a sustainable dissemination program, emphasizing stakeholder participation, financial accessibility, and technical support. The project highlights the importance of energy efficiency in poverty reduction and environmental protection, and its methodologies are replicable in other Central Asian countries.
