Mongolia (Climate)

IRENA

• Mongolia has a large variation in ambient temperature over the year. • In Ulaanbaatar, the max. temperature reaches 33°C to 38°C while the minimum temperature reaches -33°C to -37°C. • Heating season in Mongolia is about eight months in most places.

• IRENA (International Renewable Energy Agency) is an intergovernmental organization. • Supports countries in their transition to a sus- tainable energy future and serves as the principal platform for international cooperation, a centre of excellence, and a repository of policy, technology, resource, and financial knowledge on renewable energy. • IRENA promotes the widespread adoption and sustainable use of all forms of renewable energy, in- cluding bioenergy, geothermal, hydropower, ocean, solar, and wind energy, in the pursuit of sustainable development, energy access, energy security, and low-carbon economic growth and prosperity - www. irena.org • Link to the report: https://www.irena.org/Pub- lications/2023/Aug/Renewable-Energy-Solu- tions-for-Heating-Systems-in-Mongolia The analysis in SHP shows that the Renewable 2050 system is the most cost-effective (Fig. 5). This leads to system cost savings of around 62% compared to the Baseline 2050 fossil fuel-based system. The savings are mainly related to the cost of externalities (local pollution and CO2 emission), which are typically not accounted for in Mongolia today. This analysis shows that the Renewable 2050 system is a feasible alternative to the Baseline fossil-based DH system in Ulaanbaatar. Furthermore, an integrated energy system analysis, including other energy sectors, could assist in identifying cross-sector synergies that could make the Renewable 2050 system yet more cost-effective.

Output of Strategic Heating Plan Today, Mongolia’s dependence on coal is high, but the scenari- os highlighted in the SHP show that it is possible to implement a green transition of the country towards 2050: • The conversion will mean a significant expansion of DH in Mongolia (Fig. 1). • The primary energy consumption can be reduced by up to 55% (Fig. 2). • The emission of CO2 can be reduced by up to 93% (Fig. 3) • The emission of SO2, NO x , and particles will be reduced by up to 99% (Fig. 4). • In 2050, the system costs will be able to be reduced by 62% compared to Baseline 2050 (Fig. 5).
