Research on the development mode of clean energy heating and its carbon emission reduction benefit in Beijing

Abstract

Beijing has pledged to peak carbon dioxide emission by 2020. Promoting clean energy heating in winter is an important measure to reduce carbon emission, and Beijing government has given large policy support for clean energy heating. In this paper, the clean energy heating policy has been simulated and its carbon emission reduction benefit has been studied. Various typical clean energy heating technologies suitable for Beijing are presented and evaluated in the aspects of initial investment cost and running cost. Energy technology model is adopted to conduct a comprehensive optimization for heating technology path between 2015-2020 for Beijing under benchmark and policy scenarios. Model optimization results show that, comparing with benchmark scenario, the carbon emission reduction will reach 25 million tons for policy scenario. Under policy scenario, in 2020, the proportion of natural gas heating will reach 86%, while the electric heating will account 9%, among which air-source heat pump occupies 86%. Power consumption for electric heating will reach 4.9 billion kWh, and gas consumption for gas heating will reach 13.3 billion cubic meters.
