Study on Integrated Utilization of Geothermal and Multi-clean Energy Heating and Cooling in Xiongan New Area, China

Abstract

Sinopec Star Co., Ltd. is China’s largest geothermal heating company with capacity of 50 million square meters. Company began to develop geothermal energy resource in Xiong County in 2009. After ten years of hard working, the total urban area has been heated by geothermal energy. In 2017, Chinese government announced the establishment of Xiongan New Area and started a high starting point for planning and high standards to build the Xiongan New Area. Aimed to build a green and livable city, clear geothermal heating will be one of the main heating methods in Xiongan New Area. This paper mainly studies the integrated utilization of geothermal energy and various clean energy heating and cooling in Xiongan New Area, clarifies the feasible use intensity of medium and deep geothermal resources, establishes a comprehensive integrated optimization model of clean energy heating and cooling, optimizes various kinds of clean energy allocation ratio combining economic evaluation and risk analysis. Ultimately a development and utilization plan of geothermal-based, integrated multiple clean energy heating and cooling is built, achieving green and low-carbon building energy supply, and improving economic efficiency significantly.
