Sinopec's Groundbreaking Geothermal Project Connected to Power Grid
Sinopec Star Co., Ltd., a clean energy arm of China Petroleum & Chemical Corporation (HKG: 0386, 'Sinopec'), has achieved a significant milestone by connecting its geothermal power generation pilot project to the grid. This initiative represents Sinopec's inaugural venture into geothermal electricity production, which includes an innovative approach to thermoelectric helium integration.
Innovative Geothermal Power Generation
The project currently harnesses geothermal energy to generate electricity in the Guanzhong region, a location recognized for its large-scale, high-temperature geothermal capabilities. It operates by tapping into a geothermal well situated in the Baoshi Jiayuan community, which is about 3,000 meters deep and has a wellhead water temperature of approximately 102 degrees Celsius.
Project Operations and Efficiency
During the heating season, geothermal water is extracted for heating purposes while simultaneously facilitating helium extraction for low-load power generation. In contrast, the facility shifts to full-load operations for continuous power generation during the non-heating season, where helium extraction continues. This facility serves an area of 120,000 square meters and is capable of producing 700,000 kWh of electricity annually.
Strategic Importance of Helium Extraction
A notable aspect of this project is Sinopec’s focus on the extraction of helium, dubbed the 'golden gas', crucial for various applications, including aerospace, healthcare, and industrial processes. Despite China being a major manufacturing hub, the country has historically relied on imports for helium. The new project hopes to change this landscape by producing helium sourced from geothermal wells.
Helium Resource Richness
Located in the Weihe Basin, the area is abundant with water-soluble helium alongside other significant gas resources. Experts from Sinopec have recorded remarkably high helium concentrations within the geothermal wells. Through advanced techniques involving membrane separation and variable pressure adsorption, Sinopec Star has successfully achieved a helium purity level of 99.99% at the Xianyang site, paving the way for large-scale production solutions.
Leading the Charge in Geothermal Development
Sinopec has solidified its position as a frontrunner in geothermal energy advances within China, boasting over 100 million square meters of geothermal heating capacity installed across 72 cities. Its ongoing projects, such as the one in the Xiong'an New Area, have even garnered recognition from international agencies as exemplary models in renewable energy.
