en.Wedoany.com Reported - The first CCER project for low-concentration coal mine gas utilization in Shaanxi, China, recently completed its public notification period. Undertaken by the Shaanxi Coal Research Institute and located at the Binchang Dafosi Coal Mine, the project focuses on low-concentration gas below 8% and ventilation air methane. The project adopts RTO (Regenerative Thermal Oxidation) technology, destroying 7.91 million Nm³ of gas annually and achieving an annual reduction of 118,600 tonnes of carbon dioxide equivalent.

The coal mine low-concentration gas CCER project announced this time is a development activity under the greenhouse gas voluntary emission reduction mechanism. Low-concentration gas (concentration below 8%) is difficult to utilize effectively under traditional technical conditions and is often directly vented. This project converts methane in the gas into carbon dioxide through RTO regenerative thermal oxidation technology, thereby reducing the impact of the greenhouse effect. After completing the public notification, the project meets the conditions for entering the voluntary emission reduction trading market.

Currently, this CCER project is the first in Shaanxi Province to complete public notification in the field of coal mine low-concentration gas. The project destroys 7.91 million Nm³ of gas annually, corresponding to an annual reduction of 118,600 tonnes of carbon dioxide equivalent. The Shaanxi Coal Research Institute stated that the technical pathway of this project provides a replicable implementation case for the resource utilization of low-concentration gas, filling a gap in the development of related carbon assets in Shaanxi Province.

Subsequently, the project will proceed with emission reduction quantification and verification work according to the requirements of the CCER mechanism. The implementation of this project has achieved triple benefits in safety, environmental protection, and economic returns, providing a reference solution for gas management and utilization in similar coal mines nationwide.
