BACKGROUND

In an era where the urgency of climate action is undeniable, our project capitalizes on the potential of low-concentration Coal Mine Methane (CMM), transforming it from a mere by-product of coal mining into a crucial resource for sustainable energy production. This initiative is geared not towards endorsing coal combustion but towards mitigating an inevitable GHG emission from an existing energy source. By doing so, it directly contributes to global warming mitigation efforts, aligning with international climate goals. Despite China's shift towards renewable energy, its current energy infrastructure remains substantially reliant on coal. However, the commitment to reduce coal dependency is evident from China’s cessation of overseas coal power investments and the ongoing decrease in the proportion of coal in its energy mix, marking significant steps towards reducing the country's carbon footprint.

The Urgent Need for Methane Reduction
Methane’s GHG effect is approximately 28 times greater than that of CO2, presenting a pivotal opportunity for immediate climate action. Unlike CO2, which can remain in the atmosphere for centuries, methane has a relatively short atmospheric lifespan of approximately 12 years. This characteristic makes strategic methane reduction not only feasible but also economically advantageous compared to long-term CO2 removal (CDR) strategies, which often involve amazingly high costs. Reducing methane emissions now is arguably the most effective short-term strategy to keep global temperature increases within the limits established by the Paris Agreement. Advances in clean energy technologies will further enable effective GHG management, making immediate methane action a practical and vital part of broader climate efforts.

The Major Role of Coal in Methane Emissions

In China, 48% of methane emissions are attributed to the energy sector, with a staggering 80% of these emissions emanating from coal-related activities. This underscores the significant role that coal mining plays in the nation's methane emissions profile, highlighting the critical importance of projects like ours that aim to capture and utilize CMM effectively.

SOLUTION

Low Concentration CMM Utilization Process:

Methane Extraction and Delivery

The process begins with the extraction of low concentration CMM using advanced methane extraction pumps. This initial stage is critical, as it involves the careful handling of methane to ensure safety and efficiency. The methane is then conveyed through a meticulously designed pipeline system, engineered to maintain the integrity and quality of the gas.

Power Generation Using Gas Engines

The treated CMM is then fed into specially designed gas engines. These engines are a marvel of engineering, optimized to convert low concentration methane into electrical power with high efficiency. The conversion process not only underscores the complexity of the technology but also highlights the innovative approaches to energy generation.

Waste Heat Recovery

A critical component of the process is the recovery of waste heat from the gas engines. This heat is not wasted but is instead harnessed by waste heat boilers that produce hot water. This hot water is utilized within the coal mine for various applications, showcasing the project’s commitment to maximizing energy efficiency and minimizing environmental impact.

Pre-Treatment System

Prior to its utilization, the CMM undergoes a rigorous pre-treatment process. This stage is crucial for ensuring that the methane is free from impurities and contaminants that could potentially harm the gas engines. The pre-treatment system employs cutting-edge technologies such as moisture separators and fine filters to prepare the gas for efficient combustion.

Energy Distribution and Management

The electricity generated from CMM is strategically utilized. It primarily serves the operational needs of the coal mine, enhancing the sustainability of mining operations. Surplus electricity, if any, is supplied to the Centralized State Power Grid (CSPG), illustrating the project’s integration with national energy networks. During maintenance or downtime, electricity is imported from CSPG, ensuring uninterrupted power supply and operational continuity.

IMPACT

UN Sustainable Development Goals addressed :

ENSURE HEALTHY LIVES

SDG 3
Good Health and Well-being

Supporting CMM directly enhances the health and safety of miners by preventing hazardous gas explosions and reducing the risk of respiratory diseases associated with poor air quality. Your support translates into safer working conditions, promoting the health and well-being of thousands of workers who risk their lives every day. By reducing the occurrence of methane-related accidents, we can ensure that more workers return home safely to their families.

EMPOWER COMMUNITIES

SDG 8
Decent Work and Economic Growth

CMM projects aren't just about energy; they're about empowering local communities by creating jobs and sustaining economies in mining areas. When you invest in CMM, you're supporting not just a transition to cleaner energy but also bolstering local economies. Your contribution aids in providing stable employment opportunities, enhancing the livelihoods of countless families within these communities, and ensuring continued economic growth even in traditionally coal-dependent areas.

FOSTER INNOVATION AND INFRASTRUCTURE

SDG 9
Industry, Innovation, and Infrastructure

By supporting CMM initiatives, you're backing a wave of innovation crucial for a sustainable future. These projects pioneer advanced technologies in methane capture and conversion, setting a global benchmark for clean energy innovations. Your involvement helps scale these technologies, paving the way for broader adoption and inspiring further innovations that contribute to resilient infrastructure and inclusive industrialization.

CHAMPION RESPONSIBLE CONSUMPTION

SDG 12
Responsible Consumption and Production

CMM utilization is a perfect example of turning waste into resource. This project aligns with global efforts to promote responsible consumption and production by efficiently using otherwise harmful methane emissions. Your support helps us set a standard for resource efficiency and encourages the adoption of sustainable practices that can be replicated worldwide.

COMBAT CLIMATE CHANGE

SDG 13
Climate Action

Perhaps the most compelling reason to support CMM is its direct impact on climate change. Methane, being a potent greenhouse gas, significantly accelerates global warming. By converting this methane into energy, we are preventing its release into the atmosphere, thereby contributing to the global fight against climate change. Your support means taking actionable steps towards keeping global temperature rise this century well below 2 degrees Celsius above pre-industrial levels.
