Jharkhand IIT-ISM Students Develop Eco-Friendly Fuel by Enriching Coal Bed Methane with Hydrogen
In a groundbreaking initiative, second-year students from the Chemical Engineering department at the Indian Institute of Technology (IIT) – Indian School of Mines (ISM) Dhanbad have developed an innovative technology that transforms coal bed methane, a potent greenhouse gas, into an environmentally friendly fuel. This new fuel, named Hydrogen Enriched Coal Bed Methane (H-CBM), can be utilized directly in compressed natural gas (CNG) vehicles without requiring any modifications.
Understanding Coal Bed Methane
Coal bed methane (CBM) is a natural gas that is found in coal seams. It is released during the coal mining process and poses significant environmental risks, being approximately 25 times more harmful than carbon dioxide in terms of its greenhouse gas effect. The release of CBM contributes to global warming and environmental pollution, making its management a critical concern for environmental scientists and engineers alike.
The Development of H-CBM
The students involved in this project—Kailash Krishna, Nitin Gaur, and Devashish Das—worked under the guidance of Assistant Professor Ejaz Ahmed, with support from Professor Alok Das of the Mechanical Engineering Department. Their research focused on purifying coal bed methane to produce pure methane. The process involves cracking a portion of the methane to separate hydrogen and carbon nanotubes.
Process Overview
The process of creating H-CBM can be summarized in the following steps:
- Purification: The initial step involves purifying coal bed methane to extract pure methane.
- Cracking: A portion of the purified methane is then cracked, resulting in the production of hydrogen and carbon nanotubes.
- Enrichment: The remaining methane is enriched with the extracted hydrogen, resulting in H-CBM.
Benefits of H-CBM
The development of H-CBM presents numerous advantages:
- Environmental Impact: Capturing and utilizing coal bed methane can significantly reduce environmental pollution. According to Professor Ahmed, capturing just 1 kilogram of coal bed methane is equivalent to reducing pollution by 25 kilograms of carbon dioxide.
- Fuel Efficiency: Hydrogen has a higher calorific value than CNG, which means that vehicles powered by H-CBM can achieve better fuel efficiency.
- Cost-Effective Hydrogen Production: The process of producing hydrogen alongside carbon nanotubes makes the cost of hydrogen virtually zero, as the market price of carbon nanotubes can reach up to Rs 500,000 per kilogram.
Applications of Carbon Nanotubes
During the hydrogen extraction process, carbon nanotubes are produced as a byproduct. These nanotubes are known for their high strength and are used in various applications, including:
- Bulletproof Jackets: Due to their strength and lightweight properties, carbon nanotubes are utilized in the production of bulletproof materials.
- Steel Industry: Carbon nanotubes are also employed in the steel industry to enhance the strength and durability of steel products.
Future Implications
The research conducted by these IIT-ISM students is poised to make a significant impact in the field of green mining and sustainable energy. The ability to convert a harmful greenhouse gas into a usable fuel source not only addresses environmental concerns but also contributes to the development of cleaner energy alternatives.
Student Insights
Devashish Das, one of the students involved in the research, highlighted the importance of this initiative. He noted that while CNG cars emit less carbon dioxide compared to petrol and diesel vehicles, they do not completely eliminate emissions. The development of hydrogen fuel from coal bed methane is a step towards reducing the overall carbon footprint of the transportation sector.
Conclusion
The innovative work by the students of IIT-ISM Dhanbad showcases the potential of academic research in addressing real-world environmental challenges. By transforming coal bed methane into H-CBM, they are not only providing a solution to a pressing environmental issue but also paving the way for more sustainable fuel alternatives in the future.
