Project Name: BioCNG Plant 5 tpd using Napier grass
Compressed Natural Gas (CNG) plants have traditionally used natural gas as their primary source. However, the growing interest in renewable energy has led to the development of biogas-based CNG plants, which utilize organic materials such as Napier grass. Napier grass, also known as elephant grass, is a fast-growing, high-yielding plant that is commonly used as fodder. It has also gained popularity as a renewable biomass source for energy production.
The Process :
In a CNG plant using Napier grass, the process begins with the anaerobic digestion of the grass. This involves breaking down the organic material in an oxygen-free environment, producing biogas, primarily composed of methane (CH₄) and carbon dioxide (CO₂). The biogas is then purified to remove impurities like CO₂, hydrogen sulfide, and water vapor, leaving behind compressed methane, which is stored as CNG.
The harvesting age of the grass is important, as young grass (harvested in 30 45 days) has a higher moisture content and solid content, which can result in a higher output of CNG.
CNG plants play a crucial role in promoting cleaner, more sustainable energy solutions. A CNG plant powered by Napier grass presents an innovative, eco-friendly solution for producing clean energy. They contribute to reducing greenhouse gas emissions and air pollution, while also providing economic advantages through the use of natural gas. As technology improves and infrastructure expands, CNG is expected to become an even more integral part of the global energy landscape making it a valuable component of the renewable energy.
This project is taking place in Nagarahalli village, Bijapur, Karnataka.
