Application Uses
- Fuel for Power Generation: Methane is widely used in power plants and natural gas stations for generating electricity due to its high energy content.
- Industrial Fuel: Methane serves as an important fuel for industrial heating processes and as a feedstock in the production of chemicals like hydrogen.
- Natural Gas: Methane is the primary component of natural gas, used extensively for residential and commercial heating and cooking.
- Renewable Energy: Methane from organic waste (biogas) is increasingly used as a renewable energy source, reducing greenhouse gas emissions.
- Synthesis of Chemicals: Methane is used in the chemical industry to synthesize products such as methanol, formaldehyde, and acetic acid.
