LNG (Liquefied Natural Gas) is generally considered cleaner than coal when it comes to power generation. LNG emits 50 to 60 percent less carbon dioxide (CO2) when combusted, compared to coal. Additionally, LNG doesn’t produce ash or particulates and significantly lower volumes of sulfur dioxide (SO2) and nitrogen oxides (NOx), which are major air pollutants. However, it's crucial to consider the entire lifecycle of both fuels, including extraction, transportation, and usage, to fully assess their environmental impact.
FAQs & Answers
- Why is LNG considered cleaner than coal? LNG emits 50 to 60 percent less carbon dioxide than coal during combustion, and produces significantly lower levels of air pollutants like sulfur dioxide and nitrogen oxides.
- Does LNG produce ash or particulates like coal? No, LNG combustion does not produce ash or particulates, unlike coal which generates ash that contributes to air pollution.
- What environmental factors should be considered when comparing LNG and coal? Besides combustion emissions, the full lifecycle impacts such as extraction, transportation, and fuel usage should be evaluated to assess the overall environmental effects.
