What is Renewable LNG (RLNG)
Renewable LNG or also called Bio-LNG is a renewable fuel produced from organic waste, such as agricultural residues, food waste, and sewage sludge. It is created through a process known as anaerobic digestion, which involves breaking down organic matter in the absence of oxygen to produce biogas, a mixture of methane and carbon dioxide.
The biogas is then purified to remove impurities and compressed to increase its energy density. The purified and compressed biogas is then liquefied to produce bio-LNG, which can be used as a low-carbon fuel in transportation, heating, and power generation.
Bio-LNG is considered a sustainable alternative to fossil fuels because it reduces greenhouse gas emissions by up to 90% compared to traditional fossil fuels. It also helps to reduce waste and promote the circular economy by repurposing organic waste that would otherwise end up in landfills.
What is Renewable Natural Gas
Bio-LNG is renewable natural gas that has been reduced to a liquid state, through a process of cooling.
