Afbeelding voor LNG, Bio-LNG, and Biofuel: Let’s Clear Up Confusion

LNG, Bio-LNG, Biofuel. How often do we hear these terms when speaking about fuels, energy sources and sustainability? And how often do we ask ourselves what the differences between these fuels are? Let’s admit it, the world of alternative fuels can be a bit confusing. This little blog, we hope, will clarify some confusion.

LNG: Liquid Energy

Let’s start with LNG, short for Liquefied Natural Gas. Natural gas accumulates over millions of years in natural underground reservoirs. Often, is trapped within rock formations. Transforming natural gas into LNG is a matter of temperature. At very low temperatures, typically below -160 C, natural gas shifts to its liquid state and becomes LNG fuel. Its use dates back to the 1970s and it is still considered a cleaner alternative to traditional fossil fuels because its combustion produces fewer greenhouse gas emissions. Its use is most common in transportation such as heavy-duty trucks and ships and industrial applications.

Bio-LNG: Technology at Nature’s Service

Bio-LNG is not different from LNG. The gas that composes it goes through the same liquefication process at low temperatures. The difference lies in the type of gas. Bio-LNG biogas comes from biomasses.

Simply put, organic materials like agricultural residues, organic waste, energy crops, and other biomass sources are placed in an anaerobic digester to be processed. A digester is a container with a technologically controlled atmosphere without oxygen. Here various microorganisms can digest and break down organic matter into biogas.

Bio-LNG is a renewable substitute for traditional LNG. It is considered a low-carbon or carbon-neutral fuel, as the CO2 released during its combustion is compensated for by the CO2 absorbed during the growth of the biomass used to produce it. That is one reason why at Emons Cargo 2WIN we are transforming our LNG-powered trucks into Bio-LNG.

Biofuel: Nature’s Power

Like Bio-LNG, Biofuels derive from biomasses. Plants, algae, and animal waste go through different processes to produce different kinds of biofuels. The two primary types are bioethanol and biodiesel.

Bioethanol results from the fermentation of sugars and starches in crops like corn, sugarcane, or wheat. Biodiesel comes from vegetable oils or animal fats through transesterification. Fermentation is a microorganism business that transforms sugars and starches into ethanol. Transesterification, on the other hand, is a chemical affair that turns oils or fats into biodiesel.

While biofuels do have environmental impacts, they generally lead to lower overall greenhouse gas emissions when compared to conventional alternatives.

As you can see, LNG, Bio-LNG and Biofuels are quite similar to each other. Nevertheless, there are differences in their composition, sources, production methods, and applications.
