Biogas in the tank: a solution with sustainable LNG and CNG

In times of climate change and dwindling fossil resources, the search for alternative energy sources is becoming increasingly urgent. One of the promising options is biogas, which can be provided in various forms such as liquefied natural gas (LNG) and compressed natural gas (CNG) for the transport sector. But what exactly are LNG and CNG, and how can they contribute to improving sustainability? In this blog post, we take a look at these two core products.

What is biogas?

Biogas is a combustible gas that is produced by the anaerobic (oxygen-free) decomposition of organic material such as plant waste, liquid manure or food waste. It consists mainly of methane and can be used directly as a fuel or to generate electricity. In a modified form, it can also be used as CNG or LNG to power vehicles.

SustainableLNG: liquefied natural gas

LNG, or liquefied natural gas, is natural gas that has been cooled to very low temperatures (around -162 degrees Celsius) to turn it into a liquid state. This has the advantage that it has a much smaller volume and can therefore be transported and stored more efficiently. Once LNG has reached its destination, it can be regasified and utilised as natural gas or used as fuel in vehicles.

Advantages of sustainable LNG:

• Lower emissions than diesel or petrol
• More efficient storage and transport
• High energy density

CNG: Compressed bio natural gas

CNG, or Compressed Natural Gas, is natural gas that has been compressed to a high pressure (around 200-250 bar). It is stored in a gaseous state and used directly as a fuel for vehicles.

Advantages of sustainable CNG:

• Lower greenhouse gas emissions compared to other fossil fuels
• Cost efficiency
• Safe to use (less flammable than other fuels)

Biogas as LNG and CNG

Using special purification processes, biogas can be treated to achieve the quality of natural gas. The upgraded biogas can then be made available in the form of sustainable CNG or LNG. In this way, biogas can help to significantly reduce the CO2 footprint of transport and industry.

Sustainability and the environment

As biogas is produced from renewable resources such as waste or agricultural by-products, it is a sustainable alternative to fossil fuels. Biogas can be produced locally, thus reducing transport routes and costs. It can also contribute to the circular economy as it is obtained from waste products.

Shaping the future with bio-LNG and bio-CNG

Both bio-LNG and bio-CNG offer significant advantages in terms of efficiency and emissions. By using biogas as a feedstock, their sustainability can be further increased. They therefore offer a promising opportunity to make the transport industry more sustainable and help combat climate change.
