Biogas in the tank: A solution with sustainable LNG and CNG
In times of climate change and declining fossil resources, the search for alternative energy sources is becoming increasingly urgent. One of the promising offerings is biogas, which can be provided in various forms such as liquefied natural gas (LNG) and compressed natural gas (CNG) for the transportation sector. But what exactly are LNG and CNG, and how can they help improve sustainability? In this blog post, we take a look at these two core products.
What is biogas?
Biogas is a combustible gas produced by the anaerobic (oxygen-free) decomposition of organic material such as plant waste, manure or food residues. It consists primarily of methane and can be used directly as a fuel or to generate electricity. In modified form, it can also serve as CNG or LNG to power vehicles.
SustainableLNG: Liquefied natural gas
LNG, or Liquified 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 reaches its destination, it can be regasified and used as natural gas or used in vehicles as fuel.
Advantages of sustainable LNG:
- Lower emissions than diesel or gasoline
- 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 high pressure (about 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
Special purification processes can be used to upgrade biogas so that it reaches 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 carbon footprint of transportation and industry.
Sustainability and environment
Since 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, reducing transportation distances and costs. It can also contribute to the circular economy, as it is produced 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. Using biogas as a feedstock can further increase their sustainability. Thus, they offer a promising opportunity to make the transportation industry more sustainable and contribute to the fight against climate change.
