Bio LNG is liquified biomethane
Bio LNG (Liquified Natural Gas) is liquified biomethane and has a far lower impact on the environment than fossil fuels. This liquified biomethane is entirely made from organic waste streams, such as poultry manure. It is used for transport instead of diesel and is a sustainable transport fuel to help reach the goal of a carbon-free society.
What is Bio LNG?
Bio LNG is a liquid fuel and a product of biomethane, an environmentally friendly alternative to fossil fuels. At Green Create, we take biomethane a step further to create liquified natural gas. This upgraded biogas can be used as a replacement for diesel, making it a sustainable option. The approximate composition of Bio LNG is listed in the table below:
|Carbon Dioxide (CO2)||50 ppm|
|Hydrogen Sulphide (H2S)||1 ppm|
|Moisture content||0.1 ppm|
Our green solutions
Green Create produces biogas that we upgrade into many useful energy forms, such as Bio-Methane, Bio LNG and renewable energy. During the process of making biogas, we convert the surplus into byproducts such as organic fertilisers.
The biofuel biomethane is a unique renewable alternative to natural gas. To create this biofuel, we use mainly manure and some organic waste streams.
Bio LNG is liquified biomethane and has a far lower impact on the environment. This biofuel is completely made from organic streams.
We have the innovative capability to turn biomethane into electricity and heat. We create renewable electricity and heat in large Combine Heat and Power (CHP).
After producing the biomethane, we strip the ammonia that is released during the biomethane process from the system and transform it into ammonium sulphate.
After producing methane, there is still a product left high in nutrients. We dry this product and press it into pellets or granules thus producing organic fertiliser.
How can you use liquified natural gas?
Bio LNG can be used by products that currently use LNG and other liquid fossil fuels, such as trucks and ships. Engines that use Bio LNG as a fuel are modified versions of those that use traditional liquid fossil fuels. Bio LNG produced at the Green Create AD Plants can be collected and transported by road tankers to be used offsite at offsite facilities and fuelling stations.
How is Bio LNG made?
The biomethane we make as a replacement for natural (fossil) gas can be upgraded to Bio LNG. This is done by removing any remaining CO2 and other contaminants from the biomethane. After that, we liquefy the biomethane to create Bio LNG. Different technologies are available for the polishing and liquefaction of biomethane, depending on the size of the liquefaction plant:
- We remove the CO2 and other contaminants with a membrane system or with an amine scrubber.
- The liquefaction of the methane is performed in a cryogenic process that lowers the temperature to -155°C, while the pressure is maintained at 1-4 bar(g). This makes the energy density of Bio LNG 600 times greather than that of the biomethane gas.
