What is Bio LNG?
Bio LNG is biomethane from renewable sources in liquid form, obtained by liquefying gas at cryogenic temperatures (approx. -160 ºC) to reduce its volume and facilitate storage and transport.
In practice, we are talking about a fuel with the same applications as LNG in mobility, but with one key difference: its renewable origin, as it comes from the use of organic waste and by-products.
Bio LNG = liquefied biomethane that can be transported and used efficiently in applications where high energy density is required (e.g. heavy transport).
How Bio LNG is produced step by step
From organic waste to biogas (anaerobic digestion)
Certain types of waste and by-products (agricultural, industrial, sludge, organic fraction, etc.) can be treated using anaerobic digestion to generate biogas.
Upgrading: from biogas to biomethane
The biogas is purified (upgraded) to remove CO₂, water and traces, and obtain a high-purity gas (biomethane), suitable for energy uses equivalent to natural gas.
Liquefaction: biomethane at -160 ºC
Biomethane is cooled to convert it into a cryogenic liquid, as is the case with LNG, but maintaining the renewable origin of the fuel.
What it is used for: heavy transport and other applications
Heavy transport (trucks and fleets)
Bio LNG is used especially on long-distance routes, where the liquefied format offers greater autonomy and similar operation to LNG. In many cases, the practical difference compared to compressed options is precisely that: greater autonomy due to the higher energy density of liquefied fuel.
High energy demand environments
Due to its energy density and logistics, Bio LNG is also suitable for applications where liquid fuel facilitates large-scale supply and storage.
Traceability and sustainability: what to check
Renewable origin and guarantees of origin (overview)
In renewable gases, traceability matters: it is advisable to verify the origin and associated documentation (e.g. guarantees of origin frameworks and market rules that are being harmonised/updated in the EU).
Emissions measurement: why it depends on origin and chain
The actual impact (in CO₂ equivalent) depends on the type of waste, the process, logistics and how it is accounted for. Therefore, rather than promising a single figure, it is more serious to talk about methodologies, certification and traceability.
Where can you refuel with Bio LNG?
Refuelling stations and regular routes
HAM Group operates a network of more than 150 refuelling stations with Bio LNG and Bio CNG, available 24/7/365 and offering standard payment options.
To plan routes, it is best to consult the list of Bio LNG refuelling stations and check fuel availability at each location.
HAM card for professionals
If you operate a fleet, the HAM Card is designed for professional use (companies and self-employed professionals) and facilitates refuelling at stations.
Frequently asked questions about Bio LNG
Are Bio LNG and biomethane the same thing?
Can I use Bio LNG in an LNG truck?
How is it different from LNG?
How does it differ from Bio CNG?
Mainly in the format: liquefied (Bio LNG) versus compressed (Bio CNG), which usually affects range and storage.
