The eco-fuel with a high potential
Air pollution and greenhouse gas emissions are global problems which can be solved through the use of new, sustainable technologies to make freight shipment more ecologically compatible. With organic LNG (Liquefied Natural Gas), we can now optimally exploit the ecological advantages of methane gas, the environmentally safest fuel for internal combustion engines:
- Improved air quality by means of virtually zero emissions (70% less nitrous oxides, 99% lower air-borne soot, 90% lower methane-free HC than demanded by the Euro VINorm)
- Positive influence on global warming by the considerable reduction of CO2 emissions (about 15% lower than a comparable diesel vehicle, up to 95% lower when fuelled with organic methane)
- Enormous noise reduction for the delivery of goods in urban centers and at night
- The emission balance and the resultant CO2 footprint for the production of LNG is often underestimated. That’s because it is possible to actually achieve a virtually CO2-neutral fuel only by means of ecological production.
For this reason, Biogas Wipptal decided to develop an innovative system. Using the so-called “Sterling” process, the use of refrigerants (e.g., nitrogen) can be entirely avoided in the cooling of the methane gas to about – 164 °C. The great number of compressors needed for that are powered exclusively with ecological electricity from our own modular cogeneration plant.
Areas of use:
Fuel in heavy transport (3.5 tons and more) and in transportation by ship
In the coming years, environmentally compatible mobility will play an ever greater role throughout the country. For individual mobility, gaseous organic methane represents an ecological “bridge technology” to reduce air pollution in urban areas. But for heavy transportation, the fuel of the future – as an alternative to diesel – will be liquefied biogas (LNG) and renewable liquid organic methane. Biogas Wipptal’s project, which targets the production of 9 tons of liquefied biogas per day, is totally in keeping with that, and can make a significant contribution towards the decarbonization of the transport sector.

Climate change demands that we go new ways economically to attain sustainable operating methods and conform to climate policies. With regards to economic activities in mountainous areas, this means closing the fertilizer management cycle. The processing of agricultural wastes to produce sustainable fertilizer products as Biogas Wipptal is doing it represents a major contribution.
The resultant biogas – a sustainable, renewable source of raw materials – can also be efficiently used (with new technologies in the transportation sector and especially the area of heavy freight) as a sustainable fuel, either as liquefied biogas (LNG) or as “green” hydrogen. The enables emissions of pollutants and CO2 to be minimized, and fulfills all the requirements of climate protection. CO2 from biogas is climate-neutral since it is derived from renewable sources and not from fossil fuels.
