Operating motor vehicles with CNG opens up a great deal of potential for the automotive future of the combustion engine and allows the user to drive with a clean conscience. This regenerative fuel can be made available in volume and quickly, and it also relies on a pre-existing infrastructure.
But this is not all the advantages:
Thanks to the regenerative production from agricultural residual materials, food waste, manure etc., meaning all organic materials which ferment into biogas and are then refined into biomethane, there is practically an inexhaustible “raw material potential” available. Without ‘food or fuel’ problems, this opens up new perspectives and secures jobs – not just in farming.
Even the route via power-to-gas technology – a real progress topic – is suitable for the production of feedable synthetic methane.
Both production routes make biomethane the ideal partner of the energy transition.
For users of CNG vehicles, this means security in the future, the lowest CO2 values and no problems with waste gases regarding nitrogen oxide, soot particles or fine dust. And this without expensive purification technology.
revis bioenergy is a member of the CNG-Club e.V. and supports the environmentally-friendly mobility with CNG (Compressed Natural Gas) from biomethane
There are currently close to 900 public filling stations available in Germany where compressed bio fuel can be bought proportionally1 or at 100%.
According to KBA statistics, there were 93,766 approved CNG vehicles last year. Thanks to the ever improving expanded biomethane filling station network, this is thus again significantly more environmentally-friendly than with “normal” CNG.
Recently, a new initiative was announced to expand the CNG filling station network in the medium term to 2,000 stations. In addition, vehicle sales are also expected to increase and the stock of approx. 1 million CNG vehicles grow, not least due to further attractive models. The newly formed CNG Club e.V., of which revis bioenergy GmbH is a member, is campaigning to decisive bodies and intersect points for a successful future of CNG drives – whether politics, vehicle manufacturers, filling station operators or vehicle users, everyone should be under the banner of climate protection, environmental protection and sustainable mobility with renewably produced fuels.
Further growth of the biomethane proportion in fuels also depends on whether the properties of the end product actually meet the legal requirements for sustainability which are already applied to the used biomasses. Only then the legal tax relief applies. The same is true for calculating the so-called biofuel quota.
Here, revis bioenergy GmbH places a great deal of value on careful compliance with all legal requirements. This guarantees every operator of a revis bioenergy GmbH biogas or biomethane plant a flawless operation of their biogas-biomethane plant and ensures long-lasting profitability.
1 The current storage quota of biomethane corresponds to approx. 16% of the fuel proportion –even if no explicit biomethane proportion is identified at the filling station.
LNG (liquefied natural gas) is the more energy-rich “brother” of CNG. Thanks to additional deep cooling, the fuel is liquefied and can be used with an optimal relationship of volume to energy as an environmentally-friendly fuel in heavy-goods transport or in shipping. Thanks to the more flexible transportation capabilities, LNG can also be supplied to anywhere where there is no natural gas network and then transformed back into CNG.
CNG (Compressed Natural Gas) is natural gas which has been compressed under 200 bar of pressure and thus has achieved a volume reduction of around 1:200. The compressed natural gas primarily consists of CH4 and is used in personal cars as well as larger road vehicles. CNG has a significantly cleaner combustion in the engine than diesel or petrol does. This means that significantly fewer CO2 emissions are generated. The savings of harmful substances such as fine dust and nitrogen oxide is also impressive. These are often known for creating problematic air in large cities, among other things. CNG obtained from biomethane feeding stations can reach the natural gas network directly and is therefore available in Germany and all other countries linked to the natural gas network.
LNG (Liquefied Natural Gas) is also known as liquid natural gas or liquefied gas, however should not be confused with liquefied petroleum gas (LPG). Taken precisely, liquefied natural gas is usual natural gas which has been rendered into a liquid state by being cooled down to around -162°C. The volume of the cooled natural gas is reduced by around 600 times. This state makes it possible to transport the large volume of natural gas, which is often carried out by tanker ship. This advantage also of course refers to the capacity effects in the tank of the vehicle. Large volumes of renewable fuel can simply be stored in the tank of the vehicle and thus long distances can be achieved. This makes LNG more than well-suited for use in long-distance transport. If you now consider the CO2 and harmful substance emissions, you wonder why not all transport companies have already transitioned to this renewable fuel.
LPG (Liquefied Petroleum Gas) is frequently confused with the liquefied gas LNG (liquefied natural gas) as described above. It is also known as liquefied gas or car gas and is made up of a mixture of C4H10 and C3H8. This mixture is a by-product of crude oil and natural gas production and occurs originally in a gaseous state. However, it becomes liquid at normal room temperature and a pressure of max. 8 bar. This means that it can be stored very easily in tanks or cylinders. You find LPG most frequently used in cooking or heating, but also as a fuel when referred to as car gas.
H2 (Hydrogen) Hydrogen is primarily used to produce NH3 or in refineries to remove H2S from crude oil, but not as a fuel. A small proportion of the H2 required globally is produced using electrolysis. H2 is predominantly obtained using a process which releases the hydrogen from natural gas. Hydrogen could also be used as a fuel which is practically free of emissions. The only disadvantage is that the H2 must always be produced first. In the last thirty years, the automobile industry and the state have invested several billions in the development of hydrogen technology, but the technology did not get past small-batch production and prototypes.
