Biomethane CNG

Biomethane CNG

Biogas is a gas that originates from the (deliberate) anaerobic digestion of organic waste in order to yield methane (CH4). Typically, biogas is produced from agricultural and agroalimentary waste and the sludge of waste water treatment plants. It is also present at landfill facilities as a result of the natural anaerobic digestion of the organic matter it contains. The raw biogas is transformed into biomethane due to the succession of several purification steps and ultimately possesses a methane content between 95% and 99%.

Biomethane vehicle fuel, generally referred to as bio-CNG, has the same characteristics as conventional compressed natural gas vehicle fuel except that it’s produced from a 100% renewable and ecological source; a credible alternative to the fossils fuels...

It has been proven that vehicles using methane as a fuel do not emit any fine particles and have lower NOX and CO emissions as compared to gasoline and diesel engines. Most of the CNG vehicles already comply with the Euro VI standard, which will be effective as of January 1st, 2014. On the other hand, this norm will be particularly demanding for the current diesel engines, demanding a reduction in NOx and particulates emissions compared to the current Euro V standards by respectively a factor 5 and 3. This measure will thus result in a higher total cost of ownership for vehicles equipped with a diesel engine. Moreover, the optimistic future of bio-CNG is an undeniable fact as Europe engaged itself to use 10% of renewable energy in the transportation sector by the year 2020.

With Arol Energy, you have the opportunity to be accompanied from the first feasibility study to the delivery of a complete turn-key biogas upgrading and CNG production installation. We intervene typically from raw biogas flows as low as 50 Nm3/h and generally go up to 500 Nm3/h and even more.
Within the standard range our installation is based on a membrane filtration technology. At higher raw biogas flows we also provide an alternative technology based on a high performance chemical scrubbing using a specific amine solution. Both our solutions enable you to save a considerable amount of money on your vehicle fuel with a low return on investment, to limit your vehicles’ environmental impact and eventually to valorize your waste.

For the local authorities or a company fleet

Today, with a cost price of bio-CNG in the order of 0.50 € per Nm3 (anaerobic digestion of agricultural and agroalimentary waste coupled with a biogas purification installation), the local authorities can profit from the multiple advantages that bio-CNG has to offer.

In particular, local authorities can achieve a significant savings on their fuel costs, implement an effective valorization chain of their organic waste, contribute to the energy independency of their territory and reduce at the same time both their pollutant as well as their greenhouse gas emissions.

Furthermore, since 2009 the European directives require that local authorities purchase clean and energy efficient vehicles. As a result, the offer of CNG vehicles is large and encompasses light utility vehicles, small and heavy trucks, garbage trucks, city busses as well as city service vehicles such as street sweepers. In addition, the current development of LNG (Liquefied Natural Gas) will allow an even greater expansion of this dynamic sector.

Do not forget, your waste is a source of energy and cost savings.
