KARRGREEN® multi-fuel filling stations are veritable energy hubs.

Open to all and installed close to the major road networks
KARRGREEN® filling stations distribute two alternative fuels: BioNGV (Natural Gas for Vehicles) and electricity, with an optional adaptation for the distribution of green hydrogen.

These fuels derive today from renewable production sectors such as biogas, solar, wind and hydroelectric and, in the future, will include sourcing from pyro-gasification or methanation.

Designed primarily for fuelling passenger and goods transport vehicles, the stations can also cater to passenger vehicles of the general public.

The KARRGREEN® model is based on circular economy schemes involving local authorities, institutions, farmers, cooperatives, industrialists, hauliers and all other users wishing to invest in low-carbon mobility.

They all share the same vision: respect health, reduce the carbon footprint of their activities, and preserve our planet’s resources.

Local and human values are at the core of the KARRGREEN® identity.
Getting as many local and regional economic stakeholders as possible on board is vital. By becoming a shareholder and user of
KARRGREEN® stations, you will be acting to preserve the climate and public health, while playing your part in creating lasting value throughout the land.


KARRGREEN®’s business is getting local authorities, industry, farmers, hauliers and the general public to take notice of the environmental urgency that we all need to address.

By proposing solid and sustainable solutions that are respectful of health and the environment, KARRGREEN® aims to improve our quality of life via the deployment of a network of innovative filling stations.

To promote access to low-carbon mobility KARRGREEN®  stations harbours national and international ambitions. In France, KARRGREEN® stations aims to have established 150 stations by 2024. Projects are also in development in neighbouring countries.


Ultimately, the main objective of KARRGREEN® is simple : to combat climate change by creating a community of committed users who are actively involved in changing the way things are done.

It is also about encouraging fleet users to prefer renewable fuels in order to drastically reduce CO2 emissions while remaining economically competitive, particularly in the light of European or national regulations setting certain objectives. According to the French Law on Energy Transition for Green Growth (Act of 17 August 2015), 15% of the energy used in transport must be from renewable sources by 2030. In this regard, Natural Gas for Vehicles (NGV) is identified as a mature solution for developing clean mobility.



Biomethane fuel or biogas as a vehicle fuel (BioNGV) is derived from the biogas produced by the fermentation of organic waste in a biogas plant. The biogas is purified to produce a gas made up of 97% methane, hence its name: biomethane. It is therefore turned into a Compressed Natural Gas (CNG), which is then injected into the national gas grid to be distributed at a KARRGREEN® stations. The biomethane fuel carries a certificate of origin obtained through direct relations with producers in the vicinity of the station.
In the future, it will also be possible to get the biogas from a biogas plant to the
KARRGREEN® station through transportation of the gas in liquefied form.

NB1 :

The methane is the same gas used for heating or cooking or for running industrial sites.

NB2 :

NGV should not be confused with LPG, which is a liquefied petroleum gas composed of a mixture of butane and propane, for powering LPG vehicles.

Why fuel with BioNGV ?

Road professionals such as hauliers, coach operators or tradesmen, as well as private individuals who get their fuel from a KARRGREEN® station, are assured of a 95% reduction of fine particle emissions, 80% reduction in carbon dioxide (CO2) emissions and 70% reduction in nitrogen oxide (Nox) compared to diesel vehicles. These conclusions come from the ACV study of vehicles run on NGV and BioNGV, published in September 2019 by IFP Energies Nouvelles. Furthermore, driving comfort is improved : e.g., three times less noise for a 44-tonne road tractor compared to an equivalent diesel vehicle (Acouplus / 2016 report).
Access to fuel that is inexhaustible, local, and above all sourced from the intelligent recycling of our organic waste, constitutes a lever to encourage the “greening” of mobility.

The cost per kilogram of BioNGV is 20% lower, on average, than that of a litre of diesel. In the first KARRGREEN® station in Locminé (Morbihan department), the price of a kilo of BioNGV is, for example, €0.988. This price has remained stable since the station opened in 2015.
In addition to making savings at the pump it is also possible, depending on the region, to benefit from tax incentives to amortise the investment in these vehicles. This enables long-term savings to be achieved. To compare the total cost of acquisition of a Compressed Natural Gas (CNG) vehicle, you can consult the simulator on the GRDF website : https://www.grdf.fr/institutionnel/role-transition-ecologique/rouler-propre-gnv-biognv/passer-au-gnv/tco-vehicule-diesel-gnv
The BioNGV engine is already a proven technology. A wide range of vehicles is available on the market, including HGVs, light vehicles and special vehicles such as refuse trucks and utility vans. What is more, thanks to the development of the
KARRGREEN®, network, fuelling with BioNGV is getting easier and easier. KARRGREEN® ’s deployment is a key to facilitating transport that is cleaner, less noisy, and free of the risk of fuel theft.



To achieve the goal of 100% sustainable mobility, there has to be a diversified offer of alternative fuels. To this end, KARRGREEN® stations are also equipped with charging terminals for electric vehicles. The distributed electricity comes from a “smartgrid system”, intelligently routing the power. This system produces, purchases, stores and purveys the electricity.

The distributed electricity is in part produced at the station itself, by means of a solar canopy. This is a metallic structure covered with photovoltaic panels. This electricity is stored in batteries, supplying both the station’s electricity needs and the electric vehicle charging terminals. In a KARRGREEN®, station, this means you can enjoy a break while recharging your vehicle. The stations are equipped with a water point, and in some of them there is a retail space for local produce.


KARRGREEN® stations propose electricity derived in the main from renewable energy sources. Electricity therefore, from production to its use as a fuel, enables mobility with no emissions of particulates and CO2. In addition to a reduced environmental impact, electric mobility is silent, low-maintenance and easy on the budget.
