CNG – a cost-effective solution for a greener future

CNG (compressed natural gas) is natural gas that is compressed to 1% of its original volume before its use (refuel of a car). CNG fuel evaporates rapidly in the air, therefore, it does not present a risk of explosion in the event of a leak, and it has a higher ignition temperature than petrol and diesel, thus reducing the risk of accidental ignition.

CNG is the cleanest combustible alternative fuel because its combustion produces significantly less emissions that are harmful to nature. CNG fuel is not only environmentally friendly but also economically advantageous; its use saves up to 40-60% on fuel costs compared to the petrol and diesel; moreover, the operation of CNG car is cheaper, CNG engine runs much quieter and more gently, no sound pollution is caused to the environment, and it also protects the car engine (suitable for public service providers in populated areas).

CNG for business – reduced transport cost, improved efficiency and environmental friendliness

Latvijas Gāze offers to build a private CNG fuelling station in the territory of a company. A private fuelling station will be a convenient and profitable solution for companies that already use or plan to buy CNG cars, lorries, or buses. Thanks to the low price of CNG compared to other fuels, the money invested in new vehicles will pay off quickly. Since 2020, the business energy efficiency programme of the development financial institution Altum has provided funding for the transition to more environmentally friendly vehicles, including CNG cars, and for the installation of local CNG fuelling stations on the territory of a company.

Refuelling

In Latvia, as in other European countries, both public and private CNG filling infrastructure is under development. With the development of natural gas infrastructure and technologies, private fuelling stations can be built anywhere in Latvia, not only in areas with a gas supply network. If the company is located next to the gas supply network; the fuelling station can be connected to a common network, but in the absence of such a possibility, it is possible to build a private fuelling station and supply liquefied natural gas.

Private Refuelling ECONOMIC


Individual natural gas compression equipment is ideal for low consumption and will be suitable for both households and small businesses with one to three CNG cars. Refuelling of one car can take 1-4 hours, depending on the installed capacity and equipment. ‘Economical’ refuelling can be commenced and used safely even at night because after refuelling the car's tank, the CNG station will automatically stop working. Installing individual natural gas compression equipment is simple, as they can even be added to standard household natural gas inlets.

Private Refuelling FAST

Fast CNG refuelling is as fast and convenient as refuelling with conventional fuels. By building a private CNG fuelling station in its territory, a company with a large fleet can significantly reduce fuel costs (the average CNG consumption of a passenger car per 100 km varies around 3-6 kg, depending on the model, while for cargo minibuses – from 9-12 kg), as well as perform a more accurate fuel consumption calculations while taking care of the environment.

Public refuelling

The network of fuelling stations continues to develop and expand: in Europe, natural gas and biomethane refuelling infrastructure is being developed in parallel, because biomethane has the potential to significantly green the supply and use of natural gas without fundamental improvements in either natural gas transmission or distribution (CNG fuelling stations in Europe). Currently, 6 CNG fuelling stations are publicly available in Latvia, but by the end of 2021, they will reach the number of 10.

CNG cars

CNG transport is widely used as it can be used in both urban and interurban traffic, significantly reducing environmental pollution and noise levels. The most common compressed natural gas cars use a dual-fuel engine, powered by both gas and petrol. When the natural gas runs out, the car automatically uses petrol. The CNG system in the cars is already built during the production process at the factories, so there is no reason to believe that it could be dangerous in any way. CNG cars, like other cars, are tested before operation, the gas cylinders are tested in different temperature, impact, and other conditions.
