CNG: Fuel of the future

There is no denying the fact that the world’s fossil fuel reserves are being depleted. Accordingly, many businesses that are aiming to reduce their carbon footprints and become eco-friendly have adopted alternative sources of energy in place of conventional fuels.

One of those energy sources is compressed natural gas (CNG), a product which is gaining popularity on a global scale due to its clean-burning properties.

“In addition to its environmental friendliness, reliable supply and consistent availability, CNG pricing is more stable than that of conventional heavy fuels, eliminating the uncertainty associated with monthly price adjustments,” says Stephen Rothman, CEO of CNG Holdings. He says the latter aspect allows businesses to better plan budgets and control operating costs for vehicle eets.

As a division of CNG Holdings, NGV Gas is committed to promoting the use of compressed natural gas as an alternative fuel for a variety of vehicles. According to Rothman, petrol driven vehicles are easily converted to run on CNG using kits approved by OEMs and imported by CNG Technology – a division of CNG Holdings.

He adds that diesel engines typically used in buses and large commercial vehicles can also be modi ed to run on a mix of CNG and diesel, the ratio being controlled by an ECU which varies depending on driving habits and/or engine torque demand. The amount of diesel replaced by gas will vary between 40% and 60%.

The company has converted vehicles for – or supplies CNG to – a number of major transport fleets, including those operated by Metrobus, Eqstra, Fidelity, G4S, Coca-Cola and the City of Johannesburg. Additionally, more than 700 taxis have been made CNG friendly.

Many NGV Gas customers have had lling stations installed on their premises, apart from being able to fill up at any NGV gas station in the Gauteng region, where the company’s operations are concentrated.

“Over the last decade, the average cost per litre of both petrol and diesel has risen significantly,” says Rothman. “CNG can offer a saving of between 25% and 40% on fuel costs compared with conventional fuels, dependent on the type of vehicle.”

Apart from the gas’ environmentally friendly nature, tanks used to store the fuel are stronger than those used for diesel, reducing the likelihood of accidental leakage. Additionally, should CNG be accidently released, it disperses quickly in the air instead of onto the ground, reducing the risk of fire as well as soil contamination.

Rothman says CNG Gas is actively sourcing new solutions for the trucking industry, and will be in a position to offer customers a variety of state of the art products within a few months.
