A pilot project to demonstrate how practical, cleaner solutions can be implemented, supporting both operational efficiency and environmental sustainability, has seen natural gas solutions provider Egoli Gas, in collaboration with compressed natural gas (CNG) solutions provider NGV Gas, convert a 2014 Volkswagen (VW) Polo from a petrol to a dual-fuel vehicle. 

The initiative demonstrates how existing vehicles can be adapted to achieve both environmental and operational gains, says Egoli Gas GM Erika Da Cruz, adding that the project forms part of the company’s broader sustainability focus and its effort to promote lower emissions transport alternatives.

Natural gas offers significant potential for the automotive industry, she says.

“Natural gas is on track to reshape the automotive industry, offering a cleaner-burning alternative source compared to conventional petrol and diesel.

“Our partnership [with NGV Gas, under the energy solutions company CNG Holdings] represents an important milestone, blending innovation with a mutual dedication to a greener Johannesburg. This project is only the beginning . . . collectively, we are forging a path toward more cost-effective and environmentally responsible transportation for South Africa's future,” says Da Cruz.

She explains that the converted VW Polo continues to perform reliably, with the CNG tank requiring refuelling “every few days” – representing a minor adjustment when considered with the environmental and cost-saving benefits presented by the conversion.

“Key advantages of CNG include reduced emissions compared with petrol and diesel, lower fuel costs, and potentially reduced engine maintenance owing to cleaner combustion,” says Da Cruz.

“As part of the Reatile Group, CNG Holdings is committed to driving sustainable innovation across our operations. Converting Egoli Gas’ fleet vehicles to CNG is a practical demonstration of how cleaner energy solutions can reduce emissions, lower operating costs, and contribute to a greener future for our cities,” says CNG Holdings CEO Josua le Roux.

With the project showing just how “cleaner, cost-effective, and environment-friendly transport is achievable”, he adds that the pilot is expected to guide a broader fleet conversion plan, with more vehicles to follow.
