Abstract: This article explores the option of using compressed natural gas (CNG) in automobiles as a greener alternative to other fossil fuels. The author first outlines some of the concerns about CNG, including the problems associated with hydraulic fracturing (or fracking) that is often used in the collection process for natural gas. The article goes on to explain the benefits of natural gas and the track record so far for vehicles that use CNG as an alternative form of propulsion. CNG is used primarily in cars with internal combustion engines that have a bi-fuel conversion kit installed. CNG can be environmentally cleaner than fossil fuels, as well as safer (due to quick dispersal when spilled and less likelihood of auto-ignition on hot surfaces). The author goes on to discuss the potentials for CNG use in South Africa, reporting on a Natural Gas Conference held in 2010 at which the Minister of Energy discussed evolving energy sources. However, even though the Minister’s broad support is welcomed, the actual work of introducing, testing, and implementing CNG as an alternative fuel in South Africa rests with privately owned companies, including Novo Energy and CNG Holdings (and its 3 subsidiaries). The latter is currently running trials with a variety of vehicles, including minibus taxis, buses, and passenger and light delivery vehicles.
