Biodiesel: When winter clogs your fuel filter

Dr Garth Cambray Cold weather can be a pain in your fuel system, especially if you use biodiesel. Here we look at how to avoid problems in cold weather. As the final long months of winter sink their teeth into Southern Africa many biodiesel users and producers in the region have discovered the irritating fact that at low temperatures biodiesel solidifies, clogging the fuel system and stopping the vehicle it was in until warmer weather thaws the fuel out.

Biofuels research strengthened at SA universities

Engela Duvenhage Research to unlock South Africa's potential of becoming a significant producer of renewable bioenergy has received a major boost with the awarding of the Senior Chair of Energy Research (CoER): Bio-fuels and other clean alternative fuels to Prof Emile van Zyl and his team at Stellenbosch University.

Racing ahead with biodiesel

Motorsport represents an arena in which new technologies can be tested in vehicles so that they can win races and attract customers. In this regard, the entry of diesel as a racing fuel in both Europe and America shows a stark divide in the level of common sense applied to marketing this versatile fuel.

Obstacles on the road to sustainable biofuels

A promising form of renewable energy could create major opportunities for developing nations to alleviate poverty and help to mitigate climate change, but could equally cause more problems than it solves, warns a report published at the end of January. The report, by the International Institute for Environment and Development, maps obstacles on the road to sustainable development of biofuels - liquid fuels produced from oily or starchy 'energy crops' such as sugarcane, corn, soybeans oil palms and jatropha trees.
