  • Hồ Sĩ Thoảng

Abstract

In the review perspectives and challenges for fossil fuels and biofuels in a foreseen future are presented. Although the depletion of fossil fuels (oil, gas, coal) should happen in a definite time, so far the total world reserves of these fuels continue to increase, because the incremental growth of proven reserves all the time surpasses their consumption. The opportunity of finding

new reserves of oil, gas, and coal has not yet exhausted. These tendencies have been observed generally for the world as well as for Vietnam in particular. Nevertheless, the world has to face the period of declining fossil fuels reserve, whichshould come in a certain future. On the other hand, the utilization of fossil fuels has been indicated to be the reason of global warming phenomenon caused by carbon dioxide emissions. In these circumstances, renewable types of energy have been exploited as suitable replacing alternatives for fossil fuels. This review is focused on analysis of the development of this kindof fuels, emphasizing advantages and weaknesses of different generations of biofuels. A  special attention has been dedicated to biofuels of third and fourth generations. A relevant discussion on perspectives of further orientation of biofuel development, including for Vietnam, has been done.
