At present, in the United States and worldwide, motor vehicles are fueled almost exclusively by petroleum based gasoline (or reformulated gasoline) and diesel fuels. Since the first oil price shock in 1973, efforts have been made to seek alternative fuels to displace gasoline and diesel fuels and achieve energy and environmental benefits. Some of the alternative fuels that have been researched and used are liquefied petroleum gas (LPG), compressed natural gas (CNG), liquefied natural gas (LNG), methanol (MeOH), dimethyl ether (DME), Fischer– Tropsch diesel (FTD), hydrogen (H 2 ), ethanol (EtOH), biodiesel, and electricity. Production processes associated with gasoline, diesel, and each of these alternative fuels differ. (more…)

Oil tankers can be classified into two broad categories: crude oil tankers and product tankers. Crude oil tankers are typically large dedicated ships that carry solely crude oil. As an example, the Jahre Viking, a crude oil tanker built in 1977, is the largest floating object ever built and would require 16,500 road tanker trucks to empty its full load of cargo. Although it is theoretically possible for a crude carrier to carry petroleum products, the time and monetary costs associated with tank cleaning for such a switch would be prohibitively high so that it is rarely done these days in tanker operations. The crude carriers are classified based on their carrying capacity and suitability for a particular trade. (more…)

Natural gas is the fastest growing energy source worldwide, and its share of total energy consumption, according to the EIA, is projected to increase from 23% in 1999 to 28% in 2020. For the United States, the gas share is predicted to increase from 23.6% in 2000 to 26.5% in 2020. Gas is the cleanest of the fossil fuels, and it is the preferred choice for new electric power plants driven by gas turbines. Coal is likely to remain the lead fuel for power generation, but natural gas will expand its share considerably. (more…)

If you are not up-to-date with scientific developments, you probably have not have heard of the process of converting gas to liquids. It might not sound like it could apply to many people, but in fact it should appeal to everyone. This newer method of using our natural resources to our advantage could be the key to less reliance on foreign energy sources, resulting in lower natural gas prices. (more…)
