A study of future energy requirements and of the potential of various energy sources (coal, oil, gas, nuclear power, hydropower and solar energy) indicates that the contribution to be made by nuclear fission, now competitive with conventional energy sources, will grow steadily over the next few decades. Whereas the amount of fuel which has to be fabricated each year for the operation of a nucle...

Currently, in the United States there is a growing gap between domestic oil production and consumption. The Department of Energy has developed a modeling tool (known as VISION) that projects future consumption by the transportation sector through the year 2050. This paper uses the VISION model to show that an energy savings of 3.8 billion gallons per year can be achieved with a 2.5% improvement...

In order to clamp down on the illegal use of fishing boat fuel A (FBFA) and to reduce exhaust emissions in Taiwan, the residue from a desulfurization unit (RDS) and pyrolysis fuel oil (PFO) were added into FBFA with the ratio of 0.5% to form two new blended fuels (RDS0.5 and PFO0.5). The appearances of fuels from dark to light are RDS0.5, PFO0.5, and FBFA. The two new fuels have higher viscosit...

Natural gas is lauded as a cleaner-burning fuel than either coal or oil, but getting the fuel out of the ground can be a dirty process, especially given the widespread adoption of the technology known as hydraulic fracturing (" fracking "). Concerns about toxic air emissions from previously unregulated fracking sites led to the U.S. Environmental Protection Agency announcement on 18 April 2012 ...

However, aviation biofuels are not just a lobbying gimmick. Oil and biotech companies, airlines and aircraft manufacturers, government agencies (particularly in the US) and venture capitalists are investing large sums into research and development of biofuels for aircraft. Recent test flights have shown that biofuel use in aviation is technically possible. Two types of aviation biofuels are in ...

Sediments sampled next to the Cíes Islands, a natural reserve of the National Park of Atlantic Islands in Ría de Vigo (Spain), 3 mo after the first tide of fuel from the ‘Prestige’ tanker arrived, were chemically and microbiologically characterized. The chemical analysis of the sediments, using oil fingerprinting techniques, showed the occurrence of fresh ‘Prestige’ fuel oil with a background o...

A combination of bagasse and waste oil, which is usually recovered in the industry from the effluent drains or at the machinery sections, is studied to generate a high CV fuel relative to the low CV bagasse fuel alone. The associated technical aspects such as excess steam generation, stack height requirements, economical returns due to the fuel mix are theoretically assessed in the present study.

Bio-jet fuel has attracted a lot of interest in recent years and has become a focus for aircraft and engine manufacturers, oil companies, governments and researchers. Given the global concern about environmental issues and the instability of oil market, bio-jet fuel has been identified as a promising way to reduce the greenhouse gas emissions from the aviation industry, while also promoting ene...
