“…Because of the high octane index, high heat of vaporization and low combustion temperatures, the power and efficiency is significantly higher for methanol (and ethanol) compared to gasoline. This is certainly true for highly pressure-charged engines, where aggressive downsizing is possible on these alcohols [14].…”

-Removing the biomass limit is one of the great challenges to further enlarge the share of renewable ethanol as alternative for fossil fuels. One of the possible solutions for this constraint are the ternary GEM (Gasoline-Ethanol-Methanol) blends. The air-to-fuel ratio of these blends is hereby chosen at the value of an E85-blend (9.75 kg air/ kg fuel) while the ethanol is replaced by methanol/gasoline and therefore these blends are called 'isostoichiometric'. If the methanol is produced out of renewable sources, these blends can help extend the part of clean fuels on the market. The ternary blends show few differences in physical properties for the total range of possible blends and are considered as drop-in alternatives to the original E85-blend for a flex fuel engine. In this paper the performance and engine-out emissions of four of these GEM-blends were examined on a 4 cylinder 1.8 l PFI production engine. A single cylinder engine with high compression ratio was used for a preliminary study of the knock behavior of these blends. The measurement results are compared with those on neat gasoline, methanol and ethanol to demonstrate the potential of these ternary blends as a fossil fuel alternative. All the GEM fuels which were tested gave very similar results to E85 and can therefore indeed be used as 'drop-in' fuels for flex-fuel vehicles.

“…Any alcohol blend with low gasoline content would operate in such an engine. Work at the EPA laboratories in Detroit (Brusstar et al, 2002) and at MIT (Bromberg & Cohn, 2008) has shown that both M85 and E85 in a low-displacement, spark-ignited, high-compression gasoline engine can obtain efficiencies exceeding that of diesel engines. So, in effect not only does this eliminate the near-factor-of-2 calorific (mileage) penalty of methanol, but you end up with a smaller engine that gets better mileage than a gasoline equivalent.…”

Shale Oil and Gas: The Promise and the Peril, Revised and Updated Second Edition

In the first edition, Shale Gas: The Promise and the Peril, Vikram Rao explained that shale gas has the potential to transform the U.S. energy-based economy in the electricity, transportation, and chemical sectors. Since then, shale oil burst into the national consciousness even more rapidly than did shale gas. In the second edition, Rao does more justice to the shale oil–related issues, including the consequences of unpreparedness of infrastructure to deliver fluids to market. Six new chapters discuss issues such as chemicals disclosure and challenges to the orthodoxy in the production of fuels and chemicals. Both the first and second editions are intended to inform both sides of the fracturing debate, where currently rhetoric is overtaking understanding. Tailored for a nontechnical audience—with technical chemistry and geology information couched in sidebars—the second edition culminates in suggestions for research and guidance for policy making.

Shale gas has the potential to transform the U.S. energy-based economy in the electricity, transportation, and chemical sectors. U.S. success can be expected to translate to Europe and other parts of the world. Shale gas production is uniquely enabled by hydraulic fracturing, a technique that has come under heavy scrutiny for its potential to cause environmental damage. In this book, Vikram Rao addresses the issues surrounding shale gas in a balanced fashion. The book is intended to inform both sides of the fracturing debate, where currently rhetoric is overtaking understanding. Tailored for a nontechnical audience—with technical chemistry and geology information couched in sidebars—the book culminates in suggestions for research and guidance for policymaking.
