MIT team proposes flex-fuel gasoline-alcohol engine PHEV long-haul trucks

Green Car Congress

In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. Ethanol or methanol would be employed to increase knock resistance. —Daniel Cohn.

MIT researchers advancing development of supercritical water upgrading of heavy crude; lower cost, energy use and CO2

Green Car Congress

Findings by MIT researchers could help advance the commercialization of supercritical water technology for the desulfurization and upgrading of high-sulfur crude oil into high-value, cleaner fuels such as gasoline without using hydrogen—a major change in refining technology that would reduce costs, energy use, and CO 2 emissions.

ExxonMobil, MIT and Synthetic Genomics team publishes results of LCA on algal biofuels; potential for large reductions in GHG

Green Car Congress

Algae have the potential to produce large volumes of fuel per unit area of production on marginal lands using saline water unsuitable for food crops. Thus, algal biofuels could expand transportation energy supplies, without significantly displacing land and water resources that would otherwise have been used for food production.

Water will be the primary byproduct. This process will repurpose carbon dioxide for use as a liquid fuel that can be readily used as a high octane gasoline substitute. The team anticipates at least a twofold productivity improvement over current levels and a cost that can be competitive with gasoline. per gallon. Harvard, Univ.

These fermentation processes create carbon as a byproduct, with some processes wasting more than 1/3 of this carbon as CO 2 emissions. At commercial scale, the inputs to the proposed “carbon refinery” process are carbon-free renewable energy, water, and CO 2. Ohio State University.
