Swiss company outlines methanol-to-gasoline option for Alaska North Slope gas to state legislature

Green Car Congress

Methanol-to-gasoline process flow diagram. The resulting methanol would be blended with crude and transported via the trans-Alaska oil pipeline to Valdez, where it would be extracted from the oil and processed via Methanol-to-Gasoline technology into gasoline. Gasoline could be delivered from Valdez at $2.65 Source: EMRE.

SwRI D-EGR gasoline demo vehicle delivers diesel efficiency at lower cost; potential for LEV III/Tier 3 emissions

Green Car Congress

D-EGR is a SwRI-developed gasoline engine concept that uses in-cylinder fuel reforming to produce CO and H 2 (with Research Octane Numbers of 106 and 130, respectively) and high levels of recirculated gas (EGR) to achieve very high levels of thermal efficiency. liter gasoline direct injection engine. The engine conversion.

New study finds GHG emissions from palm oil production significantly underestimated; palm oil biofuels could be more climate-damaging than oil sands fuels

Green Car Congress

Historical analysis shows strong acceleration of plantation development in recent years: 70% of all industrial plantations have been established since 2000 and only 4% of the current plantation area existed in 1990. That number is in my opinion conservative, and consistent with a slight reduction in the rate of peat conversion.

Study finds that replacement programs that reduce vehicle lifetime can result in increased lifecycle CO2 emissions

Green Car Congress

Effects of changes in the average lifespan of ordinary passenger cars newly registered between 1990-2000 on total induced CO 2 emissions in 2000. Conversely, encouraging shortened vehicle lifetime via vehicle replacement schemes can result in higher total-induced greenhouse gas emissions, the authors found. Click to enlarge.

EIA: China’s use of methanol in liquid fuels has grown rapidly since 2000; >500K bpd in 2016

Green Car Congress

Annual methanol consumption in China, 2000-16. EIA research indicated that part of the reason for the underestimation of transportation sector consumption of liquid fuels stemmed from the use of methanol and its derivatives that were increasingly added into China’s gasoline and liquefied petroleum gas (LPG) streams.

SwRI develops D-EGR demonstrator highlighting fuel-efficient, cost-effective engine; 10% and above fuel economy improvements

Green Car Congress

Southwest Research Institute (SwRI) has built a demonstrator vehicle, based on a 2012 Buick Regal GS, incorporating the latest D-EGR (dedicated EGR) technology ( earlier post ), an outgrowth of SwRI’s HEDGE (High Efficiency Dilute Gasoline Engine) consortium projects ( earlier post ). In 2013, SwRI reported a 2.0-liter
