Taking another look at methanol as an alternative transportation fuel for the US

Green Car Congress

Large scale production of methanol from natural gas and coal is a well-developed. Sufficient feedstock of natural gas and coal exists to enable the use of non-renewable methanol as a transition fuel to renewable methanol from biomass, they suggested. The toxicity (mortality) is comparable to or better than gasoline.

IEA: carbon intensity of global energy supply has barely changed in last 20 years; “window of opportunity in transport”

Green Car Congress

In a fairly bleak assessment of global progress towards low-carbon energy, the International Energy Agency (IEA) concluded that, despite a few bright spots such as the rapid expansion of renewable technologies and the growth of hybrid and EV sales, the progress is far below that required to achieve a 2 °C pathway—i.e.,

Use of Supercritical Diesel Fuel for Improved Efficiency and Reduced Emissions

Green Car Congress

Heat required to bring the fuel to SC states is recovered from the exhaust gas of the engine. Given the high reactivity of diesel fuels compared to gasoline, the ignition and combustion of pre-mixed fuel-air charges poses a challenging control problem. Earlier post.). At SC conditions, however (T?450 450 °C, P ?600
