These new compounds were not previously known to exist, and raise additional concerns about the health impacts of heavily-polluted urban air or dietary exposure. PAHs form naturally as the result of almost any type of combustion, from a wood stove to an automobile engine, cigarette or a coal-fired power plant. Staci Simonich.
A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.
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. Methanol from non-renewable coal or natural gas could be used as a bridging.
