GGR370H5 Lecture Notes - Lecture 4: Hydrogen Fuel, Cardiovascular Disease, Tetraethyllead
Document Summary
Energy content of a resource = available energy per unitof weighti volume. Higher the energy content of a fuel , the higher the fuel quality. Low quality fuel = solid e -g - gasoline and coal are regularly used, gasoline is much higherquality fuel than coal. " chemical makeup of fuel can be used for different tasks e -g . Kerosene ci-e . forjetplanes) is used because of its exposure to high attitudes and low temperatures. " maritime shipping , bunker sea fuel is consider the lowest quality fuels in liquid form , but its suitable for engine uses in large containerships. " although methane and hydrogen are more efficient than others , these form of energy come with disadvantages of the difficulty for storing (cid:8869) must be synthesized which also requires energy. Requires 100 hours to capture the solar energy equivalent of 1kg of gasoline using solar panels covering 1km"
