If you consider within the tooth fairy, or vote Inexperienced, you in all probability consider that hydrogen is the magic rainbow gasoline that can banish international warming, exchange depraved hydro-carbons in electrical energy technology, gas tomorrow’s vehicles, planes and heavy tools, and earn limitless export earnings.
There may be one large downside – not like coal, oil and gasoline, there are not any hidden swimming pools of hydrogen we are able to faucet. Each little bit of hydrogen must be manufactured from water or hydrocarbons utilizing big quantities of power.
The power content material of liquid hydrogen is about 70% of the power required to provide it. Burn it in a mixed cycle gasoline turbine (power effectivity 50%) and see that power return drop to round 35%. Use it as car gas and see power effectivity fall even additional.
The density of liquefied hydrogen is far decrease than that of pure gasoline – thus the transportation prices will probably be larger. And since the tiny hydrogen atom finds any small leak, the protection dangers are very excessive – think about a highway accident involving flammable lithium batteries plus explosive hydrogen gasoline.
Most hydrogen is made immediately from coal, oil or pure gasoline and the principle course of produces hydrogen and . . . extra of the dreaded CO2.
However hydrogen is cherished by Huge Greens and little kids as a result of it has been named in a rainbow of fairly colors: gray, brown, black, inexperienced and blue.
Gray hydrogen comes from pure gasoline, brown from lignite (brown coal), and black hydrogen is constituted of black coal (no surprises there).
Inexperienced hydrogen is produced by electrolysis of water utilizing intermittent inexperienced power like photo voltaic or wind energy. It requires heaps of recent water and electrical energy neither of which might ever be absolutely recovered. Each tonne of hydrogen makes use of 9 tonnes of water.
Blue hydrogen is any of the above however the CO2 by-product is saved in carbon cemeteries, making blue hydrogen stupidly costly.
