The lying myth of the hydrogen economy

As I explained http://www.palmerini.net/blog/?p=65 hydrogen cars, although they remove smog from cities, I am an environmental nonsense, at most we are used to not change anything on the energy plan. Or even worsen the current situation.

Indeed, hydrogen is not one “Source” energy, as I am oil and its derivatives, but only a carrier of energy. Hydrogen works as a kind of "accumulator" , a battery, that is able to provide the same energy consumed to produce it, almost. But for the production of hydrogen you must use electricity, and / or heat, that they are produced using mainly oil and natural gas. The production process, is called “electrolysis”, and it has a cost, which is a further cost compared to the direct use of the fuel used to produce it.

Accounts in hand the hydrogen cannot be competitive as fuel compared to oil derivatives because, because it also derived from the oil consumption, it costs more by having an extra step of production. In fact, it is known in thermotechnics that each transformation of energy produces a loss of the same. for example, If you do oil gasoline, and gasoline do you fire, and with the fire you make steam, which shares a steam engine, at the end you will have less mechanical energy than it produces a gasoline engine, because you made an extra transformation of energy.

So this means that the hydrogen engine will be a convenient solution when the production of hydrogen directed by biomass will be made on an industrial level, for example from green algae, or from solar (panels that make electrolysis). Maybe then we would have some energetic advantage, of costs and environmental for the use of hydrogen with respect to the use of oil but this is still a solution to the experimental study.
However, not even then it will not be convenient to use hydrogen as an energy carrier in cars. Why ? Because hydrogen as a carrier is too expensive to manage and dangerous compared to the princely alternative solution that has been available since the 1930s.

E’ A very cheap and fully functional solution to accumulate energy without the risks connected to the use of hydrogen.

Compressed air !

I discover now that for years the compressed air has been used to store the surplus energy to consume it at the time of need.

In Germany, Under some electric production plants, enormous quantities of compressed air are stored in the depths of the earth.

This occurs when the consumption falls, and night, but the production continues in order to cushion the plants first or because the source is natural, as the water turbines.

With the energy not consumed, they "swell" of the immense underground reserves, as if they were huge cylinders. The day after, when the serving, If there is a peak of consumption, The compressed air is released to run air turbines, producing energy which integrate the production in progress and feed the electricity grid coping with peak consumption.

in conclusion, no need to store oil, Gas, methane, uranium or hydrogen.

A immense "energy" reserve can be created by transforming everything into the simple compressed air easily stored.

The compressed air has obvious advantages compared to other types of energy accumulators. If you break an accumulator (a cylinder), It explodes nothing as in the case of gas or hydrogen, Except of course the damage produced by the violent air leakage. It does not pollute like in the case of oil and batteries. The environment is not destroyed for centuries as in the case of the missing uranium and slag, as happened at Chernobyl.

The compressed air can be used for all uses. for example, With the use of solar panels you can recharge compressed air of small high pressure cylinders for home use, With the result that the panel can serve to give enough energy for home uses, day and night, accumulating energy slowly throughout the day when maybe there is no one in the house.

From these simple things it is clear that hydrogen is not a solution for the accumulation of energy.

Perhaps all this hydrogen advertisement has served to recover enormous research costs done for space flights and military technology. But in this case there is no advantage for civil uses. Much better than the simple compressed air.

In the meantime, which is cynfisch on hydrogen, The Tata Motors sends the compressed air car into production

Now the technological challenge is to be able to find a way to accumulate all the flutolences and bullshit in the form of compressed air that say certain politicians and certain comedians.
