But that hydrogen cars !
Over time, several petitions have circulated to have the hydrogen distributed to replace the oil. And for many years comic (and not) They told us that the hydrogen car was the solution of the future. Even many car manufacturers such as BMW have a hydrogen car in the catalog. Every now and then someone refers alive with this track, which I then explain why it wishes from the problems.
Years ago the Lombardy Region, To make a hydrogen distributor and promote this technology, Expenses a lot of public money, that after the print demonstration in fact only a few days were used. Jeremy Rifkin has also been shaking for years for the hydrogen issue.
In short, there is no doubt that many have thought they can finally reduce pollution and environmental impact, and they tried to convince us that hydrogen is “the” solution, Rather, the only one worthy of being listened to. At least until they went on to promote the self -electricity based on lithium batteries that are demonstrating bankruptcy.
Yet in both cases, it was enough to get informed and understand that the hydrogen proposed as a replacement fuel of petrol or diesel is a non -solution that aggravates the ecological problem, And here's why.
Meanwhile, we say that hydrogen is used in a large number of chemical operations, but it is mainly obtained from coal and oil through the “decomposition” water in hydrogen and oxygen called electrolysis.
(adding 28/11/2007) The process of transforming water (H2O) oxygen (“The”) and hydrogen (i due “H” ), It is called electrolysis and is accomplished with the simple electricity and the use of special metal plates. L’ electricity can come from any source, including solar panels, or wind generators, or Nuclear, But in this case, electure is used and consumed to split water in hydrogen and oxygen. For oxygen there is no problem using it or free it, while hydrogen can be accumulated and reused in the various industrial ways.
However, it is not enough to put hydrogen in cylinders and adapt cars to use it as you do with methane gas or LPG, The hydrogen car has a completely different system of transformation of the motion, In essence, current cars cannot be converted to work at 100% hydrogen.
However in essence the point is that hydrogen does not come “extract” from the earth or the environment, Instead derives from the consumption of other energy. Therefore hydrogen, The finished product, We can accumulate it in cylinders, and reuse it as if it were a battery, But it's not one “Source” energy, but a simple “vector” energy. In this sense, hydrogen is probably less polluting than batteries, maybe it would be useful to accumulate the energy of dams, wind turbines and solar panels, But with this it does not mean that the hydrogen car is a good idea or a solution to the energy problem.
In fact the problem is : where we take that energy that then “we store” in hydrogen?
To produce hydrogen, oil are used today, methane and coal. This at least until before the war in Ukraine of 2022 So today the Western authorities disincentive Russian methane and speculation makes him pay very dear probably to finance the war.
Comque, the fact is that each “transformation” dell’ energy makes it lose some. You lose energy to do the’ electricity from oil (or methane), and energy is lost when electricity is used in electrolisi to produce hydrogen .
So certainly more oil and fossil fuels are consumed to accumulate hydrogen instead of using them directly in the combustion and in the generation of energy on site.
Put another way, As long as we use fossil fuels to produce hydrogen, The final balance of the use of hydrogen for automotive would therefore be a greater consumption of them, because energy is lost in the transformation. Without considering that the plates used for electrolysis are not cheap, So at the moment no economic method is known and verified that allows economic electrolysis. If someone has the opposite, write me too.
About fifteen years ago it was believed that the peak of oil had come, that is, that resources would begin to scarce, while the arrival of China created a continuous greater consumption. Fortunately, many other deposits have been discovered and technologies refined, But the problem of combustion pollution has not been solved.
sure, we could also use the solar panels to produce electricity and use it to accumulate hydrogen. Or of nuclear power plants, But recently also France had to start paying Uranus 200 Euro/kilogram instead of less than one euro, And this shows that nuclear power (including slag management costs) It is not a solution even that.
We can use solar panels or other to produce hydrogen from water, But the poor production of hydrogen that we can thus obtain is not enough to feed a car. And in any case, Why consume that hydrogen in new motor vehicles, rather than simply use it to heat the house? In this way the hydrogen would serve for what it actually is, a type of “accumulator” energy. Instead, currently those who have the solar panels from the current produced to the network manager, and in return it receives a discount (perhaps) but still pays more than it receives when the current buys it . Perhaps even in this case the hydrogen may not serve, A more suitable and safe solution for the accumulation of energy could be the compressed air that is used at every tire dealer.
The sums are currently useless to think of investing in an hydrogen car system because today we would not have hydrogen produced without polluting and inevitably we would end up using oil to make the necessary hydrogen going to aggravate the problem of pollution that we wanted to solve.
Perhaps it will soon be able to produce sufficient hydrogen from the organic masses of green algae (see this page) or other organisms.
At the moment ( the next 30/50 years!), talk about hydrogen cars as a solution, It only means paying attention to the problem of the origin of energy, and polluting the world with scrapped cars instead of simply heating the buildings and thus starting to truly reduce the consumption of fossil fuels.
On the other hand, the much cheaper and safe cars are already made Compressed air which could be improved to solve the problem of freezing from depressurization.
Practically, The famous hydrogen car does not pollute in the city, but it pollutes where hydrogen is produced because oil is used. And indeed consumes more oil and energy to be able to use hydrogen as a carrier.
For more, To produce hydrogen you must make large plants. There has been talk several times to make the largest hydrogen production center in Marghera, near Venezia. In practice, all the car pollution of Italy would be released in the atmosphere a 5 kilometers from Venice, destroying the monuments . On the other hand, the area between Marghera and Padova is already the area with the highest rate of tumors and cancer in Europe.
Apart from the non -sense of making enormous investments so as not to change anything in terms of global pollution, the hydrogen cars require a new fuel distribution system, then new stations, new cars, new plants …. especially the complete replacement of the entire machine park. But we have an idea of how much this useless change of technology will pollute ? The bulk of the pollution does not produce it when it is used, but when it is disposed of.
The problem of the humble expenditure of energy to produce hydrogen seems to also affect the so -called synthetic fuels, which, however, could encourage a softer transition.
And yet it should be highlighted that it is the use of biofuels that the use of methane are ready -made solutions, ecological and economic. Unfortunately, the regimes disincentive their use also by bringing out the diesel engines.
When I saw Grillo to breathe the escapement of a hydrogen car I wondered what study he had done to start offering him. Or maybe these start recycling without understanding ?
By a comparison on the field of 2020. a magazine concluded that The hydrogen car is certainly not cheaper than the methane one, but not even of the electricity. The alternative to diesel petrol are biocarbulants, which have existed for decades, And if there is an alternative to the internal combustion engine I believe it is L’ compressed air car. I did a separate post.
Since hydrogen is a false myth because to do the’ hydrogen is needed oil, And the same can be said for the self -electric that is not mature until the batteries are used like those in salt, From these elements it is clear that the occult government of the world does not want to take off the new era without oil, And it brakes humanity, at the cost of keeping it in the war for control of resources and technology, or making war on those who have resources but do not undergo their will.
That they are also available to a nuclear war rather than leave us free ?
Moreover, The technology associated with oil will probably never be replaced, Because there is a natural petroleum substitute produced in the middle of the desert with green algae, vedi http://www.palmerini.net/blog/?p=188 (Added March 2008)

But the compressed air from where it is obtained in your opinion?
Obviously the energy necessary to compress the air is obtained from fossil fuels!
Whether hydrogen or compressed air is used to produce energy. E’ now that then begin to produce clean energy! This is the point!!

Some time ago, There was a guy who affirmed the earth was round! Think unconscious!
Seriously, my irony, It underlines the fact that it is the culture and interests that make a difference even when it comes to clean energy. Let's leave aside our individual and insignificant lives and begin to think more broadly! The needs of all, They are more important than the needs of a, But the single unit is part at the same time of the whole, then our destinies are inextricably tied to each other to the vicissitudes.

Hello everybody.
In my opinion we should not rely heavily on transport by car but very Transport by train though with the necessary changes. Have you ever heard of the Maglev Train? This train uses the technology of magnetic repulsion and magnetic attraction; In truth it was already experienced many times and a very reliable train turned out, fast and low-power(If not the consumption of electricity). It was already installed in Japan to connect 2 States of land very distant from each other and in other parts of the world and we are also talking in Switzerland to create underground connections in the absence of air to make the speed of the speed to the train to say the least drugs(we talk about 8000km / h) and in the presence of friction(air) It has already proven that the train can reach a speed between 400 Hey 500 km/h. In my opinion this is an innovative technology, Since the solution to pollution are transport then we invest in these types of transport and not in methane or hydrogen or compressed air. These are the ideal transport for a better future and less polluted. A network of transport of this kind in Italy would lead to a considerable expense but we(as a nation) We spend a lot more money to get oil and so on, So why not invest the money in these emerging technologies?? At this point a gambling account, if this technology has been used for trains… why we not also use for urban transport? E’ a gamble but it could also be implemented on motorways and car. Think about it and tell me what you think!

David Caro, although it may seem strange, Hydrogen is more’ secure than today's fuels in use. If a motor vehicle powered by hydrogen ignites; compared to its counterpart powered petrol, diesel fuel, a gpl, It undergoes less damage. On the internet there are several sites that have simulations (video clips) about it. Here is enough for me to remind you that the combustion speed of hydrogen is far superior to the fuels of which before (in practice a kg of hydrogen burning in a shorter time compared to the fuel above, for which it produces minor damage) and that his bird is far superior (Have you ever wondered why it is forbidden pargheggiare a car on gas in an underground garage?). With sympathy. franco

dear Mr. palmerini,
She probably is confusing, or worse, He wants to confuse those who read. From what you write, It is deduced that hydrogen is obtained exclusively from oil, and this statement is false, as the, if it is true that the industrial production of hydrogen is, to date, economically more’ convenient if this is derived from methane (CH4); It is equally true that this is not the only way to produce it. He has ever heard of water electrolysis? And before I come to say that the production of electricity, or that the use of water (precious good) etc. I take advantage of removing that electricity is also produced with photovoltaic solar panels, and process water, It is obtained from sea water by means of solar deselators, that have a fraction of the cost

I would also like to add the dangerousness of a hydrogen machine in the eventuality, a road accident occurs. Not to mention the minimum displacement: the BMW prototype was equipped with 6000 cc, an acceptable capacity to travel with this technology.
