Data la sua estrema volatilità, è p

Data la sua estrema volatilità, è praticamente inesistente allo stato puro sulla Terra. Infatti lo si può trovare sotto forma di composti e la sua fonte più comune è appunto l’acqua, a sua volta presente in ogni materia organica. Non può essere considerato dunque una fonte primaria di energia come lo sono attualmente il gas naturale, il petrolio ed il carbone, che possono essere ricavati direttamente dai loro giacimenti, a prescindere da processi di raffinazione o meno. Per questo, per poterlo utilizzare, l’idrogeno deve essere ricavato dagli stessi materiali in cui è presente tramite processi industriali. Per quanto riguarda il suo impiego sono stati fatti importanti investimenti, in quanto l’idrogeno potrebbe non solo sostituire i tradizionali combustibili nei motori a scoppio, ma può anche essere utilizzato come fonte di elettricità nell’emergente tecnologia delle fuel cell, ove esso non viene combusto, ma si comporta da ossidante. In tale ambito si otterrebbe un’efficienza nettamente superiore, dovuto essenzialmente ai minori sprechi e perdite che si denotano nelle tecnologie attuali. Sono numerosi i vantaggi che si potrebbero riscontrare nel caso dell’utilizzo dell’idrogeno come combustibile. Innanzitutto può bruciare in un intervallo di concentrazione nell’aria che varia dal 4% al 75%, quando il gas naturale invece ignisce in un intervallo molto più stretto, compreso fra il 5,4% e il 15%. Il diidrogeno presenta inoltre una temperatura di auto-combustione superiore (585°C) garantendo quindi maggiore sicurezza e stabilità nel suo impiego. L’unico svantaggio deriverebbe dalla sua densità di energia, che è significativamente inferiore rispetto ai tradizionali combustibili e quindi necessita di essere compresso a pressioni più elevate nella fase di stoccaggio.

given its extreme volatility, it is virtually non-existent in the pure state on earth. in fact it can be found in the form of compounds and its most common source is precisely the water, in turn present in each organic matter. therefore can not be considered a primary source of energy as they are now natural gas, oil and coal,that can be derived directly from their reservoirs, regardless of refining processes or less. For this reason, in order to use, hydrogen must be derived from the same materials in which it is located through industrial processes. as regards its use are important investments were made,as the hydrogen could not only replace conventional fuels in combustion engines, but can also be used as a source of electricity in the emerging technology of fuel cell, where it is not combusted, but behaves as an oxidant. In this regard we would get efficiency gains,mainly due to reduced wastage and losses that denote the current technologies. there are numerous benefits that you may encounter in the case of the use of hydrogen as a fuel. firstly can burn in a range of air concentration that varies from 4% to 75%, when the natural gas instead ignisce in a much narrower range, between 5,4% and 15%. the dihydrogen also has a top temperature of self-ignition (585 ° C) thus ensuring greater security and stability in their employment. the only disadvantage derives from its energy density, which is significantly lower than conventional fuels and therefore needs to be compressed to higher pressures in the storage phase.

Given its extreme volatility, is virtually non-existent in its pure State on Earth. In fact, you can find it in the form of compounds and its most common source is water, which is present in any organic matter. Cannot be considered a primary source of energy as they are currently, natural gas, oil and coal, that can be obtained directly from their deposits, regardless of whether refining processes. For this reason, in order to use it, hydrogen must be produced from the same materials where it is present through industrial processes. As for its use were made important investments, because the hydrogen could replace traditional fuels in internal combustion engines, but can also be used as a source of electricity in the emerging fuel cell technology, where it is not burnt, but acts as an oxidizing agent. In this area you'd get much higher efficiencies, due primarily to lower waste and losses that they denote in today's technology. There are many advantages that you might experience in the case of the use of hydrogen as fuel. Firstly can burn in a concentration range in ambient air that ranges from 4% to 75%, when natural gas instead ignisce in a very narrow range, between 5,4% and 15%. The Dihydrogen also features a self-combustion temperature (585° C) assuring greater safety and stability then in use. The only drawback is derived from its energy density, which is significantly less than traditional fuels and therefore needs to be compressed to a higher pressure in the storage phase.

In fact he may be found in the form of compounds and its most common sources and precisely the water, in turn present in any organic substance. It cannot be considered a primary source of energy as they currently are natural gas, oil and coal,That may be obtained directly from their deposits, apart from refining processes or less. For this, to make use of it, the hydrogen must be obtained from the same materials in which is present through industrial processes. As regards its use has been made important investments,Because hydrogen could not only replace the traditional fuels in internal combustion engines, but can also be used as a source of electricity in the emerging technology of the fuel cell, where it is not burned, but it behaves from oxidizing. In this context would be an efficiency much greaterMainly due to less waste and losses which you suffer in today's technology. There are several benefits that may be encountered in the case of the use of hydrogen as a fuel. Initially it may burn in a range of concentration in the air that varies from 4% to 75 %, when the natural gas instead ignisce in a range much narrower, between the 5,4% AND 15 %. The dihydrogen also has a temperature of auto-combustion higher (585 °C) thus ensuring greater security and stability in its use. The only disadvantage would result from its energy density, which is significantly lower than traditional fuels and therefore need to be compressed at higher pressures in the storage phase.
