There are now many applications of everyday life that use electricity from hydrogen fuel cells, such as the washing machine and dryer made of Electrolux recently from Italy, fuel cells and renewable prove that the winning couple to address the environmental challenges of the twenty-first century, while the energy bill turns out to be an indirect way to promote hydrogen technologies.
The development of fuel cell technologies, the so-called "fuel cell", in particular hydrogen and methanol, has had rapid growth in recent years. Applications are now able to put into effect what had been spent so far in terms of words of hope and potential markets. Many applications demonstrate the feasibility: in private homes, in robotics and facilities for film, up to large multinational appliance, surveillance, lighting, road signs. A insieme di applicazioni trasversale a ogni attività umana, che può garantire vantaggi pratici, economici e ambientali molto grandi in futuro come nell’immediato.
La rapidissima corsa delle installazioni fotovoltaiche o eoliche nel nostro paese e piu’ in generale in Europa sta rendendo interessante l’idrogeno come strumento per accumulare i surplus energetici. Gli incentivi statali, come il Conto Energia per il fotovoltaico, sono il punto essenziale dal quale non poter prescindere. Per risolvere i problemi contingenti di alcuni specifici areas where you need to limited power, within the 500-1000 W, you can use fuel cells with a solution of distilled water and 10-15% methanol, which can remedy the problems of hydrogen storage. Here are a few examples, we refer to the autonomous road signs, monitoring of weather stations, volcanic and seismic surveying, telecommunications, security and surveillance. In other words: more 'than to prototypes, today's hydrogen and fuel cell peak integration in daily life.
- PRODUCTION FROM RENEWABLE - The facts show that the hydrogen is ready to play the role of energy carrier for distribution via capillary also hydrogen pipeline networks in small city / county to be used in many applications. This is a great "energy carrier" because it has a calorific value that it be given equal weight, two times more 'energy of the gas and up to three times more' more 'energy' common petrol. It can produce hydrogen from a variety of sources (fossil and renewable) and energy carriers (electricity), but the most 'interesting is that with electrolysis process, which can now be characterized by excellent efficiencies (70-80%), not only produces high purity hydrogen for industrial and marketability, as well as pure oxygen and attractive to industrial and commercial. We refer often to renewable energy as a potential source for hydrogen production by electrolysis to hydrogen as the primary process, because represents one of the few methods of hydrogen production, free from any type of issue. Electrolysis is very energy efficient in some cases but difficult to implement on a large scale, or replicated on a larger scale 'but in a great imitation as a result of economic factors and efficiency, as in the case of photovoltaics. If we focus just on photovoltaics, we can easily realize how the Energy Bill is unintentionally an extraordinary incentive for hydrogen technologies : every investment KW PV in more than your needs is really a valuable investment in order to obtain two highly profitable gas (hydrogen and oxygen), with effect from production cuts of 60 l / h. In short, waiting for the networks and infrastructure of hydrogen are produced, small producers of renewable energy from solar and wind power have the potential producers of high quality hydrogen through the most 'clean and simple process : electrolysis. This is due to the incentives and mechanisms for metering and transfer network, which can make much more 'approachable electrolysis over other methods of production, especially in the case of small flows. This vision fits perfectly with what is a logical infrastructure more 'long-term means the introduction of hydrogen into hydrogen pipeline to typical lengths of 100-150 km that will ensure economic returns comparable to those of today's networks of methane. At the same time, the logic of the on-site hydrogen production from solar solves the first problem, that is, once and for all break the vicious circle linked to the eternal chicken and egg problem: they must be built before the infrastructure for gas distribution and then the applications or the opposite?
- STORAGE SYSTEMS - The main advantages of the technology-fuel Hydrogen than conventional secondary batteries are multiple dimensions and lower weight, longer life, virtually no maintenance. But today, most point is' that the competition with the traditional methods of energy storage batteries for integration with these last for a full exploitation of the peculiarities and advantages of both technologies. So there is always the most 'frequently in partnerships between the new technological frontiers of the methanol fuel cell and hydrogen with the world of batteries, in order to optimize the life of both devices in order to achieve the ideal economic and satisfaction requirements and objectives of technical installations. So then the fuel-cell generators are transformed into autonomous electricity , working with alternative fuels with zero emissions, but which may become necessary ideal partner for the batteries if the need arises and to minimize their charging cycles and hours of operation of the fuel cells themselves. The real battery charger and zero emissions, which solve many problems in key areas of daily life, from the UPS, until forced to isolated dwellings, as a rule, to rely on generators to numerous pollutants and fossil fuels.
