Hydrogen vehicles: an irreversible process in the coming technological leadership

We were invited by the Japanese company based in Zarate, Toyota, to test new technologies that essentially come in the form of clean motorization in the face of the carbon emissions of current and traditional fossil combustion vehicles, which are the key to this 21st century. will end before the middle. Today we are going to present to our readers a report on the topic that has come to the editorial office of the multimedia EL DEBATE, written by the Integral Prevention of Spain.

The invasion of hydrogen as an energy factor cannot be stopped in the near future, because in theory, H is the most abundant and cleanest element and its utilization performance is due to its competitors (carbon and oxygen). is destined to be replaced. As their availability is increased in batteries and hydrogen generators.

In the struggle of the great public-private powers to introduce and dominate the energy sector with hydrogen, if they manage to avoid the abandonment of petroleum derivatives, no one doubts that this is an irreversible process and, It may hide from the individual user of vehicles and land, sea and air transportation systems, that it is useless to invest in any other source of energy other than hydrogen, which will accelerate the process of change. because hydrogen reserves and their distribution are priorities for the future objectives of mobility.

At this juncture, it is not surprising that motor experts such as Martí Figueres speak clearly in their writings that “Hydrogen-powered vehicles are said to occupy a preferential position in the new landscape that attracts the automotive industry of the future, although its high price and lack of recharging stations slow its progress and it goes a long way”, Reading Figueras’ article that we reproduce, leaves us no doubt about the fact that the advantages of hydrogen over conventional energy sources would so far accelerate its replacement.

“The automotive industry is making progress towards sustainable, emissions-free mobility. Paradigm shifts are already a reality, and in Europe, the European Commission-approved Green Deal is accelerating the process”.

The agreement establishes that all new vehicles registered in 2035 will have zero emissions. Broadly speaking, the decision adopted by MEPs includes the elimination of gasoline, diesel and gas vehicles (even if they have a hybrid engine) and their replacement by electric versions, more respectful to the environment. A vehicle equipped with one or more electric motors is not necessarily powered by electricity. Although it is the preconceived idea that many people associate an electric car with a conventional electrically charged battery, there is another power source for this type of vehicle: hydrogen.

A hydrogen car is a 100% sustainable electric vehicle, just like it plugs into a power outlet. The main difference is that it is powered by a fuel cell, a component that is installed at the front of the vehicle and is by far the most expensive part of the vehicle. When the hydrogen stored in the car’s tanks goes into the battery, it breaks down into protons and electrons. The flow of electrons created in the hydrogen fuel cell powers the electric motor, while protons react with oxygen molecules in the air, generating water vapor, the only emission that is expelled through the exhaust pipe.

Despite the benefits that hydrogen cars provide from an ecological point of view, it is a technology that is still rarely used. For now only two manufacturers, Toyota and Hyundai, both Asian, are making a firm and steadfast commitment to the hydrogen car. The Japanese brand has had a model on the asphalt since 2014, the Mirai, which is capable of traveling a thousand kilometers with just one hydrogen charge, while the South Koreans from Hyundai offer the Nexo with a range of 666 kilometers. Other companies such as the Stelantis Group, owners of brands such as Citron, Peugeot and Opel, are making an aggressive preparation to enter the world of hydrogen with a wide range of vehicles.

The high cost of the hydrogen car (the cheapest model costs about 65,000 euros) is one of the reasons that is holding back its expansion right now. But he is not alone. If only 7 copies were sold in Spain in 2020 that used this technology, it was not because of the large outlay that its acquisition represented, but, rather, because of the lack of recharging infrastructure. Currently there are only six stations in our country where hydrogen can be refueled (located in the provinces of Albacete, Ciudad Real, Huesca, Madrid, Seville and Zaragoza) and only the last three are for public use.

Today, Spain lags far behind other European countries, especially Germany and France, in setting up hydrogen plants. The hydrogen roadmap designed by the Spanish government predicts the construction of a network of more than 100 refueling stations distributed throughout the national territory by 2030. A measure that is going to happen with Naturaji Plants, which plans to install 40 hydro-generators before 2025. If the executive’s forecasts about infrastructure are met, it cannot be ruled out that by 2030 the Spanish fleet will have up to 7,500 light vehicles and hydrogen-powered heavy-duty buses and about 200 renewable hydrogen fuel cells. Buses.

fast charge

It is most likely that the impetus for this new technology will come from carriers, before hydrogen cars represent a particular firm option due to the lack of supply centers. Trucks and vans, as well as vehicles for transporting people, as well as buses, taxis and VTCs, will be in charge of pioneering this new alternative to ecological and sustainable mobility. With regard to electric vehicles, hydrogen ones offer more autonomy with a single charge and are faster to recharge. Refueling is done in just 5 minutes, a time that electric vehicles are still a long way from offering.

With regard to safety, although it is true that hydrogen is highly flammable under high pressure, it requires the presence of oxygen and an energy source that produces ignition. In addition, the use of high purity hydrogen in these cases significantly reduces the risk of fire. If a leak does occur, it also does not represent a serious danger, as it is a very volatile element and it dissipates easily without being concentrated in sufficient quantities at risk.
