NOT YET, BUT STRONG GROWTH – there is good reason to believe that in a few years, we’ll all with anelectric car: for the majority of users is not yet the most convenient solution and, for those who do not have the opportunity to carry out easily the refills, it is not even feasible. But it is also true that the progress has been enormous, that supply and demand are in strong growth, and that there are other solutions (hybrid cars, rechargeable, cable, or less) that utilize batteries and motors to reduce emissions of CO2 and pollutants to the exhaust.
In the photo above, the concept Hyundai 45.
IN FIVE YEARS, MULTIPLY by TEN , All the houses are working a lot in electrification and the Korean Hyundai is one of the most active. His range of vehicles is very diverse, also with regard to the engines. Suffice it to say that the compact crossover Kona is proposed in the versions with gasoline, diesel, hybrid, rechargeable and electric, and that there is a model that is comparable (the Nexo, not imported in Italy) electric, but the hydrogen-powered: no batteries, but fuel cells (fuel cell) that transform in the current. A recent meeting with the leaders of the Korean house, we later clarified what are the goals for the future. You are very ambitious: by 2025, the idea is to invest 35 billion euros to spend from about 60,000 electric cars sold in 2019 to 560,000 units, with an offer that reaches 23 models; in addition, it is planned to put into circulation each year of 1.11 million Hyundai hybrid (taking into account that today there are around 300.000). On the basis of these numbers, there will also be the introduction, next year, a model based on the prototype presented at the last Frankfurt motor show, the Hyundai is 45 ev. It will be the first car to use the modular platform for electric cars EGMP (Electric Global Modular Platform), which will be shared between the models small, medium and large. But it will not be the only technical base for the car battery will continue to exist, the cars (as it is today the Kona, for example) that will offer different types of propulsion.
In the diagram above, the power supply system of a truck to hydrogen.
ELECTRICAL TRUCK? YES, BUT HYDROGEN – The Hyundai is at the forefront of vehicles to hydrogen, up to now very little popular mainly because of the lack of centers of supply (the gas must be stored at high pressure up to 700 bar) and for the high cost of the fuel cell. In Italy, thanks to the creation of a point of production and supply, are in use in Bolzano (from local businesses, Police and Carabinieri) a dozen suv ix35, to which was added a few months ago, a Nexo, used by Autostrade del Brennero. But where this technology seems to have the best short-term prospects in heavy vehicles to the electric motor. Build a truck battery with a good battery and would, in fact, the presence of such a quantity of accumulators to grow much the price and reduce in a manner unacceptable to the load capacity. To increase the autonomy with the hydrogen on the contrary, means only the increase of the number of cylinders where to store the gas, which impacts minimally on the weight, dimensions and costs. In short, an electric truck you can do; but with the batteries it makes no sense, while with fuel cells, hydrogen-powered yes. And it is on a project of this second type, which has worked with Hyundai, in Switzerland: you will start in 2020 with 20 vehicles, to get to 1600 in 2025; these trucks have 7 bottles filled to 350 bar, stacked between the cabin and the trunk, while the fuel cell and the electric motor (little bulky), respectively, are under the cabin and under the floor. Hydrogen will occupy the Alpiq, a supplier of electricity based on electrolysis, in turn, obtained through hydroelectric power plants (the power requirement will be 2 MW next year, up to 100 MW in 2025). In Switzerland, a country rich in mountains, the water comes about 60% of the electrical energy.
A charging station for electric cars of Ionity.
IT ADDS TO IONITY – The creation of these points of supply would pave the way for the use of other hydrogen vehicles. In this sector, Hyundai plans to invest us $ 6.7 billion by 2030, with the target for that year, to produce over 700,000 units. Of these, only 500,000 should be for cars and heavy trucks, while 200,000 may relate to the marine (large ships), industrial and so on. It is understood that the company is dynamic and remains open to multiple solutions in an industry that is rapidly changing. To stay up to date with the progress of the situation in Europe, Hyundai (and Kia, which are in the same group) are about to become part of Ionity, the joint venture founded in November of 2017, which so far has had as its members BMW, Daimler, Ford, Volkswagen, Audi and Porsche, and the purpose of which is to build charging points for public, high-power (up to 350 kW), places along the highway: what it takes to make electric cars usable even on long trips. The goal, in this case, is to install 400 stations (with six columns each) distant from each other 120-150 km; 165 are already operational, mainly in Northern Europe, and the other 65 that are coming, including Italy; Ionity, in fact, has reached an agreement with Eni to install these units super fast in its service stations. Are not all sunshine and roses, however: the speed of charging depends not only on the power of the column, but also by the capacity of the drive, to accept a provision so generous of the current; otherwise, the stop time grows a lot. In addition, even in the laudable goal of clarity, Ionity has decided that each refill you pay 8 euros (or 8 francs in Switzerland); so, unlike what happens with other suppliers, there is no surprise, but it is also true that, if we only stop for a “topping”, because you do not have time to wait, the expense for each kWh can become challenging.
