VDE study: The battery electric drive is the future

For passenger vehicles, the battery electric drive is the art alternative to the internal combustion engine. Of this, 27 opinion performers from politics and economics ied the electrical engineering and it association vde for his study published on friday to the drive portfolio of the future. As a reason, they call the already quite widespread distribution of electric cars, the good energy efficiency as well as the existing flat-covered electricity grid infrastructure.

The large challenge shows the experts in this area still in the construction and expansion of a demand-based charging infrastructure. Here you can expect capacitentsengzas at an increasing number of e vehicles. Dafur had to be created in the form of network expansion and intelligent load management.

"On the electric car no way passes"

To the politicians who participated in the survey, karl holmeier (csu), arno clear and falko mohrs from the spd, the liberal mario brandenburg and daniela kluckert, cem ozdemir and anna christmann from the grunen and johannes wieczorek from the federal ministry of transport. From the economy were managers and technicians of audi, bosch, hyundai, iveco, linde, electricity network hamburg and varta. There were representatives of research institutes such as the diw and business consultant.

The respondents are "pretty agent" been that on the way to the destination "zero emission" and the climate neutatility of the transport sector on the battery-powered electric car no way pass, ralf petri, divisional manager of the business area mobilitat in the vde, explained in the presentation of the results. Everyone had the "central statement" supports: "we have to use renewable energies as efficiently as possible as possible. For the car area, this: possible battery-electric."

Hydrogen and fuel cell

For trucks from 12 tons and overland buses, the experts slowly bring hydrogen and the fuel cell into the conversation according to the analysis. You can see a big chance here in heavyweight learners up to 40 tons as well as in the areas of rail, ship and aviation, where mailly weight and reach play a rough role.

Heavy duty traffic causes around one third of the co2 emissions of the entire transport sector today. For this reason, the fuel cell applies to the opinion performers as an important building block on the way to local, co2 neutral mobilitat in these application traps. Prerequisite should be that "gruner" hydrogen is used, which was obtained from renewable energies. But also here are the challenges in infrastructure expansion as well as importing imports for green hydrogen.

So far, there are only a little more than 90 hydrogen tank stations in germany, petri was a view of the actual state. With the fuel cell vehicles with the hyundai nexo, the toyota mirai and the mercedes glc f-cell are only three offers in the german market, during the battery cars everything from the small car to the luxury segment with porsche and tesla be covered. "Engraving technology", which allows for a cost reduction as in the battery cell, are not expected.

Niche market e-fuels

For e-fuels, ie synthetic fuels that are produced by means of electricity from water and carbon dioxide, especially speaks the simple distribution. For this, the existing infrastructure of pipelines, transport trolleys, petrol stations, petroleums can be used. The incoming internal combustion engines also remain in the race.

However, the production of these fuels on average requires the six to eight-fold amount of primary energy compared to the battery electrical drive. Accordingly, the expected prices are at the tank. The experts see e-fuels so only in a niche market for existing vehicles such as vintage cars or motorsports in the "lover" with high willingness to pay.

The vde has also created a forecast starting from a wind turbine with 3 megawatts. Thus, 1600 battery vehicles, 600 with hydrogen and only 250 operate with e-fuels. Nevertheless, that the latter was often considered a kind of longing goal, can only be explained for petri with their simple manageability. In the total cost of ownership, they were much more expensive than battery vehicles.

"The world revolves around the battery"

For petri is clear: "the world revolves around the battery and the fuel cell." especially for the former speak that the developers have already increased the energy density since 1990 already enormously: "we’ll get 100 kilowatt hours in energy today." with the same weight this is significantly more than 30 years ago. From today to 2030 is also a further jump by 30 percent upwards realistic. The costs were at 140 euros per kwh, 2030 at under 70, 2040 at under 50 euros. The battery cell is currently the "effective drive technology" with a rough application field.

The supply security with raw materials sees the vde expert here not really engraved, the geopolitical situation is more problematic. On the other hand, the human rights situation is not only in the minerland congo, but also in olstaaten "sometimes difficult". In addition, on the cathode side of batteries, the early lithium cobalt mixture had been replaced by a growing portion of nickel, so that price lounge could be deterted.

After the startup of the e-mobilitat, recycling will also grab the situation and the situation "buffer", is petri sure. In the okobilance, it is also possible to remove all newer studies that the battery is at least as good as gasoline and diesel. Batteries also had a much gross development potential to significantly reduce their co2 fibe printing using renewable energies.

Technology and ‘made in germany’

According to the analysis, politics now wants to protect the emission-free motivity on technology and use the strong battery electric drive’s batteries and the chances of hydrogen. The economy is mainly due to an expansion of the networks and is reflected in the interest of investment security long-term framework conditions with more wallboxes for burgers at home.

It applies to intensify the societal dialogue and one "positive vision for locally emission-free drive technologies ‘made in germany’" to communicate, is a resumee. Only then konne also the end customer are supported in buying decisions, argued petri. If the burger gets uncertainty, he will continue to wonder why he "go to a battery electric vehicle" should.
