ADAC study: Rural infrastructure not yet ready for e-mobility-e-mobility

In view of the fact that by 2020 around 500.000 cars with electric drives are supposed to be on the road, two years later already a million electric cars, a number of questions are raised. Among other things, there is the question of whether our power grids can withstand the additional load and where investments in the infrastructure have to be made. It is important to note that e-mobility should not only be possible in urban areas, but also in small towns and rural areas.

The ADAC Foundation has taken this as the occasion The study “Analysis of a coordinated infrastructure structure for the supply of battery and fuel cell vehicles in Germany” of the Ludwig-Bolkow Foundation, which from October 2017 to May 2019 together with Ludwig-Bolkow-Systemtechnik GmbH and the Institute of Institute Applied System Technology (AST) of the Fraunhofer IOSB was carried out to promote.

The focus of the study is the calculation of the infrastructure costs for the introduction of 40 million zero-emission cars in Germany by 2050. The interaction of the infrastructure for battery and fuel cell cars is interesting here. The study examines this in three scenarios, each with different proportions of vehicle technologies. In doing so, metropolitan areas, small and suburban areas as well as rural areas were examined and the need for network expansion was calculated.

“Against the background of climate and health protection, all low-emission vehicle technologies must be taken into account. Since the aim of the climate protection plan 2050 of the Federal Government can not be achieved for road traffic from the point of view of experts with purely battery-powered vehicles, we have considered the infrastructure demand for both battery and fuel cell technology: “- DR. Andrea David, Board Member of the ADAC Foundation

Furthermore, David is of the opinion that the scientific study by the Ludwig Bolkow Foundation would like to make a contribution to ensuring that the infrastructure in Germany is fit for electromobility based on renewable energies in good time. As part of the study, it became apparent that “more must be invested in small towns, the suburbs of large cities and in rural areas.“ The increasing demand for electricity in particular will be more noticeable there; because commuters will use the network more than before.

It is also noticeable that the grids in the periphery and in rural areas are weaker, since there is often a large number of companies with high daily electricity consumption, as Dr. Werner Zittel, Chairman of the Ludwig Bolkow Foundation, explained the most important results of the study. The fuel cell would be a perfect complement to battery technology.

A positive effect here would be that there would be no additional bottlenecks in the electricity distribution network as a result of hydrogen filling stations. The main expansion requirement for electricity distribution networks can be postponed and reduced through the parallel expansion and use of hydrogen, Zittel continues. The parallel use, i.e. a mix of 50 percent battery and fuel cell-powered vehicles, also has a positive effect in terms of costs. Up to six billion euros could be saved per year.

The savings are due, among other things, to the fact that many individual charging points have to be set up for purely electric cars. Refueling with hydrogen would be possible at larger and more cost-efficient filling stations. The study therefore speaks the “recommendation for politics, municipalities and business, the expansion of the infrastructure for electricity and hydrogen in good time, parallel and coordinated to advance,” continues David.

  1. The fuel cell drive based on hydrogen production using electrolysis requires 3 times as much electricity as a BEV, which will never pay off economically.
    Why is this not taken into account by the study ? Because it doesn’t fit the image of the study commissioner ?

  2. Without a doubt, storing the electrical energy directly in the battery is the more effective use and should be used to the greatest possible extent. If electricity is also generated from wind or solar energy, hydrogen is a good additional storage medium. The efficiency is put into perspective if this energy were not used alternatively or wasted. Incidentally, our fuel is only used to about 1/4 in typical car driving today. 3/4 The energy is implemented in heat and the resulting CO2 emission goes into the atmosphere without having to do something meaningful. The 2/3 losses in the hydrogen have at least no CO2 burden.
    For the reloading of energy on long distances, hydrogen would be ideal and would only be very available. Better than all electric fast loaders.
    Why not use the advantages of both systems and z.B. Expand cars for long distances additionally with hydrogen and fuel cell as a rangeextender. For commercial vehicles, hydrogen has a very different importance.
    I see in the article. No “daily report”!

  3. Hydrogen drive is not an alternative to improving the charging problem in rural areas . Also electricity has enough there. Especially on newer farms strong power lines are installed where to do without problems
    3 Loading Phases quickly. In addition to inns and hotels, there are also weaker power lines there, there is usually more time available to load.(Overnight)
