The November revolution of the year 2018 falls on next Thursday, at least for the Hamburger hochbahn AG. The municipal companies did not call less than a “turning point” for their bus.

At Townhall-market, Hamburg’s first mayor, Peter Tschentscher (SPD) wants to present the first electric bus of the country’s biggest tender for such vehicles. From the 4. December, the twelve-Meter-long vehicle is intended to compete with room for 88 passengers to the service, in the normal operation.

Series cars instead of the prototypes

It is the beginning of the end for the diesel buses in many major German cities, the is already. Many municipalities are converting their city buses completely on the electric drive. So you want to improve the air quality and a contribution to climate protection.

Electric City Buses:
Whispering Giant

At the end of July 2018, only 186 of the pure electric city buses for local transport in Germany were operated on-the-go, powered with electricity from battery, fuel cell or an overhead line. It’s not even 0.5 percent of the total of around 40,000 city buses in Germany. And most of the E-buses are operating prototypes in the test.

Mercedes and Solaris provide

The change takes, however, travel. In Hamburg, the first electric buses will come from the serial production on the road. “Mercedes is guaranteed to a range of 150 kilometres under all Weather and application conditions,” says a high-Bahn spokesman. “The buses in our regular rounds.” The high rail with about a thousand buses, the largest fleet in the Hamburg transport Association (HVV).

So far, the company has launched a tender for 60 electric buses, 30 are already ordered. Of Mercedes 20, the Polish manufacturer Solaris ten. From 2020, transport companies can purchase according to a decision of the Hamburg Senate, only emission-free buses. So should be from the beginning of the 2030er years only of such vehicles in the Hanseatic city on the move.

In China, E-buses everyday

The public transport company of the Hanseatic city at the invitation to tender common thing with the Berlin transport companies (BVG), the order of 30 buses. The companies have defined common Standards, and the bus manufacturers so the incentives to develop series production of electric vehicles. On these German cities had waited long in vain. In contrast, battery buses in China for years of everyday life.

“It’s high time that German and European manufacturers are active,” said auto expert Stefan Bratzel of the University of applied Sciences in Bergisch-Gladbach. “The growth is expected to be in the next few years is very high.”

E-buses victories at Hamburg comparison test

So Hamburg had to settle for many years with prototypes of different manufacturers and design. On line 109 vehicles with Diesel-Hybrid, Plug since 2014-in-Hybrid, electric or fuel – cell technology on the road.

The route from Central station to the Alster lake, the village is almost ten miles long, has 23 stops and is used by around 15,000 passengers a day. The out for 109s was, according to the high line, the first bus route in the world, on the systematic city buses with alternative drives under the same conditions were tested.

At the end of the pure electric buses. “Diesel was not in question, and thus all the hybrid were variants of,” says the high line-the speaker. The fuel cell technology is still too expensive.

In Berlin also trolleybuses could come

But also for E-buses mean a huge financial commitment. They currently cost about two to two and a half Times as much as a diesel bus.

Thanks to lower operating costs play the higher investment costs at least partly. Diesel bus and E-Bus hardware, the bottom line is even on a par, calculates the environmental organization Transport & Environment. To do this, however, health care costs would have to be priced in, caused by noise and pollutant emissions.

Berlin establishes, in turn, to pure battery buses. In the capital, could soon drive trolleybuses with battery, which have a larger range. “The revenue is calculated only on lines with a high passenger,” says Thoralf Knote, scientists at the Fraunhofer Institute for traffic and infrastructure systems in Dresden.

First of all, hardly any CO2-saving by electric buses

On the example of Hamburg shows, however, that the environmental effect of electric city buses is limited, even if the electricity is generated for the batteries from renewable energy sources: A diesel bus consumes between 40 and 60 liters per 100 kilometers. Per year, the 1500 buses back in the Hamburg transport Association, about 48 million kilometers. The power, on a rounded average consumption of 50 liters, a reduction in annual CO2 emissions of approximately 63.600 tons.

This corresponds to approximately 1.4 percent of all CO2 emissions, the transport sector emits in Hamburg. After all, any further Expansion of the bus network would increase the effect, insofar as people increasingly leave the car. In addition, the emissions of nitrogen oxides and particulates will drop significantly, expects the Senate of Hamburg.

Buses will be electric, Autonomous

The Federal government of Hamburg at the Bus stop, with 25 million euros. These funds will be directed primarily in the infrastructure. In the district of Alster village, a new depot, where the buses refuel, especially at night power. It is exclusively designed for battery buses, and the first of its kind in Germany.

The change from Diesel to electric drive, Hamburg, and other cities could be only the first step to a completely new transport. The high line starts in February 2019, the test operation with a five-Meter electric minibus on a 3.6-Kilometer-long ring range in the port city. He drives autonomously. No later than 2021 the technology work smoothly. That would be the next Revolution.
