The electrification of vehicles does not make the car Stop: New drives, hybrid-electric flying today. Norway plans to even the emission-free air travel in the year 2040. How realistic is it and where the problems are?
In Germany has reached the air traffic in the past year, record levels. The demand for aircraft is huge, in order to cope with the increasing passenger numbers. Up to the year 2037, the number of passengers from 2017, is expected to double, according to data of the Airline Association IATA, a minimum of about seven billion. The IATA expects a growth rate of 3.5 percent per year.
In for the industry, a best-case scenario, it will be even 5.5 percent growth, so it would have to be transported in the year 2037 10.3 billion passengers. Although the modern aircraft has become greener and more efficient, this will have consequences for the climate balance.
global development of the passenger
numbers (in billions) Significant topics such as climate change, protection of the environment and noise emissions, create a pressure for innovation in the industry as a whole. And it must not be forgotten that the price of kerosene, one of the largest cost factors in the balance sheets of the airlines. The aviation industry is similar to the car industry in front of a fundamental change? The electric is to fly in the future? The topic is becoming more and more in the focus.
Small jumps with current aviators
The experts of the consulting company Roland Berger deal in various studies extensively with the subject of electric propulsion systems for aircraft. The experts observe that the speed of the development increases. Currently, there are around 100 different development programs. The are 30 per cent more than in 2017 and even a doubling since the year 2016. Around 60 percent of the programs are led by Start-ups, says Roland Berger.
forecasts over periods of time are, of course, with caution. Pretty sure, however, is that the future of electric passenger jets, which fly hundreds of passengers around the globe, is in a further distance. There are still too many unsolved technical problems. Just like with electric cars is the low efficiency of the batteries prevented a larger jump in the air, and especially larger aircraft. Electric aviation is likely to be relatively few seats at the regional level.
“Electric flying becomes a reality”
Easyjet: an electric-aircraft appearance
One of the pioneers in Norway: The country plans to increase the emission-free air travel in the year 2040. From then on, it is possible to operate the domestic flights only with electricity, is the result of a study by the Norwegian airport operator Avinor.
in Germany, Too, has noted the urgency of the issue. In April of last year, Rolf Henke, Executive Board member of the German center for air and space travel, said: “We still need about ten years: five for research and five for development. Then there could be an electrically operated 19-seater.“ First of all, according to Henke, expected to be with Hybrid drive will be flown, that is, a gas will support the electric motor.
The cheap airline Easyjet wants more. She works together with Wright Electric, a Start-up company from Los Angeles, to an electrically-powered passenger aircraft. “Electric flying is a reality, and we see before us a future that does not depend exclusively on kerosene,” says Easyjet Boss Johan Lundgren. In a first stage, to withdraw this year, a common machine, which can transport, with a range of 500 kilometers nine passengers. In perspective, Jets are designed with a significantly larger capacity and range.
outlet in place of kerosene
Airbus E-Fan X: joint project with Siemens and Rolls-Royce
the great aircraft manufacturers are in the starting blocks. The US aircraft manufacturer Boeing has supported the US-Start Up Zunum Aero. The company also wants to build hybrid-electric plane, the US-airline JetBlue Airways is on Board. Zunum would like to bring in the year 2022, a twelve-seater with a hybrid drive on the market.
Airbus is working with Siemens and the British engine manufacturer Rolls-Royce on a joint project. The goal is, by 2020, for the first time, a 100-seater regional aircraft with a hybrid electric powertrain.
Due to the current technical limitations, it is nevertheless still a long way to go to fully electric plane. The experts from Roland Berger estimate that in the early 2030ern first-ever hybrid-powered aircraft with more than 50 passengers in the commercial operation are used. And until the big Jets filling up at the outlet, it will probably take decades rather than years. The auto industry is ahead of the aviation industry so far. But it’s being worked on.
