Goodbye, flying shame.
Currently, every person on this planet is experiencing the abnormal and drastic weather changes caused by global warming. It is easy to imagine the future that awaits. In order to stop global warming and leave the Earth as green as possible by reducing greenhouse gases such carbon dioxide, which is the main cause of global warming. In Germany, under the “Climate Change Action Plan 2050”, which aims to reduce carbon dioxide emissions to virtually zero by 2050. “Green Hydrogen” generates hydrogen with electricity derived from renewable energy will be newly introduced. It looks promising as a power source. A major European aircraft maker – Airbus, has announced plans to develop an aircraft that flies with hydrogen fuel as its main power source by 2035. When it is put into practical use, it will be the world’s first zero-emission (zero greenhouse gas emission) commercial aircraft.
According to Airbus’ announcement, the following three types of concept machines have been released, and the name “ZEROe” is given to mean zero emissions.
● Turbofan design (120-200 seatings)
ruising range of over 2000 nautical miles and is capable of intercontinental flight. Power is obtained by burning hydrogen in an improved gas turbine engine instead of jet fuel. Liquid hydrogen is stored in a tank installed behind the rear pressure bulkhead.
● Turboprop design (up to 100 seatings)
Cruising range is over 1000 nautical miles. Uses a turboprop engine instead of a turbofan. Power is obtained by burning hydrogen in a gas turbine engine.
● Blended wing body design (up to 100 seatings)
Cruising range of 2000 nautical miles or more, which is about the same as the turbofan design. Since the main wing and the fuselage are integrated and the fuselage has a wide range of specifications, various choices can be made depending on the hydrogen storage / supply method and the layout of the cabin.
Demand has plummeted worldwide due to the spread of the new coronavirus, and business conditions continue to be difficult, but Airbus CEO Guillaume Fori said, “A historic moment for the commercial aircraft industry. Airbus will play a leading role in the most important transition to date, “said an ambitious comment.
In order to put it to practical use, it will require enormous costs such as infrastructure development for refueling at the airport, but it should be done to keep the Earth green.
