ELECTRIC AIRPLANE: THE NEW RENEWABLE ENERGY CHALLENGES

Marco Arezio - Consulente materie plastiche - Electric airplane: the new renewable energy challenges

After cars, motorcycles and electric trains something moves in the field of aeronautics – here is the electric plane –

The electric plane could be the answer to the growing movement ” FlightShame ” (shame of flying) that seeks alternative ways to the plane for small and medium-haul journeys.

There is no doubt that air transport is the most responsible for CO2 emissions in the field of mobility and, the growing flow of passengers that has seen no respite in recent years, does not bode well for air quality.

However, we must also recognize that since 1990 the percentage of CO2 per passenger transported has decreased by 60% despite an increase in passengers equal to 330%, but overall, the increase has been 90%. (read: https://www.plasticare.biz/en/blog/aircraft-pollution-between-truth-and-lies ).

Faced with a compromised environmental situation and due to the fear that airlines may lose passengers, being labeled as serial polluters, solutions are being studied that can make air transport less dependent on fossil fuels and more from renewable energies.

In order to be able to fly an aircraft driven by renewable energy, it is necessary to start from its design, from scratch, since weight and aerodynamics are elements to be taken into great consideration. Therefore, there is ample space for new materials, such as carbon, and for new wing geometries that will have to be less and less impactful on air friction.

Like every new project, a series of steps will be taken that will allow you to reach the desired goal by solving the problems that exist today one by one.

In fact, the first objective will be to be able to use electric airplanes in short distances, up to 500 Km., And then aim for longer distances when battery technology will allow a greater reserve of energy.

In the meantime, Airbus is working on the project of hybrid airplanes , which can also use bio fuels , a probably more immediate response on long distances to electric airplanes . In addition, it has formed an alliance with the American start-up Wright Elettric , for the construction of an engine for an all- electric 9-seater aircraft , after experimenting with some tandem flights.

Test flights are also being conducted in Canada on short routes, with electric airplanes , which can, in the near future, connect the islands near the coast or take tourists to ski resorts.

The first experimental flight covered approximately 160 kilometers (100 miles) with an engine powered by lithium batteries , without creating any kind of problem, in absolute silence and without damaging the environment.
