All of Norway’s short-haul airliners should be entirely electric by 2040, the country’s airport operator said on Wednesday, cementing the Nordic nation’s role as a pioneer in the field of electric transport.

Avinor, the public operator of Norwegian airports, “aims to be the first in the world” to make the switch to electric air transport, chief executive Dag Falk-Petersen said.

“We think that all flights lasting up to 1.5 hours can be flown by aircraft that are entirely electric,” he said, noting that would cover all domestic flights and those to neighbouring Scandinavian capitals.All of Norway’s short-haul airliners should be entirely electric by 2040, the country’s airport operator said on Wednesday, cementing the Nordic nation’s role as a pioneer in the field of electric transport.

“We think that all flights lasting up to 1.5 hours can be flown by aircraft that are entirely electric,” he said, noting that would cover all domestic flights and those to neighbouring Scandinavian capitals.Electric air travel will also at least halve noise levels and the operating cost of aircraft, Falk-Petersen said.

But before reaching that point, Avinor said it would need to use intermediary technologies, such as biofuels and hybrid fuel-electric solutions.

Boeing and Airbus are currently exploring the viability of electric aircraft.

After abandoning a project for 100% electric planes last year, Airbus decided to refocus its efforts on developing a hybrid model, signing a partnership with British engine maker Rolls Royce and German industrial group Siemens. The first flight is planned for 2020.

Zunum Aero, a start-up partly financed by US aeronautics group Boeing, plans to bring a hybrid plane to the market by 2022.
