Wideroe (Norway) has set up the goal to become 100% electric by 2030. Avinor (Norwegan airports operator) wants all domestic flights to become 100% electric by 2040. What are these vikings know which we don't?
My point is that the air transport aircraft will rely on fossil fuels for the foreseeable future except for small regional types. Wideroe has a number of Dash 8 turboprops and it is conceivable but unlikely that these could be replaced by electric-powered types by 2030. There are numerous current projects for electrically-powered small commuter-type aircraft of up to 12 seats plus projects to modify the smaller Dash 8s to take electric power and I'm sure that that's what Wideroe intend to do - very short sectors with batteries regularly topped up with abundant hydro-electric power. However, they recently became the launch operator of the Embraer E190-E2 - a 114 pax jet which will be in service with them well beyond 2030 which kind of acknowledges the fact that larger electrically-powered aircraft aren't there yet.
