Aviation: the green stuff – coming soon to an airfield near you | daryanenergyblog

Already a number of electric planes are entering the market. Most of these early entrants are short range light aircraft intended for use as trainers, or for general aviation use. For light aircraft the benefits of an electric power train offer a significant advantage, while the main downside (range) is less of an issue, as trainers rarely stray particularly far from their home airfield. There is something of a price premium to be paid, as they are slightly more expensive than a similar piston powered aircraft. But the fuel efficiency savings (the major cost of ownership of any plane tends to be fuel) would presumably reduce the burden of those costs.

And some companies see these light aircraft as a natural stepping stone towards larger aircraft flying perhaps commercial flights with fare paying passengers and cargo.One concept for example, is the Ce-Liner. This will use ducted fan electric motors powered by Li-Ion batteries. Should you be wondering how long does it take to recharge all those batteries (and how many coffee’s does the pilot need to drink while he waits), well the batteries are mounted on standard cargo pallets, the same ones used to carry air-freight and luggage in. This means the amount of batteries the aircraft carries can be lowered as necessary (freeing up space for more cargo), improving fuel economy on shorter flights.
