Why The Airbus A320 Will Never Be All Electric

Last Wednesday Rolls Royce and Airbus gave an update on the E-Fan X project. The briefing was held in Paris and, interestingly, the topic of an all-electric Airbus A320 came up.

Many companies are currently working on integrating hybrid and electric designs into their aircraft. The goal of this is to make aviation cleaner, in an age when carbon emissions are of increasing concern. So far, initiatives range from Ampaire’s hybrid Cessna 337, which will enter production, to Airbus’ E-Fan X which is being used instead for research and proof of concept.

All-electric Airbus A320

An all-electric Airbus A320 would be a wonderful thing. Why? Fasten your seatbelts as we’re about to encounter some very rough maths.

On an average flight, Ryanair emits of around 66g of CO2 per passenger per km. There are 189 seats on a Boeing 737, and Ryanair’s January load factor was 91%. This would mean there were approximately 172 passengers on board, giving us 11.35kg of CO2/km for the flight. Roughly.

Ryanair operates over 600,000 flights a year, according to their website, so you can see how their carbon footprint begins to add up. According to the BBC, Ryanair alone are responsible to 10,000,000 tonnes of CO2 per year, or 10 megatonnes. YouSustain says that’s equivalent to driving a car nonstop for almost 45,000 years!

While the A320neo claims to be 15% more efficient than the ceo version, it’s still responsible for a sizeable carbon footprint, particularly when you imagine more than 8,000 of the A320 family have been delivered to date.

Taking that CO2 out of the equation or reducing it significantly by making the A320 an electric aircraft would clearly be a great thing to do. However, Airbus say it just won’t work.

Why won’t an all-electric Airbus A320 work?

When answering questions regarding the E-Fan X project in Paris Airbus’ Chief Technology Officer, Grazia Vittadini, spoke on a theoretical all-electric Airbus A320

Vittadini told how currently lithium-ion batteries have an energy density of 100 Watt Hours per Kilogram. She explained that, “assuming for a moment that we’d be able to rely on batteries 30 times as energy dense as that [100wh/kg], an A320 would be able to fly with half of its payload for one-fifth of its current range, 500nm max. So, assuming a battery which today does not exist … It doesn’t work, purely electrical will not work.”

What is the solution?

Currently, the future is reliant on more efficient gas turbine engines. However, aircraft and engine manufacturers are devoted to solving the issue of aircraft emissions. Some of the avenues being explored are hybrid aircraft, while others are about making aircraft engines more electric. An example of a more electric engine could see the mechanical starter on the accessory gearbox being replaced by an electric starter.

Indeed, earlier this month, we discussed a Bloomberg report on the matter. Industry insiders had noted that Airbus want to develop the world’s first hybrid electric airliner, a version of the A320neo. This would be hybrid and not all-electric though.

As she said, without breakthrough in batteries there will be no electric plane. Not even hybrid. Maybe as a show off(like tesla). Hybrid is using recuperation when you are using brakes, planes are not using brakes, only when they are landing they can brake with some turbines, but will this energy at least be able to transport batteries that will be on the plane?
I don’t think so.

The whole concept of powering a jet airliner with batteries is purely political, and is totally beyond reach. Why? Jet fuel has an insane amount of energy per Kilogram, and a battery cannot hope to even get close.

Do you not think this could change in the future? We’ve gone from electric cars being a pipedream that would never work to there being millions on the roads all over the world… perhaps technological advances will bring us (large) electric aircraft in the future too? Eviation already have a 9 seat all-electric aircraft capable of 600 miles flight, so who knows what the future will bring?


Cars aren’t a good example. Cars powered by reciprocating engines don’t have the efficiency of a turbine engine. High-bypass turbofans exponentially increase this efficiency. Turbine engines are too expensive to use in a commercially sold vehicle. Lithium batteries are a dead end. There is not enough lithium for any large battery demand. They are also not very thermally stable. Look at all the Tesla battery fires. Not acceptable on a airliner. These “E-Fan” projects are fantasy, to get good PR. It doesn’t cost them much money to attach an electric motor to a fan and show press photos of how… Read more »

So what about Eviation Alice? You don’t think that’s an example of technology moving forward?

As far as I know, Tesla has about 150Wh/kg at the pack level right now which could increase by 20-40% within about 5-10 years. That’s considerably higher than what this article states. Yes it’s nowhere near enough for something like an A320 but apparently even current battery technology is enough for a 9-seater with 600 miles of range.

Joanna Bailey

Yep, we’re looking into Eviation Alice shortly. Battery technology has come a long way; I can imagine in the next decade we’ll see some incredible advancements that could lead the way to an all-electric A320.
