Some hybrid type of plane should be doable. Take off and climbing takes most of the power plus pure battery flight at altitude would make a huge difference as far as pollution goes. CO2-emissions near ground level are far less of a problem than those at high altitude. To make it viable though we may need upwards of 500Wh/kg and that really is the bare minimum imho.

Totally agree, as charging up thousands of aircraft, tens or hundreds of millions of cars, when most electricity is generated by fossil fuels, may not lower the carbon emission by much. Also most electrical grids are limited in capacity, which would mean charging would have to be "staggered" so that the grid does not collapse. High speed rail would be much more efficient, as high speed electric trains carry more passengers than an electric aircraft.

@@skierpageThe problem is that weight for aircraft is absolutely central. Here we are talking about substituting a fuel that will be like 6 kWh/kg (considering 50% efficiency from fuel to fan rotation) to batteries that are currently 12 times less energy dense. It is not commercially viable except for very short flights and still with decreased load capacity. Indeed the aircraft they want to test this out with will be 8 metric tons ("fuel" included). A Gulfstream G100 series is 6 tons empty and 11 tons full so pretty similar, and can accommodate 6 to 9 passengers flying for 5500km. Consider that in this field costs don't scale linearly: engines that are 1% less efficient means more fuel to be burned, sure, but also means more fuel weight stored for the same distance flown, which means a reduction of load capacity. Overall this amounts to a 3% decrease in revenue for the airline.

Ай бұрын
Took a stab at stats on ChatGPT that look realistic: Let's break down the estimate for the reduction in CO2 emissions if regulations required all flights under 3000 km (approximately 1864 miles) to be electric in the US. Current Short-Haul Flight Statistics: According to various sources, a significant proportion of flights in the US are indeed shorter than 3000 km. Exact statistics can vary, but it's commonly cited that a large majority of flights fall within this range. CO2 Emissions Comparison: Fuel Consumption: Short-haul flights typically use jet fuel, which emits approximately 3.15 kg of CO2 per liter burned. Electric Aircraft: While electric aircraft do not emit CO2 during flight, their electricity consumption and associated emissions depend on the source of electricity generation. Estimating Potential CO2 Reduction: Assuming an average short-haul flight distance and fuel consumption, we can estimate the total CO2 emissions from current short-haul flights in the US annually. Next, estimate how much of that could be replaced by electric aircraft, assuming full adoption under the regulation. Example Calculation (Hypothetical): Hypothetically, if we assume that 70% of US domestic flights are under 3000 km (a common estimate), and if each of those flights emits an average of 1 tonne of CO2 per flight (based on average fuel consumption and emissions factors), then: Total CO2 emissions from these flights annually could be estimated. If all these flights were electric, and assuming zero CO2 emissions from electricity generation (though realistically, there would be some emissions depending on the energy mix), we could estimate the potential reduction. Conclusion: Without exact statistics, a precise tonnage reduction figure is challenging to provide. However, based on rough estimates and assuming a significant portion of flights are affected, the reduction could potentially be substantial, potentially in the millions of tonnes annually. To provide a specific tonnage estimate, one would need detailed flight data and specific emission factors, which are typically available from aviation and environmental agencies for more accurate calculations.

Remember the safety margins that civil aviation have. You are to fly from departure to destination with at most 5% en-route margin, then be able to make an approach, fly to an alternate airport (usually they are about an hour away from each other, too close and you suffer the same bad weather at both airports), be able to hold for 30 min at that alternate. I've been an airline pilot for 18 years flying medium haul flights in Europe, Africa and Middle East, most pilots will take 10-20 min extra fuel and in the winter it could be more to cover for delays with snow-clearance etc.A 3 km runway till take at least 15 min to clear from snow. So as you see a 3000 km range does not mean you can fly 3000 km... short-haul flights are usually turob-propp and they live on very short turn-around times and they use very small amounts of fuel (3-500 kg of fuel) for short trips (1 hour) so the environmental gains from switching to electric flight is very small. These planes are also super cheap to buy and operate so the financial incentive must be substantial for operators to switch. I love electric cars but we have a safety track-record in aviation that is close to perfect, one of the reasons why we have that is because of our ability to carry a lot of extra fuel for the days where the weather is not as agreeable.

When a normal plane needs to make an emergency landing early into a flight, it can dump fuel down to the minimum needed to run the engines until touch-down to reduce landing weight. With a battery-powered plane, the whole plane has to be designed to repeatedly bear the full landing weight under all circumstances. Making the cabin frame strong enough to prevent passengers from getting crushed by batteries in an otherwise survivable crash will require a lot more structure. 500Wh/kg is still only 1/10th the net energy density of most fuels: gasoline is almost 10kWh/kg and with jet engines being ~50% efficient, that is ~5kWh/kg net. Needing 10X as many batteries as you need fuel will severely limit economically viable plane sizes and ranges.

If you look at Europe domestically, little Norway has 3 of the top 10 routes in Europe (since it is really hard to make high-speed trains for the same reason that makes Norway pretty to look at - it is a topographical challenge). 300 km in a straight line can easily take over 7 hours to traverse "overland" due to mountains and fiords. These domestic routes make "Amsterdam-Madrid" or "Paris-Rome" look like struggling routes by comparison. Get aircraft to charge fast enough with a "city-hopper" range of 1000 km and suddenly we are looking at tens of millions of flight hours turned into low emission. I also like what Airbus Helicopters is looking into. Because of what helicopters do (hovering above our heads) we require them to run two turbines over populated areas (like SAR/Ambulance services), both engines needing to be powerful enough to fly away on their own. Airbus is testing out a single jet engine with "5 minutes of battery reserves" in case a second engine is needed for an emergency landing. Hybrid solutions deserve our attention even though Japanese car makers have done their best to soil the concept for a decade.

If 500 Wh/kg give you a range of 3000 km, a rather small further increase to say 600-650 Wh/kg will make your range transcontinental, because passenger jets use 50-60% of the energy to get to their travelling height (~10.000 m). But passenger jets are very expensive and have a lifetime of several decades. So it will take quite a while to replace them.

Much of the requirement for the high altitudes at which commercial aircraft operate is due to the efficiencies of the engines increasing with reduced temperatures. Now, eliminate that factor and, especially for shorter flight distances, the loss of energy due to the climb requirement, might well be substantially rduced.

The test aircraft is 9 tons with the possibility of 18 tons. An Airbus A380 has takeoff weight in excess of 560 tonnes. Can anyone see the discrepancy? As others have mentioned a hybrid aircraft that uses liquid fuels for takeoff, climbing and landing might make some sense in smaller passenger aircraft.

@@MichelVaillancourt Yep we are and no they won't - for a start you have to go back to propellor driven aircraft which are much slower. Then you have to get over the specific energy density of current battery tech. That's the kicker. We've already started to run into theoretical maximums using current anode materials - yes we'll keep tinkering and getting better but for workable heavy aircraft we need 10 - 20x current technology. On top of that another physics problem for heavy aircraft. When you use jet fuel you get considerably lighter as you exchange mass for thrust. That doesn't happen as you transfer electrons. So you're as heavy landing as you were at takeoff. That means you need upgraded landing gear and longer runways. Analogies about previous advancements just don't hold up - because they were all powered by liquid fuels. We could build a hydrogen jet engine tomorrow, but it's a bad idea. Hydrogen has material and storage problems that raise a bunch of safety issues.

As a former pilot (single engine, land) and airplane builder, the attraction of electric flight to me is the enormous increase in reliability and simplicity of an electric motor compared to an internal combustion engine. There is no fire in an electoric motor - no red hot metal banging back and forth. There are literally 100 times fewer moving parts. I don't know if batteries can be made with levels of reliability comparable to the motors. Probably they can, if they aren't there already. But in general a loss of power in an electric airplane should be an order of magnitude less likely than in internal combustion powered planes. And if you do crash an electric plane (or car), there isn't 60 gallons of gasoline splashed all over the place. Survivability of a crash goes way up in those crashes where a fire does not start.

It's long been considered that the energy density required to take all of aviation electric is around 500Wh/kg. We're still a way off but there's a predictable curve for it. But lower densities can permit electrification of the shorter air routes. The other thing to note is that electrification isn't a replace all gas bits with batteries else Tesla wouldn't be able to survive. The car needs to be built around the electric power train from the ground up. The same is true of aircraft. You don't just rip out the fuel tanks (which are structurally part of the wings) and jet engines and just replace them with batteries and motors. Boeing may do this, just as incumbent automakers are doing with cars. They will all go bankrupt. Electric powertrains permits a rethink of aircraft design. As they won't require air (oxygen) to power them, they will be able to fly higher and faster with much greater efficiency than current aircraft.
