I'd be stunned if they put a MWh of battery on a plane. This plane in particular only has a range of 120 miles electric-only, so it probably has a pack roughly similar to a modern electric pickup. 200 kWh plus or minus.
By comparison, a regular regional jet probably has around 40 MWh of energy in jet fuel.
Megawatt-hours (MWh) are one billion times larger than milliwatt-hours (mWh).
Thank you for the correction.
IF they end up the size of modern jets, 1MWh is underestimating the need for even an average domestic flight.
Agreed, a full size electric airliner is going to be a different beast entirely. On the bright side, by the time we crack that nut I hope we will be using battery technology with less combustion potential than even LFP.
I don't think there's really any avoiding the combustion potential of that much energy in a compact container. We can maybe hope to make it as safe as jet fuel.
Jetfuel is dense and energetic.
Yes it is. And there's no getting around that, a battery is just chemically-stored energy, the same in that sense as kerosene.
