Startup behind world’s first hydrogen eVTOL eyes 2025 takeoff
Sirius Aviation has unveiled plans for an eVTOL powered by liquid hydrogen with a range of 1850km — but a capacity of only three people.
What is “hydrogen-electric”? Or is that just a convenient way to call a liquid hydrogen fuelled vehicle an “eVTOL” so you don’t need a new tag on your blog-news site lol
So the marketing material has arrays of electric ducted fan engines and a ton of batteries next to a hydrogen tank. I couldn't find how the hydrogen is being used to charge the batteries.
Hydrogen fuel cell is a thing and can use hydrogen to directly generate electricity with up to 60% efficiency.
Hydrogen energy density seems good on paper, but the storage and fuel cell systems add a lot of weight. That's why all the other electric flight companies are using batteries, they simply perform better.
A 3- and 5-seater? The real question is which will be more expensive: a eVTOL (vertical take off and landing) ride in one of these things, or a supersonic flight?
There's a lot of things that are unclear here.. why is 3 seat Business and 5 Commercial? How does it Vertically Takes-off with only horizontal engines, no jet vectoring or the like? Moreover the article mentions that liquid hydrogen needs to always be at -250C°, which is wrong.
To sum it up, we have a lot of cool renders and little more.
