Does this stuff live up to the hype? It's been getting a lot of play on pop-sci websites.

quick rundown on the hype?
I must have lived under a rock...

This honestly sounds insanely promising and much more practical than a hydrogen fuel cell

https://www.electrive.com/2021/02/02/fraunhofer-develops-hydrogen-storage-paste/

>According to the Fraunhofer researchers, the refuelling process is straightforward. Instead of driving to a filling station, the scooter driver changes a cartridge and fills tap water into a water tank. In the vehicle itself, the paste is pressed out of the cartridge and mixed with a precisely measured amount of water, depending on the required power. This reaction produces gaseous hydrogen, which can then be converted into electricity for the electric motor.

Biggest issue with hydrogen fuel cells is that it's literally a bomb you're sitting on. This is probably much safer than that and if the power density claims are true, much more marketable.

It still feeds into fuel cell, its just stored chemically instead of as a pure gas inside a pressure vessel

Sounds like all the other pop-sci future fuels. It'll fade out of existence because none of the advantages are worth the tradeoffs.

>The Fraunhofer scientists even say that the driver should achieve a similar range with the power paste extrapolated to a car as they would with the same amount of petrol, if not greater.

>This should go into operation at the end of 2021 and then produce up to four tonnes of power paste per year

So 4000kg a year, that's a little more than 10kg a day. So 10kg of petrol a day out of an entire factory. This shit's gonna cost $4500 a kilo

Is it literally just MgH2 and water? No binder, PEG, stabilizers and shit?

>Gaseous hydrogen
This sounds a lot more fucking dangerous than hydrogen bombs. If you would inhale that gas you could immediately run into acidosis, wouldn't you?

probably just a pilot reactor at this point. wouldn't call that a factory

how much energy does the process take?

i believed hydrogen to be a bad alternative until this paste
i already posted about it in /o/
the biggest question is how much it will cost to be a true alternative for everyone
it´s also unknown where all the magnesium is supposed to come from to make enough paste for enough people

entire countries are betting on hydrogen (germany) to be the future and until now hydrogen was a shit choice. it is unsafe to handle and a crash can end in a fireball or explosion. a huge pressure tank was also needed. now a german institute developed this paste that only releases the hydrogen at a very high temperature so it´s safe to use AND it has a way bigger hydrogen concentration than the gas itself. it can store 10 times the energy of a battery and this is fucking huge. the hype is real but where do you get the magnesium for it? how much will it cost to be competitive? there are still questions to be answered but this paste is fucking amazing

why magnesium? why not calcium?
Aluminum?
