The key feature of hydrogen as energy storage wouldn't necessarily be round trip efficiency but cost effectiveness (compared to batteries) of long-term storage over months. Think a…

There's apparently scientific studies that show how animals as well as humans tend to continue eating until they've satisfied a mostly fixed daily need for protein, mostly regardle…

Storing it in batteries works for short periods of up to maybe a few days. You don't think there will be seasonal mismatch between renewable generation and electricity demand? Beca…

It says ~ 2 kWh/kg (kg of iron) according to [1]. Assuming you can just store it as piles of iron dust (somehow shielded from air/oxygen) and assuming a gross density of 5 t/m³ for…

Methane appears convenient at first glance, yes. Can be burnt in regular turbines, stoves, even some cars. But is it really the overall best way to store hydrogen? Methane has a ra…

Duh. > The challenges are immense. Hydrogen fuel is expensive — as much as four times more expensive than gasoline or diesel fuel. What a trash opening of an article about technolo…
