There is no insinuation, it's just a statement of fact. Combustion turbines for 100% hydrogen are not commercially available today. We literally cannot burn 100% hydrogen at scale to provide utility power today.
We may be able to do so in the future, which would be great. Even better if we can do so without emissions and cheaper than other alternatives. But we cannot do so today.
Siemens thinks we can do 100% combustion turbines in about a decade or so. Time will tell. There may be obstacles or maybe everything goes swimmingly.
> And that insinuation is there, or else why did you bring that up?
I brought it up because it is a pertinent detail.
Hydrogen is touted as being the solution to storage for renewables. We are still far from that.
According to https://model.energy/ it might not be such an affordable solution. And even with 100% hydrogen combustion turbines there is the question of storage. Salt caves are cheap, steel storage tanks aren't.
