There are a couple demonstration projects in UK where final effluent is used as feedstock for the hydrogen and the oxygen is pumped back into the treatment plant.

That's funny! I suppose they defined it room electricity source?! Weird.

I think that might be difficult to quantify as 'fail' could mean anything from delayed, on pause, cancelled, or didn't work. The country which is progressing well I reckon it's Germany!

🤔 I don't think they're anti-hydrogen. Everything comes at a cost. I'm researching into water supply for h2 & there's concern here in Scotland about scarcity... And it bloody rains most days haha I can share some papers if interested! Good news, there are ways around it... Or I'm working on it 😊 🦾

Where are they getting the hydrogen from? Which country has the infrastructure?

I'm not familiar with the tech. Does the process of CC not involve some sort of particulate filtering?

Interesting. I wondering how long it takes to charge battery... My understanding was that was a key barrier in battery use.
