“You need to really get to a foot in diameter with a fluidized bed before you get away from wall effects. So if you can get to a foot in diameter or larger, you can get away from wall effects and be very confident that you can take the data that comes out of that and scale it to whatever diameter that you want.”

Opinion
Graphitic claims its process yields the cheapest non-SMR hydrogen at scale
“I mean, it's still, even without any carbon value, if you build a big plant, this is still, we think, the cheapest sort of non-SMR-based hydrogen that you're going to be able to produce.”

Assertion Not checkable as stated
Graphitic Energy produces clean hydrogen for $2 to $3 per kilogram
“You know, I thought that decarbonized hydrogen had to come from an electrolyzer and cost, you know, six or nine dollars a kilogram. You guys can do this for two to three?”

Graphitic Energy sees customer demand for 300,000 tons of carbon annually
“So we think that based on conversations we've had with specific customers that we have demand for 300,000 tons a year as produced from our process going directly into their processes and their customers end uses downstream. First of a kind plant will produce a…”

Opinion
The hydrogen market decline is almost entirely confined to electrolysis
“I think that there's no doubt that there's maybe been a decline in a hydrogen interest, but That's really almost entirely hydrogen from electrolysis.”

Assertion Not checkable as stated
Graphitic's pyrolysis concept required no novel balance-of-plant systems
“And out of that, Came an idea by our technical director of R&D, Sam Shainer, that solved all the challenges of this in a way that required no firsts from a balance of plant perspective.”

Graphitic Energy's graphite byproduct is worth 20x its thermal BTU value
“We remove the carbon As a graphite powder, and for the markets that we have lined up for that, it's worth 20 times its BTU value, so 20 times the amount of money you'd get just for burning that carbon and making CO₂ when we extract it as graphite.”
