Sublime Systems

“Sublime's process has, produces a cement that has the same embodied energy as Portland cement today.”

“So, you know, we don't use a thermal process in the kiln. So, you know, we don't have 1500 degrees Celsius, and therefore we don't make that tricalcium silicate phase that's only stable at that temperature. But we still make, in the end, that calcium silicate …”

“This means that we can use calcium carbonate, in which case, when the calcium is extracted, we're left with pure, cold, compressed CO₂, so inherently captured CO₂ that's ready to go into a pipeline or to be used in food grade applications, a very low cost of c…”

“So we, you know, work with Microsoft. That's one of you know, the announcements that Sublime made recently is an MOU signed with Microsoft and to buy the environmental attributes of some of our cement.”

“There is a 45 Q tax credit for, you know, it's like 80 dollars a ton for removing CO₂ from a flu stack, and we don't have that.”

“You know, we've got this grant from OSED. It's eighty-seven million dollars for our industrial demonstration program.”

“What Sublime is doing is technology-enabled carbon avoidance. Our competitor is post-combustion carbon capture.”

“So Sublime Systems, where I'm an investor, is so far, I think, pulling off this really complex value chain integration, as well as anybody, but They're building a large commercial demonstration plant in Holyoke, Massachusetts, and they've announced a bunch of …”

“So, this idea of using low-cost electricity in an electrolyzer to produce acid and base allows you to produce acid and base for chemical reactions that then follow. And those chemical reactions can be done on a volume basis, and in fact, you can decouple in te…”
