Really inspiring to see some progress in this area. Capturing in cement is indeed pretty clever! I wish you the best of luck to scale up production.

#12You're talking about ancillary products and regulatory credits, which is a fine business model; but I'm asking about the core industrial process. Trying to get a sense of how much more efficient your scale-up needs to be, before your process is in the black.

#13How many orders of magnitude separate your current cost per ton of limestone from the popular status quo methods?

#14What do you find to be your greatest challenges when marketing to existing partners in this space? From an engineering perspective, it seems to be a "no brainer", but I'm curious to hear the push back or objections (if any) you've received.
Existing players have all been overwhelmingly positive! From their perspective we're not competing with their core business and they don't have to change any of their existing plants to use our product. All they have to do is buy from us rather than a mining company to get carbon neutral cement. The main push-back is the need to perform testing on the product to make sure they udnerstand performanc before integrating…

Our current cost per tonne is in the same order of magnitude when including the carbon value from the European ETS. The key success criteria for making large plants profitable will be connecting to cheap electricity at <$50/MWh we're in the black

#16I really like the idea. One thing I'm curious about is what's in it for the contractors (edit: cement producers) buying from you instead of others? I get the environmental impact, but my guess is they only care if touches their bottom line. Will it be cheaper, either in raw price or because of green incentives etc?

What is the current price of carbon credits in the ETS? I am from the USA / am dumb, so don’t know how to find it Also good read for everyone: https://www.gatesnotes.com/Energy/Introducing-the-Green-Prem...

#19Curious about the name, my immediate thought (and interest making me click in) was that it sounds Norwegian. Any connection? I really like the idea.

Our experience so far has been that the environmental angle has been sufficient to persuade. Cement companies are in a bit of a bind given the attention to their sustainability efforts. However we're pitching ourselves as a cost competitive solution. Depending on geography we'll be able to positively affect their bottom line through the carbon credits system. Under the European ETS for example, they reward companies that reduce emissions (https://carbonmarketwatch.org/wp/wp-content/uploads/2016/11/...)
