Will CarbonCure still exist in 2030?


Stripe, a financial-services company, committed last year to spending at least $1M/year on negative emissions and carbon storage technologies, at any price, with the aim of helping these technologies develop.

They recently wrote up a summary of their first set of these purchases.

This miniseries aims to predict the success of the companies that Stripe chose.

Stripe has purchased 2500 tons of carbon storage from CarbonCure at $100 per ton. Note that unlike two of the other companies in the series, CarbonCure does not capture CO2 directly, it sequesters CO2 which has already been captured by some other method.

CarbonCure sequesters CO2 in concrete by mineralizing it into calcium carbonate (CaCO3). This has the side effect of strengthening the concrete.

This question asks:

On 2030/7/1, will CarbonCure still be selling carbon storage using broadly similar technology to their 2020 approach?

This question resolves positive if this question has an unambiguous resolution. Otherwise, it resolves negative.
