What will be the cost of negative emissions sold by Project Vesta in 2030?

Question

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 3333.3 tons of negative emissions from Project Vesta at $75 per ton.

Project Vesta captures CO2 by using an abundant, naturally occurring mineral called olivine. Ocean waves grind down the olivine, increasing its surface area. As the olivine breaks down, it captures atmospheric CO2 from within the ocean and stabilizes it as limestone on the seafloor. They have not publicly set a long-term price target.

This question asks:

On 2030-07-01, what price will Project Vesta charge to permanently capture and store one ton of CO2?

This question will resolve as the price per ton, in $USD charged by Project Vesta for a 1kT purchase, payable immediately, of negative emissions using olivine.

If Project Vesta has merged with or been acquired by a different company, but that company is still selling negative emissions which make use of olivine, this question resolves as the price that company charges.

If neither of the above resolutions are possible, either because Project Vesta has switched to a very different negative emissions technology, or because it no longer exists, this question will resolve as ambiguous.
