Wild Assets Bets Big on Deep Mine Carbon Storage with Rewind Partnership

Carbon removal just got a credibility boost. Global asset manager Wild Assets has signed a long-term offtake agreement to purchase future carbon credits from Rewind's Deep Mine Storage (DMS) project in Georgia. It's a vote of confidence for a technology that's still carving out its place in the carbon removal landscape.

What's the Deal?

Wild Assets, a carbon removal-focused investment firm, will purchase credits generated by Rewind's Georgia facility. The project, which launched in October 2025, is the world's first commercial deep mine carbon storage operation.

The site is expected to hit a storage capacity of 50,000 tons of CO2 equivalent per year by 2027. That's a meaningful number for a technology that's still proving itself at scale.

How Deep Mine Storage Actually Works

The concept is surprisingly elegant. Rewind takes residual timber biomass, basically leftover wood waste, and stores it in decommissioned coal mine chambers. Once inside, the material is stabilized, sealed, and continuously monitored.

Here's the key part: those old mine chambers are naturally oxygen-free. Without oxygen, the biomass can't decompose. And if it doesn't decompose, it doesn't release its stored carbon back into the atmosphere.

The result? CO2 locked away for thousands of years in spaces that were already carved out of the earth.

There's a certain poetry to it. Coal mines that once contributed to carbon emissions are now being repurposed to trap carbon permanently. It's the kind of full-circle solution that makes the decarbonization space exciting.

The Credibility Question

One challenge facing carbon removal projects is proving their credits are legitimate and durable. Wild Assets' investment suggests Rewind has cleared that bar.

The credits from this project are expected to be issued under Isometric's Biomass Storage in Subsurface Mines protocol. That module is currently in public consultation, and Rewind actually contributed to its development. Having a hand in shaping the verification standard while also being evaluated by it shows the company is serious about transparency.

Ram Amar, Rewind's CEO, didn't downplay what this partnership means.

"This offtake means a lot to us. Not only because of its scale, but because it comes from a team we deeply respect, one that brings thoughtfulness, clarity, and strong values to how carbon removal is done," Amar said.

Wild Assets returned the praise. In a statement, the firm noted that Rewind demonstrates "exceptional technological rigor, execution capability, and a deep commitment to quality."

Beyond Georgia

The Georgia project isn't Rewind's only play. The company is also running two Marine Anoxic Carbon Storage (MACS) initiatives. One is located in Romania, and the other operates in the Mediterranean Sea near Israel.

These marine projects use a similar principle. They store organic material in oxygen-depleted underwater environments where decomposition is impossible.

Combined with its deep mine work, Rewind is building a diversified portfolio of carbon storage locations. Each site leverages existing natural conditions to create permanent storage without requiring energy-intensive processes.

The Bigger Picture

Rewind has set an ambitious target: remove one million tons of CO2 annually by 2030. The company plans to achieve this through a global network of deep mines, sediments, and marine basins.

That goal will require significant scaling. But partnerships like the one with Wild Assets provide the capital and market validation needed to get there.

The carbon removal industry is still young. Many technologies remain unproven at scale, and buyers are rightfully cautious about which credits will hold up to scrutiny. Offtake agreements from sophisticated investors signal which approaches are gaining traction.

Deep mine storage is now firmly on that list.

Why This Matters for Decarbonization

Carbon removal needs multiple pathways to reach the scale required for meaningful climate impact. Direct air capture gets most of the headlines, but biomass storage approaches like Rewind's offer a different value proposition.

They're lower-energy. They use existing infrastructure. And they leverage natural conditions that have kept organic material preserved for geological timescales.

None of this means deep mine storage will replace other methods. But it adds another tool to the toolkit. And in the race to pull billions of tons of CO2 from the atmosphere, every viable tool counts.

The Wild Assets partnership is more than a financial transaction. It's a signal that the market is starting to recognize deep mine storage as a credible, scalable solution.

For carbon removal to work, it needs money, verification standards, and real projects in the ground. Rewind now has all three.

The Georgia DMS project represents the first commercial deep mine carbon storage facility in the world, with credits expected to be verified under Isometric's biomass storage protocol.
