44.01 secures $5M to turn billions of tons of carbon dioxide to stone
Reducing global greenhouse gas emissions is an important goal, but another challenge awaits: lowering the levels of CO2 and other substances already in the atmosphere. One promising approach turns the gas into an ordinary mineral through entirely natural processes; 44.01 hopes to perform this process at scale using vast deposits of precursor materials and a $5 million seed round to get the ball rolling.
The process of mineralizing CO2 is well known among geologists and climate scientists. A naturally occurring stone called peridotite reacts with the gas and water to produce calcite, another common and harmless mineral. In fact this has occurred at enormous scales throughout history, as witnessed by large streaks of calcite piercing peridotite deposits.
Peridotite is normally found miles below sea level, but on the easternmost tip of the Arabian peninsula, specifically the northern coast of Oman, tectonic action has raised hundreds of square miles of the stuff to the surface.
Talal Hasan was working in Oman’s sovereign investment arm when he read about the country’s coast having the largest “dead zone” in the world, a major contributor to which was CO2 emissions being absorbed by the sea and gathering there. Hasan, born into a family of environmentalists, looked into it and found that, amazingly, the problem and the solution were literally right next to each other: the country’s mountains of peridotite, which theoretically could hold billions of tons of CO2.
Around that time, in fact, The New York Times ran a photo essay about Oman’s potential miracle mineral, highlighting the research of Peter Kelemen and Juerg Matter into its potential. As the Times’ Henry Fountain wrote at the time:
If this natural process, called carbon mineralization, could be harnessed, accelerated and applied inexpensively on a huge scale — admittedly some very big “ifs” — it could help fight climate change.
That’s broadly speaking the plan proposed by Hasan and, actually, both Kelemen and Matter, who make up the startup’s “scientific committee.” 44.01 (the molecular weight of carbon dioxide, if you were wondering) aims to accomplish mineralization economically and safely with a few novel ideas.
First is the basic process of accelerating the natural reaction of the materials. It normally occurs over years as CO2 and water vapor interact with the rock — no energy needs to be applied to make the change, since the reaction actually results in a lower energy state.
“We’re speeding it up by injecting a higher CO2 content than you would get in the atmosphere,” said Hasan. “We have to drill an engineered borehole that’s targeted for mineralization and injection.”

The holes would maximize surface area, and highly carbonated water would be pumped in cyclically until the drilled peridotite is saturated. Importantly, there’s no catalyst or toxic additive, it’s just fizzy water, and if some were to leak or escape, it’s just a puff of CO2, like what you get when you open a bottle of soda.
Second is achieving this without negating the entire endeavor by having giant trucks and heavy machinery pumping out new CO2 as fast as they can pump in the old stuff. To that end Hasan said the company is working hard at the logistics side to create a biodiesel-based supply line (with Wakud) to truck in the raw material and power the machines at night, while solar would offset that fuel cost at night.
It sounds like a lot to build up, but Hasan points out that a lot of this is already done by the oil industry, which as you might guess is fairly ubiquitous in the region. “It’s similar to how they drill and explore, so there’s a lot of existing infrastructure for this,” he said, “but rather than pulling the hydrocarbon out, we’re pumping it back in.” Other mineralization efforts have broken ground on the concept, so to speak, such as a basalt-injection scheme up in Iceland, so it isn’t without precedent.
Third is sourcing the CO2 itself. The atmosphere is full of it, sure, but it’s not trivial to capture and compress enough to mineralize at industrial scales. So 44.01 is partnering with Climeworks and other carbon capture companies to provide an end point for their CO2 sequestration efforts.
Plenty of companies are working on direct capture of emissions, be they at the point of emission or elsewhere, but once they have a couple million tons of CO2, it’s not obvious what to do next. “We want to facilitate carbon capture companies, so we’re building the CO2 sinks here and operating a plug and play model. They come to our site, plug in, and using power on site, we can start taking it,” said Hasan.
How it would be paid for is a bit of an open question in the exact particulars, but what’s clear is a global corporate appetite for carbon offsetting. There’s a large voluntary market for carbon credits beyond the traditional and rather outdated carbon credits. 44.01 can sell large quantities of verified carbon removal, which is a step up from temporary sequestration or capture — though the financial instruments to do so are still being worked out. (DroneSeed is another company offering a service beyond offsets that hopes to take advantage of a new generation of emissions futures and other systems. It’s an evolving and highly complex overlapping area of international regulations, taxes and corporate policy.)
For now, however, the goal is simply to prove that the system works as expected at the scales hoped for. The seed money is nowhere near what would be needed to build the operation necessary, just a step in that direction to get the permits, studies and equipment necessary to properly perform demonstrations.
“We tried to get like-minded investors on board, people genuinely doing this for climate change,” said Hasan. “It makes things a lot easier on us when we’re measured on impact rather than financials.” (No doubt all startups hope for such understanding backers.)
Apollo Projects, a early-stage investment fund from Max and Sam Altman, led the round, and Breakthrough Energy Ventures participated. (Not listed in the press release but important to note, Hasan said, were small investments from families in Oman and environmental organizations in Europe.)
Oman may be the starting point, but Hasan hinted that another location would host the first commercial operations. While he declined to be specific, one glance at a map shows that the peridotite deposits spill over the northern border of Oman and into the eastern tip of the UAE, which no doubt is also interested in this budding industry and, of course, has more than enough money to finance it. We’ll know more once 44.01 completes its pilot work.

As ExxonMobil asks for handouts, startups get to work on carbon capture and sequestration
Earlier this week, ExxonMobil, a company among the largest producers of greenhouse gas emissions and a longtime leader in the corporate fight against climate change regulations, called for a massive $100 billion project (backed in part by the government) to sequester hundreds of millions of metric tons of carbon dioxide in geologic formations off the Gulf of Mexico.
The gall of Exxon’s flag-planting request is matched only by the grit from startup companies that are already working on carbon capture and storage or carbon utilization projects and have announced significant milestones along their own path to commercialization even as Exxon was asking for handouts.
These are companies like Charm Industrial, which just completed the first pilot test of its technology through a contract with Stripe. That pilot project saw the company remove 416 tons of carbon dioxide equivalent from the atmosphere. That’s a small fraction of the hundred million tons Exxon thinks could be captured in its hypothetical sequestration project located off the Gulf Coast, but the difference between Exxon’s proposal and Charm’s sequestration project is that Charm has actually managed to already sequester the carbon.
The company’s technology, verified by outside observers like Shopify, Microsoft, CarbonPlan, CarbonDirect and others, converts biomass into an oil-like substance and then injects that goop underground — permanently sequestering the carbon dioxide, the company said.
Eventually, Charm would use its bio-based oil equivalent to produce “green hydrogen” and replace pumped or fracked hydrocarbons in industries that may still require combustible fuel for their operations.
While Charm is converting biomass into an oil-equivalent and pumping it back underground, other companies like CarbonCure, Blue Planet, Solidia, Forterra, CarbiCrete and Brimstone Energy are capturing carbon dioxide and fixing it in building materials.
“The easy way to think about CarbonCure is we have a mission to reduce 500 million tons per year by 2030. On the innovation side of things we really pioneered this area of science using CO2 in a value-added, hyper low-cost way in the value chain,” said CarbonCure founder and chief executive Rob Niven. “We look at CO2 as a value-added input into making concrete production. It has to raise profits.”
Niven stresses that CarbonCure, which recently won one half of the $20 million carbon capture XPrize alongside CarbonBuilt, is not a hypothetical solution for carbon dioxide removal. The company already has 330 plants operating around the world capturing carbon dioxide emissions and sequestering them in building materials.
Applications for carbon utilization are important to reduce the emissions footprints of industry, but for nations to achieve their climate objectives, the world needs to move to dramatically reduce its reliance on emissions spewing energy sources and simultaneously permanently draw down massive amounts of greenhouse gases that are already in the atmosphere.
It’s why the ExxonMobil call for a massive project to explore the permanent sequestration of carbon dioxide isn’t wrong, necessarily, just questionable coming from the source.
The U.S. Department of Energy does think that the Gulf Coast has geological formations that can store 500 billion metric tons of carbon dioxide (which the company says is more than 130 years of the country’s total industrial and power generation emissions). But in ExxonMobil’s calculation that’s a reason to continue with business-as-usual (actually with more government subsidies for its business).
Here’s how the company’s top executives explained it in the pages of The Wall Street Journal:
The Houston CCS Innovation Zone concept would require the “whole of government” approach to the climate challenge that President Biden has championed. Based on our experience with projects of this scale, we estimate the approach could generate tens of thousands of new jobs needed to make and install the equipment to capture the CO2 and transport it via a pipeline for storage. Such a project would also protect thousands of existing jobs in industries seeking to reduce emissions. In short, large-scale CCS would reduce emissions while protecting the economy.
These oil industry executives are playing into a false narrative that the switch to renewable energy and a greener economy will cost the U.S. jobs. It’s a fact that oil industry jobs will be erased, but those jobs will be replaced by other opportunities, according to research published in Scientific American.
“With the more aggressive $60 carbon tax, U.S. employment would still exceed the reference-case forecast, but the increase would be less than that of the $25 tax,” write authors Marilyn Brown and Majid Ahmadi. “The higher tax causes much larger supply-side job losses, but they are still smaller than the gains in energy-efficiency jobs motivated by higher energy prices. Overall, 35 million job years would be created between 2020 and 2050, with net job increases in almost all regions.”
ExxonMobil and the other oil majors definitely have a role to play in the new energy economy that’s being built worldwide, but the leading American oil companies are not going to be able to rest on their laurels or continue operating with a business-as-usual mindset. These companies run the risk of going the way of big coal — slowly sliding into obsolescence and potentially taking thousands of jobs and local economies down with them.
To avoid that, carbon sequestration is a part of the solution, but it’s one of many arrows in the quiver that oil companies need to deploy if they’re going to continue operating and adding value to shareholders. In other words, it’s not the last 130 years of emissions that ExxonMobil should be focused on, it’s the next 130 years that aim to be increasingly zero-emission.

Noya Labs turns cooling towers into direct air capture devices for CO2 emissions
Not every company’s founders find themselves on a first-name basis with the local bomb squad, but then again not every company is Noya Labs, which wants to turn the roughly 2 million cooling towers at industrial sites and buildings across the U.S. into CO2-sucking weapons in the fight against global climate change.
When the company first started developing prototypes of its devices that attach to water coolers, the company’s founders, Josh Santos and Daniel Cavero, did what all good founders do, they started building in their backyard.
The sight of a 55-gallon oil drum and a yellow refrigeration tank in a sous vide bath attached to red and blue cables didn’t sit so well with the neighbors, so Santos and Cavero found themselves playing host to the bomb squad multiple times, according to the company’s chief executive, Santos.
“We proved that it could capture CO2, and we achieved something that no startup should achieve,” Santos said of the dubious bomb squad distinction.
Santos and Cavero were inspired to begin their experiments with direct air capture by an article describing some research into plants’ declining ability to capture carbon dioxide that Santos read on Caltrain on his way to work back in 2019. That article spurred the would-be entrepreneur and his roommate to get to work on experimenting with carbon chemistry.
Their first product was a consumer air purifier that would pull carbon dioxide from the atmosphere in homes and capture it. Homeowners could then sell the captured gases to Santos and Cavero who would then resell it. But the two quickly realized that the business model wasn’t economical, and went back to the drawing board.
They found their eventual application in industrial cooling towers, which the company’s tech can turn into CO2-capturing devices that have the capacity to take in between half a ton and a ton of carbon dioxide per day.
Noya’s tech works by adding a blend of CO2-absorbing chemicals to the water in the cooling towers. They then add an attachment to the cooling tower that activates what Santos called a regeneration process to convert the captured CO2 back into gas. Once they have captured the CO2 the company will look to resell it to industrial CO2 consumers.
It’s not green yet, at least not exactly, because that CO2 is being recirculated instead of sequestered, but Santos said it’s greener than existing sources of the gas, which come from ammonia and ethanol plants.

“Five years from now we fully intend to have vertically integrated carbon capture and sequestration. Our first step is locally produced low-cost atmospherically captured CO2,” said Santos. “If we were to go all-in on a carbon capture, that would require a lot of time for us to develop. What this initial model allows us to do is fine-tune our capture technology while building up long-term to go to market.”
Santos called it the “Tesla roadster approach” so that the company can build up capital and get revenue and prove one piece of it as an MVP so they can prove other steps of it down the line.
Noya Labs already is developing a pilot plant with the Alexandre Family Farm that should capture between the estimated half a ton and one-ton target.
To develop the initial pilot and build out its team, the company has managed to raise $1.2 million from the frontier tech investment firm Fifty Years, founded by Ela Madej and Seth Bannon, and Chris Sacca’s Lowercarbon Capital (whose mission statement to invest in companies that will buy time to “unf*ck the planet” might be one of the greatest). The company’s also in Y Combinator.
“One of the things that makes us excited about this technology is that in the U.S. alone there are 2 million cooling towers. Looking conservatively — if our initial pilot plant can capture 1 ton per day — we’re at right over half a gigaton of CO2 capture.”
And companies are already raising their hands to pick up the CO2 that Noya would sell on the market. There’s a growing collection of startups that are using CO2 to make products. These companies range from the slightly silly, like Aether Diamonds, which uses CO2 to make… diamonds; to companies like Dimensional Energy or Prometheus Fuels, which make synthetic fuels with CO2, or Opus12, which uses CO2 in its replacements for petrochemicals.
Prices for commercial CO2 range between $125 per ton to $5,000 per ton, according to Santos. And Noya would be producing at less than $100 per ton. Current Direct Air Capture companies sell their CO2 from somewhere between $600 to $700 per ton.
Stoya’s first installation could cost around $250,000, Santos said. For Bannon, that means the company passes his “Mr. Burns test.”
Introducing “the Mr Burns test” for sustainability companies.
Build a product that Mr Burns (the prototypic self-absorbed egoistic greedy capitalist) would buy not because it’s sustainable but because it’s the best / cheapest / most convenient.
That’s the
to impact at scale.

“We’ve been digging into the DAC space but haven’t liked the techno-economics we’ve seen. Previous approaches have had too much capex and opex and not enough revenue potential,” Bannon wrote in an email. “That’s what Noya has solved. By leveraging existing industrial equipment, their model is profitable. And better yet, they make their carbon capture partners money, allowing them to scale this up fast. This creates an opportunity to profitably remove 1 gigaton-plus a year.”
