Houston-based Mati Carbon has won the $50 million grand prize in the XPRIZE Carbon Removal competition, backed by Elon Musk’s charitable organization, The Musk Foundation.

Mati was selected in 2024 as one of 20 global finalists. The company removes carbon through its Enhanced Rock Weathering (ERW) program that works with agricultural farms in Africa and India.

The 3-year-old startup accelerates the natural process of rock weathering (ERW) by applying pulverized basalt to croplands of partnered smallholder farmers, free of charge. Mati says the farmers it partners with are some of the most vulnerable to the impacts of climate change.

“Winning this XPRIZE competition is an incredible honor and a definitive validation of our research and development, and building out the infrastructure needed to impact millions of farmers while delivering verifiable carbon dioxide removal at a gigaton scale,” Mati Carbon Founder and CEO Shantanu Agarwal, said in a news release. “I couldn’t be prouder, not just of the Mati team, but of our collaborators, research partners and the thousands of smallholder farmers who let us be part of their lives. This XPRIZE recognition will allow us to collaborate with local partners to accelerate the use of enhanced rock weathering across the Global South.”

Mati reports that it plans to use the award to “scale its efforts working with smallholder farmers worldwide.” Apart from the XPRIZE funding, Mati plans to grow its model through the sale of CDR credits. According to the company, it counts Shopify, Stripe, and H&M among its early carbon credit buyers.

“Mati Carbon’s deployments bolster farmers’ livelihoods through improved soil health, reduced agricultural inputs, and increased income at zero cost to them. Mati Carbon’s team has developed a scientifically rigorous approach to monitoring and verification, and excelled across each of XPRIZE’s prize evaluation criteria – operational, sustainability, and cost metrics – giving the XPRIZE judges the highest confidence in Mati Carbon’s solution’s long-term scalability,” the XPRIZE judges wrote.

Houston-based Vaulted Deep took home the second-runner-up prize in the competition and $8 million for its organic waste storage process. The company provides permanent carbon storage by injecting nonhazardous organic waste deep underground. It spun off with $8 million in seed funding from Advantek Waste Management Services in 2023.

"Our approach is grounded in geomechanical injection techniques that have been safely deployed globally for decades by our team and predecessors," Omar Abou-Sayed, co-founder and executive chairman of Vaulted, said in a separate release. "XPRIZE recognized that this is a proven approach—already in use, delivering impact, and built on the kind of reliability the industry needs to scale responsibly."

Launched in 2021, the four-year XPRIZE Carbon Removal competition challenged global innovators to deploy scalable solutions for removing carbon dioxide from the atmosphere and oceans. More than 1,300 teams from 88 countries competed. XPRIZE finalists were required to remove at least 1,000 tonnes of CO2 over a one-year demonstration period.

French company NetZero took home the first-runner-up prize of $15 million, and London-based UNDO came in as third-runner-up with a $5 million prize.

Since the announcement of the XPRIZE Carbon Removal competition, the Musk-led Department of Government Efficiency has cut climate funding for agencies, projects and research. While the Musk Foundation sponsored the XPRIZE event, it is not affiliated with the California-based organization, according to the Associated Press.

Houston agriculture robotics co. raises $21.5M series A to grow climatetech solution

freshly funded

A Houston energy tech startup has raised a $21.5 million series a round of funding to support the advancement of its automated technology that converts field wastes into stable carbon.

Applied Carbon, previously known as Climate Robotics, announced that its fresh round of funding was led by TO VC, with participation from Congruent Ventures, Grantham Foundation, Microsoft Climate Innovation Fund, S2G Ventures, Overture.vc, Wireframe Ventures, Autodesk Foundation, Anglo American, Susquehanna Foundation, US Endowment for Forestry and Communities, TELUS Pollinator Fund for Good, and Elemental Excelerator.

The series A funding will support the deployment of its biochar machines across Texas, Oklahoma, Arkansas, and Louisiana.

"Multiple independent studies indicate that converting crop waste into biochar has the potential to remove gigatons of CO2 from the atmosphere each year, while creating trillions of dollars in value for the world's farmers," Jason Aramburu, co-founder and CEO of Applied Carbon, says in a news release. "However, there is no commercially available technology to convert these wastes at low cost.

"Applied Carbon's patented in-field biochar production system is the first solution that can convert crop waste into biochar at a scale and a cost that makes sense for broad acre farming," he continues.

Applied Carbon rebranded in June shortly after being named a top 20 finalist in XPRIZE's four-year, $100 million global Carbon Removal Competition. The company also was named a semi-finalist and awarded $50,000 from the Department of Energy's Carbon Dioxide Removal Purchase Pilot Prize program in May.

"Up to one-third of excess CO2 that has accumulated in the atmosphere since the start of human civilization has come from humans disturbing soil through agriculture," Joshua Phitoussi, co-founder and managing partner at TO VC, adds. "To reach our net-zero objectives, we need to put that carbon back where it belongs.

"Biochar is unique in its potential to do so at a permanence and price point that are conducive to mass-scale adoption of carbon dioxide removal solutions, while also leaving farmers and consumers better off thanks to better soil health and nutrition," he continues. "Thanks to its technology and business model, Applied Carbon is the only company that turns that potential into reality."

The company's robotic technology works in field, picking up agricultural crop residue following harvesting and converts it into biochar in a single pass. The benefits included increasing soil health, improving agronomic productivity, and reducing lime and fertilizer requirements, while also providing a carbon removal and storage solution.

"We've been looking at the biochar sector for over a decade and Applied Carbon's in-field proposition is incredibly compelling," adds Joshua Posamentier, co-founder and managing partner of Congruent Ventures. "The two most exciting things about this approach are that it profitably swings the agricultural sector from carbon positive to carbon negative and that it can get to world-scale impact, on a meaningful timeline, while saving farmers money."

Twenty promising climatetech companies were selected to advance to the final stage of a global competition backed by Elon Musk's foundation — and three of the finalists hail from Houston.

Vaulted Deep, Mati Carbon, and Climate Robotics secured finalists spots in XPRIZE's four-year global competition is designed to combat climate change with innovative solutions. XPRIZE Carbon Removal will offer $100 million to innovators who are creating solutions that removes carbon dioxide directly from the atmosphere or the oceans, and then sequester it sustainably.

"For the world to effectively address greenhouse gas emissions, carbon removal is an essential element of the path to Net Zero. There's no way to reverse humanity's impact on the climate without extracting carbon from our atmosphere and oceans," Anousheh Ansari, CEO of XPRIZE, says in a news release. "We need a range of bold, innovative CDR solutions to manage the vast quantities of CO2 released into our environment and impacting our planet.

"The teams that have been competing for this Prize are all part of building a set of robust and effective solutions and our 20 teams advancing to the final stage of XPRIZE Carbon Removal will have an opportunity to demonstrate their potential to have a significant impact on the climate," Ansari continues.

The finalists — categorized into four sections: air, rocks, oceans, and land — were selected based upon their performance in three key areas: operations, sustainability, and cost. The full list of 20 finalists is available online.

Around 20 Houston-area companies were initially identified by the challenge. Here's a look at the three that are advancing to the finals:

  • Mati, in the Rocks category, durably removes carbon from the atmosphere using basalt based enhanced rock weathering (ERW) in smallholder rice paddy farms. This process, which is being demonstrated in India, removes atmospheric CO2 while adding key nutrients in the soil helping to restore degraded soils to benefit smallholder farmers.
  • Climate Robotics, in the Land category, enables broad-scale agriculture adoption of biochar which builds soil health and removes excess carbon from the atmosphere. The company's mobile technology converts crop residues into durable biochar on the fly and in the field, making the economics work for farmers and our ecosystems.
  • Vaulted Deep, also in the Land category, delivers scalable, permanent, carbon removal by geologically sequestering carbon-filled organic wastes. Their patented slurry sequestration, which involves the geological injection of minimally processed wastes for permanent (10,000+ year) carbon removal.

"This cohort of exceptional teams represents a diversity of innovations and solutions across a range of CDR pathways, and shows the significant progress the industry is making in a short period of time," Nikki Batchelor, executive director of XPRIZE Carbon Removal, says in the release. "Over the past three years, this competition has helped accelerate the pace of technology development for a whole new industry of high-potential solutions aimed at reversing climate change."
