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 university to launch artificial intelligence major, one of first in nation

BS in AI

Rice University announced this month that it plans to introduce a Bachelor of Science in AI in the fall 2025 semester.

The new degree program will be part of the university's department of computer science in the George R. Brown School of Engineering and Computing and is one of only a few like it in the country. It aims to focus on "responsible and interdisciplinary approaches to AI," according to a news release from the university.

“We are in a moment of rapid transformation driven by AI, and Rice is committed to preparing students not just to participate in that future but to shape it responsibly,” Amy Dittmar, the Howard R. Hughes Provost and executive vice president for academic affairs, said in the release. “This new major builds on our strengths in computing and education and is a vital part of our broader vision to lead in ethical AI and deliver real-world solutions across health, sustainability and resilient communities.”

John Greiner, an assistant teaching professor of computer science in Rice's online Master of Computer Science program, will serve as the new program's director. Vicente Ordóñez-Román, an associate professor of computer science, was also instrumental in developing and approving the new major.

Until now, Rice students could study AI through elective courses and an advanced degree. The new bachelor's degree program opens up deeper learning opportunities to undergrads by blending traditional engineering and math requirements with other courses on ethics and philosophy as they relate to AI.

“With the major, we’re really setting out a curriculum that makes sense as a whole,” Greiner said in the release. “We are not simply taking a collection of courses that have been created already and putting a new wrapper around them. We’re actually creating a brand new curriculum. Most of the required courses are brand new courses designed for this major.”

Students in the program will also benefit from resources through Rice’s growing AI ecosystem, like the Ken Kennedy Institute, which focuses on AI solutions and ethical AI. The university also opened its new AI-focused "innovation factory," Rice Nexus, earlier this year.

“We have been building expertise in artificial intelligence,” Ordóñez-Román added in the release. “There are people working here on natural language processing, information retrieval systems for machine learning, more theoretical machine learning, quantum machine learning. We have a lot of expertise in these areas, and I think we’re trying to leverage that strength we’re building.”

Houston biomanufacturing accelerator adds pilot plant to support scale-ups

new digs

Houston accelerator BioWell announced this month that it has taken over operations of Texas BioTechnology’s pilot plant in Richmond, Texas.

The 33,000-square-foot facility is one of the largest of its kind in the U.S. and features molecular biology labs, advanced automation, fermentation equipment and 16 dedicated benches for early-stage industrial biomanufacturing companies, according to a release from the company. It will allow BioWell to offer on-site education, workforce development, and lab training for students and workers.

BioWell and its founding company, First Bight Ventures, report that the facility should help address the industry's "scale-up bottleneck due to limited pilot- and demonstration-scale infrastructure" in the U.S.

"As a Houston-based accelerator dedicated exclusively to early-stage biomanufacturing startups, partnering with this facility was a natural and highly strategic decision for us. The site is fully operational and offers a strong platform to support biomanufacturing companies, industry leaders, and research institutions, providing critical expertise and infrastructure across a broad range of biotechnology production processes,” Veronica Breckenridge, founder of First Bight Ventures and BioWell, said in a news release.

First Bight Ventures shares that the partnership with the facility will also allow it to better support its portfolio companies and make them more attractive to future investors.

BioWell will host an open house and tours of the fermentation and lab spaces and an overview of current bioindustrial projects Wednesday, May 28, at 10:30 a.m. and 2 p.m. RSVPs are required.

BioWell was originally funded by a $700,000 U.S. Economic Development Administration’s Build to Scale grant and launched as a virtual accelerator for bioindustrial startups. Listen to an interview with Carlos Estrada, head of venture acceleration at BioWell, here.
