1PointFive secures new buyer for Texas CO2 removal project

seeing green

Houston’s Occidental Petroleum Corp., or Oxy, and its subsidiary 1PointFive have secured another carbon removal credit deal for its $1.3 billion direct air capture (DAC) project, Stratos.

California-based Palo Alto Networks has agreed to purchase 10,000 tons of carbon dioxide removal (CDR) credits over five years from the project, according to a news release.

The company joins others like Microsoft, Amazon, AT&T, Airbus, the Houston Astros and the Houston Texans that have agreed to buy CDR credits from 1Point5.

"Collaborating with 1PointFive in this carbon removal credit agreement highlights our proactive approach toward exploring innovative solutions for a greener future,” BJ Jenkins, president of Palo Alto Networks, said in the release.

The Texas-based Stratos project is slated to come online this year near Odessa. It's being developed through a joint venture with investment manager BlackRock and is designed to capture up to 500,000 metric tons of CO2 per year. The U.S Environmental Protection Agency recently approved Class VI permits for the project.

DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted. Under the agreement with Palo Alto Networks and others, the carbon dioxide that underlies the credits will be stored in a below-the-surface saline aquifer and won’t be used to produce oil or gas.

“We look forward to collaborating with Palo Alto Networks and using Direct Air Capture to help advance their sustainability strategy,” Michael Avery, president and general manager of 1PointFive, said in the release. “This agreement continues to build momentum for high-integrity carbon removal while furthering DAC technology to support energy development in the United States.”

4 Houston energy companies named best places to work by U.S. News

Where to Work

Nearly a dozen public and private Houston-based companies have been hailed among the best places to work in 2025 by U.S. News and World Report, with four from the energy sector.

The annual "U.S. News Best Companies to Work For" report examines thousands of publicly-traded companies around the world to determine the best employers based on six metrics including work-life balance and flexibility; quality of pay and benefits; job and company stability; career opportunities and professional development; and more. The companies were not ranked, but included based on reader surveys and publicly available data about each workplace.

New for the 2025-2026 ratings, U.S. News expanded its methodology to include privately owned companies and companies with internship opportunities for recent graduates and new, current, and prospective students. Companies were also grouped into job-specific and industry-specific lists, and the publication also added a new list highlighting "employers that are particularly friendly to employees who are also caregivers in their personal lives."

U.S. News included seven publicly-traded companies and four privately owned companies in Houston on the lists.

Houston-based energy companies on the list

It may not come as a surprise that oil and gas corporation Chevron landed at the top of the list of top public employers in the Energy Capital of the World. The energy giant currently employs more than 45,000 people, earns $193.47 billion in annual revenue, and has a market cap of $238.74 billion. The company earned high ratings by U.S. News for its job stability, "belongingness," and quality of pay.

Chevron also appeared in U.S. News' industry-specific "Best in Energy and Resources" list, the "Best Companies in the South" list, and the "Best for Internships" list.

Chevron is joined by three other Houston energy leaders:

Calpine – Best in Energy and Resources; Best Companies (overall)
ConocoPhillips – Best in Energy and Resources; Best Companies (overall); Best in Caregiving; Best Companies in the South

Men's Warehouse – Best in Consumer Products; Best Companies (overall)
PROS – Best in Information Technology; Best Companies (overall); Best Companies in the South
Skyward Specialty Insurance – Best in Finance and Insurance; Best Companies (overall); Best Companies in the South

"'Best' is a subjective term relative to career satisfaction, and many aspects factor into someone’s decision to apply for a job with any given company," U.S. News said. "But some universally desired factors can contribute to a good workplace, such as quality pay, good work-life balance, and opportunities for professional development and advancement

In all, 30 employers headquartered in the Lone Star State made it onto U.S. News' 2025-2026 "Best Places to Work For" lists. Houston and the Dallas-Fort Worth metro area tied for the most employers make the list, at 11 companies each. Diamondback Energy in Midland was the only company from West Texas to make it on the list for the second year in a row.

Oxy opens energy-focused innovation center in Midtown Houston

moving in

Houston-based Occidental officially opened its new Oxy Innovation Center with a ribbon cutting at the Ion last month.

The opening reflects Oxy and the Ion's "shared commitment to advancing technology and accelerating a lower-carbon future," according to an announcement from the Ion.

Oxy, which was named a corporate partner of the Ion in 2023, now has nearly 6,500 square feet on the fourth floor of the Ion. Rice University and the Rice Real Estate Company announced the lease of the additional space last year, along with agreements with Fathom Fund and Activate.

At the time, the leases brought the Ion's occupancy up to 90 percent.

Additionally, New York-based Industrious plans to launch its coworking space at the Ion on May 8. The company was tapped as the new operator of the Ion’s 86,000-square-foot coworking space in Midtown in January.

Dallas-based Common Desk previously operated the space, which was expanded by 50 percent in 2023 to 86,000 square feet.

CBRE agreed to acquire Industrious in a deal valued at $400 million earlier this year. Industrious also operates another local coworking space is at 1301 McKinney St.

Industrious will host a launch party celebrating the new location Thursday, May 8. Find more information here.

Oxy subsidiary granted landmark EPA permits for carbon capture facility

making progress

Houston’s Occidental Petroleum Corp., or Oxy, and its subsidiary 1PointFive announced that the U.S Environmental Protection Agency approved its Class VI permits to sequester carbon dioxide captured from its STRATOS Direct Air Capture (DAC) facility near Odessa. These are the first such permits issued for a DAC project, according to a news release.

The $1.3 billion STRATOS project, which 1PointFive is developing through a joint venture with investment manager BlackRock, is designed to capture up to 500,000 metric tons of CO2 annually and is expected to begin commercial operations this year. DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted. Major companies, such as Microsoft and AT&T, have secured carbon removal credit agreements through the project.

The permits are issued under the Safe Drinking Water Act's Underground Injection Control program. The captured CO2 will be stored in geologic formations more than a mile underground, meeting the EPA’s review standards.

“This is a significant milestone for the company as we are continuing to develop vital infrastructure that will help the United States achieve energy security,” Vicki Hollub, Oxy president and CEO, said in a news release.“The permits are a catalyst to unlock value from carbon dioxide and advance Direct Air Capture technology as a solution to help organizations address their emissions or produce vital resources and fuels.”

Additionally, Oxy and 1PointFive announced the signing of a 25-year offtake agreement for 2.3 million metric tons of CO2 per year from CF Industries’ upcoming Bluepoint low-carbon ammonia facility in Ascension Parish, Louisiana.

The captured CO2 will be transported to and stored at 1PointFive’s Pelican Sequestration Hub, which is currently under development. Eventually, 1PointFive’s Pelican hub in Louisiana will include infrastructure to safely and economically sequester industrial emissions in underground geologic formations, similar to the STRATOS project.

“CF Industries’ and its partners' confidence in our Pelican Sequestration Hub is a validation of our expertise managing carbon dioxide and how we collaborate with industrial organizations to become their commercial sequestration partner,” Jeff Alvarez, President of 1PointFive Sequestration, said in a news release.

1PointFive is storing up to 20 million tons of CO2 per year, according to the company.

“By working together, we can unlock the potential of American manufacturing and energy production, while advancing industries that deliver high-quality jobs and economic growth,” Alvarez said in a news release.

Houston startup raises $6M to grow AI platform for solar, battery contractors

fresh funding

Houston tech startup Artemis has raised $6 million from 10 investors. The company offers an AI-supported platform that enables solar, battery storage and home improvement contractors to design, sell and finance energy projects.

Long Journey and Copec WIND Ventures co-led the round, with participation from angel investor Scott Banister, Coalition Operators, FJ Labs, Ludlow Ventures, Palm Tree Crew, Plug and Play Ventures, Shrug Capital and Tribeca Ventures.

To help propel growth, the company secured $10 million in financing last year (under its previous name, Monalee) from venture debt and growth credit provider Applied Real Intelligence. As Monalee, the company raised $16 million in venture capital.

The company was founded in 2022 as an installer of solar and battery storage projects. Five years later, the startup used in-house technology to establish its standalone software platform as it began pivoting away from installation. The company recently adopted the Artemis brand name.

Artemis says its platform saves time and money for installers of residential solar, battery storage, and energy projects. The platform combines an AI-powered design tool with embedded financing capabilities and compliance automation to create a single operating system.

The company says its customers report as much as a 72 percent reduction in software costs and up to 98 percent faster turnaround times. Thus far, more than 100 installers are using Artemis’ technology.

“Installers shouldn’t need six tools and a week of back-and-forth to sell a project," Walid Halty, co-founder and CEO of Artemis, said in a press release. “This funding gives us the fuel to scale our mission to compress design, financing, and compliance into a single flow so every installer can operate like a modern energy company. We’re not just speeding up deals, we're modernizing how distributed energy gets built.”

The Artemis platform, now available in the U.S. and soon to be launched in Latin America, caters to home improvement contractors, solar companies, lenders, and utilities.

“Artemis is transforming the complexity of distributed energy into elegant simplicity," added Arielle Zuckerberg, general partner at Long Journey.

Houston researchers propose model to scale e-waste recycling

critical research

The “missing link” in critical minerals may have been in our junk drawers all along, according to new research from the University of Houston.

Jian Shi, an associate professor in the UH Cullen College of Engineering, and his team have unveiled a new supply chain model that aims to make e-waste economically viable and could help make large-scale recycling possible.

Shi, along with professor Kailai Wang and graduate researcher Chuyue Wang, published the work in a recent issue of Nature. Their study outlines how gold, lithium and cobalt from discarded electronics can be kept circulating in the U.S. through the process of “urban mining.” It was supported by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) through the Vehicle Technologies Office.

The team’s research found that e-waste is the fastest-growing solid waste stream in the world. When waste from smartphones or tablets is left unmanaged, the devices can leak hazardous waste and pose significant fire risks due to aging batteries. Additionally, when they are shipped off to foreign landfills, the U.S. loses the potential to recycle or reuse the critical minerals left inside.

“A lot of people have iPads or old iPhones sitting in their drawers right now, and that’s a waste of a critical resource,” Shi said in a news release. “Urban mining allows us to extract the same high-value materials found in traditional mines without the environmental destruction. More importantly, it helps secure our domestic supply chain for the technologies of tomorrow.”

According to UH, recycling e-waste has not succeeded in the U.S. due to a fragmented recycling system, in which manufacturers, collectors and recyclers operate separately, driving up costs.

The UH team's research looks to change that.

In the study, the researchers modeled streamlined recycling efforts by mapping the interactions between manufacturers and independent recycling markets. Their dual-channel closed-loop supply chain (CLSC) model identified how these players can transition from competitors to partners, which can distribute profits more equitably and make recycling efforts more financially attractive.

According to UH, the research has particular significance due to the growing demand for electronic vehicles and their batteries.

“We can improve the performance of the entire recycling ecosystem and make the profit distribution more balanced,” Wang said in the release. “This ensures that the materials we need for EVs and advanced electronics stay right here in the U.S.”

“By making recycling work at scale, we aren’t just cleaning up waste,” Shi added. “We’re building a foundation that benefits both our national security and our economy.”

1PointFive signs latest deal, shares update on $1.3B carbon removal project

DAC deal

Houston-based 1PointFive, a subsidiary of Occidental Petroleum Corp., has secured another buyer of carbon dioxide removal credits for its $1.3 billion STRATOS project as it moves toward operation.

Bain & Company, a Boston-based consulting firm, has agreed to purchase 9,000 metric tons of carbon dioxide removal (CDR) credits from the direct air capture (DAC) facility over three years, according to a news release. DAC technology pulls CO2 from the air at any location, not just where carbon dioxide is emitted.

The deal is Bain's first purchase of DAC removal credits. The company has developed a program that helps clients purchase carbon credits from a range of carbon-removal technologies.

"We are proud to partner with 1PointFive and add them to our portfolio of engineered carbon removal technologies," Sam Israelit, Bain’s chief sustainability officer, said in the news release. "Their track record for developing DAC technology, coupled with their deep understanding of what it takes to deliver large-scale infrastructure projects, uniquely positions them to be a leader in this emerging segment.”

“We believe this agreement demonstrates continued momentum for the solution while supporting the development of vital domestic infrastructure,” Anthony Cottone, president and general manager of 1PointFive, added in the release.

Bain joins others like Microsoft, Amazon, AT&T, Airbus, the Houston Astros and the Houston Texans that have agreed to buy CDR credits from STRATOS.

The Texas-based STRATOS project is being developed through a joint venture with investment manager BlackRock and is designed to capture up to 500,000 metric tons of CO2 per year. The U.S Environmental Protection Agency approved Class VI permits for the project last year.

1PointFive says STRATOS is "progressing through start-up activities." The company shared in a LinkedIn post that Phase 1 of the project is expected to go online in Q2, with Phase 2 ramping up through the remainder of 2026.
