Houston maintained its No. 3 status this year among U.S. metro areas with the most Fortune 500 headquarters. Fortune magazine tallied 26 Fortune 500 headquarters in the Houston area, behind only the New York City area (62) and the Chicago area (30).

Last year, 23 Houston-area companies landed on the Fortune 500 list. Fortune bases the list on revenue that a public or private company earns during its 2024 budget year.

On the Fortune 500 list for 2025, Spring-based ExxonMobil remained the highest-ranked company based in the Houston area as well as in Texas, sitting at No. 8 nationally. That’s down one spot from its No. 7 perch on the 2024 list. During its 2024 budget year, ExxonMobil reported revenue of $349.6 billion, up from $344.6 billion the previous year.

Houston renewables developer powers 4 new solar parks for Amazon, Microsoft

now open

Houston-based EDP Renewables North America LLC announced that it has powered up four new projects across the country for customers Amazon and Microsoft.

The new projects come about a month after EDP Renewables powered up its new California solar park for Houston-based Shell Energy North America and the Eureka, California-based Redwood Coast Energy Authority.

EDP Renewables announced that it also launched the 100-megawatt Ragsdale Solar Park in Madison Country, Mississippi, in Q4 2024. Amazon has contracted for all 100 megawatts from the solar park through a 15-year power agreement.

The Ragsdale project is the company's second utility-scale project in Mississippi after EDP Renewables launched its Pearl River Solar Park last year.

“Ragsdale signifies EDP Renewables’ ongoing commitment to Mississippi, its communities, and local businesses. The opportunity to develop utility-scale solar and contract directly with customers like Amazon, who are also committed to expanding their own presence in Mississippi, has been invaluable," Sandhya Ganapathy, CEO of EDP Renewables North America, said in a statement. "We are proud to aid the state’s commercial and industrial growth with homegrown energy solutions."

Additionally, EDP Renewables has powered three new projects for tech-giant Microsoft, with two in Illinois and one in Texas.

In December EDP Renewables powered a 150-megawatt Cattlemen II Solar Project in Milam County, Texas, about 70 miles northeast of the Austin area. It joins the 240-megawatt Cattlemen I Solar Park, which came online a year prior.

The company also launched the 140-megawatt Wolf Run Solar Project near Jacksonville, Illinois, and the Hickory Solar Project in Jerseyville, Illinois, late last year. The Hickory project was developed in conjunction with D.C.-based Volt Energy Utility.

Microsoft has agreed to purchase 389 megawatts and renewable energy credits from the projects, which brings the portfolio between the two companies up to five projects in total. It also includes the Timber Road IV Wind Farm located in Payne, Ohio.

"The importance of ensuring benefits flowing from renewable energy development directly into communities has never been more important,” Ganapathy added in a statement. “Through these three additional projects, we’re keeping our promise – and indeed the industry’s promise – to contribute to the nation’s growing energy demand and in that process invest in long-lasting economic growth of our communities.”

Amazon makes investment in direct air capture by way of Houston-based Oxy

Houston-based cleantech company 1PointFive is among the recipients of e-commerce giant Amazon’s first investments in carbon-fighting direct air capture (DAC).

Amazon has agreed to buy 250,000 metric tons of carbon removal credits from Stratos, 1PointFive’s first DAC plant, over a 10-year span. That commitment is equivalent to the amount of carbon stored naturally across more than 290,000 acres of U.S. forecasts, says Amazon.

As Amazon explains, DAC technology filters CO2 from the atmosphere and stores it in underground geological formations. Aside from being stored, removed carbon can be used to make building materials like bricks, cement, and concrete. Read more.

Oxy's cleantech arm scores Amazon DAC investment

carbon capture client

Houston-based cleantech company 1PointFive is among the recipients of e-commerce giant Amazon’s first investments in carbon-fighting direct air capture (DAC).

Financial terms of the deal weren’t disclosed.

1PointFive is a carbon capture, utilization, and sequestration (CCUS) subsidiary of Houston-based energy company Occidental Petroleum.

The carbon captured for Amazon will be stored deep underground in saline aquifers — large geological rock formations that are saturated in saltwater.

1PointFive is constructing its first DAC plant in Ector County, which is anchored by Odessa. The facility is expected to be the world’s largest DAC plant, capturing up to 500,000 tons of CO2 per year. Amazon Web Services (AWS) will provide real-time performance data for the plant.

“Amazon’s purchase and long-term contract represent a significant commitment to direct air capture as a vital carbon removal solution,” Michael Avery, president and general manager of 1PointFive, says in a news release. “We are excited to collaborate with Amazon to help them achieve their sustainability goals.”

1PointFive broke ground on the Stratos plant in April. Its project partners include British Columbia-based Carbon Engineering and Australia-based Worley. The plant is expected to be fully operational by mid-2025.

1PointFive envisions establishing more than 100 DAC facilities around the world by 2035.

The Amazon deal isn’t the only major deal for 1Point5 this summer.

In August, the U.S. Department of Energy (DOE) announced a $600 million grant for a 1PointFive-operated DAC hub that will be built in South Texas. The more than 100,000-acre hub, comprising 30 individual DAC projects, eventually may remove and store up to 30 million metric tons of CO2 per year.

Also in August, Japan’s All Nippon Airways (ANA) said it reached an agreement with 1PointFive to buy 10,000 metric tons of carbon removal credits per year over a three-year period starting in 2025. The credits will be generated by 1PointFive’s Stratos plant.

In the U.S., DAC has gotten a huge boost from the federal government. The Inflation Reduction Act, passed in 2022, includes tax credits for capturing and storing carbon via DAC.

The International Energy Agency says 27 DAC plants have been commissioned around the world, with at least 130 more in the development stage. One forecast predicts the value of the global market for DAC systems will climb past $2.3 billion by 2030.

Houston scientists unveil faster, low-energy method to recycle lithium-ion batteries

Battery breakthrough

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
