Equinor makes big investment into lithium projects in Arkansas, East Texas

eyes on LI

A Norwegian international energy company has entered into a deal to take a 45-percent share in two lithium project companies in Southwest Arkansas and East Texas.

Equinor, which has its U.S. headquarters in Houston, has reached an agreement with Vancouver, Canada-based Standard Lithium Ltd. to make the acquisition. Standard Lithium retaining operatorship, while Equinor will support through its core competencies, like subsurface and project execution capabilities.

“Sustainably produced lithium can be an enabler in the energy transition, and we believe it can become an attractive business. This investment is an option with limited upfront financial commitment. We can utilise core technologies from oil and gas in a complementary partnership to mature these projects towards a possible final investment decision,” says Morten Halleraker, senior vice president for New Business and Investments in Technology, Digital and Innovation at Equinor, in a news release.

Standard Lithium retains the other 55 percent of the projects. Per the deal, will pay $30 million in past costs net to the acquired interest. The company also agreed to carry Standard Lithium's capex of $33 million "to progress the assets towards a possible final investment decision," per the release. Additionally, Equinor will make milestone payments of up to $70 million in aggregate to Standard Lithium should a final investment decision be taken.

Lithium is regarded as important to the energy transition due to its use in battery storage, including in electric vehicles. Direct Lithium Extraction, or DLE, produces the mineral from subsurface reservoirs. New technologies have the potential to improve this production method while lowering the environmental footprint.

Earlier this month, Houston-based International Battery Metals, whose technology offers an eco-friendly way to extract lithium compounds from brine, announced that it's installing what it’s billing as the world’s first commercial modular direct-lithium extraction plant located at US Magnesium’s operations outside Salt Lake City. The plant is expected to go online later this year.

M&A Moves

A Norwegian energy company with its United States headquarters in Houston has announced it has acquired a significant chunk of a carbon capture and storage joint venture.

Equinor now owns a 25 percent interest in Bayou Bend CCS LLC, which is reported to be one of the largest domestic carbon capture and storage projects. The project — a JV between Chevron, Talos Energy Inc., and now Equinor, is located along the Gulf Coast in southeast Texas. The terms of the deal were not disclosed.

“Commercial CCS solutions are critical for hard-to-abate industries to meet their climate ambitions while maintaining their activity," Grete Tveit, senior vice president for Low Carbon Solutions in Equinor, says in a news release. "Entering Bayou Bend strengthens our low carbon solutions portfolio and supports our ambition to mature and develop 15-30 million tonnes of equity CO2 transport and storage capacity per year by 2035. Our experience from developing carbon storage projects can help advance decarbonization efforts in one of the largest industrial corridors in the US."

According to Equinor, it purchased its share through the acquisition of Carbonvert's subsidiary, Texas Carbon 1 LLC. Chevron, the operator, holds 50 percent interest, and Talos holds the other 25 percent interest.

“We look forward to working together with our partners to further mature this exciting project. Bayou Bend is Equinor’s first announced low carbon solutions project on the Gulf Coast. Alongside our upstream production and offshore wind developments, we’re strengthening our position as a broad energy company and expanding our footprint in the Gulf region,” Chris Golden, senior vice president and US Country Manager, says in the release. "Bayou Bend is a significant milestone towards growing our low carbon portfolio in the US.”

With about 140,000 gross acres of pore space for permanent CO2 sequestration and over one billion metric tons of gross potential storage resources, according to the release, Bayou Bend is positioned to be one of the largest CCS solutions in the US for industrial emitters.The project spans around 100,000 gross acres across Chambers and Jefferson Counties in southeast Texas, and approximately 40,000 gross acres offshore Beaumont and Port Arthur.

“Delivering lower carbon solutions to harder-to-abate industries is fundamental to Chevron New Energies’ mission, and as a Southeast Texas native, I know how vital these industries are to our local communities and their economies,” Chris Powers, vice president of CCUS at Chevron New Energies, in the release. “We thank Carbonvert for its work on the project, and we look forward to Equinor bringing its expertise and resources to Bayou Bend as it joins the partnership.”

Each of the company's low-carbon innovation arms — Low Carbon Solutions at Equinor, Chevron New Energies division, and Talos Low Carbon Solutions division — are collaborating on the project.

“We continue to make significant progress in developing Bayou Bend, which we believe will be a premier regional carbon storage hub solution for Texas’ largest industrial region. Equinor is a welcomed addition to the partnership. Their experience and track record further enhance the joint venture, which is committed to developing safe, reliable, cost-effective lower carbon solutions while enabling continued economic growth,” said Robin Fielder, executive vice president – Low Carbon Strategy and Chief Sustainability Officer of Talos.

In 2021, Texas General Land Office in Jefferson County, Texas, selected Talos and Carbonvert for the carbon storage lease, located in state waters offshore Beaumont and Port Arthur, Texas. Chevron joined the JV in May 2022. The project expanded earlier this year.

New study shows Houston is still feeling effects of 2014-16 oil crash

lasting impact

A new study from Rice’s Kinder Institute shows that Houston is still feeling the economic effects of the 2014-2016 oil crash, more than a decade later.

Though Houston, nicknamed the Energy Capital of the World, has continued to grow over the time period, the city has still fallen behind other comparable metropolitan areas in earnings and job creation, according to the research. The report is one part of a three-part series that will take a look at regional economic mobility and suggest ideas to expand opportunity.

“When you look at what’s happened in other locations, we’re losing ground,” Flávio Cunha, director of the Center for Economic Mobility at Rice’s Kinder Institute for Urban Research, said in a release. “Our economy is growing, but it’s no longer growing at the rate it used to.”

Global oil prices fell 70 percent between 2014 and 2016, the report said, marking one of the three largest declines since World War II and the longest-lasting downturn since 1986. The report excluded pandemic-related gaps, and it mentions 2017’s Hurricane Harvey as a possible indicator that economic growth stalled after the 2014-2016 oil price crash recovery.

To understand the long-term impact of the crash, researchers compared Houston’s economic performance with 54 metropolitan areas like San Antonio, Pittsburgh and others with less dependence on the energy industry.

Some of the key findings in the report included:

  • Job creation: In 2019, Houston had approximately 240,000 fewer private-sector jobs than similar cities. Employment was 15 percent lower in goods-producing industries and 4 percent lower in the services industries than the control group.
  • Income shifts: Income per resident was 13 percent lower compared to the peer group. Workers who remained employed earned 10 percent less between 2015 and 2019 than in other metros. The 13 percent drop in income equates to roughly $76 billion a year in forgone income, or $10,700 per resident per year in 2025 dollars. The decline was a trend across every age group, education level and sex.
  • Population changes: The rate of people moving to Houston slowed, rather than a surge of people leaving.
  • Hiring changes: Hiring fell sharply for young workers ages 19-24.

Cunha says the most surprising finding was that these trends persisted a decade later. According to the report, by 2024, Houston’s wages and income per resident remained about a fifth and a sixth below those in peer cities, and jobs per resident had continued to lose ground.

“What really surprises me is not that there was this change. It’s that this change has been long-lasting,” he added. “We followed it up to 2024, and we still don’t detect that the economy has recovered from that one shock.”

2 fast-growing energy cos. are finalists for Houston Scaleup of the Year

Meet the finalists

From IPOs to groundbreakings, some of Houston's most innovative companies reached major milestones this year.

As part of InnovationMap's 2026 Houston Innovation Awards, the Scaleup of the Year category honors innovative later-stage startups that have recently reached a significant milestone in company growth. Three scaleups have been named finalists for the 2026 award, two of which are in the energy transition sector.

Read more about these businesses, their founders and their breakthrough technologies below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Erock

Energy infrastructure company Erock, previously known as Enchanted Rock, develops dual-purpose microgrids that rely on natural gas and renewable natural gas to produce lower carbon emissions and air pollutants than diesel generators. Its products can provide bridge power before grid interconnection, backup power during outages and dispatchable capacity that supports long-term grid reliability. The company has more than 1,100 megawatts of installed capacity and over 20 years of experience serving commercial, municipal and large-scale technology customers.

Erock completed its initial public offering this year, raising approximately $600 million in gross proceeds. It also grew its contracted power system sales backlog to approximately $1.7 billion, up tenfold year-over-year, with production sold out through 2028, according to the company's application. The company secured a major equipment order from Anthropic, began construction of the 366-megawatt El Paso Electric project supporting Meta's data center campus, and started assembly operations at its Hyperion facility in Cypress, Texas.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A last month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Venus Aerospace

Spacetech company Venus Aerospace is developing a high-thrust rotating detonation rocket engine (RDRE) that replaces the subsonic combustion used in conventional rocket engines. The RDRE is a compact, simpler engine that can deliver up to 15 percent greater efficiency for defense and space applications. It completed its first U.S. flight test of the engine last summer.

Venus Aerospace was founded in 2020 by CEO Cassie Duggleby and CTO Andrew Duggleby. It raised a $20 million Series A in 2022 and $42 million Series A2 in 2025. It closed a $91 million Series B earlier this year and expanded its leadership team. The company is working toward longer-duration and higher-thrust testing and advancing its flight program.

Oxy inks long-term agreements for 2M tons of CO2 capture, transport

carbon contracts

Houston-based Occidental has made two long-term agreements that will expand its carbon management business in the Delaware Basin and the Permian Basin.

Oxy announced Nov. 9 that it has signed agreements with two unnamed project developers to capture and transport approximately 2 million metric tons of CO2 from their existing and new natural gas processing facilities in the Delaware Basin in West Texas annually. The CO2 will be transported for use in Oxy's enhanced oil recovery (EOR) operations in the Permian Basin.

“Securing reliable, long-term sources of CO2 supports Occidental’s advanced recovery strategy to extend the productive life of existing fields and enhance recovery across our conventional and unconventional resource base,” Vishal Gupta, president and general manager of EOR Ventures at Occidental, said in a news release. “The projects, once operational, will help diversify our CO2 supply, improve access to cost-effective resources and create infrastructure that can connect additional carbon capture projects over time. Federal 45Q incentives are an important support for these investments.”

According to the release, the projects have the potential to expand to handle up to 4 million metric tons of C02 per year combined. The first shipments to Oxy are expected in 2029. The unnamed developers will fund and build the infrastructure to capture, transport and deliver the CO2 to Oxy, the company shared in the release.

Additionally, the agreement stipulates that the projects will also include the build-out of nearly 100 miles of new CO2 pipeline infrastructure. The new pipeline is planned to connect with the existing CO2 pipeline network in the Permian Basin. Oxy adds that the pipelines are being designed to handle additional future capacity to "support future conventional and unconventional recovery opportunities" of CO2.

Oxy uses the EOR process to inject stored CO2 back into a producing oil fields to boost the site's performance. The recycled CO2 displaces trapped oil and gas and is then secured in the reservoir. Oxy says that EOR combined with Direct Air Capture (DAC) technology "remove[s] an amount of CO2 equivalent to that emitted during the production and consumption of [its] products."

Oxy subsidiary 1PointFive is developing a $1.3 billion DAC project in the Midland-Odessa area that is slated to be the largest facility of its kind in the world. Known as STRATOS, it's designed to capture up to 500,000 metric tons of CO2 per year. After a component delay, 1PointFive shared in May that it would ramp up operations at the project throughout 2026.
