Houston-based Envana Software Solutions has received more than $5.2 million in federal and non-federal funding to support the development of technology for the oil and gas sector to monitor and reduce methane emissions.

Thanks to the work backed by the new funding, Envana says its suite of emissions management software will become the industry's first technology to allow an oil and gas company to obtain a full inventory of greenhouse gases.

The funding comes from a more than $4.2 million grant from the U.S. Department of Energy (DOE) and more than $1 million in non-federal funding.

“Methane is many times more potent than carbon dioxide and is responsible for approximately one-third of the warming from greenhouse gases occurring today,” Brad Crabtree, assistant secretary at DOE, said in 2024.

With the funding, Envana will expand artificial intelligence (AI) and physics-based models to help detect and track methane emissions at oil and gas facilities.

“We’re excited to strengthen our position as a leader in emissions and carbon management by integrating critical scientific and operational capabilities. These advancements will empower operators to achieve their methane mitigation targets, fulfill their sustainability objectives, and uphold their ESG commitments with greater efficiency and impact,” says Nagaraj Srinivasan, co-lead director of Envana.

In conjunction with this newly funded project, Envana will team up with universities and industry associations in Texas to:

Advance work on the mitigation of methane emissions
Set up internship programs
Boost workforce development
Promote environmental causes

Envana, a software-as-a-service (SaaS) startup, provides emissions management technology to forecast, track, measure and report industrial data for greenhouse gas emissions.

Founded in 2023, Envana is a joint venture between Houston-based Halliburton, a provider of products and services for the energy industry, and New York City-based Siguler Guff, a private equity firm. Siguler Gulf maintains an office in Houston.

“Envana provides breakthrough SaaS emissions management solutions and is the latest example of how innovation adds to sustainability in the oil and gas industry,” Rami Yassine, a senior vice president at Halliburton, said when the joint venture was announced.

Ohio startup joins Houston clean tech accelerator

onboarding

A clean energy startup has joined Houston-based Halliburton Labs, an incubator for early-stage energy tech companies.

Adena Power, based in Ohio, uses three patented materials to produce a sodium-based battery that delivers clean, safe, long-lasting energy storage. The startup is trying to capitalize on the 100 terawatt-hour potential for energy storage in the U.S. grid.

“With Halliburton Labs’ support and operational expertise, Adena Power looks to accelerate scaling and take advantage of the high-growth market opportunity,” Nathan Cooley, co-founder and CEO of Adena Power, says in a news release.

Adena, founded in 2022, supplies energy storage batteries for the commercial, industrial, and utility sectors. The startup has collected funding from four investors, according to PitchBook: OhioXcelerate, Third Derivative, BRITE Energy Innovators, and For ClimateTech.

Adena’s addition to Halliburton Labs comes during a momentous year for the company. For example:

Adena won the People’s Choice Award at the National Renewable Energy Labs Industry Growth Forum.
Adena earned the MAKE IT (Manufacture of Advanced Key Energy Infrastructure Technologies) Prize from the U.S. Department of Energy.

“Our team is ready to collaborate with Adena to help them accelerate their growth to meet the demand for behind-the-meter storage solutions,” says Dale Winger, managing director of Halliburton Labs.

Halliburton Labs is a wholly owned subsidiary of Halliburton, a provider of products and services for the energy industry. The incubator will have pitches at the inaugural Houston Energy and Climate Startup Week next month.

A new ranking looks at the Houston companies with the most patents granted in 2022. Photo via Getty Images

These are the Houston companies with the most patents granted last year

by the numbers

Two major players in Houston’s energy industry are also major players in the patent arena.

A new ranking from the analytics arm of patent law firm Harrity & Harrity puts Saudi Aramco, whose North American headquarters is in Houston, and Halliburton, whose global headquarters is in Houston, puts them in a tie for the number of U.S. patents with 963 patents received in 2022. Saudi Aramco and Halliburton now share the title of Houston’s patent king.

Saudi Aramco saw a 12 percent rise in patents granted in 2022 compared with 2021, according to Harrity & Harrity’s Patent 300 report, while Halliburton experienced a 5 percent jump. Each company tied for 44th place among the top 300 U.S. patient recipients in 2022.

According to the report, Samsung Electronics (8,513 patents) knocked IBM off its longtime pedestal as the No. 1 recipient of U.S. patents. IBM (4,743 patents) now holds the No. 2 position.

Many of Aramco’s U.S. patents come from its R&D centers in Houston, Boston, and Detroit. The Houston R&D hub opened in 2014 and underwent an expansion three years later.

Aramco, a Saudi Arabia-based supplier of oil and natural gas, also generates patents through academic partnerships, such as the one it established last year with Rice University’s Carbon Hub. Aramco has committed $10 million over five years to the carbon initiative.

“While patents are a leading indicator of innovation, the ultimate goal is to create value through the development of solutions that help to address a particular need,” Aramco says. “Such results are often only possible with significant upfront investments, and patents make it possible to recoup these costs and potentially generate additional revenue through commercialization.”

Last year, Aramco boasted that it ranked first in the oil and gas industry for U.S. patents (864) granted in 2021. Until 2011, Aramco had received only 100 U.S. patents over a 78-year span.

“Many of the patents are for innovations Aramco uses itself for competitive advantage, although they can also be licensed to others, creating extra value for the company,” Jamil Bagawi, then the company’s chief engineer, wrote in 2021.

Halliburton also has ramped up its patenting efforts in recent years.

According to Houston law firm Yetter Coleman, those efforts kicked into high gear after Halliburton lost a fracking patent lawsuit to Tomball-based BJ Services, which is now out of business. In 2003, a Houston jury awarded $98 million in damages to BJ in the case, and Halliburton had to stop selling the system that allegedly infringed on BJ’s patent.

In the five years before the verdict, Halliburton averaged 142 patent awards a year, according to Yetter Coleman. The law firm reported in 2013 that Halliburton subsequently averaged 234 patents a year.

Today, of course, Halliburton has far exceeded those numbers. And it vigorously defends its growing patent portfolio. In September 2022, for instance, three subsidiaries of the oilfield services giant filed two lawsuits against Houston-based rival U.S. Well Services alleging infringement of 14 Halliburton patents.

IAM, a website that reports about the intellectual property industry, noted that when Halliburton sued U.S. Well Services, “IP professionals in the oil and gas industry may well have reached for the popcorn. Battles of this magnitude rarely break out in their slice of the patent world.”

Halliburton and Aramco may be the goliaths in Houston’s patent world, but they’re not the only local organizations to appear on the Patent 300 list for 2022. Other Houston-area companies that made the cut are:

Spring-based Hewlett Packard Enterprise, No. 84. The tech company received 511 U.S. patents in 2022, down 4 percent from the previous year.
Houston-based SLB (Schlumberger), No. 117. The oilfield services company received 372 U.S. patents in 2022, down 14 percent from the previous year.
Houston-based Baker Hughes, No. 123. The oilfield services company received 350 U.S. patents in 2022, down 11 percent from the previous year.
ExxonMobil, No. 156. The oil and gas company received 281 U.S. patents in 2022, down 8 percent from the previous year. It is in the process of moving its headquarters from Irving to Spring.
United Imaging Healthcare, No. 253. The Chinese healthcare equipment company, whose North American headquarters is in Houston, received 175 U.S. patents in 2022, up 31 percent from the previous year.

Houston energy tech incubator names 3 new companies to its program

ready to scale

Halliburton's new in-house incubator program that was announced last year has named three new energy tech startups that are moving in.

Halliburton Labs, which originally launched last summer, was established to promote innovation amidst the energy transition. Member startups will have access to the Halliburton facilities, the company's experts, and its network, and will be located in the company's North Houston headquarters.

"We are excited to welcome a strong group of companies who have demonstrated promising innovation and are working to solve important clean energy challenges," says Dale Winger, managing director of Halliburton Labs, in a news release. "We look forward to collaborating with these companies and providing world-class industrial capabilities and expertise to help them achieve further scale."

Three energy tech startups will join Houston-based Nanotech Inc., the first Halliburton Labs startup in the program. Here are the three selected companies:

Enexor BioEnergy

Tennessee-based Enexor BioEnergy is working to address the world's organic and plastic waste problems. The company has developed a patented bioenergy system that can convert almost any organic, plastic, or biomass waste in any combination, into affordable, renewable power and thermal energy.

"We are seeing tremendous inbound customer demand for Enexor's renewable energy solution from across the world," says Lee Jestings, founder and CEO of Enexor BioEnergy, in the release. "We are honored to join Halliburton Labs. Their broad global network and deep manufacturing expertise will assist Enexor in meeting its significant worldwide demand while making a significantly positive environmental impact. This is a major step forward in our worldwide launch."

Momentum Technologies

Dallas-based Momentum Technologies has created an innovative way to recycle lithium battery by working with recyclers and manufacturers to recover critical materials from waste for reuse. The company was formed through a partnership with the U.S. Department of Energy, and Momentum's patented MSX technology has the ability to recover pure critical materials from spent lithium batteries, rare earth permanent magnets and other valuable waste products.

"Halliburton Labs is the ideal environment to scale our cutting-edge lithium battery recycling technology. We are excited to tap into Halliburton's Labs engineering and supply chain expertise and global business network to accelerate Momentum to the forefront," says Preston Bryant, CEO of Momentum Technologies, in the release.

OCO Inc.

Based in Oregon, OCO Inc.'s technology can transform carbon dioxide, water, and zero carbon electricity into a hydrogen-rich platform chemical that can be used to make a wide variety of zero-carbon chemicals, materials, and fuels. OCO's process is highly carbon negative and much less expensive than existing fossil-based processes and feedstocks.

"The valuable industrial expertise and network of Halliburton Labs will support our build, deployment, and demonstration of a full-size commercial grade system, the next step on our commercialization journey towards an industrial scale plant," says Todd Brix, founder and CEO of OCO Inc., in the release.

Houston startup closes $5M seed round led by Austin VC

Fresh funds

It's payday for a Houston startup that is housed out of the new Halliburton Labs. Nanotech Inc., which material science for fire-proofing and insulation, has announced the close of its $5 million seed round.

According to NanoTech's news release, Austin-based Ecliptic Capital led the investment round. Additionally, the deal also resulted in the conversion of a simple agreement for future equity, or SAFE, that was previously issued to Halliburton Labs.

"The investment from Ecliptic Capital will allow us to scale our business to achieve our mission of fireproofing the world and reducing global energy consumption. Additionally, our participation with Halliburton Labs provides us with the support of a Fortune 500 company." says NanoTech's CEO Mike Francis in the release.

Based in Austin, Ecliptic Capital is a fund focused on early-stage startups and supports a wide range of technologies across neglected geographies and industries.

"Ecliptic is proud to partner with NanoTech as the company's founding institutional investor," says Mike W. Erwin, founder of Ecliptic Capital, in the release. "We're excited to work with the company and leverage our operational expertise to rapidly scale this impactful, world-changing technology. We look forward to a new world where NanoTech accelerates the thermal management market from science-fiction to science-fact."

Halliburton Company chose NanoTech among a round of contenders to be the first participant of their 12-month program located at their Houston headquarters. Halliburton provides Nanotech with its own office space, access to Halliburton facilities, technical expertise, and an extensive network to accelerate their product to market.

'We are thrilled to see a Halliburton Labs participant secure their first round of financing, and congratulate the Ecliptic and NanoTech teams,' says Scott Gale, Halliburton Labs executive director, in the release. 'We are confident in the path forward as they work towards achieving a clean energy future.'

NanoTech's proprietary technology has the ability to be utilized for various industries — including commercial construction, chemical plants, oil and gas, aviation, utilities and much more — for eco-friendly spray-on insulation and fireproofing.

"As a company, we are just scratching the surface on where our technology will be used and can't wait to see the business scale." adds Mike Francis.

Houston startup — buoyed by Halliburton — plans to scale

in the lab

A Houston-based material science startup that uses nanotechnology for thermal insulation and fireproofing has been chosen as the first participant of Halliburton Labs, an innovation incubator, announced late last month by the oil and gas giant.

Halliburton Company chose Nanotech Inc., among a round of contenders to be the first participant of their 12-month program located at their Houston headquarters. Halliburton will provide Nanotech with its own office space, access to Halliburton facilities, technical expertise, and an extensive network to accelerate their product to market.

"With Nanotech's shield material we can have fireproofing infrastructure, saving lives and helping save the planet," says Mike Francis, CEO of Nanotech. "But it's tremendously difficult to scale our small lab to take our product globally, so when we heard about this opportunity with Halliburton Labs, we jumped immediately on it."

Nanotech Inc., started with a singular technology and a simple mission to fireproof the world and reduce energy consumption globally. The base nano shield, flex shield, and forged shield products contain nanoparticles ranging from 1 micrometer to 1 nanometer in a water-based solution with other inorganic compounds. The coating is heat resistant, non-flammable, and the nontoxic properties ensure it is sustainable for the environment.

"We see the Nanotech team as part of our team," says Scott Gale, executive director of Halliburton Labs. "We see them as an extension of the founding Halliburton Labs team, during our initial conversations, we saw their product development cycle and founding team and found a lot of great overlap."

From Francis' perspective, Halliburton Labs allows his company to live the best of both worlds, with access to the garage-style office of any startup and a lab equipped with the full muscle of the Halliburton resources and knowledge.

"What they are providing us is incredible," says Francis. "We have access to this world-class multimillion-dollar laboratory that would take us years to build up, we also have access to our own startup garage. You don't lose the magic of that startup phase, but we also get that bump."

According to Francis, they have already began using the lab to conduct tests that will accelerate the rate to take their nano shield technology to market faster.

"The product stands in and of itself but having access to Halliburton Lab's has changed our trajectory dramatically," says Francis. "If Nanotech had to use a third-party lab, the turnaround would take longer, and many of these tests we have been able to conduct in-house with a one or two-day turnaround."

Nanotech is aiming to move quickly, with its funding process well underway, they expect to reach full capitalization in one or two months. From there they will be looking for a home of their own after they graduate from the incubator, constructing a plant that accommodates their infrastructure and their goals of a global operation. Since the announcement of their participation in Halliburton Labs, many investors have reached out to them.

"By this time next year we'll have our fully operational plant that's going to be able to do hundreds of thousands of tons of product per year," says Francis. "We'll be able to iron out the kinks while we use the Halliburton Labs facilities and figure out what we need in our own lab."

Report: These 10 jobs earn the biggest salary premiums in Texas

A move to Texas bolsters earnings for some, and a new SmartAsset study has revealed the top professions where the median annual earnings in the Lone Star State exceed the national median.

The report, "When it Pays to Work in Texas — and When It Doesn’t," published in April, analyzed over 700 occupations to determine which have the biggest "Texas premium" — meaning jobs where the price-adjusted median annual pay in Texas most exceeds the national median for the same occupation — and which jobs have the biggest “Texas penalty,” where the statewide median annual pay falls furthest below the national median. Salaries were sourced from the U.S. Bureau of Labor Statistics (BLS) and adjusted for regional price parity.

According to the report's findings, geoscientists have the biggest "Texas premium" and make a $159,903 median annual salary. Texas' salary for geoscientists is 61 percent higher than the national median for the same position (after adjusting for regional price parity).

"Texas’s large petroleum industry helps explain why employers in the state retain so many geoscientists," the report's author wrote. "In fact, the Lone Star State is home to more geoscientists than any other state except California."

There are more than 3,600 geoscientists working in Texas, SmartAsset said.

These are the remaining top 10 occupations with the biggest "Texas premiums" (salaries are price-adjusted):

No. 2 – Commercial pilots: $167,727 median Texas earnings; 37 percent higher than the national median
No. 3 – Sailors: $67,614 median Texas earnings; 36 percent higher than the national median
No. 4 – Aircraft structure assemblers: $83,519 median Texas earnings; 35 percent higher than the national median
No. 5 – Ship captains: $108,905 median Texas earnings; 27 percent higher than the national median
No. 6 – Nursing instructors (postsecondary): $100,484 median Texas earnings; 26 percent higher than the national median
No. 7 – Tax preparers: $63,321 median Texas earnings; 25 percent higher than the national median
No. 8 – Chemists: $104,241 median Texas earnings; 24 percent higher than the national median
No. 9 – Health instructors (postsecondary): $128,680 median Texas earnings; 22 percent higher than the national median
No. 10 – Engineering instructors (postsecondary): $129,030 median Texas earnings; 22 percent higher than the national media

The careers where Texas workers earn less

SmartAsset said an editor is the Texas profession where workers earn the furthest below the median for the same occupation elsewhere in the U.S. Not to be confused with film and video editors, BLS defines editors as those who "plan, coordinate, revise, or edit written material" and "may review proposals and drafts for possible publication."

The study found editors make a price-adjusted median wage of $29,710, which is 61 percent lower than the national median for the same position, and there are nearly 8,200 editors in Texas.

It's worth noting that the salaries for editors may be skewed by the fact that there are not major publications in rural areas of Texas, and other professions may also have financial deviations for similar reasons.

Several healthcare jobs also appear to have the worst penalties in Texas compared to elsewhere in the country. Home health aides are the second-worst paying professions in the state, making a median wage of $24,161.

"More home health aides work in Texas than in nearly any other state, with only California and New York employing more," the report said. "However, the more than 300,000 Texans in this occupation earn median annual pay that is about 31 percent below the national median, after adjusting for regional price parity.

SmartAsset clarified that pay penalties are not consistent "across the board" for other healthcare occupations in Texas.

"For physical therapy assistants, occupational therapy assistants, and postsecondary nursing instructors, Texas may be an especially strong place to work, with these occupations offering 'Texas premiums' of between 17 percent and 26 percent," the study said.

These are the remaining top 10 occupations where median annual earnings in Texas fall furthest below the national median for the same occupation:

No. 3 – Cardiovascular technicians: $49,382 median Texas earnings; 27 percent lower than the national median
No. 4 – Semiconductor processing technicians: $38,295 median Texas earnings; 25 percent lower than the national median
No. 5 – Tutors: $30,060 median Texas earnings; 25 percent lower than the national median
No. 6 – Control and valve installers: $56,496 median Texas earnings; 24 percent lower than the national median
No. 7 – Mental health social workers: $46,109 median Texas earnings; 23 percent lower than the national median
No. 8 – Clinical psychologists: $74,449 median Texas earnings; 22 percent lower than the national median
No. 9 – Producers/directors: $65,267 median Texas earnings; 22 percent lower than the national median
No. 10 – Interpreters/translators: $46,953 median Texas earnings; 21 percent lower than the national median

Houston rises in 2026 ranking of best U.S. cities to start a business

Best for Biz

Houston has reaffirmed its commitment to a business-friendly environment and now ranks as the 26th best large U.S. city for starting a business in 2026. The city jumped up eight places after ranking 34th last year.

WalletHub's annual report compared 100 U.S. cities based on 19 relevant metrics across three key dimensions: business environment, access to resources, and costs. Factors that were analyzed include five-year business survival rates, job growth comparisons from 2020 and 2024, population growth of working-age individuals aged 16-64, office space affordability, and more.

Florida cities locked out the top five best places in America for starting a new business: Tampa, Orlando, Jacksonville, Hialeah, and St. Petersburg.

Houston's business environment ranked as the 19th best in the country, and the city ranked 51st in the "business costs" category. However, the city lagged behind in the "access to resources" ranking, coming in at No. 72 overall. This category examined metrics such as Houston's working-age population growth, the share of college-educated individuals, financing accessibility, the prevalence of investors, venture investment amounts per capita, and more.

"From the Gold Rush and the Industrial Revolution to the Internet Age, periods of innovation have shaped our economy and driven major societal progress," the report's author wrote. "However, the past few years have been particularly challenging for business owners in the U.S., due to factors such as the COVID-19 pandemic, the Great Resignation and high inflation."

Earlier this year, WalletHub declared Texas the third-best state for starting a business in 2026, and several Houston-area cities have seen robust growth after being recognized among the best career hotspots in the U.S. Entrepreneurial praise has also been extended to five local companies that were named the most innovative companies in the world, and six powerhouse female innovators that made Inc. Magazine's 2026 Female Founders 500 list.

Texas cities with strong environments for new businesses
Multiple cities in the Dallas-Fort Worth Metroplex can claim bragging rights as the best Texas locales for starting a new business. Dallas ranked highest overall — appearing 11th nationally — and Irving landed a few spots behind in the 16th spot. Arlington (No. 23), Fort Worth (No. 30), Plano, (No. 35), and Garland (No. 65) followed behind.

Only six other Texas cities earned spots in the report: Austin (No. 24), Lubbock (No. 36), Corpus Christi (No. 39), San Antonio (No. 64), El Paso (No. 67), and Laredo (No. 76).

Austin tied with Boise, Idaho and Fresno, California for the highest average growth in the number of small businesses nationally, while Corpus Christi and Laredo topped a separate list of the U.S. cities with the most accessible financing.

Houston humanoid robotics startup taps Amazon veteran to lead manufacturing

new hire

Persona AI, a Houston-based startup that’s developing AI-powered humanoid robots for manufacturers and other businesses, has hired Brian Davis as head of global manufacturing.

Davis previously guided teams at Amazon Robotics and Dell Technologies. During his tenure at Amazon Robotics and Dell, both companies saw major increases in manufacturing volumes within a four-year period. Davis oversaw manufacturing, supply chain, logistics, quality assurance and real estate.

“Davis steps into this role [at Persona AI] as industrial enterprises face an urgent and accelerating challenge: a structural shortage of capacity for welding, fabrication, and heavy maintenance in dynamic environments, precisely the high-value, high-risk tasks where humanoid robots can deliver the greatest impact,” according to a company news release.

Davis comes aboard as Persona AI, founded in 2024, seeks to meet demand generated by deals with HD Hyundai and POSCO Group to make humanoids for shipyards and steel plants, and by a pilot program with the State of Louisiana.

“Now is the perfect time to accelerate our production capabilities as we rapidly close the gap between what’s possible in the lab versus what’s driving real commercial value,” Davis says.

“Building industrial-rated humanoid robots and production-deployable AI is only one piece of the puzzle,” he adds. “Producing humanoids at scale will require systematic supply chain management, stringent quality control, and building the playbook for safe, high-volume manufacturing. That’s what I’m here to build.”

Last year, Persona AI raised more than more than $10 million in pre-seed funding. The company also named a new head of commercial strategy in March.
