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.

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 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."

UH med school granted $2M gift to offer student scholarships

scholarship gift

A new scholarship endowment aims to support students in the University of Houston’s recently established medical school.

The University of Houston’s Tilman J. Fertitta Family College of Medicine received a planned estate gift commitment estimated at $2.1 million to establish the Bob Diehl and Teresa Evans Diehl Scholarship Endowment. The scholarship will assist full-time medical students who demonstrate financial need and meet academic standards.

“Endowed scholarships like this do more than ease the burden of tuition—they empower our students to focus on learning, leadership and compassionate care,” Jonathan McCullers, UH vice president of health affairs and dean of the Fertitta College of Medicine, said in a news release. “We are deeply grateful to the Diehls for their vision and commitment to expanding access to health care through education.”

The endowment aims to provide annual scholarship support for students enrolled in the Fertitta College of Medicine. The gift also aligns with the university's fundraising initiative focused on expanding opportunities for students, known as Can’t Stop Houston: The Centennial Campaign, which works to expand research ahead of UH’s 100th anniversary next year.

The Diehls are both graduates from UH, and Bob Diehl spent 38 years working at UPS.

“It brings me happiness to know that my endowment will make a difference in young people's lives and in the communities that will need those future doctors,” he said in the release.

The Fertitta College of Medicine welcomed its inaugural class of 30 students in 2020 and expects classes to grow to 120 students in the coming years, according to UH. The university believes scholarship opportunities will be crucial for students to pursue medical education despite financial challenges.

“The Diehl family’s generosity will open doors for talented future physicians who are called to serve our communities but may otherwise face financial barriers to pursuing a medical education,” McCullers added.

Houston medtech firm secures $30M for neurosurgical robot

stroke surgery

Robotic neurosurgery is an exciting new frontier in medicine, and Houston-based medtech firm XCath is leading the charge with its revolutionary Iris robotic system. The company announced in March that it had secured $30 million in Series C funding to continue developing systems to tackle blood clots in the human brain.

“We are grateful to our investors for their conviction in our shared mission to improve clinical outcomes for patients impacted by endovascular diseases,” Eduardo Fonseca, CEO of XCath, said in a news release. “In 2025, the XCath team advanced the frontiers of endovascular robotics. This funding accelerates our commitment to expanding access to life-saving care so that where a patient lives no longer determines whether they live.”

XCath–which also has campuses in Pangyo, South Korea–has already achieved a number of remarkable firsts in robotic neurosurgery. The Iris is the only endovascular robotic system currently in development to perform intracranial navigation or neurointerventional treatment, and is the only robot in the world to have performed an intracranial neurovascular procedure involving the robotic manipulation of three devices.

These new Series C funds, which bring the company's total investment to $92 million, will go toward developing a clinical telerobot capable of performing a mechanical thrombectomy. This would bring unprecedented accuracy and precision to the surgical removal of brain clots, significantly reducing the risk of neurosurgery.

“Robotic surgery succeeds when innovation is paired with practical execution,” Dr. Fred Moll, chairman of the XCath board of directors, said in the release. “XCath has built a promising technology foundation, and just as importantly, a team that values rigor and appreciates perspective. I’m excited to support them as they take on the mission of globalizing access to gold-standard care for stroke patients.”

In November 2025, the Iris debuted under the control of Dr. Vitor Mendes Pereira at The Panama Clinic in Panama City, alongside local Principal Investigator Dr. Anastasio Ameijeiras Sibauste. It was only the second time in human history that a robot had been used for intracranial neurovascular intervention, and it established Iris as a viable technology in the fight against stroke.

“Treatment of stroke and other neurovascular diseases represents one of the most significant financial opportunities in healthcare, supported by positive reimbursement dynamics and strong demand from health systems,” Nicholas Drysdale, CFO of XCath, added in the release. “With our continued investor support and disciplined capital deployment, XCath is positioned to build a category-leading platform in endovascular robotics”.
