Houston-based startup Altillion has secured $5 million in seed funding to accelerate the commercialization of its proprietary IRIS and ALIX technologies, which convert oilfield-produced water into valuable minerals.
San Francisco-based EIC Rose Rock and Houston-based Flathead Forge led the round. Altillion says the funding will go toward pilot facilities and commercial deployments as the company looks to scale in the U.S.
“Altillion’s efficient and scalable technologies are needed more than ever to reshape critical mineral recovery and facilitate beneficial use of oilfield brines,” Jay Keener, Altillion’s CEO and co-founder, said in a news release. “We’re uniquely positioned to provide a stable, domestic supply of the critical minerals needed for electronics, batteries, healthcare and national defense technologies. This investment from EIC Rose Rock and Flathead Forge enables us to strategically accelerate this impact and is very timely given the current geopolitical dynamics.”
Altillion's IRIS and ALIX platforms extract minerals like iodine, lithium and copper from oilfield-produced water, geothermal brines and salars. This process allows companies to unlock new sources of revenue while also boosting the domestic critical minerals supply chain. The company announced earlier this summer that it will launch a feasibility project in the Permian Basin and aims to develop a path to commercial-scale implementation in the field.
“We are excited to partner with Altillion to scale and deploy these world-class technologies to access the vast wealth hidden in wastewater,” David Clouse, Managing Director of EIC Rose Rock, added in the release. “With Altillion, we’re expanding our ability to empower the energy industry to domestically source the critical minerals America needs for a robust economy and supply chain.”
Altillion was founded by Keener and COO Scott Buckwald in 2023. Keener previously founded KDH Trading, where Buckwald also serves as COO, according to his LinkedIn page.
Houston-based Helix Earth Technologies has closed a $12 million Seed 2 funding round to scale manufacturing of its energy-efficient commercial HVAC add-on technology.
Veriten, a Houston-based energy investment firm, led the round. Rua Ventures, Carnrite Ventures, Skywriter LLC and Textbook Ventures also participated.
Helix Earth—which was founded based on NASA technology, spun out of Rice University and has been incubated at Greentown Labs—is developing high-efficiency retrofit dehumidification systems that aim to reduce the energy consumption of commercial HVAC units. The company reports that its technology can lead to "healthier indoor air, lower energy bills, reduced building maintenance, and more comfortable spaces for building owners and occupants."
"Building owners are dealing with rising energy costs, uncontrolled humidity, and aging infrastructure with no viable, cost-effective path forward. We are in the field today solving these problems for commercial customers, and this capital puts us on an aggressive path to scale,” Rawand Rasheed, Helix Earth co-founder and CEO, said in a news release.
“The strength of this round reinforces our team's conviction that we can transform innovation-starved sectors with transformational solutions that deliver order-of-magnitude improvements to owners and operators, for both their bottom line and the environment,” Rasheed added.
Maynard Holt, Veriten’s founder and CEO, said that the investment firm is tripling its investment in Helix Earth.
"The team has built breakthrough technology with real applicability across multiple industries,” Holt said in the release. “Their first product will have an immediate and measurable impact on our energy system, and they are already pursuing adjacent innovations to help heavy industries operate more efficiently and with less waste. This is a well-rounded team with a proven track record of strong execution and disciplined capital management.”
Houston-based climatech startup Aquanta Vision achieved key milestones in 2025 for its enhanced methane-detection app and has its focus set on future funding.
Aquanta Vision’s funding went toward commercializing its NETxTEN app, which automates leak detection to improve accuracy, speed and safety. The company estimates that methane leaks cost the U.S. energy industry billions of dollars each year, with 60 percent of leaks going undetected. Additionally, methane leaks account for around 10 percent of natural gas's contribution to climate change, according to MIT’s climate portal.
Throughout the months-long ASCEND program, Aquanta Vision moved from the final stages of testing into full commercial deployment of NETxTEN. The app can instantly identify leaks via its physics-based algorithms and raw video output of optical gas imaging cameras. It does not require companies to purchase new hardware, requires no human intervention and is universally compatible with all optical gas imaging (OGI) cameras. During over 12,000 test runs, 100 percent of leaks were detected by NETxTEN’s system, according to the company.
The app is geared toward end-users in the oil and gas industry who use OGI cameras to perform regular leak detection inspections and emissions monitoring. Aquanta Vision is in the process of acquiring new clients for the app and plans to scale commercialization between now and 2028, Babur Ozden, the company’s founder and CEO, tells Energy Capital.
“In the next 16 months, (our goal is to) gain a number of key customers as major accounts and OEM partners as distribution channels, establish benefits and stickiness of our product and generate growing, recurring revenues for ourselves and our partners,” he says.
The company also received an investment for an undisclosed amount from Marathon Petroleum Corp. late last year. The funding complemented follow-on investments from Ecosphere Ventures and Odyssey Energy Advisors.
Ozden says the funds will go toward the extension of its runway through the end of 2026. It will also help Aquanta Vision grow its team.
Ozden and Marcus Martinez, a product systems engineer, founded Aquanta Vision in 2023 and have been running it as a two-person operation. The company brought on four interns last year, but is looking to add more staff.
Ozden says the company also plans to raise a seed round in 2027 “to catapult us to a rapid growth phase in 2028-29.”

Solaris Assets has completed its acquisition of the majority of Sunnova Energy International’s residential solar assets. Houston-based Sunnova filed for Chapter 11 bankruptcy this summer after piling up billions of dollars in debt.
Meanwhile, Sunnova founder and former CEO John Berger has launched a Houston-based home energy services startup, Otovo USA, which just received more than $4 million in seed funding.
Solaris now owns Sunnova’s residential solar services platform and its solar generation and storage portfolio, along with leases, loans and power purchase agreements. Sunnova’s operations are being shifted to SunStrong Management, an Austin-based asset manager for the renewable energy sector.
“By bringing together SunStrong’s asset management expertise with Sunnova’s nationally scaled customer base, we are creating a stronger, more capable leader in the solar industry,” Brendon Merkley, CEO of SunStrong, said in a news release. “Our priority is to maintain the highest levels of service for customers as we expand our footprint as a premier solar asset servicer.”
In June, Sunnova sold its new-home business to homebuilder Lennar for $15.2 million and sold certain assets to investment firm Atlas SP Partners for $15 million.
As of December, Sunnova’s debt totaled nearly $10.7 billion, Reuters reported. Sunnova faced numerous challenges in its quest to survive, including higher interest rates, the reduction of solar incentives in California, and a shakeup in federal subsidies for renewable energy.
Sunnova filed for Chapter 11 bankruptcy in June. A month later, a bankruptcy judge approved the court-supervised sale of Sunnova. Solaris’ acquisition of Sunnova closed Sept. 3.
As SunStrong absorbs the bulk of Sunnova’s assets, Berger — who quit in March as Sunnova’s CEO — has formed a new business. He’s now the founder and CEO of Otovo USA, a partner of European residential power company Otovo.
Otovo USA offers solar power systems, solar batteries, standby generators, EV chargers, electric-load managers, and other power generation and management systems. Otovo’s AI-supported offerings are now available in Texas; the company plans to expand nationwide.
Otovo USA raised its seed funding from the EIC Rose Rock Venture Fund, which invests in energy startups.
“Otovo USA is here to help the millions of Americans with home energy services that are fed up with the complexities of warranties, juggling multiple vendors, and long repair times,” Berger said. The startup, he added, “is bringing customers what they really need: reliable power and a single partner accountable for keeping it up and running. It’s your power, backed by ours.”

Houston-based Collide, a provider of generative artificial intelligence for the energy sector, has raised $5 million in seed funding led by Houston’s Mercury Fund.
Other investors in the seed round include Bryan Sheffield, founder of Austin-based Parsley Energy, which was acquired by Dallas-based Pioneer Natural Resources in 2021; Billy Quinn, founder and managing partner of Dallas-based private equity firm Pearl Energy Investments; and David Albin, co-founder and former managing partner of Dallas-based private equity firm NGP Capital Partners.
“(Collide) co-founders Collin McLelland and Chuck Yates bring a unique understanding of the oil and gas industry,” Blair Garrou, managing partner at Mercury, said in a news release. “Their backgrounds, combined with Collide’s proprietary knowledge base, create a significant and strategic moat for the platform.”
Collide, founded in 2022, says the funding will enable the company to accelerate the development of its GenAI platform. GenAI creates digital content such as images, videos, text, and music.
Originally launched by Houston media organization Digital Wildcatters as “a professional network and digital community for technical discussions and knowledge sharing,” the company says it will now shift its focus to rolling out its enterprise-level, AI-enabled solution.
Collide explains that its platform gathers and synthesizes data from trusted sources to deliver industry insights for oil and gas professionals. Unlike platforms such as OpenAI, Perplexity, and Microsoft Copilot, Collide’s platform “uniquely accesses a comprehensive, industry-specific knowledge base, including technical papers, internal processes, and a curated Q&A database tailored to energy professionals,” the company said.
Collide says its approximately 6,000 platform users span 122 countries.

A Houston startup with clean tech originating out of NASA has secured millions in funding.
Helix Earth Technologies closed an oversubscribed $5.6 million seed funding led by Houston-based research and investment firm Veriten. Anthropocene Ventures, Semilla Capital, and others including individual investors also participated in the round.
“This investment will empower the Helix Earth team to accelerate the development and deployment of our first groundbreaking hardware technology designed to disrupt a significant portion of the commercial air conditioning market, an industry that is ready for innovation,” Rawand Rasheed, Helix Earth co-founder and CEO, says in a news release.
Helix Earth was founded based on NASA technology co-invented by Rasheed and spun out of Rice University and has been incubated at Greentown Labs in Houston since 2022. Currently being piloted, the technology is estimated to save up to half of the net energy used in commercial air conditioning, reducing both emissions and costs for operators.
“The enthusiastic response from investors reinforces our team’s confidence in our ability to transform innovation-starved sectors such as commercial air conditioning with an easy-to-install-and-maintain solution that benefits distributors, mechanical contractors, and most of all, building owners, with a positive benefit to the environment,” Rasheed says.
Prior to its raise, the company received grant funding from the National Science Foundation and the United States Department of Energy.
“We couldn’t be more excited to partner with the Helix Earth team," Maynard Holt, Veriten’s founder and CEO, adds. "We were so impressed with their unique combination of a technology with broad applicability across multiple industries, a product that will have an immediate and measurable impact on our energy system, and a fantastic and well-rounded team.”
Helix Earth, per the release, reports that is also looking to provide solutions for commercial humidity control and carbon capture.
Fervo Energy’s flagship project in Utah just generated its first geothermal power.
The electricity is now flowing to the power grid from one of Cape Station’s three generation units, Houston-based Fervo said in a news release. This represents an early but important milestone for the project, as the unit isn’t scheduled to deliver contracted power until Oct. 1.
The achievement, coming four months after Fervo’s roughly $2.2 billion IPO, demonstrates the viability of enhanced geothermal systems (EGS).
“This is a gamechanger for the geothermal industry. It establishes EGS as the defining new power generation technology of our time, and we believe it shows that the commercial and technical maturity of EGS is ready to meet the urgent need for reliable, clean power,” Tim Latimer, co-founder and CEO of Fervo, said in the release.
The plant’s two other units are scheduled to launch commercial operations on Jan. 1.
The three units make up the project’s 99-megawatt first phase. The next phase, which will add 400 megawatts of capacity, is under construction. The second phase is set to go online in 2028.
Altogether, Cape Station will provide more than 4 gigawatts of capacity, with 900 megawatts already spoken for. The 900 megawatts of contracted electricity would be enough to power nearly 1 million U.S. homes per year.
“Cape Station works because we treated the subsurface like an engineering challenge,” Jack Norbeck, co-founder and chief technology officer of Fervo, added in the release. “Years of drilling, completion design, subsurface modeling, and flow testing led to this moment, and this is the validation that matters most.”
Enhanced geothermal continuously draws on heat that’s deep underground, producing electricity around the clock regardless of weather or time of day. That makes it one of the only carbon-free resources capable of constant power delivery, which is critical for data centers and AI infrastructure.
While hundreds of thousands descend on New York for Climate Week, Houston offered a different proposition: come where the work is being built. And last week Houston proved that it’s solving for more energy and fewer emissions; reliability and affordability; speed and durability. We are solving for the “&.”
That equation sharpened last week. On Sept. 14, the Environmental Protection Agency announced it had repealed most 2024 federal carbon-pollution standards for power plants and proposed rescinding remaining greenhouse-gas requirements. Policy matters, but it can pivot. The need to build does not.
HECW is a proving ground, not another conference stop. As I wrote in the Houston Chronicle, Mayor Sylvester Turner planted the seed by insisting we bring people together across the city and industry to drive Houston’s energy future. He knew false choices have no place here: oil and gas and clean technology; prosperity and stewardship; industry and lower emissions.
ECW joined the Climate Week Network this year, connecting Houston to a growing community of more than 500,000 people across 22-plus cities. We now have a seat at the global table—and a responsibility to use it well, building with other cities and the wider clean-energy-solutions world rather than merely talking at them.
The capital is already moving. Since 2017, Houston Energy Transition Initiative member companies have invested more than $95 billion in low-carbon infrastructure, technologies, and research and development. This is where the transition is financed, engineered, tested and operated. But the work requires more than capital. It requires capital allocators who understand the difference between a promising idea and a project that can scale, hire and endure.
Last week was Houston’s show and tell. At ARTECHOUSE, The &Bassador Reception & Awards brought art, technology, culture, philanthropy and energy together. Then the week went beyond downtown.
Sugar Land Town Square became the launchpad for the Metro Innovation Tour & Market: a place for an ecosystem conversation about smart cities, clean energy, equitable access and next-generation mobility before participants boarded three tour routes across greater Houston. It was also the starting point for the Bay City South Innovation Tour to Erthos Project Bravo in Matagorda County, where small groups saw Earth Mount solar modules being installed in real time. The conversation did not end at a panel. It went to the project site.

Approximately 100 startups from around the world pitched at Rice Alliance, Greentown Labs and Halliburton Labs events. At Astros Night at Daikin Park, builders, backers, and believers traded conference rooms for the diamond, creating an experience, not just another event. That is how this work becomes civic fabric.
Activation also means making the energy story felt, not merely explained. AY Young brought the Battery Tour for live performances. It was a reminder that the “Power of &” is not confined to a boardroom or a laboratory. Art and technology, culture and commerce, a new generation and established industry can share the same stage—and help more people see themselves in the work ahead.
Perhaps no activation made the “Power of &” more immediate and real than the Houston, We Have Solutions open mic night. At Creatopia’s Innovation Studio, people took the mic—or simply listened—to share what they were building, the problem they could not stop thinking about, and the connection they hoped to make. It put founders, artists, community builders, researchers and future-makers in one room. That is collaboration in real time: different kinds of expertise meeting before anyone knows exactly what the solution will be.
FOX26 helped carry that story beyond the rooms we convened, hosting Erthos COO Jessica Knight, Mars Materials co-founder Aaron Fitzgerald, and investors Taylor Chapman and Juliana Garaizar to discuss building and backing the future in Houston. Our region should be proud—not as self-congratulation, but because the world is beginning to experience energy and climate solutions firsthand.
This was also a week to give back. Allies in Energy awarded $27,500 to nine organizations advancing energy and climate literacy, civil dialogue, workforce pathways and community action. NRG Energy’s Brighter Communities provided a founding gift to expand the week and fund local grants. It took partners, hosts, sponsors, volunteers, funders and community organizations. That is the “Power of &”: collaboration that leaves a stronger community behind.
The “Power of &” cannot stop at Houston’s city limits. Louisiana’s participation—through its support of the Digital Delta Symposium & Expo—made clear that Houston’s builder ecosystem is regional by necessity. Gulf Coast infrastructure, supply chains, talent, and industrial decisions do not recognize state lines. Neither should our collaboration. If we are serious about building more energy with fewer emissions, we must align capital, resources and opportunity across the entire Gulf Coast.
That same commitment to practical collaboration means listening, learning and adjusting. A builder’s mindset does not protect a plan simply because it came first; it improves the conditions for the work to succeed. That is why Houston Energy and Climate Week will move to April 4–10, 2027—better weather, more time and space for connection, and a stronger city-wide experience for the people building what comes next.
But the real test begins now. Can we keep widening the circle? Can we continue to turn research into projects, pilots into infrastructure, capital into good jobs and climate ambition into results that families and communities can see? Can we make every new solution stronger by bringing in the people who must finance it, build it, operate it, live beside it and benefit from it?
That is the work ahead. Turner understood that Houston does not move forward by asking who wins the argument. It moves forward by asking who is ready to solve the problem. His legacy—and the promise of the “&”—is an invitation to choose collaboration over division, action over performance and possibility over false choices.
The future does not need another city to talk about it. It needs Houston to keep building it. And it will only be built if we keep choosing the "&."
Responding to public outcry, Gov. Greg Abbott has stepped up his campaign against data centers by temporarily halting approval of environmental permits for data center projects.
This and previous moves by Abbott essentially amount to a temporary freeze on the development of new data centers in Texas. His actions come at a time when Texas’ stature as a data center hub has been soaring.
On Monday, Abbott directed the Texas Commission on Environmental Quality to stop issuing permits for data center developments until the Electric Reliability Council of Texas (ERCOT) and Public Utility Commission of Texas complete their review of projects seeking power grid connections.
With regulatory reviews underway and environmental permitting now frozen, state regulators currently cannot approve or deny requests from data center developers, Abbott said.
In a letter to the environmental quality commission’s executive director, Kelly Keel, Abbott said this directive is “consistent with my whole-of-government approach to ensure Texans’ natural resources and way of life are protected.”
Abbott previously ordered the Texas Water Development Board to require data centers to meet reporting requirements for water use. He also told the board to impose penalties for failure to comply with those requirements and to collaborate with ERCOT on its review.
Abbott launched his crackdown on data centers in August by ordering the Public Utility Commission and ERCOT to review data center projects in Texas. The audits will examine all data centers in the queue for interconnections before any more projects can move forward. Interconnections enable data centers to share power, data and computing resources.
In calling for those audits, Abbott cited concerns over data centers’ use of water and electricity, and the centers’ effect on infrastructure expenses and consumers’ utility rates.
“Simply put, Texans must come first,” the governor said.
During next year’s legislation session, Abbott will push for the elimination of state financial incentives for data center projects.
Ed Hirs, an energy fellow at the University of Houston, told Reuters that Abbott was backtracking on “his earlier pronouncements about data centers leading to lower electricity prices.”
Abbott’s actions come amid growing public backlash over data centers. A recent University of Houston survey found that nearly 63 percent of Houston-area residents opposed construction of a data center within a mile of their home.
