Three Houston-area companies—Amperon, Hertha Metals and Vaulted Deep—appear on this year’s Global Cleantech 100 list.

The unranked list, generated by market intelligence and advisory firm Cleantech Group, identifies the 100 privately held companies around the world that are most likely to make a significant impact in the cleantech market over the next five to 10 years.

For the 2026 list, Cleantech Group received more than 24,000 Global Cleantech 100 nominations from nearly 60 countries. Cleantech Group scored those companies and narrowed the contenders to 264. An expert panel reviewed those nominees, and the list was whittled down to the 100 winners.

Here’s a rundown of the three Houston-area honorees:

Amperon

Founded in 2018 by Sean Kelly and Abe Stanway, Houston-based Amperon offers an AI-enabled energy forecasting and analytics platform designed to help stabilize electric grids. Amperon received undisclosed amounts of venture capital from National Grid Partners and Tokyo Gas Co. Ltd. last year and announced a recent investment from Samsung Ventures earlier this month.

Hertha Metals

Founded in 2022 by Laureen Meroueh, Conroe-based Hertha Metals provides a single-step process for producing sustainable steel. Last year, the company emerged from stealth mode and raised more than $17 million in venture capital.

Vaulted Deep

Vaulted Deep’s technology injects excess organic waste underground to remove carbon dioxide from the atmosphere. Julia Reichelstein and Omar Abou-Sayed founded the Houston-based company in 2023. Last year, the startup raised $32.3 million in venture capital. Also in 2025, Vaulted Deep signed a 12-year deal with software giant Microsoft to remove up to 4.9 million metric tons of carbon dioxide from the environment.

Vaulted Deep also made the list last year, along with Houston-based Syzygy Plasmonics and Fervo Energy. Fervo was also named the 2025 North American Company of the Year by Cleantech Group.

report card

Three Houston companies claimed spots on LexisNexis's 10 Most Innovative Startups in Texas report, with two working in the geothermal energy space.

Sage Geosystems claimed the No. 3 spot on the list, and Fervo Energy followed closely behind at No. 5. Fintech unicorn HighRadius rounded out the list of Houston companies at No. 8.

LexisNexis Intellectual Property Solutions compiled the report. It was based on each company's Patent Asset Index, a proprietary metric from LexisNexis that identifies the strength and value of each company’s patent assets based on factors such as patent quality, geographic scope and size of the portfolio.

Houston tied with Austin, each with three companies represented on the list. Caris Life Sciences, a biotechnology company based in Dallas, claimed the top spot with a Patent Asset Index more than 5 times that of its next competitor, Apptronik, an Austin-based AI-powered humanoid robotics company.

“Texas has always been fertile ground for bold entrepreneurs, and these innovative startups carry that tradition forward with strong businesses based on outstanding patent assets,” Marco Richter, senior director of IP analytics and strategy for LexisNexis Intellectual Property Solutions, said in a release. “These companies have proven their innovation by creating the most valuable patent portfolios in a state that’s known for game-changing inventions and cutting-edge technologies.We are pleased to recognize Texas’ most innovative startups for turning their ideas into patented innovations and look forward to watching them scale, disrupt, and thrive on the foundation they’ve laid today.”

This year's list reflects a range in location and industry. Here's the full list of LexisNexis' 10 Most Innovative Startups in Texas, ranked by patent portfolios.

  1. Caris (Dallas)
  2. Apptronik (Austin)
  3. Sage Geosystems (Houston)
  4. HiddenLayer (Austin)

  9. LTK (Dallas)
  10. Eagle Eye Networks (Austin)

Sage Geosystems has partnered on major geothermal projects with the United States Department of Defense's Defense Innovation Unit, the U.S. Air Force and Meta Platforms. Sage's 3-megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, was expected to be completed by the end of last year.

Fervo Energy fully contracted its flagship 500 MW geothermal development, Cape Station, this spring. Cape Station is currently one of the world’s largest enhanced geothermal systems (EGS) developments, and the station will begin to deliver electricity to the grid in 2026. The company was recently named North American Company of the Year by research and consulting firm Cleantech Group and came in at No. 6 on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025. It's now considered a unicorn, meaning its valuation as a private company has surpassed $1 billion.

Meanwhile, HighRadius announced earlier this year that it plans to release a fully autonomous finance platform for the "office of the CFO" by 2027. The company reached unicorn status in 2020.

Investment banking firm launches cleantech group, names Houston-based co-leader

new hire

A Houston investment banker has been tapped as co-leader of a new team at investment bank Moelis & Co. that will mine the energy sector for cleantech deals.

Publicly traded Moelis said September 7 that it hired Arash Nazhad as Houston-based managing director and co-head of its newly formed clean energy technology group. Nazhad joins Moelis from financial services giant Citigroup, where he was managing director of its clean energy investment team. He worked at Citigroup for nine years.

During his tenure at Citigroup and, before that, Norwegian energy company Equinor (which operates a Houston office), Nazhad helped carry out more than $50 billion in M&A advisory activities and helped raise over $40 billion in capital for clients. He’s been involved in the rollout of more than 20 IPOs.

“Moelis is very well-positioned to help clients navigate the far-reaching implications of the energy transition that is underway,” Nazhad tells EnergyCapitalHTX. “Houston is a major player in the cleantech ecosystem, and I’m thrilled to join Moelis and leverage the breadth of the firm’s capital market solutions, advisory services, and global connectivity to support clients in this space.”

Nazhad will run the new Moelis group alongside Rick Polhemus, the investment bank’s San Francisco-based managing director. Polhemus, formerly an executive at investment bank Morgan Stanley, joined Moelis last October.

Jeff Raich, co-founder and co-president of Moelis, says the backgrounds of Nazhad and Polhemus make them “uniquely positioned to lead our efforts and expand opportunities for clients in this rapidly changing environment.”

“The energy transition that is underway demands integrated advisory services, access to capital, and strategic long-term planning,” adds Navid Mahmoodzadegan, co-founder and co-president of Moelis.

“Achieving net-zero emissions will require a significant increase in spending,” Mahmoodzadegan adds, “and our dedicated clean energy efforts better position us to be a seamless partner to our strategic, financial sponsor, and venture capital clients as we leverage our dynamic advisory practice and global connectivity.”

Nazhad and his colleagues will be searching for cleantech deals in a supercharged sector.

The International Energy Agency says global investment in cleantech is on track to hit $1.7 trillion this year. An impressive share of that money is being pumped into cleantech startups. Globally, VC funding in the cleantech sector soared from $1.9 billion in 2019 to $12.3 billion in 2022, according to management consulting firm Oliver Wyman.

Nazhad’s M&A experience should prove particularly beneficial for Moelis’ new cleantech arm.

A recent report from management consulting firm West Monroe indicates cleantech M&A “is picking up speed.” The report is based on the firm’s survey of 200 corporate and private equity executives.

“The overarching trend is that cleantech is no longer the stuff of speculation, but a viable sector benefiting from a confluence of tailwinds, including high energy demand, the need for secure supplies that complement fossil fuels, and more ambitious policymaking efforts targeting decarbonization,” the report says.

Energy AI startup chooses Houston for first U.S. office after $20M raise

welcome to houston

London-based AI firm Applied Computing has announced a $20 million Series A round and a new office in Houston.

The new Bayou City office is Applied Computing’s first in the United States and part of its North American expansion. The company is known for its Orbital AI platform, which is tailored for energy operations.

The funding round was led by Houston-based KBR Inc., with participation from San Francisco-based Databricks Ventures. KBR’s investment was first announced in March.

KBR and Applied Computing have also entered into a multi-year agreement to deliver exclusive AI products for the energy sector. KBR already has integrated Orbital into its INSITE 3.0 platform for energy projects, and is also using the product for ammonia production.

Applied Computing’s Orbital platform combines physics-grounded intelligence with models across chemical engineering, time-series forecasting and language, according to the company. The system analyzes sensor readings and can recognize a facility’s equipment constraints and operator activity. The platform can also allow technicians to run simulations of how a change to a facility could affect the rest of its operations.

According to TechCrunch, Applied Computing will use the $20 million to further explore projects and deployments with the energy sector, hire engineering and research positions, and continue to expand internationally, potentially into the Middle East.

The company is also working on deals with a major U.S. stream operator, TechCrunch reports. And Applied Computing shared on LinkedIn that it plans to announce its first partnership with a major European oil company in the coming weeks.

“Yesterday we showed Orbital live in deployments at our demo day at the Energy Institute in London,” Callum Adamson, CEO and co-founder of Applied Computing, posted on LinkedIn on July 16. “Today, we're announcing the capital to scale it globally as well as the launch of our new offices in Houston and Bangalore. In the weeks following, there will be more announcements on our progress, partnerships and deployments.”

The company opened its Bangalore offices in December.

Automakers enter the energy space with vehicles offering backup power

Power Boost

Winter Storm Uri, the multiday freeze that slammed Texas in February 2021 and pummeled the state's power grid, has been on Kenneth Kovar's mind ever since. Though the resident of New Braunfels didn't lose power at the time, he wasn't able to run his septic tank — it is independent from local systems. He had to fill his toilets with water from his backyard pool.

So when Kovar, 64, bought a Ford F-150 last fall, his hope was to be better prepared for any new crisis.

“I was interested in trying to find some sort of power backup situation,” he said.

Now, Kovar has a setup from Ford that allows drivers of certain F-150 models to plug their vehicle directly into their electric meter to power parts of their home during an outage.

It is the latest example of automakers broadly adapting their electrification technologies to the home energy business, especially as demand on the grid increases and sales of electric vehicles slow. Car companies are looking to leverage their multibillion dollar EV investments to tap into a promising market in vehicle, home and grid technology, both for backup power and for supporting electrical grid resiliency.

“They’re trying to look for other businesses that they might sell into,” said Parth Vaishnav, assistant professor of sustainable systems at the University of Michigan.

Ford's latest connects F-150 drivers to their meter

Drivers of the F-150 PowerBoost hybrid and F-150 Lightning electric pickup trucks can now plug in a one-foot long adapter to a 240-volt outlet onboard. That adapter — which Ford made with company Global Power Products — makes the vehicle compatible to plug into a longer, separate cable. That cable connects to a transfer switch installed directly on one's electric meter.

Through the adapter and cable series, homeowners can connect their vehicle essentially right to their home’s breaker box. The homeowner simply turns on and off which breaker switches they want for which devices they want powered.

“The way we think about it, especially for customers who already have a compatible vehicle is, you already own the power source, it’s in your driveway,” said Amanda Roraff, Ford's grid and energy services business acceleration lead.

The Lightning might provide power for two to three days, depending on what home devices are being used, and the PowerBoost Hybrid, up to five days on a single tank of gas.

The automaker says its solution is a less expensive way to supply backup power. Conventional, diesel-powered portable generators and full-home standby setups require expensive installation, costing several thousands of dollars. This solution, which also requires professional installation at the meter, starts around $1,100.

The setup only applies to about 200,000 vehicles so far, and it is also exclusively for outages. Ford also offers its Home Integration System for bidirectionality, sending power both from the vehicle to the home and from the home to the vehicle, while also being able to feed the grid.

Other automakers are boosting their energy solutions

Over 630,000 U.S. vehicles already have this functionality, estimates say, and automakers are rapidly expanding their available options with the goal of full vehicle-to-grid support in the long run.

South Korean auto brand Kia and Wallbox, an EV charging company, have teamed up so that drivers of eligible compatible vehicles can have home power backup during outages or during periods of high demand, to cut their utility use. They can send power back to the grid.

Tesla’s technology is similar — allowing drivers of equipped vehicles to connect to their home using additional Tesla hardware. The Cybertruck provides full vehicle-to-home capability, where other Tesla models can only connect to and power specific devices or appliances.

General Motors is also in the energy space.

A recent partnership with WeaveGrid, for instance, allows homeowners who drive certain GM EVs — and have the automaker’s home system and a proper grid interconnection — to enroll in some grid reliability utility programs. Once an outage is detected, GM’s vehicle-to-home tech has the capability to disconnect one's home from the grid and start supplying power from their GM EV.

“If you can imagine the future as we go forward, it's having the ability — now that we have this single platform — that allows our customer to experience our system,” said Wade Sheffer, vice president of GM energy, “but also can have the full control of the energy.”

The capability is an important lifeline amid EV sales slowdown

Not only is this business critical amid growing grid demand and increasing power outages, experts say automakers need to pivot with the EV market less active under current U.S. federal policy. Pure EV sales in the U.S. year-over-year are down 23.8%, according to a July Cox Automotive report on the first half of 2026. This demonstrates what an asset that EV and hybrid ownership can be.

The tech is not without challenges.

On the industry side, these systems have to undergo third-party testing to ensure they meet safety standards, and the vehicle and the charger need to be programmed to communicate. It also requires the approval of the utility where the capability is being used. It could take years to get an interconnect agreement.

On the customer side, homeowners need to understand their vehicles' abilities and how to self-manage their system. It also just brings another generator of power into the home mix.

Still, experts see opportunity, especially with interest in EV sales high outside of the U.S.

“We already know during an outage, its impact, providing electricity to the home,” said Scott Samuelsen, engineering professor emeritus at the University of California, Irvine. “This is going to become very, very popular.”

Rice, UH join major quantum, nuclear energy initiatives

energy impact

Rice University and the University of Houston will be playing a part in the future of energy in Texas and beyond, as Rice has joined the U.S. Department of Energy Quantum Science Center and UH has been added to the Texas Nuclear Alliance.

Rice’s role with the DOE Quantum Science Center will expand the university’s work in helping to develop “fault-tolerant quantum computers capable of solving scientific problems,” according to Rice. Tirthak Patel, an assistant professor of computer science, will develop and evaluate quantum error-correction decoding methods on high-performance computing platforms. Patel’s team will receive $900,000 over 5 years from a DOE-funded center at Oak Ridge National Laboratory.

The Quantum Science Center was established in 2020 under the National Quantum Initiative Act, and brings together national laboratories, universities and industry partners like IBM, AMD, IQM, Quantinuum and Riverlane, and others to advance quantum information science. The Quantum Science Center is one of the DOE’s five National Quantum Information Science Research Centers, and has planned funding of $125 million over 5 years.

“Reliable error correction is one of the biggest challenges in making quantum computing useful for accelerating scientific discovery,” Patel said in a news release. “Our work is focused on developing methods that can scale to future systems and support practical scientific applications.”

Meanwhile, as power demand continues to rise in Texas and North America, the Texas Nuclear Alliance brings industry, academic, and government leaders together to advance nuclear technologies to meet growing energy demands, support economic efforts, bolster domestic manufacturing, and protect overall energy security.

UH brings expertise to the Texas Nuclear Alliance from UH Energy, the Texas Center for Superconductivity at UH (TcSUH), and the Advanced Manufacturing Institute (AMI). UH says that 11 of its 16 colleges will contribute research to the alliance.

“Texas and the University of Houston have long led the nation in energy innovation and research,” Ramanan Krishnamoorti, vice president of energy and innovation, said in a news release. “As demand for reliable, affordable and secure energy continues to grow, advanced nuclear technologies will become increasingly important. The University of Houston is uniquely positioned to contribute through world-class research and deep industry partnerships that help transform breakthrough discoveries into real-world solutions. We look forward to working with the Texas Nuclear Alliance to accelerate technologies that will shape the future of the energy industry.”

Projects from both Rice and UH were selected this week to participate in the DOE's Genesis Mission. Read more here.
