Eight major players in Houston’s energy industry rank among the world’s top 20 energy companies for corporate startup activity.
The inaugural Corporate Startup Activity Index 2025, published by StartupBlink, ranks global corporations by industry. The eight Houston-area employers fall into the index’s energy and environment category.
Researchers from StartupBlink, an innovation research platform, scored more than 370 companies based on three factors: corporate involvement in startup activity, startup success and ecosystem integration.
The eight Houston-area energy employers that landed in the energy and environment category’s top 20 are:
No. 3 BP. Score: 13.547. U.S. headquarters in Houston.
No. 5 Saudi Aramco. Score: 7.405. Americas headquarters in Houston.
No. 7 Eni. Score: 6.255. Headquarters of Eni U.S. Operating Co. in Houston.
No. 8 Shell. Score: 6.217. U.S. headquarters in Houston.
No. 11 Occidental Petroleum. Score: 5.347. Global headquarters in Houston.
No. 15 Engie. Score: 3.352. North American headquarters in Houston.
No. 17 Repsol. Score: 2.980. U.S. headquarters for oil and gas operations in The Woodlands.
No. 19 Chevron. Score: 2.017. Global headquarters in Houston.
“Building a startup is hard, and navigating corporate innovation can be just as complex. This ranking is a step toward making the connection between startups and corporations more transparent, enabling startups and corporations to collaborate more effectively for mutual success,” said Eli David Rokah, CEO of StartupBlink.
Salesforce topped the global index with a score of 380.090, followed by Intel, Google, Qualcomm, and Comcast.

A new analysis positions the Energy Capital of the World as an economic dynamo, albeit a flawed one.
The recently released Oxford Economics Global Cities Index, which assesses the strengths and weaknesses of the world’s 1,000 largest cities, puts Houston at No. 25.
Houston ranks well for economics (No. 15) and human capital (No. 18), but ranks poorly for governance (No. 184), environment (No. 271), and quality of life (No. 298).
New York City appears at No. 1 on the index, followed by London; San Jose, California; Tokyo; and Paris. Dallas lands at No. 18 and Austin at No. 39.
In its Global Cities Index report, Oxford Economics says Houston’s status as “an international and vertically integrated hub for the oil and gas sector makes it an economic powerhouse. Most aspects of the industry — downstream, midstream, and upstream — are managed from here, including the major fuel refining and petrochemicals sectors.” Continue reading.
In Texas last month, coal use dropped and solar energy soared, according to a new report. Photo via Pexels
For the first time in Texas, according to a recent report, solar energy generation surpassed the output by coal.
The report — from the Institute For Energy Economics and Financial Analysis — sourced the Energy Information Administration’s hourly grid monitor for March 2024. This shift in a predominantly oil and gas dominated history of Texas energy output, was due to solar power’s 3.26 million megawatt-hours to Electric Reliability Council of Texas (ERCOT) grid, compared to coal’s 2.96 million MWh.
In addition, coal’s market share fell below 10 percent to 9 percent for the first time ever, to just over 9 percent. The increase in solar energy pushed solar’s share of ERCOT generation to more than 10 percent for the month, which was also a first. Continue reading.

Turns out — Texas might not be as green as you thought.
A new report from WalletHub looked at 25 key metrics — from green buildings per capita to energy consumption from renewable resources — to evaluate the current health of states' environment and residents’ environmental-friendliness. Texas ranked No. 38, meaning it was the thirteenth least green state, only scoring 50.40 points out of 100.
“It’s important for every American to do their part to support greener living and protect our environment. However, it’s much easier being green in some states than others," writes Cassandra Happe, a WalletHub Analyst, in the report. "For example, if a state doesn’t have a great infrastructure for alternative-fuel vehicles, it becomes much harder for residents to adopt that technology. Living in a green state is also very beneficial for the health of you and your family, as you benefit from better air, soil and water quality.” Continue reading.

In a new report that ranked states with the most electric vehicle chargers, Texas falls behind other similarly-sized states
The SmartAsset study looked at the closest EV charging stations equivalent to a trip to the gas station — factoring in each state's population. California, with its 14,500 charging stations, has five times the EV charging stations as New York (3,327), Florida (2,913) and Texas (2,472). While California ranked No. 1 on the list, Texas found itself at No. 41.
The report used EV charger and station data for each state from the U.S. Department of Energy for 2022 and 2021. Population data is for 2022 and comes from the U.S. Census Bureau 1-Year American Community Survey. Cities were also ranked by the number of fast chargers per capita. In 2022, Texas had 1,386 fast DC chargers, 2,472 EV charging stations, and a fast charger growth year over year 53.5 percent. Continue reading.
A new report ranks Texas as one of the least cycling-friendly states in the U.S., citing poor infrastructure, limited bike routes, and low safety measures, highlighting the need for improved sustainable transportation. Photo by Photo Mizuno K/Pexels
In what will come as no surprise to cyclists around Houston, the state of Texas is not a good place for bicycle riding. According to a new report of the "Most Cycling-Friendly States in the U.S.," Texas comes in at No. 47 — meaning that only three other states are worse.
The report, from Philadelphia personal injury law firm KaplunMarx, examines all 50 states based on six metrics: Air quality index, the number of cyclist deaths per one million residents, bike routes per square mile, local government actions supporting cycling, federal funding for cycling projects, and bicycle laws.
Texas musters a mere 31 points out of 100 for its "cycling friendly score."
The most cycling friendly state in the U.S.: Minnesota, which earned 84 points to claim the title.
According to the report's findings, there have been 15 local government actions per capita in Texas that integrate pedestrians and cyclists in transportation projects. Texas' has a 41 air quality index value, and there are approximately 1.2 bike routes per 1,000 square miles in the state.
On cyclist deaths, Texas does a little better, with three cyclist deaths per one million residents in Texas — about nine percent lower than the national average.
According to KaplunMarx founding partner Ted Kaplun, there is an average of 857 cyclist fatalities in the U.S. every year. He adds that every measure or community effort to improve cyclist-friendliness is beneficial for all Americans.
"It's crucial for all states to continually assess and enhance their cycling provisions, learning from both high-ranking peers and their own experiences," he says.
Top-ranking Minnesota has only one cyclist death per one million state residents. It also has about 27.2 bike routes per 1,000 square miles.
After Minnesota, the remaining top five best states for cyclists are Massachusetts (No. 2), Rhode Island (No. 3), Washington (No. 4), and Iowa (No. 5).
At the bottom of the list are Nevada (No. 48), Arizona (No. 49), and Utah (No. 50) — all of which performed far worse than Texas to be declared the three least cycling-friendly states.
The entire country still has areas for improvement when it comes to creating a safer environment for cyclists, regardless of where each state landed on the list, according to Kaplun.
"With over 53 million Americans riding bicycles regularly, the importance of cycling-friendly infrastructure and safety measures cannot be overstated," said Kaplun in the report. "This isn't just about rankings – it's about enhancing the quality of life, promoting sustainable transportation, and most crucially, saving lives."
The report ranked each state on both its home and auto efficiency. Texas came in No. 32 for home energy efficiency, which factored in the National Weather Service's annual degree days.
For auto efficiency, Texas came in at No. 38, but ranked No. 43 for vehicle-fuel efficiency specifically and No. 20 for transportation efficiency.
"We divided the annual vehicle miles driven by gallons of gasoline consumed to determine vehicle-fuel efficiency and measured annual vehicle miles driven per capita to determine transportation efficiency," according to WalletHub, which used data from the U.S. Census Bureau, National Climatic Data Center, U.S. Energy Information Administration, and U.S. Department of Transportation - Federal Highway Administration.
Texas receives mixed reviews when it comes to energy reports from WalletHub. A June report found that Texas ranked as the fourth cheapest state for energy, and in April the state was found to be the thirteenth least green state.
Zooming in on Houston, the reports don't look any better. Earlier this month, the Bayou City was ranked the third worst metro when it comes to the country's greenest cities.

Bad news, Houston. The Bayou City is the third worst metro when it comes to the country's greenest cities.
According to WalletHub's recently released
Greenest Cities in America report, Houston is No. 98 out of 100 of the largest cities that were ranked in the study, which was based on information from the U.S. Census Bureau, U.S. Environmental Protection Agency, The Trust for Public Land, U.S. Department of Energy - The Alternative Fuels Data Center, and more.
“There are plenty of things that individuals can do to adopt a green lifestyle, from recycling to sharing rides to installing solar panels on their homes. However, living in one of the greenest cities can make it even easier to care for the environment, due to sustainable laws and policies, access to locally-grown produce and infrastructure that allows residents to use vehicles less often," says Chip Lupo, WalletHub Analyst. "The greenest cities also are better for your health due to superior air and water quality.”
Houston scored 36.88 points out of 100, and comes in dead last on the environment ranking. Here's how the city performs when it comes to the other metrics:
No. 87 for transportation
No. 52 for energy sources
No. 61 for lifestyle and policy
No. 91 for greenhouse-gas emissions per capita
No. 30 for percent of green space
No. 86 for median air quality index
No. 97 for annual excess fuel consumption
No. 56 for percent of commuters who drive
No. 39 for walk score
No. 33 for farmers markets per capita
The big winners on the report are mostly on the West Coast. Of the top 10, six cities are from California. These are the greenest cities, per the report:
San Diego, California
Washington, D.C.
Honolulu, Hawaii
San Francisco, California
San Jose, California
Seattle, Washington
Oakland, California
Portland, Oregon
Fremont, California
Irvine, California
Texas isn't seen on the list until Austin, which ranked No. 26. The rest of the major Lone Star State major metros include San Antonio at No. 44, Fort Worth at No. 76, and Dallas at No. 81.
While this report is pretty damning, there's not a general consensus that all hope is lost for Houston when it comes to being green. Last year, the city was ranked as having the lowest carbon footprint, based on a report from Park Sleep Fly.
However, WalletHub's report has pretty consistently ranked Houston low on the list. Last year, Houston was slightly higher up at No. 95. In 2022 and 2021, the city claimed the No. 93 spot.
Shocker: Houston made another list of cities with the worst traffic. Courtesy photo
Few things are more frustrating for Houston drivers than sitting in bumper-to-bumper traffic. You're late, you're stuck, and you're wasting time and gas — every single day. It's no surprise that the Bayou City has ranked inside the top 10 in a new list of cities with the worst traffic.
The average Houston driver lost 62 hours to traffic delays in 2023, according to Inrix's latest Global Traffic Scorecard. That's 16 hours more than the time tallied in 2022, and 20 hours more than the national average of 42 hours lost. Ouch!
Trends across the country after the pandemic continue to contribute to congestion. Remote work has led to a longer stretch of high-traffic hours instead of the usual pre-9 am and post-5 pm rush hour surges — and less predictable peaks at that.
"On any given day, everybody might be going into the office and no one is expecting it," David Schrank, a senior research scientist at Texas A&M Transportation Institute, told The Hill in June 2024. "What if next Monday everybody gets called in? Then boom — it's gridlock."
On top of that, truck-related congestion (as anyone driving across Texas knows) has increased with the continued rise of e-commerce and home delivery, with one truck equaling two to three cars on the road.
To see where congestion is the biggest problem nationwide, Stacker ranked the 25 cities in the U.S. with the most time lost per driver due to congestion, according to data from Inrix. Houston lands at No. 8, the worst in Texas. Of course, Houstonians don't need a new survey to tell them just how miserable our traffic is - as our late, beloved columnist Ken Hoffman expressed earlier this year.
Three other cities in Texas have made the top 25-worst list: Dallas is No. 17, Austin is No. 21, and San Antonio rounds out the whole list at No. 25.
Stacker's analysis includes how much delays cost drivers based on median hourly wages in each metro area, per the Bureau of Labor Statistics, and comparisons to pre-COVID-19 pandemic hours lost, measured in 2019. Inrix calculated commute times by looking exclusively at the time it takes to get to and from major employment centers based on anonymized GPS data.
Downtown speed is the speed at which a commuter should expect to travel 1 mile into the city's downtown or central business area during peak morning hours, and the first quarter of 2024 versus the first quarter of 2023 metric is the change in travel times during those two periods.
Veolia, a Boston-based company with major operations in Texas, is purchasing hazardous-waste company Clean Earth from Enviri as part of a $3 billion deal.
Veolia is a private water operator, technology provider and hazardous waste and pollution treatment company that operates a large hazardous waste treatment and incineration facility in Port Arthur. Hazardous waste treatment is a growing sector as the clean energy, semiconductor manufacturing, healthcare and pharmaceutical industries generate high levels of waste that need to be handled safely.
Acquiring Clean Earth’s 82 facilities, which include 19 EPA-permitted sites, will expand Veolia’s reach into 10 new states and will position the company as the second-largest hazardous waste operator in the U.S., according to a news release. The deal is Veolia’s sixth and largest North American acquisition of 2025.
“(The acquisition) allows us to unlock the full value potential of our U.S. hazardous waste activities and to double our size on this critical, fast-growing sector, creating a No. 2 player,” Estelle Brachlianoff, CEO of Veolia, said in a news release. “We reinforce our global capacities in hazardous waste and further increase our international footprint.”
Veolia’s Port Arthur facility specializes in servicing generators with large-volume waste treatment requirements.
The transaction is expected to close mid-2026. Veolia hopes the increased exposure into industries such as retail and healthcare will help to offer a full range of environmental services across the U.S.
“This continued transformation of our portfolio enhances the growth profile and strength of our group, uniquely positioned to tackle the sustained demand for environmental security,” Brachlianoff added in the release.
Houston’s Reliant and San Francisco tech company GoodLeap are teaming up to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant (VPP) network in Texas.
Through the new partnership, eligible Reliant customers can either lease a battery or enter into a power purchase agreement with GoodLeap through its GoodGrid program, which incentivises users by offering monthly performance-based rewards for contributing stored power to the grid. Through the Reliant GoodLeap VPP Battery Program, customers will start earning $40 per month in rewards from GoodLeap.
“These incentives highlight our commitment to making homeowner battery adoption more accessible, effectively offsetting the cost of the battery and making the upgrade a no-cost addition to their homes,” Dan Lotano, COO at GoodLeap, said in a news release.“We’re proud to work with NRG to unlock the next frontier in distributed energy in Texas. This marks an important step in GoodLeap reaching our nationwide goal of 1.5 GW of managed distributed energy over the next five years.”
Other features of the program include power outage plans, with battery reserves set aside for outage events. The plan also intelligently manages the battery without homeowner interaction.
The partnership comes as Reliant’s parent company, NRG, continues to scale its VPP program. Last year, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 in an effort to help households manage and lower their energy costs.
“We started building our VPP with smart thermostats across Texas, and now this partnership with GoodLeap brings home battery storage into our platform,” Mark Parsons, senior vice president and head of Texas energy at NRG, said in a the release. “Each time we add new devices, we’re enabling Texans to unlock new value from their homes, earn rewards and help build a more resilient grid for everyone. This is about giving customers the opportunity to actively participate in the energy transition and receive tangible benefits for themselves and their communities.
Corrosion is not something most people think about, but for Houston's industrial backbone pipelines, refineries, chemical plants, and water infrastructure, it is a silent and costly threat. Replacing damaged steel and overusing chemicals adds hundreds of millions of tons of carbon emissions every year. Despite the scale of the problem, corrosion detection has barely changed in decades.
In a recent episode of the Energy Tech Startups Podcast, Anwar Sadek, founder and CEO of Corrolytics, explained why the traditional approach is not working and how his team is delivering real-time visibility into one of the most overlooked challenges in the energy transition.
From Lab Insight to Industrial Breakthrough
Anwar began as a researcher studying how metals degrade and how microbes accelerate corrosion. He quickly noticed a major gap. Companies could detect the presence of microorganisms, but they could not tell whether those microbes were actually causing corrosion or how quickly the damage was happening. Most tests required shipping samples to a lab and waiting months for results, long after conditions inside the asset had changed.
That gap inspired Corrolytics' breakthrough. The company developed a portable, real-time electrochemical test that measures microbial corrosion activity directly from fluid samples. No invasive probes. No complex lab work. Just the immediate data operators can act on.
“It is like switching from film to digital photography,” Anwar says. “What used to take months now takes a couple of hours.”
Why Corrosion Matters in Houston's Energy Transition
Houston's energy transition is a blend of innovation and practicality. While the world builds new low-carbon systems, the region still depends on existing industrial infrastructure. Keeping those assets safe, efficient, and emission-conscious is essential.
This is where Corrolytics fits in. Every leak prevented, every pipeline protected, and every unnecessary gallon of biocide avoided reduces emissions and improves operational safety. The company is already seeing interest across oil and gas, petrochemicals, water and wastewater treatment, HVAC, industrial cooling, and biofuels. If fluids move through metal, microbial corrosion can occur, and Corrolytics can detect it.
Because microbes evolve quickly, slow testing methods simply cannot keep up. “By the time a company gets lab results, the environment has changed completely,” Anwar explains. “You cannot manage what you cannot measure.”
A Scientist Steps Into the CEO Role
Anwar did not plan to become a CEO. But through the National Science Foundation's ICorps program, he interviewed more than 300 industry stakeholders. Over 95 percent cited microbial corrosion as a major issue with no effective tool to address it. That validation pushed him to transform his research into a product.
Since then, Corrolytics has moved from prototype to real-world pilots in Brazil and Houston, with early partners already using the technology and some preparing to invest. Along the way, Anwar learned to lead teams, speak the language of industry, and guide the company through challenges. “When things go wrong, and they do, it is the CEO's job to steady the team,” he says.
Why Houston
Relocating to Houston accelerated everything. Customers, partners, advisors, and manufacturing talent are all here. For industrial and energy tech startups, Houston offers an ecosystem built for scale.
What's Next
Corrolytics is preparing for broader pilots, commercial partnerships, and team growth as it continues its fundraising efforts. For anyone focused on asset integrity, emissions reduction, or industrial innovation, this is a company to watch.
Energy Tech Startups Podcast is hosted by Jason Ethier and Nada Ahmed. It delves into Houston's pivotal role in the energy transition, spotlighting entrepreneurs and industry leaders shaping a low-carbon future.
