Ken Nguyen oversees the implementation of new technologies at bp, which has its United States headquarters in Houston, and that includes software and hardtech, from cybersecurity to the digitization of the industry, which is an integral part of bp's energy transition plan.
"For bp, we do feel like as we transition as an international oil and gas company into an integrated energy company and we lean into the energy transition, the adoption of new technology is a critical part of making that viable for the planet and for the company," he says on the Houston Innovators Podcast.
According to Nguyen, principal technical program manager at bp, the company has invested its resources into exploring energy transition technologies like electric vehicle charging — including opening a fast-charging station at its Houston office — and renewable energy, including a solar farm about 10 miles northeast of Corpus Christi.
Another technology bp is keen on is digital twin technology, which can be crucial for enhancing safety for bp personnel and reducing emissions.
Nguyen says digital twin technology "allows us to be able to design and mirror scenarios with real-time variables, such as weather, off-take demands, and volatility."
"Houston has always been known as the Space City, and we're also known as the Energy Capital of the World, but there hasn't always been collaboration," Nguyen says. "The challenges that NASA is facing is very similar to the challenges that the oil industry faces — we operate in very harsh environments, safety is the most critical aspect of our operation, and now the economic business model for NASA has changed."
Nguyen explains that while both bp and NASA are navigating similar challenges and changes within their industry, they are going about it in different ways. That's where the opportunity to collaborate comes in.
The partnership, which is still new and not fully fleshed out, will look at collaborative innovation into a few focus areas to start out with, including hydrogen storage and development, AI and general intelligence, robotics, and remote operations
"Houston continues to excel — in energy production and in space exploration — but by coming together," Nguyen says, "and for us to be able to tap into (NASA's) knowledge is tremendous. And we, within oil and gas, have a unique set of skills to blend into that with the hopes being that the city becomes this incubator for technology. The potential is there."

The energy transition has momentum, according to Wogbe Ofori. But there's still a ways to go.
Ofori, the founder and chief strategist of WRX Companies, is an adviser to Nauticus Robotics and strategist to Intuitive Machines and Jacobs, he's also served as a mentor across the local innovation community. He's narrowed in on hardtech and has has gotten a front-row seat to observing what's happening in Houston amid the energy transition, as he explains on this week's episode of the Houston Innovators Podcast.
Listen to the episode and read an excerpt below.
EnergyCapital: Looking back on some of the recent trends of the energy transition, what have you observed?
Wogbe Ofori: The energy transition has been something that — through the last hype cycle that started in the second half of 2020 and lasted until the first quarter of 2022 — was part of that momentum along with Web3. Now, the energy transition is continued as Web3 has fallen off a cliff and now been replaced by AI, but the energy transition is continued. Where I think moving into the next major stage where now it’s time for them to actually be proven out. And these things are hard and take time to be proven out and these technologies to mature. Then for the products and services that are derived from them, to really find the right place within the market and the right use cases. The idea that there is some sort of silver bullet — whether it be hydrogen or something else — that's going to solve the problem for all use cases is completely unrealistic. The issue is that a lot of folks especially the big energy players — the O&G majors here — they know that.
EC: So, what does this next stage look like?
WO: Now we're moving into what I think is a really interesting period where it's going to be, “well do we really have the legs for this race?” Because we sprinted, and everybody got really excited. Now you starting to hear, “well you know some investors are a little worried that cleantech 2.0 might suffer some of the same fate as cleantech 1.0.” How do we avoid that? Will investors have the patience to continue to make investments into energy transition plays for the longer term, because we’re going to need that to make these transitions. It's not going to happen overnight.
EC: Where does Houston come in on all this?
WO: Well the other big question that’s being asked around is, “Can Houston actually lead this?” It's difficult for an incumbent to disrupt itself. We’ve been positioning ourselves as moving from the energy capital of the world to the energy transition capital. I'm all for it, and I'm 100 percent behind it. Now we are just at the place where we're really going to start to see the difference between those who were caught up in the excitement of the energy transition, and those who really have the faith to see this thing through. The ones who do have the faith to see this through are going to create some fantastic companies that are going to create real value and that will materially change the way we live. But it’s going to take time and be hard.

The robots are coming. Although the rise of Chat GPT has frightened plenty of professionals, we’re not on the precipice of the singularity just yet. And some of Houston’s coolest robots are contained in above-ground tanks, simply doing jobs that are too expensive and difficult for humans. The mechanical helpers in question come courtesy of Square Robot.
Square Robot co-founder and chief technology officer Jerome Vaganay started the company in 2016 in Boston. The company opened its Houston office in August of 2019.
“A lot of our partners and client base is out of here,” says director of operations, Matt Crist.
Karishma Prasad, director of technical operations, who joined the team in Houston earlier this year, adds “It’s a great centralized place for us. Houston is a great hub both nationally and internationally. There is so much energy transition innovation happening here.”
Square Robot is indeed a robotics company, but it trades in a very specific type of robot. The SR-1 is an innovative tank inspector.
“Since the ‘60s there’s been a traditional way of going into a tank. People would go inside and clean it with a variety of products," Crist explains. "Once it was clean, they would come in and inspect it repair it and that could take months.”
In fact, it could often cause a 15 or 16-week outage, he says.
Square Robot’s brainstorm was to take the human element out of the process. In other words, robots can do the job more safely, efficiently and quickly than a human ever could by collecting 18,000 data points per square foot, while allowing the product — most often diesel — to stay in the tank.
Square Robot saves those vast weeks of time, but perhaps even more importantly, says Prasad, “We’re avoiding emissions being released into the atmosphere.”
With its key location in Houston, Square Robot has worked with most of the major names in the energy world, including ExxonMobil, Chevron, BP, and Crist’s former employer, Phillips 66.
The latest robot is the SR-3, which is currently being tested in Houston. Curious webwatchers can see its progress on Square Robot’s website. Unlike the flagship SR-1, the new robot boasts a side launcher that allows it to be completely immersed in a tank before being launched.
But perhaps the most exciting thing about Square Robot’s 15-human Houston office is its test tank. There, potential partners can see exactly what the company’s ingenious creation can do. Square Robot will participate in ILTA, the International Operating Conference & Trade Show, which takes place from May 21-24. On the 24th, the company will host an open house from noon to 3 p.m. to allow potential users to see the SR-3 in action in the 42-foot-long test tank.
Square Robot will complete its hundredth tank inspection in May. It is also growing beyond the oil and gas world to include work with the power industry and was recently selected as a finalist in the Incubatenergy Lab Start Up program. This is one robot that we will happily allow to take over formerly all-too-human responsibilities.

Houston maintained its No. 3 status this year among U.S. metro areas with the most Fortune 500 headquarters. Fortune magazine tallied 26 Fortune 500 headquarters in the Houston area, behind only the New York City area (62) and the Chicago area (30).
Last year, 23 Houston-area companies landed on the Fortune 500 list. Fortune bases the list on revenue that a public or private company earns during its 2024 budget year.
On the Fortune 500 list for 2025, Spring-based ExxonMobil remained the highest-ranked company based in the Houston area as well as in Texas, sitting at No. 8 nationally. That’s down one spot from its No. 7 perch on the 2024 list. During its 2024 budget year, ExxonMobil reported revenue of $349.6 billion, up from $344.6 billion the previous year.
Here are the rankings and 2024 revenue for the 25 other Houston-area companies that made this year’s Fortune 500:
Nationally, the top five Fortune 500 companies are:
Walmart
Amazon
UnitedHealth Group
Apple
CVS Health
“The Fortune 500 is a literal roadmap to the rise and fall of markets, a reliable playbook of the world's most important regions, services, and products, and an indispensable roster of those companies' dynamic leaders,” Anastasia Nyrkovskaya, CEO of Fortune Media, said in a news release.
Among the states, Texas ranks second for the number of Fortune 500 headquarters (54), preceded by California (58) and followed by New York (53).
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.
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.
The climate conversation is evolving — fast. It’s no longer just about emissions targets and net-zero commitments. It’s about capital, infrastructure, and execution at industrial scale.
That’s exactly where Yao Huang operates. A seasoned tech entrepreneur turned climate investor, Yao brings sharp clarity to one of the biggest challenges in climate innovation: how do we fund and scale technologies that remove carbon without relying on goodwill or government subsidies?
In this episode of the Energy Tech Startups Podcast, Yao sits down with hosts Jason Ethier and Nada Ahmed for a wide-ranging conversation that redefines how we think about decarbonization. From algae-based photobioreactors that capture CO₂ at the smokestack, to financing models that mirror real estate and infrastructure—not venture capital—Yao lays out a case for why the climate fight will be won or lost on spreadsheets, not slogans.
Her message is as bold as it is practical: this isn’t about saving the planet for the sake of it. It’s about building profitable, resilient systems that scale. And Houston, with its industrial base and project finance expertise, is exactly the place to do it.
The 40-Gigaton Challenge—and a Pandemic Pivot
Yao’s entry into climate wasn’t part of a long-term plan. It was sparked by a quiet moment during the pandemic—and a book.
Reading How to Avoid a Climate Disaster by Bill Gates, she came to two uncomfortable realizations:
The people in power don’t actually have this figured out, and
She would be alive to suffer the consequences.
That insight jolted her out of the traditional tech world and into climate action. She studied at Stanford, surrounded herself with mentors, and began diving into early-stage climate deals. But she quickly realized that most of the solutions she was seeing were still years away from commercialization.
So she narrowed her focus: no R&D moonshots, no science experiments—just deployable solutions that could scale now.
Carbon Optimum: Where Algae Meets Infrastructure
That’s how she found Carbon Optimum, a company using algae photobioreactors to remove CO₂ directly from industrial emissions. Their approach is both elegant and economic:
Install algae reactors next to major emitters like coal and cement plants.
Feed the algae with flue gas, allowing it to absorb CO₂ in a controlled system.
Harvest the algae and convert it into valuable commodities like bio-oils, fertilizer, and food ingredients.
It’s a nature-based solution, enhanced by engineering. One acre of tanks can capture emissions and generate profit—without subsidies.
“This is one of the few solutions I’ve seen that can scale profitably and quickly,” Yao says. “And we’re not inventing anything new—we’re just doing it better.”
The Real Problem? It’s Capital, Not Carbon
As an investor, Yao is blunt: most climate startups are misaligned with the capital markets.
They’re following a tech startup playbook—built for SaaS, not steel. But building climate infrastructure requires a completely different approach: project finance, blended capital, debt structures, carbon credit integration, and regulatory incentives.
“Climate tech is more like real estate or healthcare than software,” Yao explains. “You don’t raise six rounds of venture. You build a stack—grants, equity, debt, tax credits—and you structure your project like infrastructure.”
It’s not just theory. It’s exactly how Carbon Optimum is expanding—through partnerships, offtake agreements, and real-world deployments. And it’s why she believes many climate startups fail: they don’t speak the language of finance.
Houston’s Role in the Climate Capital Stack
For Yao, Houston isn’t just a backdrop—it’s a strategic asset.
The city’s deep bench of project finance professionals, commodity traders, lawyers, and infrastructure veterans makes it uniquely positioned to lead the deployment phase of climate solutions.
“We’ve been calling it the wrong thing,” she says. “This isn’t just about climate—it’s an energy transition. And Houston knows how to build energy infrastructure at scale.”
Still, she notes, the ecosystem needs to evolve. Less education, more execution. Fewer workshops, more closers.
“Houston could be the epicenter of this movement—if we activate the right people and get the right projects over the line.”
From Carbon Capture to Circular Economies
The potential applications of Carbon Optimum’s algae platform go beyond carbon capture. Because the output—algae biomass—can be converted into:
Renewable oil
High-efficiency fertilizers (critical in today’s geopolitically fragile supply chains)
Food ingredients rich in protein and nutrients
Even biochar, a highly stable form of carbon sequestration
It’s scalable, modular, and location-agnostic. In island nations, Yao notes, these systems can offer energy independence by turning waste CO₂ into local energy and fertilizer—without needing to import fuels or food.
“It’s not just emissions reduction. It’s economic sovereignty through circular systems.”
Doing, Not Just Talking
One of Yao’s key takeaways for founders? Don’t waste time. Climate startups don’t have the luxury of trial-and-error cycles stretched over years.
“Founders need to get real about what it takes to scale: talent, capital, storytelling, partnerships. If you’re not ready to do that, maybe you should be a CSO, not a CEO.”
She also points out that founders don’t need to hire everyone—they need to tap the right networks. And in cities like Houston, those networks exist—if you know how to motivate them.
“It takes a different kind of leadership. You’re not just raising money—you’re moving people.”
Why This Episode Matters
This conversation is for anyone who’s serious about scaling real solutions to the climate crisis. Whether you’re a founder navigating capital markets, an investor seeking return and impact, or a policymaker designing the frameworks — Yao Huang offers a grounded, urgent, and actionable perspective.
It’s not about hope. It’s about execution.
