Workplace safety has always been reactive. Incidents happen, reports are filed, lessons are learned — sometimes too late. But what if safety wasn’t about reacting to accidents, but preventing them altogether?

In this episode of the Energy Tech Startups Podcast, Stephen Ojji, founder and CEO of VisionTech, challenges how high-hazard industries approach safety. His vision? AI-driven incident detection that doesn’t just monitor the workplace —i t actively prevents injuries, ensures compliance, and builds a stronger safety culture.

From Oil and Gas Safety to AI Innovation

Stephen’s journey into energy tech isn’t what you’d expect. Starting as a safety engineer in Nigeria’s oil and gas sector, his early career was focused on ensuring compliance, training teams, and reducing workplace risks. But he quickly realized a flaw in the system — many incidents weren’t being reported at all.

"Workers don’t always report hazards, and not because they don’t care," he explains. "Sometimes it’s fear of consequences. Sometimes it’s just human nature — we’re focused on getting the job done. But ignoring small risks leads to big accidents."

That’s where VisionTech’s AI-powered safety monitoring system comes in. Instead of relying on human reporting, VisionTech integrates with existing workplace cameras, using computer vision technology and AI to detect:

  • Spills, fire hazards, and safety violations in real-time
  • Workers at risk of injury due to incorrect lifting techniques or missing PPE
  • Trends in safety culture, helping companies address recurring risks

"Think of it like having an extra set of eyes that never blinks," Stephen says. "Not to police workers, but to protect them."

AI and Safety: Moving Beyond Compliance to Prevention

Unlike traditional workplace monitoring, VisionTech’s AI safety system doesn’t track individuals — it tracks behaviors. The system uses ghosting technology, ensuring that workers’ identities remain anonymous while hazards are flagged instantly.

This shifts the focus from penalizing mistakes to empowering safer work environments.

"Companies say they care about safety, but what does that really mean?" Stephen challenges. "If safety is the priority, why not use every tool available to protect workers before an accident happens?"

And here’s the kicker: VisionTech doesn’t just detect risks. It helps companies act on them.

Instead of logging safety incidents in spreadsheets that go unread, the system transforms safety data into actionable insights — identifying patterns, trends, and areas for improvement that help companies make real, lasting changes.

Why Now? The Urgency for Smarter Safety Solutions

With OSHA regulations tightening and ESG commitments pushing for stronger worker protections, industrial companies are under growing pressure to do more than just meet compliance standards.

At the same time, AI and machine learning have advanced rapidly, making AI-powered safety monitoring more affordable, scalable, and accurate than ever before.

"If we had tried to build this 10 years ago, it wouldn’t have worked," Stephen admits. "The technology wasn’t ready. The market wasn’t ready. But today? It’s the right time, and the right tool for a problem that’s been ignored for too long."

What’s Next for VisionTech?

Currently in the MVP stage, VisionTech is preparing for pilot programs with oil and gas companies to prove its impact in real-world environments. The plan? Scale beyond oil and gas into manufacturing, construction, and any industry where safety matters.

But for Stephen, this isn’t just about launching another safety product — it’s about changing how companies think about protecting their workers.

"Safety isn’t just a compliance box to check," he says. "It’s about people. If companies really believe that ‘our employees are our greatest asset,’ then investing in their safety should be the easiest decision they ever make."

This is a conversation you don’t want to miss.

What if the future of clean energy wasn’t just about invention, but execution? For Sujatha Kumar, CEO of Dsider, success in clean tech hinges on more than groundbreaking technology—it’s about empowering founders with the tools to make their innovations viable, scalable, and economically sound.

Through Dsider’s techno-economic analysis (TEA) platform, Kumar is helping startups bridge the critical gap between vision and execution, ensuring they can navigate complex markets with confidence.

In a recent episode of the Energy Tech Startups Podcast, Kumar shared her insights on the growing importance of TEA in the hard tech space. While clean energy innovation promises transformative solutions, the challenge lies in proving both technical feasibility and economic sustainability. Kumar argues that many early-stage founders, especially in fields like carbon capture, microgrids, and renewable energy, lack the necessary financial tools to assess market fit and long-term profitability—a gap Dsider aims to fill.

What Makes Dsider Unique?

Dsider offers more than just financial modeling—it creates actionable insights, tailored to the demands of the clean energy sector. At its core, the platform integrates TEA with operational planning, equipping founders with the ability to run scenario analyses, optimize pricing strategies, and anticipate market challenges. “It’s not just about building a product—it’s about understanding how to make that product thrive in a dynamic, ever-evolving market,” Kumar explained.

In industries where data is limited and stakes are high, startups often struggle to translate early pilots into scalable solutions. Kumar emphasized how Dsider’s approach helps founders forecast regulatory shifts, project downtime risks, and identify key economic drivers—turning complex calculations into a clear strategic roadmap. This foresight enables startups to align with customer expectations and investor requirements from the outset, a step that is often overlooked in early development stages.

Why TEA is Critical for Founders

“Clean tech innovation is hard,” Kumar emphasized, “because there is no historical data to guide decisions.” Startups often operate in unfamiliar territory, where understanding market fit and pricing models is essential. Through TEA, founders can build a financial narrative, simulate real-world conditions, and show investors or customers how their solutions will perform.

Jason, an experienced founder, echoed this sentiment, reflecting on his own mistakes:

"I wish I’d done a TEA earlier—during my first pilot, we didn’t budget for enough support, and it cost us a key customer."

The takeaway? Even at the pilot stage, TEA is invaluable. As Kumar noted, failing early pilots can prevent startups from scaling—making upfront analysis essential for success.

Beyond Technology: Bridging Gaps Between Founders, Investors, and Customers

Kumar highlighted the need to align founders, investors, and customers through a shared understanding of value. TEA enables this by allowing founders to communicate in the same language as their stakeholders—from efficiency gains to regulatory compliance. Dsider's platform provides tools for scenario modeling, allowing startups to optimize for both technology performance and economic outcomes.

One challenge, she noted, is that many founders are scientists without financial backgrounds. “Our goal is to simplify that complexity, so founders can focus on their technology while we take care of the analysis,” Kumar explained. Dsider helps startups anticipate questions from investors, simulate risks, and optimize business models from the start.

A New Way to Sell: Using TEA as a Business Development Tool

Kumar described how TEA can be more than a financial tool—it can become a business development asset. Founders can use Dsider to create customized reports for potential customers, demonstrating the specific value their technology brings. With interactive models and scenario analysis, startups can quickly respond to customer needs and build trust through transparency.

Future Growth

Looking ahead, Dsider aims to scale its operations and expand its impact by continuing to support early-stage founders with affordable, high-impact tools. With growing regulatory support for clean tech and an increasing demand for sustainable solutions, Dsider is positioned to become a key player in the energy tech startup ecosystem.

By bridging the gap between innovation and economics, Dsider is helping founders navigate complex challenges and build businesses that are both profitable and impactful—setting a strong foundation for future growth in the climate tech space.

Houston podcasters aim to showcase promising local energy tech startups

broadcasting innovation

Houston has a bit of a perception problem, according to Jason Ethier, a long-time energy tech innovator and new podcast host.

"Houston isn't viewed as a cool place to build a company if you don't know how good it is to be here," he says on the Houston Innovators Podcast.

Ethier, who serves as senior director of membership at Greentown Labs, set out to fix that when he launched the EnergyTech Startups podcast last fall with co-host Lara Cottingham, the vice president of strategy, policy, and climate impact at Greentown Labs. To date, the show has introduced listeners to over 20 energy founders and is continuing to do so on a biweekly basis.

"As an entrepreneur, sometimes you feel a gap in the market in your bones and you just have to do something about it," Ethier explains on the origin of the show.

With his background in the Northeast, Ethier has seen first hand how Houstonians are just different — they tackle tough challenges and are heads-down focused on these innovations.

"Houston has a lot going for it as a place to build a business, and we're not going to do it the Silicon Valley. We do things the Houston way — we build new technologies, we build big projects," Ethier says. "The funny thing about Houstonians I find is that they are very understated with what they achieve and accomplish like it's no big deal. But it is a big deal."

That's where Ethier and the podcast can help shine a spotlight on the unique innovation these startup founders are in the process of commercializing.

"The premise of EnergyTech Startups is that we're building an energy ecosystem here, and energy and climate are two sides of the same coin," he says. "People working on these energy technologies made the choice to come to Houston — they made the choice not to go to Silicon Valley or Boston."

The goal is twofold — give these startups the platform to tell their story and showcase Houston as the hub for energy innovation.

"How do we tell this Houston story so that whenever folks look at the map and say, 'where do I want to build my business?' they look at Houston and see it as a place they should end up," he says.

3 Houston energy companies rank among most innovative startups in Texas

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)
  5. Fervo Energy (Houston)
  6. Plus One Robotics (San Antonio)
  7. Diligent Robotics (Austin)
  8. HighRadius (Houston)
  9. LTK (Dallas)

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.

Tech entrepreneur turned climate investor is on a mission to monetize carbon removal

now streaming

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:

  1. The people in power don’t actually have this figured out, and
  2. 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.

Rice scientist receives $2 million award for research on 'new type of fuel'

winner, winner

Rice University chemistry professor László Kürti was named as a recipient of the 2025 Ross M. Brown Investigator Award from the California Institute of Technology’s Brown Institute for Basic Sciences.

Kürti is one of eight mid-career faculty members to receive up to $2 million over five years for their research in the physical sciences.

“I’m greatly honored,” Kürti said in a news release. “We will learn a tremendous amount in the next five years and gain a much clearer understanding of the challenges ahead.”

Kürti was selected for the research he’s been developing for six years on a molecule called tetrahedral N4, which studies show can release large amounts of energy on demand. The molecule can also decompose directly into nitrogen gas without producing carbon dioxide or water vapor. Kürti believes N4 can be used as a "new type of fuel for vehicles."

“Eventually, N4 and other stable, neutral polynitrogen cages could be used to power rockets, helping us reach the moon or Mars faster and with heavier payloads,” he added in this release.

The Brown Investigator Awards were founded by entrepreneur and Caltech alumnus Ross M. Brown and established by the Brown Science Foundation in 2020. The organization has recognized 21 scientists over the last five years.

“Midcareer faculty are at a time in their careers when they are poised and prepared to make profound contributions to their fields,” Brown said in the news release. “My continuing hope is that the resources provided by the Brown Investigator Awards will allow them to pursue riskier innovative ideas that extend beyond their existing research efforts and align with new or developing passions, especially during this time of funding uncertainty.”
