Chevron warned Monday that its pending $53 billion acquisition of Hess may be in jeopardy because it will require the approval of Exxon Mobil and a Chinese national oil company, which both hold rights to development of an oil field off the coast of the South American nation Guyana.
The disclosure in a filing with the Securities and Exchange Commission raised investor qualms, depressing shares of both Chevron and Hess. Chevron's stock price fell 3% Tuesday morning before rebounding; Hess stock lost 4% of its value but bounced back slightly.
Chevron's acquisition of Hess would add this major oil field in Guyana as well as shale properties in the Bakken Formation in North Dakota. Guyana is a country of 791,000 people that is poised to become the world’s fourth-largest offshore oil producer, placing it ahead of Qatar, the United States, Mexico and Norway. It has become a major producer in recent years, with oil giants including Exxon Mobil, China’s CNOOC, and Hess squared off in a heated competition for highly lucrative oil fields in northern South America.
Chevron said it's been engaged in discussion with Exxon and CNOOC, aka China National Offshore Oil Co. Both companies hold rights of first refusal for decisions regarding the oil field in question, known as the Stabroek Block. Exxon Mobil operates the Stabroek Block and holds 45% interest. Hess holds 30% interest, and CNOOC holds the remaining 25% interest. Production capacity at the field is expected to reach more than 1.2 million barrels per day by the end of 2027, Exxon said in November.
If those discussions and subsequent arbitration fail to set aside those first refusal rights, Chevron said, “the merger would not close.”

Last month, oil companies offered $382 million for drilling rights in the Gulf of Mexico on Wednesday after courts rejected the Biden administration's plans to scale back the sale to protect an endangered whale species.
The auction was the last of several offshore oil and gas lease sales mandated under the 2022 climate law. It comes as President Joe Biden’s Democratic administration tries to navigate between energy companies seeking greater oil and gas production and environmental activists who want to stop new drilling to help combat climate change.
Companies including Houston-based Chevron and Hess and BP, each with a Houston presence, offered bids on more than 300 parcels covering 2,700 square miles (7,000 square kilometers), according to the U.S. Department of Interior's Bureau of Ocean Energy Management.
The dollar amount of the successful bids marked a sharp increase from the previous sale in March 2023, when the Interior Department awarded leases covering about 2,500 square miles (6,500 square kilometers) for $250 million.
The next sale will be conducted in 2025, to the frustration of energy companies and Republicans who say the administration is hampering U.S. oil production.
Wednesday's online auction was originally scheduled for September but got delayed by a court battle after the administration reduced the area available for leases from 73 million acres (30 million hectares) to 67 million acres (27 million hectares) as part of a plan to protect the endangered Rice’s whale.
Chevron, Shell Offshore, the American Petroleum Institute and the state of Louisiana sued to reverse the cut in acreage and block the inclusion of the whale-protecting measures in the lease sale provisions.
A federal judge in southwest Louisiana ordered the sale to go on without the whale protections, which also included regulations governing vessel speed and personnel. Environmental groups appealed, but the New Orleans-based 5th Circuit Court of Appeals last month rejected their arguments against the sale and threw out the plans to scale it back.
The lease sale was required under a compromise with Democratic Sen. Joe Manchin of West Virginia, a supporter of the oil and gas industry who cast the deciding vote in favor of the landmark climate law. The measure was approved with only Democratic votes in Congress. Under the terms negotiated by Manchin, the government must offer at least 60 million acres of offshore oil and gas leases in any one-year period before it can offer offshore wind leases that are part of its strategy to fight climate change.
Only a small portion of parcels that are offered for sale typically receive bids, in areas where companies want to expand their existing drilling activities or where they foresee future development potential.
Environmental groups criticized the five-year plan as a “missed opportunity” to stop the expansion of oil and gas drilling in the Gulf of Mexico and address climate change.
“New oil and gas operations (in the Gulf) will only bring more health risks to Gulf Coast communities and slow our transition to a clean-energy economy,'' said Earthjustice attorney Brettny Hardy.
The industry, meanwhile, said more sales are needed — and sooner.
“In our forward-thinking industry, securing new lease blocks is vital for exploring and developing resources crucial to the U.S. economy,'' said National Ocean Industries Association President Erik Milito. “The Gulf of Mexico is a prime economic engine and investment area, and this (lease sale) was the last chance for companies to secure leases in the near term.''
Holly Hopkins, API vice president of upstream policy, called Wednesday's sale "a "positive step after multiple delays,'' and noted that it generated the highest dollar value for bids in nearly a decade.
The results demonstrate that the oil and gas industry “is working to meet growing demand and investing in the nation’s long-term energy security,'' Hopkins said. “Just as today’s record U.S. production was supported by investment and policy decisions made years ago, new leasing opportunities are critical for maintaining American energy leadership for decades to come.''
The administration's clean-energy ambitions have been hampered by recent project cancellations including two large wind projects shelved last month off the New Jersey coast and the earlier cancellation of three projects that would have sent power to New England.
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.

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.”
