In a move that environmentalists called a betrayal, the Biden administration has approved the construction of a deepwater oil export terminal off the Texas coast that would be the largest of its kind in the United States.

The Sea Port Oil Terminal being developed off Freeport, Texas, will be able to load two supertankers at once, with an export capacity of 2 million barrels of crude oil per day. The $1.8 billion project by Houston-based Enterprise Products Partners received a deepwater port license from the Department of Transportation's Maritime Administration this week, the final step in a five-year federal review.

Environmentalists denounced the license approval, saying it contradicted President Joe Biden's climate agenda and would lead to “disastrous” planet-warming greenhouse gas emissions, equivalent to nearly 90 coal-fired power plants. The action could jeopardize Biden's support from environmental allies and young voters already disenchanted by the Democratic administration's approval last year of the massive Willow oil project in Alaska.

“Nothing about this project is in alignment with President Biden’s climate and environmental justice goals,'' said Kelsey Crane, senior policy advocate at Earthworks, an environmental group that has long opposed the export terminal.

“The communities that will be impacted by (the oil terminal) have once again been ignored and will be forced to live with the threat of more oil spills, explosions and pollution,'' Crane said. "The best way to protect the public and the climate from the harms of oil is to keep it in the ground.”

In a statement after the license was approved, the Maritime Administration said the project meets a number of congressionally mandated requirements, including extensive environmental reviews and a federal determination that the port's operation is in the national interest.

“While the Biden-Harris administration is accelerating America’s transition to a clean energy future, action is also being taken to manage the transition in the near term,'' said the agency, which is nicknamed MARAD.

The administration's multiyear review included consultation with at least 20 federal, state and local agencies, MARAD said. The agency ultimately determined that the project would have no significant effect on the production or consumption of U.S. crude oil.

“Although the (greenhouse gas) emissions associated with the upstream production and downstream end use of the crude oil to be exported from the project may represent a significant amount of GHG emissions, these emissions largely already occur as part of the U.S. crude oil supply chain,'' the agency said in an email to The Associated Press. “Therefore, the project itself is likely to have minimal effect on the current GHG emissions associated with the overall U.S. crude oil supply chain.''

Environmental groups scoffed at that claim.

“The Biden administration must stop flip-flopping on fossil fuels,'' said Cassidy DiPaola of Fossil Free Media, a nonprofit group that opposes the use of fossil fuels such as oil, coal and natural gas.

“Approving the Sea Port Oil Terminal after pausing LNG exports is not just bad news for our climate, it’s incoherent politics,'' DiPaola said. Biden “can’t claim to be a climate leader one day and then turn around and grant a massive handout to the oil industry the next. It’s time for President Biden to listen to the overwhelming majority of voters who want to see a shift away from fossil fuels, not a doubling down on dirty and deadly energy projects.''

DiPaola was referring to the administration's January announcement that it is delaying consideration of new natural gas export terminals in the United States, even as gas shipments to Europe and Asia have soared since Russia invaded Ukraine.

The decision, announced at the start of the 2024 presidential election year, aligned the Democratic president with environmentalists who fear the huge increase in exports of liquefied natural gas, or LNG, is locking in potentially catastrophic planet-warming emissions even as Biden has pledged to cut climate pollution in half by 2030.

Industry groups and Republicans have condemned the pause, saying LNG exports stabilize global energy markets, support thousands of American jobs and reduce global greenhouse emissions by transitioning countries away from coal, a far dirtier fossil fuel.

Enterprise CEO Jim Teague hailed the oil project's approval. The terminal will provide “a more environmentally friendly, safe, efficient and cost-effective way to deliver crude oil to global markets,'' he said in a statement.

The project will include two pipelines to carry crude from shore to the deepwater port, reducing the need for ship-to-ship transfers of oil. The terminal is expected to begin operations by 2027.

Since the project was first submitted for federal review in 2019, “Enterprise has worked diligently with various federal, state and local authorities, and participated in multiple public meetings that have allowed individuals and stakeholder groups to learn about the project and provide their comments,'' including some studies that have been translated into Spanish and Vietnamese, the company said in a statement. More than half of Freeport's 10,600 residents are Hispanic, according to the U.S. Census Bureau.

Sen. Ted Cruz, R-Texas, hailed the license approval as “a major victory for Texas’s energy industry" and said the Biden administration had delayed the Sea Port terminal and other projects for years.

“After tireless work by my office and many others to secure this deepwater port license, I’m thrilled that we’re helping bring more jobs to Texas and greater energy security to America and our allies,'' Cruz said in a statement. “That this victory was delayed by years of needless bureaucratic dithering shows why we need broader permitting reform in this country.''

The oil export facility, one of several license applications under federal review, is located 30 miles offshore of Brazoria County, Texas, in the Gulf of Mexico.

The license approval followed a ruling by the Fifth Circuit Court of Appeals last week dismissing claims by environmental groups that federal agencies had failed to uphold federal environmental laws in their review of the project.

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.”
