Calling all energy tech startups — you don't want to miss the opportunity to pitch at the inaugural Energy and Climate Startup Week in Houston.

Applications are open now for Rice Alliance for Technology and Entrepreneurship's Energy Tech Venture Forum, which will take place on September 12 as a part of the first Energy and Climate Startup Week in Houston that is taking place September 9 to 13. While ETVF has been hosted by Rice every year for over 20 years, this will be the first time startups will be pitching as a part of the bigger, citywide event.

The event "will showcase energy tech innovations to shift towards a more sustainable, reliable and lower carbon future across interactive panels, inspiring keynotes and over 50 dynamic venture pitches," according to Rice Alliance.

Ninety selected startups will get one-on-one time with the 75 investors who attend the event — each company will have around four to 10 meetings set up for them — and then 40 companies will continue on to pitch to the attendees of the event. Additionally, the Class 4 of the Rice Alliance Clean Energy Accelerator, which was recently announced on EnergyCapital, will also be featured for 10 Demo Day pitches.

Startup founders have until July 12 to apply online.

In addition to the pitches, the September 12 event will feature keynote addresses, panels, and investor-only office hours.

Port Houston receives $25 million grant for Bayport hydrogen project

The Port of Houston Authority (Port Houston) received a $25 million grant from The Department of Transportation and the Federal Highway Administration this month to go toward a hydrogen fueling station for heavy-duty trucks in Bayport, known as Bayport HRS.

The funds will also support a public-private collaboration between the port and industrial gas company Linde Inc. with additional partners GTI Energy, Argonne National Laboratory and Center for Houston’s Future, according to a statement.

“The Houston Ship Channel is the busiest waterway in the nation,” Charlie Jenkins, Port Houston CEO, said in the news release. “As one of the channel’s leading advocates, Port Houston is committed to fostering sustainability, resilience, collaboration, and quality of life for the community and nation we serve.”

Bayport HRS will be an innovative pipeline-based hydrogen refueling station (HRS), which will be able to offer high fueling throughput and be publicly accessible. Linde will design, construct, own and operate the new facility.

“Partnering with Linde, one of the largest hydrogen producers in the world and owner of a major pipeline complex that serves the Houston region, is in line with the Port’s strategy of engaging the Houston Ship Channel industry on projects that benefit the community, promote sustainability, decarbonization, and clean transportation,” Rich Byrnes, Port Houston chief infrastructure officer, said in the news release.

Bayport HRS supports the Port’s Sustainability Action Plan and its net-zero emissions goal by 2050. The project will also align with national strategies for clean hydrogen and transportation decarbonization.

Another goal of the collaboration is to support the U.S. National Blueprint for Transportation Decarbonization, the National Zero-Emission Freight Corridor Strategy, and U.S. National Clean H2 Strategy and Roadmap.

In 2024, Port Houston secured nearly $57M in grant funding in sustainability efforts.

"The Houston/Gulf Coast's regional clean hydrogen economy continues to gain momentum, including with announcements such as this,” Brett Perlman, managing director at the Center for Houston's Future, said in the news release. "We are excited to be part of this important work to build out a clean hydrogen transportation network. This is also another great example of collaboration among business, government and community to get things done."

Innovative Houston clean hydrogen company expands to Brazil

on the move

Houston biotech company Cemvita has expanded into Brazil. The company officially established a new subsidiary in the country under the same name.

According to an announcement made earlier this month, the expansion aims to capitalize on Brazil’s progressive regulatory framework, including Brazil’s Fuel of the Future Law, which was enacted in 2024. The company said the expansion also aims to coincide with the 2025 COP30, the UN’s climate change conference, which will be hosted in Brazil in November.

Cemvita utilizes synthetic biology to transform carbon emissions into valuable bio-based chemicals.

“For decades Brazil has pioneered the bioeconomy, and now the time has come to create the future of the circular bioeconomy,” Moji Karimi, CEO of Cemvita, said in a news release. “Our vision is to combine the innovation Cemvita is known for with Brazil’s expertise and resources to create an ecosystem where waste becomes opportunity and sustainability drives growth. By joining forces with Brazilian partners, Cemvita aims to build on Brazil’s storied history in the bioeconomy while laying the groundwork for a circular and sustainable future.”

The Fuel of the Future Law mandates an increase in the biodiesel content of diesel fuel, starting from 15 percent in March and increasing to 20 percent by 2030. It also requires the adoption of Sustainable Aviation Fuel (SAF) and for domestic flights to reduce greenhouse gas emissions by 1 percent starting in 2027, growing to 10 percent reduction by 2037.

Cemvita agreed to a 20-year contract that specified it would supply up to 50 million gallons of SAF annually to United Airlines in 2023.

"This is all made possible by our innovative technology, which transforms carbon waste into value,” Marcio Da Silva, VP of Innovation, said in a news release. “Unlike traditional methods, it requires neither a large land footprint nor clean freshwater, ensuring minimal environmental impact. At the same time, it produces high-value green chemicals—such as sustainable oils and biofuels—without competing with the critical resources needed for food production."

In 2024, Cemvita became capable of generating 500 barrels per day of sustainable oil from carbon waste at its first commercial plant. As a result, Cemvita quadrupled output at its Houston plant. The company had originally planned to reach this milestone in 2029.

Capitalism and climate: How financial shifts will shape our behavior

guest column

I never imagined I would see Los Angeles engulfed in flames in this way in my lifetime. As someone who has devoted years to studying climate science and advocating for climate technology solutions, I'm still caught off guard by the immediacy of these disasters. A part of me wants to believe the intensifying hurricanes, floods, and wildfires are merely an unfortunate string of bad luck. Whether through misplaced optimism or a subconscious shield of denial, I hadn't fully processed that these weren't just harbingers of a distant future, but our present reality. The recent fires have shattered that denial, bringing to mind the haunting prescience of the movie Don't Look Up. Perhaps we aren't as wise as we fancy ourselves to be.

The LA fires aren't an isolated incident. They're part of a terrifying pattern: the Canadian wildfires that darkened our skies, the devastating floods in Spain and Pakistan, and the increasingly powerful hurricanes in the Gulf. A stark new reality is emerging for climate-vulnerable cities, and whether we acknowledge the underlying crisis or not, climate change is making its presence felt – not just in death and destruction, but in our wallets.

The insurance industry, with its cold actuarial logic, is already responding. Even before the recent LA fires, major insurers like State Farm and Allstate had stopped writing new home policies in California, citing unmanageable wildfire risks. In the devastated Palisades area, 70% of homes had lost their insurance coverage before disaster struck. While some homeowners may have enrolled in California's limited FAIR plan, others likely went without coverage. Now, the FAIR plan faces $5.9 billion in potential claims, far exceeding its reinsurance backup – a shortfall that promises delayed payments and costlier coverage.

The insurance crisis is reverberating across the nation, and Houston sits squarely in its path. As a city all too familiar with the destructive power of extreme weather, we're experiencing our own reckoning. The Houston Chronicle recently reported that local homeowners are paying a $3,740 annually for insurance – nearly triple the national average and 60% higher than the Texas state average. Our region isn't just listed among the most expensive areas for home insurance; it's identified as one of the most vulnerable to climate hazards.

For Houston homeowners, Hurricane Harvey taught us a harsh lesson: flood zones are merely suggestions, not guarantees. The next major hurricane won't respect the city's floodplain designations. This reality poses a sobering question: Would you risk having your largest asset – your home – uninsured when flooding becomes increasingly likely in the next decade or two?

For most Americans, home equity represents one of the largest components of household wealth, a crucial stepping stone to financial security and generational advancement. Insurance isn't just about protecting physical property; it's about preserving the foundation of middle-class economic stability. When insurance becomes unavailable or unaffordable, it threatens the very basis of financial security for millions of families.

The insurance industry's retreat from vulnerable markets – as evidenced by Progressive and Foremost Insurance's withdrawal from writing new policies in Texas – is more than a business decision. It's a market signal. These companies are essentially pricing in the reality of climate change, whether we choose to call it that or not.

What we're witnessing is the market beginning to price us out of areas where we've either built unsustainably or perhaps should never have built at all. This isn't just about insurance rates; it's about the future viability of entire communities and regional economies. The invisible hand of the market is doing what political will has failed to do: forcing us to confront the true costs of our choices in a warming world.

Insurance companies aren't the only ones sounding the alarm. Lenders and investors are quietly rewriting the rules of capital access based on climate risk. Banks are adjusting mortgage terms and raising borrowing costs in vulnerable areas, while major investment firms are factoring carbon intensity into their lending decisions. Companies with higher environmental risks have faced higher loan spreads and borrowing costs – a trend that's accelerating as climate impacts intensify. This financial reckoning is creating a new economic geography, where access to capital increasingly depends on climate resilience.

The insurance crisis is the canary in the coal mine, warning us of the systemic risks ahead. As actuaries and risk managers factor climate risks into their models, we're seeing the beginning of a profound economic shift that will ripple far beyond housing, affecting businesses, agriculture, and entire regional economies. The question isn't whether we'll adapt to this new reality, but how much it will cost us – in both financial and human terms – before we finally act.
