A handful of Houstonians have been named to the Forbes 30 Under 30 Energy and Green Tech list for 2025.

Kip Daujotas is an investment associate at Aramco Ventures, a $7.5 billion venture capital arm of the world's largest energy company. Houston is the Americas headquarters for Saudi Aramco. Since its inception in 2012, Aramco Ventures has invested in more than 100 tech startups. Daujotas joined the team over two years ago after studying for an MBA at Yale University. He led Aramco’s first direct air capture (DAC) investment — in Los Alamos, New Mexico-based Spiritus.

Also representing the corporate side of the industry, Wenting Gao immigrated from Beijing to obtain an economics degree from Harvard University, then got a job at consulting giant McKinsey, where she recently became the firm’s youngest partner. Gao works on bringing sustainability strategies to energy and materials companies as well as investors. Her areas of expertise include battery materials, waste, biofuels, and low-carbon products.

Last but not least, Houston entrepreneur Rawand Rasheed is co-founder and CEO of Houston-based Helix Earth. He co-founded the startup after earning a doctoral degree from Rice University and co-inventing Helix’s core technology while at NASA, first as a graduate research fellow and then as an engineer. The core technology, a space capsule air filtration system, has been applied to retrofitting HVAC systems for commercial buildings.

Each year, Forbes 30 Under 30 recognizes 600 honorees in 20 categories. The 2025 honorees were selected from more than 10,000 nominees by Forbes staff and a panel of independent judges based on factors such as funding, revenue, social impact, scale, inventiveness, and potential.

Specifically, the Energy & Green Tech category recognizes young entrepreneurs driving innovation that’s aimed at creating a cleaner, greener future.

“Gen Z is one of the fastest-growing groups of entrepreneurs and creators, who are reshaping the way the world conducts business, and our Under 30 class of 2025 proves that you can never begin your career journey too early,” says Alexandra York, editor of Forbes Under 30. “With the expansion across AI, technology, social media, and other industries, the honorees on this year’s list are pushing the boundaries and building their brands beyond traditional scopes.”

Houston corporate venture leader calls for collaboration across sustainable fuel, innovation community

HOUSTON INNOVATORS PODCAST EPISODE 212

When it comes to the future of aviation — namely, making it more sustainable, a rising tide lifts all boats. Or, in this case, planes.

Andrew Chang, managing director of United Airlines Ventures, explains that working together is the key for advancing sustainable aviation fuel, or SAF. That's why United Airlines started the Sustainable Flight Fund, a $200 million initiative with support from industry leaders, including Air Canada, Boeing, GE Aerospace, JPMorgan Chase, Honeywell, Aramco Ventures, Bank of America, Hawaiian Airlines, JetBlue Ventures, and several others.

"We all recognize that we may compete in our core business, but with the importance of sustainable aviation fuel and given that it's an industry that doesn't exist — you can't compete for something that doesn't exist — let's collaborate and work together to explore technologies that can directly or indirectly support the commercialization and production of sustainable aviation fuel," he says on the Houston Innovators Podcast.

Within United Airline Ventures, Chang's job is to find technology to invest in across the aviation industry spectrum — from SAF to digital technologies that will improve the United customer experience. This means working with startups and other organizations to find the best fit — and, because he's based in Houston, one of United's seven key hubs, this means knowing and interacting with local innovators.

"The knowledge base and the capabilities are here — that's undebatable," Chang says of the Houston innovation ecosystem. "The next step is making sure we're accessing, promoting, collaborating, and learning from one another."

Again, as Chang recognizes, collaboration is key to further developing the ecosystem, "so that we're not trying to solve the same problem in a vacuum," he explains.

United Airlines recently signed an offtake agreement with Cemvita Factory, a Houston biotech startup that's working on SAF. Chang discusses this partnership on the show, as well as explaining how he works with other startups and what he's looking for.

Howard Berman, as co-founder and CEO, has been at the helm of Coya Therapeutics as its hit some major milestones — from raising over $20 million in venture investment to taking the company public. Coya's IPO occured in a tough market — only 12 biotech companies went public last year, Berman explains on the Houston Innovators Podcast. To Berman, that just proves how passionate the team was about getting this product to those who need it.

"It really says something for the fortitude and our team to come together to make it happen," he says on the show. "We're able to deliver and execute in a difficult market climate.

"Once you're a public company, you have different expectations," he continues. "But you also have the opportunity to go out and attract additional investors in ways you can't do as a private company." Read more.

Houston-based Fervo Energy bumps up IPO target to $1.82 billion

IPO update

Houston-based geothermal power company Fervo Energy is now eyeing an IPO that would raise $1.75 billion to $1.82 billion, up from the previous target of $1.33 billion.

In paperwork filed Monday, May 11 with the U.S. Securities and Exchange Commission, Fervo says it plans to sell 70 million shares of Class A common stock at $25 to $26 per share.

In addition, Fervo expects to grant underwriters 30-day options to buy up to 8.33 million additional shares of Class A common stock. This could raise nearly $200 million.

When it announced the IPO on May 4, Fervo aimed to sell 55.56 million shares at $21 to $24 per share, which would have raised $1.17 billion to $1.33 billion. The initial valuation target was $6.5 billion.

A date for the IPO hasn’t been scheduled. Fervo’s stock will be listed on Nasdaq under the ticker symbol FRVO.

Fervo, founded in 2017, has attracted about $1.5 billion in funding from investors such as Bill Gates-founded Breakthrough Energy Ventures, Google, Mitsubishi Heavy Industries, Devon Energy (which is moving its headquarters to Houston), Tesla co-founder JB Straubel, CalSTRS, Liberty Mutual Investments, AllianceBernstein, JPMorgan, Bank of America and Sumitomo Mitsui Trust Bank.

Fervo’s marquee project is Cape Station in Beaver County, Utah, the world’s largest EGS (enhanced geothermal system) project. The first phase will deliver 100 megawatts of baseload clean power, with the second phase adding another 400 megawatts. The site can accommodate 2 gigawatts of geothermal energy. Fervo holds more than 595,000 leased acres for potential expansion.

Cape Station has secured power purchase agreements for the entire 500-megawatt capacity. Customers include Houston-based Shell Energy North America and Southern California Edison.

Texas university's new flight academy opens at Houston Spaceport

cleared for takeoff

The vehicles may not have “student driver” stickers on them, but Texas Southern University has moved a dozen planes into its new training facility at the Houston Spaceport, opening the way for student flyers to use the facility.

TSU previously reached a deal with Houston Airports and the City of Houston in 2023 to house its prospective Flight Academy at Ellington Field. At the time, TSU had a small fleet of nine planes for student use, but a $5.5 million investment from the city greatly expanded the space available.

The Flight Academy includes a 20,000-square-foot hangar that serves as a TSU satellite campus. The school now has a fleet of 12 Cirrus SR20 aircraft that were acquired last year through state and alumni funding. An additional 4,500 square feet is used as classroom and office space. An 8,000-gallon fuel tank will support flight training operations.

TSU first launched its Aviation Science Management program in 1986 and added a professional pilot program in 2016. The school is now part of the United Airlines pipeline program and has also forged relationships with Delta and Southwest.

“I want to commend Texas Southern University and Houston Airports for their leadership and partnership in advancing aviation education right here in our city,” Houston City Councilwoman Dr. Carolyn Evans-Shabazz in a press release.

“It connects our students to high-paying, high-demand careers in aviation and aerospace. This is how we grow a city in the right way—by investing in workforce development, aligning education with industry and making sure our residents are prepared to lead in the industries of tomorrow. Houston is already a global leader in aerospace and projects like this strengthen that position even further, especially here at Ellington, where innovation and opportunity continue to take flight.”

The City of Houston signed an agreement to continue funding the academy for five years.

Amazon launches ultrafast, 30-minute delivery service across Houston

Amazon Now

More than 20 years after it redefined fast shipping, Amazon is preparing to raise the bar on consumer expectations again by offering to fulfill customers' most urgent product needs in Houston and other parts of the world in a half-hour or less for an extra fee.

The company, which revolutionized online shopping in 2005 with two-day deliveries for Prime members, is rapidly opening small order-processing hubs in dozens of U.S. and foreign cities to cater to shoppers who can't or don't want to wait for cough medicine to relieve flu symptoms or tomatoes for tonight's dinner salad.

The ultrafast service, called Amazon Now, first launched in India last June. Amazon says 30-minute deliveries now are also available in urban areas of the United States, Brazil, Mexico, Japan, the United Arab Emirates, the United Kingdom.

The mini-warehouses devoted to Amazon Now are about the size of a CVS drugstore. They stock about 3,500 products for expedited delivery, including beer, diapers, pet food, meat, nonprescription medications, playing cards and cellphone charging cables.

“We know that customers love speed and always have,” Beryl Tomay, Amazon’s head of transportation, told The Associated Press on Monday. “What we see customers doing, when we offer faster speeds, are they purchase more from Amazon. And Amazon becomes more top of mind for that or other types of items as well.”

In the U.S., the company first tested Amazon Now in Seattle, the home of its headquarters, and in Philadelphia. Most residents of the Dallas-Fort Worth area and Atlanta now have access as well. The service is also live in Dallas-Fort Worth, Denver, Minneapolis, Phoenix, Oklahoma City, Orlando, and dozens of other cities, Amazon said, with New York City and others expected by year-end.

The service charges for Amazon Now start at $3.99 for Prime members, who pay an annual fee of $139, and $13.99 for non-members. A $1.99 small basket fee applies to orders under $15, Amazon said.

The company's bet on a need for speed also comes as some consumers are rebelling against rushed deliveries as they weigh the potential impact on the environment and the workers tasked with preparing orders at a rapid rate.

Amazon’s approach
A relentless focus on speed helped Amazon build a logistics and e-commerce empire. After it made two days the new delivery time normal, Amazon moved into one-day and same-day deliveries for its Prime members. This spring, the company began making 90,000 products available in one hour or three hours at an extra cost.

The scaled down and sped up microhubs that are designed to handle 30-minute orders represent another step in Amazon's pursuit.

Only a handful of people prepare orders from aisles of shelves in the 5,000- to 10,000-square-foot facilities, unlike the sprawling fulfillment centers storing millions of items where Amazon employs a mix of human workers and robotics to pick and pack orders.

Amazon tailors the product inventory to each location and uses artificial intelligence and other technology to analyze what customers buy, as well as when and how often. The most popular U.S. purchases so far include soap, toothpaste, mouthwash, toilet plungers, bananas, limes and wireless earbuds, Amazon said.

The competition
Amazon’s attempt to up the instant gratification ante provides direct competition to on-demand food delivery platforms like Instacart, Uber Eats, DoorDash and Grubhub, which don't have the scale of the e-commerce titan, according to independent retail analyst Bruce Winder.

“What Amazon brings is their prowess in supply chain,” Winder said.

These smaller companies said they don't see Amazon as a threat, though, citing the hundreds of thousands of items they are able to deliver to users' doorsteps by partnering with various merchants and restaurants.

“DoorDash has a mission to empower grocers and retailers and augment their existing footprint, not to replace them,” DoorDash spokesperson Ali Musa said in an emailed statement. “We win only when they win, which is how we can offer over half a million grocery and retail items in under an hour across the country.”

Amazon also is in a race with Walmart to become the retailer that reliably gets orders to online shoppers in under an hour.

For an additional $10 on top of standard delivery charges, shoppers can place Walmart Express Delivery orders from among more than 100,000 products that are guaranteed to arrive in an hour. Many customers, however, are receiving the items under 30 minutes, Walmart CEO John Furner told analysts in February.

Domino's cautionary tale
Companies have promised deliveries in 30 minutes or less before, but the landscape also is littered with failed attempts to break the speed barrier.

The COVID-19 pandemic produced a flurry of companies that promised 10- to 15-minute grocery deliveries from microwarehouses in dense neighborhoods, according to Sucharita Kodali, an analyst at market research firm Forrester Research.

But soaring operating costs, low customer loyalty and the drying up of investor money ultimately caused most to fail before the pandemic was over, analysts said.

Domino’s in 1984 pushed a guarantee that customers would receive their pizzas for free if they weren't delivered in under a half-hour. The company amended the “30 minutes or it’s free” policy after two years, providing only a $3 discount for late deliveries.

The promotion helped Domino’s win market share, but it ended up tarnishing the company's reputation. It dropped the guarantee in December 1993 after a string of crashes and lawsuits involving drivers racing to meet the deadline.

Brad Jashinsky, a retail analyst at information technology research and consulting firm Gartner, said he thinks Amazon should take the pizza chain's experience as a cautionary tale.

“You get in trouble when you start overpromising something like that,” he said.

Amazon won't be making any time guarantees and instead plans to keep customers who chose the 30-minute delivery option updated on the progress of their orders, Tomay said.

“There's no rushing either in our building workers or the gig workers,” she said.

Taking it slow
Kodali thinks Amazon will need a lot of people placing orders around the same time from the same or adjacent apartment buildings for the 30-minute service to be cost-effective.

Consumers may appreciate rapid receipt of products like toilet paper and batteries, but retailers and logistics experts said they also see some online shoppers, especially members of Generation Z, choosing no-rush shipping for products they don't need in a hurry.

Amazon for several years has invited customers to skip one- or two-day delivery and to receive their orders on the same day in as few parcels as possible. Consolidating orders into fewer packages by electing to have them delivered at the same time cuts down on boxes, shipping envelopes and fuel use, analysts said.

“The millennials who came to age in an era that was on fast delivery came to expect it de facto, whereas ... Gen Z is more accepting of a slower speed than previous generations before them,” said Darby Meegan, a general manager at Flexport, a supply chain and logistics company that fulfills orders for thousands of online merchants.

Still, Amazon executives have cited positive early results for Amazon Now in India, where they said Prime members tripled their requests for 30-minute deliveries once they started using the service.

Amazon Now also is attracting more repeat American customers, Tomay said.

“It’s in early days and time will tell,” she said. “I think that it will be interesting to see how it evolves.”
