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 Nobel Prize nominee earns latest award for public health research

Prized Research

Houston vaccine scientist Dr. Peter Hotez can add one more prize to his shelf.

Hotez — dean of the National School of Tropical Medicine and professor of Pediatrics and Molecular Virology & Microbiology at Baylor College of Medicine, co-director of the Texas Children’s Center for Vaccine Development (CVD) and Texas Children’s Hospital Endowed Chair of Tropical Pediatrics — is no stranger to impressive laurels. In 2022, he was even nominated for a Nobel Peace Prize for his low-cost COVID vaccine.

His first big win of 2025 is this year’s Hill Prize, awarded by the Texas Academy of Medicine, Engineering, Science and Technology (TAMEST).

Hotez and his team were selected to receive $500,000 from Lyda Hill Philanthropies to help fund The Texas Virosphere Project. The endeavor was born to help create a predictive disease atlas relating to climate disasters. Because the climate crisis has ushered in changes to the distribution of diseases, including dengue, chikungunya, Zika, Chagas disease, typhus and tick-borne relapsing fever, it’s important to predict outbreaks before they become a menace.

Rice University researchers are collaborating with Hotez and his team on a project that combines climate science and metagenomics to access 3,000 insect genomes. The goal is to aid health departments in controlling disease and informing policy.

The Hill Prize, which is being awarded to six innovators for the first time, thanks to a $10 million commitment from the philanthropic organization, is intended to back ideas that are high-risk and high-reward. Each of the projects was chosen for its potential real-life impact on some of Texas's — and the world’s — most challenging situations. Hotez’s prize is the first Hill Prize to be given in the realm of public health. The additional winners are:

  • Hill Prize in Medicine: Kenneth M. Hargreaves, D.D.S., Ph.D., The University of Texas Health Science Center at San Antonio
  • Hill Prize in Engineering: Joan Frances Brennecke, Ph.D. (NAE), The University of Texas at Austin
  • Hill Prize in Biological Sciences: David J. Mangelsdorf, Ph.D. (NAM, NAS), UT Southwestern Medical Center
  • Hill Prize in Physical Sciences: James Chelikowsky, Ph.D., The University of Texas at Austin
  • Hill Prize in Technology: Robert De Lorenzo, M.D., EmergenceMed, LLC

How Houston's cost of living compares to other major Texas cities in 2025

Calculating Costs

A new cost-of-living index yields a result that many Houstonians will find surprising: Houston is not the most expensive place to live in Texas. Dallas and Austin are costlier.

Numbeo’s cost-of-living index for 2025 shows Dallas ranks first in Texas and 24th in North America, landing at 65.8. The cost-of-living index compares the cost of living in New York City (which sits at 100) with the cost of living in another city. Austin is at 61.7, Houston at 60.6, and San Antonio at 58.8.

Houston ranks 40th overall in North America, out of 52 cities in the index.

Numbeo’s cost-of-living index takes into account the cost of items like groceries, restaurant meals, transportation, and utilities. The index excludes rent.

When rent is added to the cost-of-living index, Houston is still third among Texas cities. Dallas grabs the No. 21 spot in North America (57.1), one notch above Austin (56.6). Houston ranks 35th (51.4), and San Antonio ranks 42nd (34.6).

Rent index
While Dallas holds the top Texas spot on Numbeo’s overall cost-of-living index, Austin faces the highest rent prices. Numbeo's rent index for Austin sits at 50.1, putting it in 12th place among major cities in North America and highest in Texas, above the indexes for Dallas, Houston, and San Antonio. Houston lands at 27th.

The rent index in New York City, which tops the list, is 100. As Numbeo explains, the rent index estimates the cost of renting an apartment in a city compared with New York City. If the rent index is 50, for example, this suggests the average rent in that city is 50 percent below the average rent in New York City.

Around Texas, the rent index is:

  • 46.2 in Dallas
  • 39.8 in Houston
  • 34.6 in San Antonio

Restaurant index
In contrast to its showing on the rent and cost-of-living indexes, Houston outranks Dallas, Austin, and San Antonio on Numbeo’s restaurant index. This index compares the prices of meals and drinks at restaurants and bars to those in New York City.

Houston sits at No. 25 on the restaurant index, at 68.9. Dallas comes in at No. 32 (67.1), Austin at No. 34 (66.6), and San Antonio at No. 36 (65.2).

The National Restaurant Association reported in December that menu prices in the U.S. had risen 3.6 percent in the past 12 months, outpacing gains in grocery prices and the federal government’s overall Consumer Price Index. Fortunately for diners, that was the smallest 12-month increase in menu prices since August 2020, according to the association.

Toast, which provides a cloud-based restaurant management system, says the higher menu prices reflect higher food prices.

“Food prices have been increasing due to inflation, labor expenses, fuel costs, and supply chain disruptions, all of which impact restaurant profitability, Toast says. “While raising menu prices is one option to combat rising food costs, some restaurants have introduced service charges and simplified menus to avoid passing all costs onto customers.”

Houston startup taps strategic partner to produce novel 'biobased leather'

cleaner products

A Houston-based next-gen material startup has revealed a new strategic partnership.

Rheom Materials, formerly known as Bucha Bio, has announced a strategic partnership with thermoplastic extrusion and lamination company Bixby International, which is part of Rheom Material’s goal for commercial-scale production of its novel biobased material, Shorai.

Shorai is a biobased leather alternative that meets criteria for many companies wanting to incorporate sustainable materials. Shorai performs like traditional leather, but offers scalable production at a competitive price point. Extruded as a continuous sheet and having more than 92 percent biobased content, Shorai achieves an 80 percent reduction in carbon footprint compared to synthetic leather, according to Rheom.

Rheom, which is backed by Houston-based New Climate Ventures, will be allowing Bixby International to take a minority ownership stake in Rheom Materials as part of the deal.

“Partnering with Bixby International enables us to harness their extensive expertise in the extrusion industry and its entire supply chain, facilitating the successful scale-up of Shorai production,” Carolina Amin Ferril, CTO at Rheom Materials, says in a news release. “Their highly competitive and adaptable capabilities will allow us to offer more solutions and exceed our customers’ expectations.”

In late 2024, Rheom Materials started its first pilot-scale trial at the Bixby International facilities with the goal of producing Shorai for prototype samples.

"The scope of what we were doing — both on what raw materials we were using and what we were creating just kept expanding and growing," founder Zimri Hinshaw previously told InnovationMap.

Listen to Hinshaw on the Houston Innovators Podcast episode recorded in October.
