Researchers at Rice University have developed a catalyst that could render steam methane reforming, or SMR, entirely emission-free by using light rather than heat to drive the reaction.

The researchers believe the work could prove to be a breakthrough for extending catalyst lifetimes. This will improve efficiencies and reduce costs for a number of industrial processes that are affected by a form of carbon buildup that can deactivate catalysts called coking.

The new copper-rhodium photocatalyst uses an antenna-reactor design. When it is exposed to a specific wavelength of light it breaks down methane and water vapor without external heating into hydrogen and carbon monoxide. The importance of this is it is a chemical industry feedstock that is not a greenhouse gas. Rice’s work also shows that the antenna-reactor technology can overcome catalyst deactivation due to oxidation and coking by employing hot carriers to remove oxygen species and carbon deposits, which effectively regenerates the catalyst with light.

The new SMR reaction pathway build off a 2011 discovery from Peter Nordlander, Rice’s Wiess Chair and Professor of Physics and Astronomy and professor of electrical and computer engineering and materials science and nanoengineering, and Naomi Halas. They are the authors on the study about the research that was published in Nature Catalysis. The study showed that the collective oscillations of electrons that occur when metal nanoparticles are exposed to light can emit “hot carriers” or high-energy electrons and holes that can be used to drive chemical reactions.

“This is one of our most impactful findings so far, because it offers an improved alternative to what is arguably the most important chemical reaction for modern society,” Norlander says in a news release.

The research was supported by Robert A. Welch Foundation (C-1220, C-1222) and the Air Force Office of Scientific Research (FA9550-15-1-0022) with the Shared Equipment Authority at Rice providing data analysis support.

“This research showcases the potential for innovative photochemistry to reshape critical industrial processes, moving us closer to an environmentally sustainable energy future,” Halas adds.

Hydrogen has been studied as it could assist with the transition to a sustainable energy ecosystem, but the chemical process responsible for more than half of the current global hydrogen production is a substantial source of greenhouse gas emissions.Hydrogen is produced in large facilities that require the gas to be transported to its point of use. Light-driven SMR allows for on-demand hydrogen generation,which researchers believe is a key benefit for use in mobility-related applications like hydrogen fueling stations or and possibly vehicles.

Houston startup founders report on clean energy tech efficacy

seeing results

A team from Rice University has uncovered an inexpensive, scalable way to produce clean-burning hydrogen fuel.

In research published this month in the journal Science, researchers from Rice’s Laboratory for Nanophotonics, in partnership with Syzygy Plasmonics Inc. and Princeton University’s Andlinger Center for Energy and the Environment, detail how they converted ammonia into carbon-free fuel using a light-activated catalyst.

The new catalyst separates the liquid ammonia into hydrogen gas and nitrogen gas. Traditional catalysts require heat for chemical transformations, but the new catalyst can spur reactions with just the use of sunlight or LED light.

Additionally, the team showed that copper-iron antenna-reactors could be used in these light-driven chemical reactions, known as plasmonic photocatalysis. In heat-based reactions, or thermocatalysis, platinum, and related precious (and expensive) metals like palladium, rhodium, and ruthenium are required.

“Transition metals like iron are typically poor thermocatalysts,” Naomi Halas, a co-author of the report from Rice, said in a statement. “This work shows they can be efficient plasmonic photocatalysts. It also demonstrates that photocatalysis can be efficiently performed with inexpensive LED photon sources.”

Halas, Rice's Stanley C. Moore Professor of Electrical and Computer Engineering, was joined on the project by Peter Nordlander, Rice’s Wiess Chair and Professor of Physics and Astronomy, and Rice alumni and adjunct professor of chemistry Hossein Robatjazi. Emily Carter, the Gerhard R. Andlinger Professor in Energy and Environment, represented Princeton University.

“These results are a great motivator," Carter added. "They suggest it is likely that other combinations of abundant metals could be used as cost-effective catalysts for a wide range of chemical reactions.”

Houston-based Syzygy, which Halas and Nordlander founded in 2018, has licensed the technology used in the research and has begun scaled-up tests of the catalyst in the company’s commercially available, LED-powered reactors. According to Rice, the test at Syzygy showed the catalysts retained their efficiency under LED illumination and at a scale 500 times larger than in tests in the lab setup at Rice.

“This discovery paves the way for sustainable, low-cost hydrogen that could be produced locally rather than in massive centralized plants,” Nordlander said in a statement.

Earlier this month, Syzygy closed its $76 million series C round to continue its technology development ahead of future deployment/

Houston is home to many other organizations and researchers leading the charge in growing the hydrogen economy.

Earlier this year, Mayor Sylvester Turner announced he's determined to position the city as hub for hydrogen innovation as one of the EPA's Regional Clean Hydrogen Hubs. Organizations in Texas, Southwest Louisiana and the surrounding Gulf Coast region, known and HyVelocity Hub, also announced this month that it would be applying for the regional funding.

And according to a recent report from The Center for Houston's Future, the Bayou City is poised to "lead a transformational clean hydrogen hub with global impact."

Houston sportstech startup shoots, scores in Pharrell Williams competition

on the rebound

Anyone who's witnessed even just a minute of basketball knows how important accuracy is in sinking shots on the court. One Houston startup has developed a device to help practice make perfect in a game.

GRIND’s portable basketball shooting machine, the first of its kind, was created by founder and CEO Thomas Fields, former basketball phenom at Houston’s Reagan High School (now Heights High School).

“I remember being on varsity as a freshman and shooting thousands of shots every day trying to be the best,” says Fields. “My school bought a shooting machine, but they never let me use it. It was a game-changing piece of equipment, and I didn’t even have access because the gyms were always closed or closing.

“And another major problem was getting your rebounds, so we set out to make a portable basketball rebounding machine, so you could take it anywhere like home, the park, or the gym. It was also important to make it affordable, too.”

At just 110 pounds, the GRIND shooting machine is 54 percent lighter than other home shooting machines, has a 12-foot net, and needs just 90 seconds to set up or take down.

“Our portable shooting machine has been on the market for about three, four years now,” says Fields. “So now it's time to kind of accelerate the growth, and that’s pretty exciting. We really have our sights on NBA Africa for a partnership there. Another one is Adidas; we are collaborating with them right now and they're also one of the sponsors of Black Hat Mission. And hopefully, we would like to land some NBA guys to invest and really get behind our sportstech company, but also make a significant impact in the community by getting kids into tech through sports.”

To that end, GRIND recently won second place in a competition from Black Ambition, an organization founded by Pharrell Williams. With the tagline, “Uninterrupted ambition. Unmatched impact,” the Black Ambition Prize celebrates underrepresented founders globally.

“When I initially heard of Black Ambition, I just kind of heard that Pharrell had started a venture fund aimed at uplifting black and brown entrepreneurs,” says Fields. “And when I read more about it, I realized that their mission perfectly aligned with GRIND. Our goal is to try to get kids into tech and STEM, but use sports as the conduit and the bridge to get them there.

“We applied for the million-dollar cash prize for first place, but took second place, which is a $250,000 investment in the company. So now that Pharrell and Black Ambition are behind us, we are going out and raising some more capital to hit that hyper stage that we're going into. We are launching our software next year and our hardware has really been growing.”

Fields pitched GRIND on Shark Tank in May of 2021, where he was offered a joint deal for $250,000 for 25 percent of the company from both Mark Cuban and Barbara Corcoran. While Fields agreed on the show, the finalized terms of the deal were not disclosed.

As a startup, GRIND, a consumer brand developing the world’s first smart ecosystem of sports equipment products, represents the continued uptick with sportstech innovation in Houston.

“We want to revolutionize the world of sports equipment by leveraging cutting edge technology by developing sports equipment that can seamlessly connect to software, enhancing athletic performance, and pushing athletes to achieve their peak potential,” Fields says.

As GRIND continues to push forward and expand its footprint, it’s also looking to expand its customer base.

“I think the target users are middle school and high school athletes,” says Fields. “These are the kids that are striving to be great athletes and striving to get into college. We also have colleges that have our product, as well. But mostly, the customer is the parents of those athletes. That's really who we're trying to get excited.

“And then, of course, there are the coaches and trainers. They own gyms; they own organizations and need equipment for their schools and universities. That's another target customer of ours for sure.”

Ultimately, GRIND will continue to build on Fields’ initial inspiration to design products and technologies with the athletes — especially hoopers — in mind.

“Our goal in the next few years is to really amp up the scholarships that we facilitate to funnel kids into STEM tech careers and pathways,” says Fields. “GRIND Day, which is a proclamation the City of Houston gave us for August 12 each year, is a day where we bring sports, tech, and culture all under one umbrella. Kids see us using 3D printers and lasers to cut the products that we make in our warehouse, which is in an underserved community, which hopefully makes them think it’s cool and want to get into technology.”

Houston airport cut traffic congestion by 99 percent during peak travel season

A Soaring Improvement

Years of physical improvements and other initiatives paid off this holiday season at George Bush Intercontinental Airport (IAH). Despite seeing a record number of flyers, traffic congestion at the airport dropped by an astounding amount.

“Our goal was to deliver a seamless journey during one of the busiest travel seasons of the year,” said Jim Szczesniak, director of aviation for Houston Airports. “The results show that our investments in infrastructure, technology and customer service are paying off. We are proud of our team and the traveling public for working together to make this holiday season a success. Our coordinated efforts between Houston Airports and Houston Police kept traffic flowing smoothly at our departure curbs while passengers followed instructions and used cell phones lots effectively. These efforts, paired with infrastructure improvements like the new International Arrivals Curb and expanded Terminal C garage entrance, demonstrate our commitment to delivering world-class service and efficiency.”

The holiday flying season officially lasts from December 20 to January 6. Data from Houston airports shows that between December 20 and December 30, 1.7 million passengers passed through IAH, a 21 percent increase over the same period in 2023. However, the number of heavy traffic periods fell 90 percent and periods of severe traffic fell 99 percent. To put it another way, passengers at IAH spent 4.4 hours in severe traffic during Christmas 2023. This past Christmas, it was just 2 minutes, an astounding reduction.

This was accomplished with the long-awaited new IAH International Arrivals Curb, which opened for public use on December 14. The new arrivals curb features seven lanes for dedicated drop-off and pick-up, greatly increasing the places for passengers to enter and exit the airport. IAH also opened the previously closed entry roadway lane before Thanksgiving, further reducing traffic snarl.

For those leaving their cars at the airport, a new cashless, automated system was built at HAS garages and ecoparks. New curbside agents were also hired, and Houston police helped direct traffic during the stressful and busy time.

“Our focus is always on providing a safe, stress-free experience,” said Kelly Woodward, chief operating officer for Houston Airports. “These upgrades allowed us to accommodate record passenger numbers while keeping traffic flowing. It’s a win for travelers and our city.”

IAH will continue to improve in 2025 as the new International Central Processor terminal comes fully online. As IAH becomes one of the main Gateways to Latin and South America, it will continue to serve the increasing number of flyers heading south of the border. Some time in 2025, 11 new lanes will open on the upper level, keeping traffic moving briskly.

Houston construction tech tool acquires Y Combinator-backed co.

M&A moves

A Houston-based platform that connects skilled electricians with top electrical contractors has made a strategic acquisition.

Buildforce announced it has acquired Ladder, which is a Y Combinator-backed, technology-enabled construction labor marketplace.

The acquisition is part of Buildforce’s expansion plans into the southeastern U.S. and during a time of increased demand for skilled construction talent. Buildforce will work to leverage the Ladder customer base of over 200 customers across six states, as well as its extensive electrician network of over 10,000 pre-screened electricians, which is the largest in the Southeast.

In addition to expanding to Georgia with the Ladder acquisition, Buildforce launched in Arizona in October and will expand into several additional high-construction volume states in 2025. Also in October, Buildforce launched an easier product to manage a flexible time approval process with its Activity Log and Comments for Time Entries update. Contractors in these regions will be introduced to a more “integrated, technology-driven approach to talent acquisition and workforce management that drives efficiency and delivers higher quality project outcomes,” according to Buildforce.

“There are two major problems plaguing the construction labor market,” Moody Heard, co-founder and CEO of Buildforce, says in a news release. “One, the project-based nature of construction work means tradesmen are constantly ‘working themselves out of a job’, meaning high employee turnover. And two, the industry is experiencing a secular decline in the supply of tradesmen relative to surging demand.”

Ladder Founder and CEO Alex Stewart will continue on in a leadership role as a senior executive with Buildforce.

"I am incredibly excited to join the Buildforce team to further its expansion into new markets, while staying true to its mission of helping people in the construction trades find more security and fulfillment,” Stewart said in a news release. “Buildforce is at the forefront of workforce management for the construction industry, and I look forward to working with Moody and the rest of the talented Buildforce team to drive the business towards continued growth.”

Buildforce was founded in 2019 to help close the gap in the construction labor market that affected skilled tradespeople and contractors. In 2021, the company raised a $4 million round backed by Houston-based Mercury.
