On an island almost 4,000 miles away, a company is creating research-based tech innovation that's sending ripple effects across the Pacific Ocean to Houston's energy ecosystem.

While Oceanit, founded in 1985 by Patrick Sullivan, is based in Hawaii, a portion of its customer base is based right here in Houston.

“We are, indeed, in the middle of the sea, but we work around the world,” Sullivan, who serves as president and CEO of his company, says on the Houston Innovators Podcast. “What we do in Houston is interesting because we consider Houston the center of energy. And energy makes the world go around, and there’s just no two ways around it. Of course, there’s lots of transition going on, so it’s an exciting time to be doing energy.”

In fact, realizing how much business opportunity there is in Houston, Oceanit recently opened H2XCEL — short for “Hydrogen Accelerator” — locally, aiming to integrate hydrogen into the current energy infrastructure.

H2XCEL will be the only lab in the U.S. capable of testing hydrogen and methane mixtures at high temperatures and pressures. Its aim is to protect pipelines from hydrogen embrittlement — when small hydrogen molecules penetrate pipe walls and damage the metal, potentially causing cracks, leaks, and failures.

The facility acts as a demonstration opportunity for Oceanit to test and show how hydrogen could be transferred via existing infrastructure.

"We can test to failure right there in Houston," Sullivan says on the show. “We’re talking to all the pipeline companies about getting their steel pipe and running through all these tests to show how it’s going to perform with all these different mixtures."

“The idea is to get the community to see that when you integrate technology from different fields into the energy space, we can keep making progress,” he continues.

Hydrogen embrittlement prevention is just one piece of what Oceanit's team is working to find solutions for. Sullivan describes his company as a 'Mind to Market' approach to industry. His business model includes some venture capital backing, but he says he prefers to partner with customers directly, explaining that the type of technology Oceanit deploys takes time and customization. This corporate co-development, as he explains, is Oceanit's unique approach to disruption.

There are so many opportunities within the energy transition to innovate, as Sullivan says, and it's not just one thing that's going to move the needle. The transition will require many different types of tech.

"It’s going to take time," he says. "But if we start reducing carbon and the use of fossil fuel today, we buy time for the planet."

Hawaii-based tech company opens new lab in Houston to enhance hydrogen pipeline safety

HOU-DRYGEN

An innovative Hawaii-based technology company is saying aloha to Houston with the opening of a unique test laboratory that aims to increase hydrogen pipeline safety. It is the latest sign that Houston is at the forefront of the movement to hydrogen energy.

The lab, H2XCEL — short for “Hydrogen Accelerator” — aims to integrate hydrogen into the current energy infrastructure, a serious cost-saver for companies looking to make the energy transition. Oceanit, a Honolulu-based technology company, is behind the lab.

H2XCEL will be the only lab in the U.S. capable of testing hydrogen and methane mixtures at high temperatures and pressures. Its aim is to protect pipelines from hydrogen embrittlement — when small hydrogen molecules penetrate pipe walls and damage the metal, potentially causing cracks, leaks, and failures.

“The launch of this testing facility is a major milestone. It is the only lab of its kind in the U.S. and the work underway at H2XCEL will accelerate the transition toward a hydrogen-driven economy,” Patrick Sullivan, the CEO and founder of Oceanit, says in a news release. “We see a toolset emerging that will enable the U.S. to accelerate toward a low-carbon future.”

Houston was the obvious choice to launch the new lab, says Oceanit’s Direct of Marketing James Andrews.

“Houston is the energy capital of the world," Andrews explains. "Oceanit knew that if we wanted to make inroads with decarbonization technologies, we needed to be physically present there.”

H2XCEL uses Oceanit’s HydroPel pipeline nanotechnology, developed with the support of the U.S. Department of Energy. It is a surface treatment that protects metals, eliminating the need to build new pipelines using expensive, hydrogen-resistant metals. The estimated cost of building new hydrogen pipelines is approximately $4.65 million per mile, according to a press release from the company. In contrast, HydroPel can be applied to existing pipelines to prevent damage, and the cost to refurbish one mile of existing steel pipeline is less than 10 percent of the cost per mile for new pipeline construction.

One of the main objectives of the new Houston lab will be to test hydrogen-methane blends under varying conditions to determine how to use HydroPel safely. By enabling the energy sector to reduce its climate impact while continuing to provide energy using existing infrastructure, methane-hydrogen blends capitalize on hydrogen’s carbon-free energy potential and its positive impact on climate change.

“We want to create a situation where we can speed up energy transition,” says Andrews. “By blending it into a safer environment, we can make it attractive to bigger players.”

Oceanit already has a Houston presence where the team is focused on several other technologies related to hydrogen, including HeatX, a water-based technology for heat transfer surfaces in refineries, power plants, and more, as well as their HALO system, which utilizes directed energy to produce clean hydrogen wastewater and other waste byproducts produced in industrial businesses.

A recent report issued by Rice University’s Baker Institute for Public Policy about the hydrogen economy

in Texas insists that the Lone Star State is an ideal hub for hydrogen as an energy source. The report explains that with the state’s existing oil and gas infrastructure, Texas is the best spot to affordably develop hydrogen while managing economic challenges. The Houston region already produces and consumes a third of the nation’s hydrogen, according to the report, and has more than 50 percent of the country’s dedicated hydrogen pipelines.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
