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.

Houston researchers develop dissolvable implant for targeted cancer drug delivery

cancer research

Researchers at Houston Methodist have developed a biodegradable implant that can be used to safely and consistently deliver drug treatments to tumors and then dissolve without the need for further surgery.

The implant is only the size of a grain of rice, but its potential is staggering. The biodegradable nanofibrous drug-eluting seed (b-NDES) works as a reservoir parked inside a soft tumor, where it can slowly release immune-stimulating drugs over time. This overcomes a consistent problem with drugs such as immune checkpoint inhibitors. Normal systemic administration sees comparatively little of the drug making its way to the tumor, with most of it circulating throughout the body. The b-NDES is like deploying a small guerrilla fighting force embedded in enemy territory, doing maximum damage to the entrenched tumor.

"To improve cancer treatment, we're trying to start a fire inside the tumor itself," Corrine Chua, associate professor in the Center for BioNanoengineering at Houston Methodist Research Institute, said in a news release. "By activating immune cells directly within the tumor microenvironment, those cells can then travel throughout the body and seek out cancer wherever it exists. The b-NDES platform was developed to help keep therapeutic drugs concentrated inside tumors while minimizing exposure to healthy tissues.”

Chua co-led the study with Alessandro Grattoni, chair and director of the Center for BioNanoengineering at Houston Methodist Research Institute.

The study included support from the Nancy Owens Breast Cancer Foundation and the National Institutes of Health/National Cancer Institute.

Chau and Grattoni used preclinical models of triple-negative breast cancer, an aggressive form of cancer that is estrogen receptor-negative, progesterone receptor-negative and HER2-negative. Because of the receptor negativity, some popular treatments like tamoxifen and trastuzumab are ineffective. Chemotherapy has been shown to be the best course of action.

The b-NDES implant is deployed alongside radiation drugs. It keeps the drugs focused on the tumor, reducing the amount of harmful side effects typically seen when drugs are circulated more widely in the body. In 60 percent of the models, tumors were eliminated and did not cause side effects beyond the tumor site. Once the drugs have been deployed, the implant breaks down naturally.

While promising, more research will have to be done to expand use to other tumor types.

"Although the study focused on triple-negative breast cancer models, the approach could have broader applications for solid tumors," Grattoni added in the release. "It could potentially be used in cancers where there is a tumor lesion accessible for placement, including pancreatic or lung cancers."

New Houston platform Same Day Reels launches for on-demand content creation

In The Moment

If an event doesn't happen on Instagram, did it even really happen? In today's social media-driven age of branding and audience engagement, the answer increasingly is no.

Houston entrepreneur Karen De Amat is looking to fill the online content creation needs of companies with her new venture, Same Day Reels, which launched in early August. It will serve as a platform to connect companies and brands with talent that can help turn an event into a viral moment as it is happening.

"Events move quickly, and social media moves even faster,” said De Amat. “Same Day Reels was built to help brands capture the moment while it still matters. We are creating a more efficient way for businesses and creators to work together. Brands need content faster, and creators need more opportunities to turn their talent into real work. Same Day Reels brings those needs together.”

The company is focused on adding livestreams and concurrent short video content to "activations, launches, fundraisers, grand openings, conferences, hospitality experiences, and private celebrations." Such content can significantly increase the visibility of a product or brand according to digital marketing brands like Wyzowl, whose data found 63 percent of people in 2026 prefer to learn about new products via short video.

Packages offered by Same Day Reels will include filming, editing, and publishing content within hours of the targeted event.

De Amat says that her content creation platform will be a way to preserve the excitement of events and launches by enshrining them with immediate social media-driven memories.

“Event content is no longer just something you post after the fact,” De Amat said. “It is part of how people experience, remember and share the moment.”

Previously, De Amat is also the founder and CEO of Social Behavior, an influencer marketing company she launched from her home in 2014. It quickly garnered an array of clients and thrust De Amat into the spotlight, including numerous appearances on Fox 26's The Isiah Factor. Influencer Marketing Hub named her one of the top CEOs of influencer marketing companies in Houston in 2025.
