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 startup raises $6M to scale home-based healthcare platform

fresh funding

As healthcare systems race to expand care beyond hospitals and into the home, investors are placing bigger bets on the infrastructure needed to make that shift possible.

This month, Rosarium Health announced it has raised $6 million in seed funding led by Kalos Ventures, with participation from ResilienceVC, Rock Health Capital, Symphonic Capital, Black Tech Nations Ventures and others.

The investment will help the Houston-based startup continue to build its platform, which features a national network of 800-plus clinicians and 3,000-plus contractors to coordinate home accessibility upgrades and modifications for seniors and people living with disabilities.

For founder and CEO Cameron Carter, the company’s mission grew out of firsthand caregiving experiences.

“From my own personal caregiving experiences, I realized that the benefits exist on paper, but not in reality,” Carter said in a news release. “Families are being left to figure out the paperwork and installations all on their own, which shouldn’t be how this works.”

While Medicare Advantage and Medicaid plans have expanded coverage for home-based services and accessibility modifications, the logistics behind delivering those services often remain fragmented.

Rosarium’s platform coordinates the entire process, from clinical assessments and referrals to contractor management, documentation, reimbursement and installation.

“A clinician can document that a home isn’t safe and a plan can approve a benefit, but there’s no one that’s responsible for making sure the work actually gets done,” Carter says. “We built the missing piece.”

The company was founded in 2021 as Rose Health and was a 2023 participant in the Texas Medical Center’s Accelerator for HealthTech program. It has scaled quickly, building a network of more than 800 clinicians and 3,000 contractors across 34 states.

Rosarium is currently in-network for 1.2 million Medicare and Medicaid lives, with projected coverage expected to reach nearly 4 million by the end of the year, according to the release.

“We’re excited to back Cameron because he and the team at Rosarium are building the infrastructure healthcare needs right now to make the home a safe and comfortable place of care,” Kate Ballinger, investor at Kalos Ventures, added in the release.

As part of the recent investment, Ballinger will join Rosarium’s board of directors.

With eyes on the future, Rosarium plans to grow its partnerships with Medicaid and Medicare Advantage plans, including CalViva and Community Health Plan of Imperial Valley, strengthening its presence in California while expanding access to underserved communities.

Additionally, Carter predicts that home-based healthcare will be part of a broader transformation happening across the industry.

“There’s a growing recognition that health outcomes are shaped by what happens in the home,” he said in the release. “The future of healthcare isn’t just treating people after something goes wrong. It’s creating environments that help prevent those problems in the first place.”

4 Houston-area institutions get $8M for cancer research facilities

fighting cancer

Cancer research capabilities in the Houston area just got an $8 million boost.

On Wednesday, May 20, the Cancer Prevention and Research Institute of Texas (CPRIT) awarded $8 million in grants to institutions in Houston and Bryan for the creation or expansion of so-called “core” cancer research facilities.

“Core facilities provide shared access to advanced technology, equipment, and scientific expertise that may not be available at every institution,” CPRIT says. “These core facilities are vital to not only cancer research but also to the study of diseases beyond cancer.”

Houston-area recipients of these $2 million grants are:

  • A facility at the University of Texas Health Science Center for preclinical support of cancer researchers in Texas to evaluate new safe, effective drugs and drug combinations.

  • $250,000 to the University of Texas Medical Branch at Galveston for a novel therapeutic to prevent colitis-related colorectal cancer.

Axiom Space launches Japanese subsidiary, names leadership

Axiom Space is setting up a Japanese subsidiary to tap into billions of dollars worth of business opportunities in the vast Asia-Pacific region. The company’s new office in Japan will open July 1.

“For the Asia-Pacific region, an Axiom Space presence in Japan means a long-term, direct path to low-Earth orbit for research, for industry, for astronauts, and a partner committed to building that future together with Japan,” Jonathan Cirtain, president and CEO of Axiom Space, said in a news release.

Asia-Pacific spaceflight leaders include Japan, China, India and South Korea.

Until committing to the Asia-Pacific subsidiary, Axiom focused primarily on the U.S. market for space exploration equipment, technology and services. Axiom is building the successor to the International Space Station (ISS), and it provides human spaceflight services and develops next-generation spacesuits.

Fortune Business Insights estimates the Asia-Pacific market for space technology was valued at $155.3 billion in 2025.

“The region is rapidly expanding due to rapidly expanding government space programs, increasing private sector participation, and rising demand for satellite services across densely populated regions,” says Fortune Business Insights, a market research firm.

The region’s combination of strategic investments, market demand and emerging entrepreneurial systems positions Asia-Pacific “for the fastest growth in the global market,” Fortune Business Insights says.

The market research firm pegs the U.S. market for space technology at $251.8 billion in 2025, making it the world’s largest player in that sector.

Veteran Japanese astronaut Koichi Wakata will lead Axiom Space Japan as chief technology officer in the Asia-Pacific region. The Japanese subsidiary will work with government agencies, research institutions, and industrial partners in Japan to expand hardware development and manufacturing, microgravity research and orbital computing.

Wakata was the Japanese space agency’s first program manager for ISS and the station’s first Japanese commander. He also contributed to the construction of ISS, including the Japanese experiment module Kibo. Wakata retired from the Japanese agency, JAXA, in March 2024.

“Japan intends to remain a leading nation in human space exploration post-ISS, and Japanese industry and academia are ready to play a central role in the commercial era,” Axiom Space said in the release. “Axiom Space Japan is how the company will meet that ambition with a long-term, on-the-ground presence.”
