Houston company gets greenlight for liquid hydrogen storage system

CB&I, the storage business of Houston-based energy contractor McDermott International, has gotten a preliminary green light for its design of a cargo containment system for liquid hydrogen.

DNV, a classification body for the maritime industry, extended the preliminary approval for the system’s design. CB&I is working on the project with Shell International Trading and Shipping, which transports crude oil, gas, carbon dioxide, and other cargo.

The Shell transportation unit operates the Suiso Frontier, the world’s first ship for hauling liquid hydrogen (LH2). The vessel can carry 75 metric tons of LH2. The Suiso Frontier, which completed its maiden voyage between Australia and Japan in 2022, is the key component of a $360 million coal-to-hydrogen venture.

CB&I designs and builds storage facilities, tanks, and terminals for energy companies. McDermott provides engineering and construction services for the energy industry.

Cesar Canals, senior vice president of CB&I, says his company’s collaboration with Shell and DNV is “making large-scale liquid hydrogen storage and transport more economical. This approval is a major milestone in making this groundbreaking technology available to all companies looking to build LH2 carriers, and we look forward to the possibilities this brings to advancing the hydrogen energy supply chain.”

The containment system’s design is based on CB&I’s technology for onshore storage of LH2. Over the past 60 years, CB&I has designed and built more than 130 onshore storage tanks for LH2.

“The combined cargo containment system and hull design effort aims to address the energy density challenge, benefitting from LH2’s properties and achieving more energy onboard,” says CB&I. “The cargo containment system was integrated into a concept vessel design developed by Houlder, which includes a hull that is optimized for the low-density cargo around … three large tanks.”

Today, LH2 is transported primarily via trucks and pipelines. The Getting to Zero Coalition, a proponent of zero-emission vessels, says the Suiso Frontier represents the first step toward commercializing a global LH2 supply chain by 2030.

“Maritime distribution of hydrogen promises much more flexible energy transfer than transmission of electricity generated from renewables, especially for longer distances,” according to a sponsored article published by Nature.com.

Houston-based climatech startup Aquanta Vision achieved key milestones in 2025 for its enhanced methane-detection app and has its focus set on future funding.

Among the achievements was the completion of the National Science Foundation’s Advanced Sensing and Computation for Environmental Decision-making (ASCEND) Engine. The program, based in Colorado and Wyoming, awarded a total of $3 million in grants to support the commercialization of projects that tackle critical resilience challenges, such as water security, wildfire prediction and response, and methane emissions.

Aquanta Vision’s funding went toward commercializing its NETxTEN app, which automates leak detection to improve accuracy, speed and safety. The company estimates that methane leaks cost the U.S. energy industry billions of dollars each year, with 60 percent of leaks going undetected. Additionally, methane leaks account for around 10 percent of natural gas's contribution to climate change, according to MIT’s climate portal.

Throughout the months-long ASCEND program, Aquanta Vision moved from the final stages of testing into full commercial deployment of NETxTEN. The app can instantly identify leaks via its physics-based algorithms and raw video output of optical gas imaging cameras. It does not require companies to purchase new hardware, requires no human intervention and is universally compatible with all optical gas imaging (OGI) cameras. During over 12,000 test runs, 100 percent of leaks were detected by NETxTEN’s system, according to the company.

The app is geared toward end-users in the oil and gas industry who use OGI cameras to perform regular leak detection inspections and emissions monitoring. Aquanta Vision is in the process of acquiring new clients for the app and plans to scale commercialization between now and 2028, Babur Ozden, the company’s founder and CEO, tells Energy Capital.

“In the next 16 months, (our goal is to) gain a number of key customers as major accounts and OEM partners as distribution channels, establish benefits and stickiness of our product and generate growing, recurring revenues for ourselves and our partners,” he says.

The company also received an investment for an undisclosed amount from Marathon Petroleum Corp. late last year. The funding complemented follow-on investments from Ecosphere Ventures and Odyssey Energy Advisors.

Ozden says the funds will go toward the extension of its runway through the end of 2026. It will also help Aquanta Vision grow its team.

Ozden and Marcus Martinez, a product systems engineer, founded Aquanta Vision in 2023 and have been running it as a two-person operation. The company brought on four interns last year, but is looking to add more staff.

Ozden says the company also plans to raise a seed round in 2027 “to catapult us to a rapid growth phase in 2028-29.”
