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.

Solar power promises to shine even brighter in Texas this year.

A new forecast from the U.S. Energy Information Administration (EIA) indicates that for the first time, annual power generation from utility-scale solar will surpass annual power generation from coal across the territory covered by the Electric Reliability Council of Texas (ERCOT).

Solar generation is expected to reach 78 billion kilowatt-hours in 2026 in the ERCOT grid, compared with 60 billion kilowatt-hours for coal, the EIA forecast says. The ERCOT grid supplies power to about 90 percent of Texas, including the Houston area.

“Utility-scale solar generation has been increasing steadily in ERCOT as solar capacity additions help meet rapid electricity demand growth,” the forecast says.

Although natural gas remains the dominant source of electricity generation in ERCOT, accounting for an average 44 percent of electricity generation from 2021 to 2025, solar’s share of the generation mix rose from four percent to 12 percent. During the same period, coal’s share dropped from 19 percent to 13 percent.

EIA predicts about 40 percent of U.S. solar capacity, or 14 billion kilowatt-hours, added in 2026 will come from Texas.

Although EIA expects annual solar generation to exceed annual coal generation in 2026, solar surpassed coal in ERCOT on a monthly basis for the first time in March 2025, when solar generation totaled 4.33 billion kilowatt-hours and coal’s totaled 4.16 billion kilowatt-hours. Solar generation continued to exceed that of coal until August of that year.

“In 2026, we estimate that solar exceeded coal for the first time in March, and we forecast generation from solar installations in ERCOT will continue to exceed that from coal until December, when coal generation exceeds solar,” says EIA. “We expect solar generation to exceed that of coal for every month in 2027 except January and December.”

For 2027, EIA forecasts annual solar generation of 99 billion kilowatt-hours in the ERCOT grid, compared with 66 billion kilowatt-hours of annual coal generation.

In April, ERCOT projected almost 368 billion kilowatt-hours of demand in ERCOT’s territory by 2032. ERCOT’s all-time peak demand hit 85.5 billion kilowatt-hours in August 2023.

“Texas is experiencing exceptional growth and development, which is reshaping how large load demand is identified, verified, and incorporated into long-term planning,” ERCOT President and CEO Pablo Vegas said. “As a result of a changing landscape, we believe this forecast to be higher than expected … load growth.”
