With the acquisition of its Texas business now complete, Houston-based Caliche Development Partners is moving ahead with expansion of a natural gas storage project in Beaumont.

This milestone comes after a previously announced majority investment in Caliche by New York City-based investment firm Sixth Street, which has offices in Houston, Austin, and Dallas. Sixth Street recently closed on the Texas portion of the deal, and it expects to wrap up the California portion of the deal in mid-2025.

The amount of Sixth Street’s investment in Caliche wasn’t disclosed.

Completion of the deal’s Texas component gave Caliche the go-ahead to start spending Sixth Street’s money on the Beaumont project.

Caliche already has started construction on the 14 billion-cubic-feet expansion of its Golden Triangle Storage natural gas storage facilities. Two new caverns, expected to come online in 2026 and 2027, will double total storage capacity to 28 billion cubic feet (Bcf).

The Golden Triangle Storage system connects to seven major pipelines in the Beaumont-Port Arthur area.

Meanwhile, Caliche has started construction on what’s billed as the world’s largest helium storage cavern, also located at the Golden Triangle site. This cavern is slated to begin operating in 2025, while Caliche expects its planned carbon sequestration project located just four miles west of Golden Triangle to enter the next phase of the Class VI permitting process by May 2026.

Caliche is an acquisition and development company that specializes in underground storage of natural gas, industrial gasses like hydrogen and helium, and carbon emissions. Caliche’s projects are in the Texas Gulf Coast’s Jefferson County and Northern California’s Colusa County.

Investor acquires majority stake in Houston energy storage, CCS co.

here's the deal

Investment firm Sixth Street has purchased a majority stake in Houston-based Caliche Development Partners, which focuses on buying, developing, and operating natural gas and gas storage facilities along with carbon sequestration projects.

Financial terms weren’t disclosed.

The deal includes Caliche’s Golden Triangle Storage facilities and carbon sequestration project in Beaumont, and its Central Valley Gas Storage facilities in Princeton, California.

Caliche says Sixth Street’s backing will enable it to expand its Golden Storage Triangle complex, including the addition of two natural gas caverns.

Caliche’s leadership will continue to oversee day-to-day operations and remain investors in the company. All employees in Caliche’s Texas and California offices and at its facilities are staying aboard.

“We continue to meet the growing demand for the storage of natural gas and industrial gasses, including helium and hydrogen, and provide the infrastructure for lower environmental impact forms of energy through our commitment to safety, deliverability, [and] asset integrity,” Dave Marchese, CEO of Caliche, says in a news release.

Richard Sberlati, a partner at Sixth Street, which has an office in Houston, says Caliche’s success “comes from a combined 65 years of collective storage experience, and we look forward to partnering with the company’s management as they further grow the business.”

Sixth Street’s acquisition of Caliche’s Texas business operations is expected to close in late 2024, and its acquisition of the California business operations is set to close in mid-2025.

Founded in 2016, Caliche announced in 2020 that it had arranged a $150 million debt facility with Houston-based investment firm Orion Infrastructure Capital. Two years later, Caliche gained $268 million in funding from Orion and Chicago-based asset management firm GCM Grosvenor.

New 160MW battery storage project comes online in Houston

powered on

Colorado-based energy storage company SMT Energy and North Carolina-based software company FlexGen have begun operations of Houston IV, a 160-megawatt utility-scale battery storage facility that aims to support the ERCOT grid.

The companies delivered the project in just six weeks, according to a news release. Mississippi-based Irby Construction Company served as the engineering, procurement, and construction (EPC) partner, and CenterPoint Energy will serve as the interconnecting utility.

“FlexGen’s distinctive combination of software automation, our remote operations center, and on-the-ground field expertise all work together to accelerate battery deployment,” Jason Rislov, SVP of operations at FlexGen, said in the release. “What used to take 25-plus weeks took us six. That time saved translates directly into giving the grid and consumers what they need most right now: a more reliable, resilient energy system.”

Houston IV is one of more than 12 projects that SMT and FlexGen have built to connect to ERCOT, according to Energy Storage News.

“Bringing a 160-MW battery storage facility online in just six weeks required disciplined planning, seamless coordination, and an unwavering focus on safety and quality,” Shaun Coleman, project manager at Irby Construction, said in a news release. “The SMT Energy, FlexGen, and Irby Construction teams coordinated engineering, procurement, and construction to keep every workstream aligned, identify challenges early, and maintain safety and quality at an accelerated pace. That integration is critical, not only to delivering projects quickly, but also to ensuring battery storage facilities perform reliably over the long term.”

Houston IV is expected to store and provide enough electricity to power 8,800 homes in Texas annually. In March, SMT Energy secured $135 million in funding for the project from Macquarie and KeyBanc Capital Markets as joint lead arrangers. SMT and FlexGen broke ground to signal the start of the process in May.

In 2023, SMT Energy and joint venture partner SUSI Partners also announced plans to add 10 battery storage projects to Texas, which would double capacity from 100 megawatts to 200 megawatts in the Houston and Dallas areas.

KBR's Mission Technology Solutions spinoff awarded $1.1B NOAA contract

A Big Deal

Amid a major spinoff, Houston-based KBR's Mission Technology Solutions business has been awarded a five-year contract for up to $1.1 billion from NOAA’s National Weather Service to help predict and combat extreme weather conditions.

Under the follow-on Commercial Data Program National Mesonet Program (CDP NMP) contract, KBR will provide weather and observational data from commercial stations, university and research campuses, and other non-federal providers nationwide. The information collected will assist in predicting severe temperatures and high-impact weather conditions like extreme storms.

"This award underscores KBR's proven track record of delivering vital data that strengthens national forecasting capabilities," Todd May, KBR’s senior vice president of Mission Technology Solutions, said in a news release.

According to a separate release from NOAA, the contract expands upon KBR's existing relationship with the agency. KBR will work with about 70 private industry partners on services such as data recording, collection, aggregation and processing, and will lead the CDP NMP's "network of networks."

“NOAA gathers environmental information from a wide variety of sources, and a growing list of private industry partners have joined our agency to collect this vital data,” Ken Graham, director of NOAA’s National Weather Service, said in the release. “This agreement streamlines the process that turns raw data into the gold-standard forecasts that Americans depend on.”

KBR will utilize its Speed to Mission ImpactSM technology for the project to supply data from across regions, measurement types, and system configurations. Both KBR and NOAA say the expanded data collection contract will help the agency create more accurate and timely forecasts, particularly for severe weather and extreme events, while also creating a path for new weather-observation technologies.

KBR has supported the CDP NMP for more than nine years. The program will be managed in Greenbelt, Maryland.

"We're driving expanded integration of commercial sensor and data sources into this platform and are honored to know our work helps forecasters give their communities earlier warnings and more time to prepare for dangerous weather,” May added in a release.

KBR’s Mission Technology Solutions business will be rebranded as Trinzic after its planned spin-off, the company announced last month. The spin-off is expected to close in January 2027.

Trinzic will work as an independent, publicly traded company focused on technology and engineering services for the space and national security sector. KBR will remain a separate publicly traded company that will focus on sustainable technology and services to support the energy transition.
