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.

Houston-based Artemis, formerly Monalee, has closed its latest funding round. Rendering courtesy Artemis.

Houston tech startup Artemis has raised $6 million from 10 investors. The company offers an AI-supported platform that enables solar, battery storage and home improvement contractors to design, sell and finance energy projects.

Long Journey and Copec WIND Ventures co-led the round, with participation from angel investor Scott Banister, Coalition Operators, FJ Labs, Ludlow Ventures, Palm Tree Crew, Plug and Play Ventures, Shrug Capital and Tribeca Ventures.

To help propel growth, the company secured $10 million in financing last year (under its previous name, Monalee) from venture debt and growth credit provider Applied Real Intelligence. As Monalee, the company raised $16 million in venture capital.

The company was founded in 2022 as an installer of solar and battery storage projects. Five years later, the startup used in-house technology to establish its standalone software platform as it began pivoting away from installation. The company recently adopted the Artemis brand name.

Artemis says its platform saves time and money for installers of residential solar, battery storage, and energy projects. The platform combines an AI-powered design tool with embedded financing capabilities and compliance automation to create a single operating system.

The company says its customers report as much as a 72 percent reduction in software costs and up to 98 percent faster turnaround times. Thus far, more than 100 installers are using Artemis’ technology.

“Installers shouldn’t need six tools and a week of back-and-forth to sell a project," Walid Halty, co-founder and CEO of Artemis, said in a press release. “This funding gives us the fuel to scale our mission to compress design, financing, and compliance into a single flow so every installer can operate like a modern energy company. We’re not just speeding up deals, we're modernizing how distributed energy gets built.”

The Artemis platform, now available in the U.S. and soon to be launched in Latin America, caters to home improvement contractors, solar companies, lenders, and utilities.

“Artemis is transforming the complexity of distributed energy into elegant simplicity," added Arielle Zuckerberg, general partner at Long Journey.
