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.

Harris County looks to future with new Climate Justice Plan

progress plan

Harris County commissioners approved a five-point Climate Justice Plan last month with a 3-1 vote by Harris County commissioners. The plan was created by the Office of County Administration’s Office of Sustainability and the nonprofit Coalition for Environment, Equity and Resilience.

“Climate action planning that centers on justice has the potential to spark innovative thinking and transformative actions that will lead to meaningful and just transitions in communities, policies, funding mechanisms, and implementation strategies,” the 59-page report reads.

The plan seeks to address issues relating to ecology, infrastructure, economy, community and culture. Here’s a breakdown:

Ecology

The plan will work towards clean air, water, and soil efforts that support the health of the environment, renewable energy that reduces greenhouse gases and pollution, and conservation and protection of our natural resources. Some action items include:

  • Increasing resources for local government agencies
  • Developing a free native seed bank at all libraries
  • Identifying partners and funding streams to reduce the costs of solar power for area households
  • Producing renewable energy on large tracts of land
  • Expanding tree planting by 20 percent
  • Providing tree maintenance and restoration efforts
  • Incentivizing gray water systems and filtration to conserve fresh water

Economy

In terms of the economy, the Climate Justice Plan wants the basic needs of the community met and wants to also incentivize resilience, sustainability, and climate solutions, and recycling and reuse methods. Specific actions include:

  • Quantifying the rising costs associated with climate change
  • Expanding resources and partnering with organizations to support programs that provide food, utility, housing, and direct cash assistance
  • Supporting a coalition of area non-profit organizations and county offices to strengthen social service support infrastructure
  • Supporting home repair, solar installation, and weatherization programs
  • Identify methods to expand free and efficient recycling and composting services
  • Creating a climate tax levied on greenhouse gas emissions to develop a climate fund to offset the impacts of pollution

Infrastructure

As Houston has been prone to hurricanes and flooding damage, the infrastructure portion of the plan aims to protect the region from risks through preventative floodplain and watershed management. Highlights include:

  • Investing in generators and solar power, plus battery backup and bidirectional EV charging for all county libraries
  • Providing more heating and cooling centers with charging stations
  • Coordinating and deploying community microgrids, especially in neighborhoods prone to losing power
  • Seeking partnerships and funding for low- or no-cost water purifiers for areas with the highest needs
  • Protecting the electric grid through regular maintenance and upgrading, and advocating for greater accountability and responsiveness among appointed officials
  • Developing regulations to require resilient power line infrastructure to prevent outages and failures in new developments

Community and Culture

Housing, a strong economy and access to affordable and healthy food will be achieved under the community aspect of the plan. Under culture, the plan seeks to share knowledge and build trust. Key goals include:

  • Developing a campaign to promote the use of the Harris County 311 system to identify critical community concerns
  • Supporting the development of a Community Housing Plan that ensures stable and safe housing
  • Advocating for revisions to Federal Emergency Management Agency (FEMA) disaster funding to account for renters’ losses and unmet housing needs
  • Developing and funding a whole-home program for repairs, weatherization, and solar energy
  • Developing culturally relevant public relations campaigns to increase knowledge of health, environment and biodiversity across generations

Houston company completes orphan well decommission project in the Gulf

temporary abandonment

Houston-based Promethean Energy announced this month that it has successfully decommissioned offshore orphaned wells in the Matagorda Island lease area.

Around this time last year, the company shared that it would work on the temporary abandonment of nine orphan wells on behalf of the Department of Interior's Bureau of Safety and Environmental Enforcement, or BSEE, in the area. Promethean is known for decommissioning mature assets in a cost-effective and environmentally sustainable manner.

“Our team is incredibly proud to have completed this critical work efficiently, safely, and ahead of budget,” Steve Louis, SVP of decommissioning at Promethean Energy, said in a news release. “By integrating our expertise, technologies and strategic partnerships, we have demonstrated that decommissioning can be both cost-effective and environmentally responsible.”

The company plans to use the Matagora Island project as a replicable model to guide similar projects worldwide. The project used comprehensive drone inspections, visual intelligence tools for safety preparations and detailed well diagnostics to plug the wells.

Next up, Promethean is looking to decommission more of the estimated 14,000 unplugged wells in the Gulf.

"Building on our strong execution performance, our strategy is to continue identifying synergies with other asset owners, fostering collaboration, and developing sustainable decommissioning campaigns that drive efficiency across the industry," Ernest Hui, chief strategy officer of Promethean Energy, added in the release.

Oxy opens energy-focused innovation center in Midtown Houston

moving in

Houston-based Occidental officially opened its new Oxy Innovation Center with a ribbon cutting at the Ion last month.

The opening reflects Oxy and the Ion's "shared commitment to advancing technology and accelerating a lower-carbon future," according to an announcement from the Ion.

Oxy, which was named a corporate partner of the Ion in 2023, now has nearly 6,500 square feet on the fourth floor of the Ion. Rice University and the Rice Real Estate Company announced the lease of the additional space last year, along with agreements with Fathom Fund and Activate.

At the time, the leases brought the Ion's occupancy up to 90 percent.

Additionally, New York-based Industrious plans to launch its coworking space at the Ion on May 8. The company was tapped as the new operator of the Ion’s 86,000-square-foot coworking space in Midtown in January.

Dallas-based Common Desk previously operated the space, which was expanded by 50 percent in 2023 to 86,000 square feet.

CBRE agreed to acquire Industrious in a deal valued at $400 million earlier this year. Industrious also operates another local coworking space is at 1301 McKinney St.

Industrious will host a launch party celebrating the new location Thursday, May 8. Find more information here.
