Texas LNG, a four million tonnes per annum liquefied natural gas export terminal to be constructed in the Port of Brownsville, and a subsidiary of Glenfarne Energy Transition, announced the selection of its new partner.

Gulf LNG Tugs of Texas will operate, build, and deliver tugboats under an agreement to assist LNG carriers arriving at the facility. Tugs of Texas is part of a consortium of Suderman & Young Towing Co., Bay-Houston Towing, and Moran Towing Corp., and the tugboats will be among the “most modern, low-emissions tugboats available to serve a facility of Texas LNG’s size” according to the company. This will also align with Texas LNG’s "Green by Design" approach, and the deal is a long-term agreement.

The projected port for Texas LNG is considered to be an area with consistent operating temperatures, and reliable maritime operations with lower probability of impact from inclement weather like storms and damage associated with them. Globally, Texas LNG is also designed to be one of the lowest-emitting export terminals. Texas LNG is developing the project site on the north shore of the Port of Brownsville. This area offers access to a deep-water ship channel in close proximity to the Gulf of Mexico and the Panama Canal.

“Gulf LNG Tugs is excited to be providing marine services in a long-term partnership with Texas LNG,” the companies say in a joint statement. “We are proud to be the exclusive tug operator for LNG vessels to yet another successful LNG project in the Port of Brownsville and look forward to expanding our operations in the port and our presence in the Rio Grande Valley community."

New York and Houston-based Glenfarne works to provide solutions to lower the world’s carbon footprint, which aligns with the common goals of all the companies involved.

“The Texas LNG team undertook a comprehensive process to identify a marine service provider that not only matches our commitment to environmental stewardship, but also provides our customers with reliable, cost-effective marine services,” Brendan Duval, CEO and Founder of Glenfarne Energy Transition said in a news release. “We are pleased to have Gulf LNG Tugs on board as a partner and look forward to the jobs and local content they will bring to both Texas LNG and the local Rio Grande Valley community."

Texas LNG recently announced that it signed a Heads of Agreement with EQT Corporation for natural gas liquefaction services for 0.5 MTPA of LNG, in addition to partnerships with Baker Hughes and ABB to help develop the terminal. This represents equipment selections for Texas LNG to date that is worth half a billion dollars’ worth.

Construction is slated to begin this year after the financing of the project is finalized.

  • Houston-based Torres Orbital Mining (TOM),which develops autonomous excavation systems for extreme environments on Earth and the moon, enabling safe, data-driven resource recovery and laying the groundwork for sustainable off-world industry.

Other startups from around the world joined the Houston incubator in the same time period, including:

More than 100 startups joined Greentown this year, according to an end-of-year reflection shared by Greentown CEO Georgina Campbell Flatter.

Flatter joined Greentown in the top leadership role in February 2025. She succeeded former CEO and president Kevin Knobloch, who stepped down in July 2024.

"I moved back to the United States in March 2025 after six years overseas—2,000 miles, three children, and one very patient husband later. Over these months, I’ve had the chance to hear from the entrepreneurs, industry leaders, investors, and partners who make this community thrive. What I’ve experienced has left me brimming with urgent optimism for the future we’re building together," she said in the release.

According to Flatter, Greentown alumni raised more than $2 billion this year and created more than 3,000 jobs.

"Greentown startups and ecosystem leaders—from Boston, Houston, and beyond—are showing that we can move further and faster together. That we don’t have to choose between more energy or lower emissions, or between increasing sustainability and boosting profit. I call this the power of 'and,'" Flatter added. "We’re working for energy and climate, innovation and scale, legacy industry and startups, prosperity for people and planet. The 'and' is where possibility expands."

NRG makes latest partnership to grow virtual power plant

VPP partners

Houston-based NRG Energy recently announced a new long-term partnership with San Francisco-based Sunrun that aims to meet Texas’ surging energy demands and accelerate the adoption of home battery storage in Texas. The partnership also aligns with NRG’s goal of developing a 1-gigawatt virtual power plant by connecting thousands of decentralized energy sources by 2035.

Through the partnership, the companies will offer Texas residents home energy solutions that pair Sunrun’s solar-plus-storage systems with optimized rate plans and smart battery programming through Reliant, NRG’s retail electricity provider. As new customers enroll, their stored energy can be aggregated and dispatched to the ERCOT grid, according to a news release.

Additionally, Sunrun and NRG will work to create customer plans that aggregate and dispatch distributed power and provide electricity to Texas’ grid during peak periods.

“Texas is growing fast, and our electricity supply must keep pace,” Brad Bentley, executive vice president and president of NRG Consumer, said in the release. “By teaming up with Sunrun, we’re unlocking a new source of dispatchable, flexible energy while giving customers the opportunity to unlock value from their homes and contribute to a more resilient grid

Participating Reliant customers will be paid for sharing their stored solar energy through the partnership. Sunrun will be compensated for aggregating the stored capacity.

“This partnership demonstrates the scale and strength of Sunrun’s storage and solar distributed power plant assets,” Sunrun CEO Mary Powell added in the release. “We are delivering critical energy infrastructure that gives Texas families affordable, resilient power and builds a reliable, flexible power plant for the grid.”

In December, Reliant also teamed up with San Francisco tech company GoodLeap to bolster residential battery participation and accelerate the growth of NRG’s virtual power plant network in Texas.

In 2024, NRG partnered with California-based Renew Home to distribute hundreds of thousands of VPP-enabled smart thermostats by 2035 to help households manage and lower their energy costs. At the time, the company reported that its 1-gigawatt VPP would be able to provide energy to 200,000 homes during peak demand.
