A Northern California-born energy storage startup has established its headquarters in The Woodlands.

Plus Power, which develops battery systems designed to store backup power for electric grids, recently signed a lease for nearly 7,000 square feet at Three Hughes Landing in The Woodlands. The company previously was based in coworking space at the Rayford Office Park in Spring.

The company, founded in 2018, shifted its headquarters from San Francisco to the Houston area last year.

“We chose The Woodlands for its beauty, and walkable access to great nearby hotels, restaurants, and healthy groceries,” says Brandon Keefe, CEO of Plus Power. “A Houston base reflects our deep focus on the Texas market, as we are investing nearly $1 billion in several projects here that will be online by the first quarter of 2024, with more in [the works] behind that.”

About 40 employees work from Plus Power’s new office in The Woodlands. Across North America, the company employs about 130 people, including several in Austin. As of July 10, the startup listed nine job openings.

Plus Power develops, owns, and operates utility-scale systems that store energy in huge lithium-ion batteries during low-demand periods. In times of peak demand, power providers can tap into this stored energy.

“Standalone energy storage is rapidly transforming the U.S. energy markets, because it is cheaper than new natural gas plants, faster to build than fossil peakers or transmission, and able to perform diverse energy services,” the company explains in its job postings.

Peakers are backup power plants that run on fossil fuels.

One of Plus Power’s storage facilities is the 100-megawatt Gambit project, which opened two years ago in Angleton. The nearly eight-acre facility supports power supplies for the Electric Reliability Council of Texas (ERCOT), which runs the power grid for 90 percent of Texas.

The company says the Angleton facility has fed backup energy to ERCOT during this year’s and last year’s heatwaves, as well as last December’s winter freeze.

The Gambit facility might ring a bell with some folks in the Houston area. In January 2022, Austin-based automaker Tesla unveiled a backup power storage facility in Angleton. Plus Power bought the project from Tesla in June 2022.

Plus Power’s development pipeline contains 10 gigawatts’ worth of energy storage projects in 28 states and Canada. That includes massive projects on tap for Hawaii and Arizona.

Last November, Plus Power announced it had secured $219 million in debt financing for construction of the 185-megawatt Kapolei project on a roughly eight-acre site in Oahu, Hawaii. The facility will be tied to Hawaiian Electric’s power grid. Mizuho Securities USA and KeyBank led the financing.

This April, Plus Power held a groundbreaking ceremony for the Sierra Estrella project in Tolleson, a Phoenix suburb. The 250-megawatt system will serve Salt River Project (SRP), a utility provider in the Phoenix area. The roughly 11-acre Tolleson facility is set to open next year, as is another Plus Power project for SRP — the 90-megawatt Superstition facility in Gilbert, another Phoenix suburb.

As its development pipeline demonstrates, Plus Power is firmly plugged into the fast-growing energy storage market.

According to the Houston-based energy research and consulting firm Wood Mackenzie and the American Clean Power Association, the U.S. energy storage market installed a record-breaking 4.8 gigawatts of capacity in 2022. This year, that number is projected to approach 75 gigawatts.

In a March 2023 news release, John Hensley, the clean power group’s vice president of research and analytics, says the U.S. market “is on a rapid growth curve and is already a key component of building a resilient grid that supports abundant clean energy.”

Gold H2 harvests clean hydrogen from depleted California reservoirs in first field trial

breakthrough trial

Houston climatech company Gold H2 completed its first field trial that demonstrates subsurface bio-stimulated hydrogen production, which leverages microbiology and existing infrastructure to produce clean hydrogen.

Gold H2 is a spinoff of another Houston biotech company, Cemvita.

“When we compare our tech to the rest of the stack, I think we blow the competition out of the water," Prabhdeep Singh Sekhon, CEO of Gold H2 Sekhon previously told Energy Capital.

The project represented the first-of-its-kind application of Gold H2’s proprietary biotechnology, which generates hydrogen from depleted oil reservoirs, eliminating the need for new drilling, electrolysis or energy-intensive surface facilities. The Woodlands-based ChampionX LLC served as the oilfield services provider, and the trial was conducted in an oilfield in California’s San Joaquin Basin.

According to the company, Gold H2’s technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

“This field trial is tangible proof. We’ve taken a climate liability and turned it into a scalable, low-cost hydrogen solution,” Sekhon said in a news release. “It’s a new blueprint for decarbonization, built for speed, affordability, and global impact.”

Highlights of the trial include:

  • First-ever demonstration of biologically stimulated hydrogen generation at commercial field scale with unprecedented results of 40 percent H2 in the gas stream.
  • Demonstrated how end-of-life oilfield liabilities can be repurposed into hydrogen-producing assets.
  • The trial achieved 400,000 ppm of hydrogen in produced gases, which, according to the company,y is an “unprecedented concentration for a huff-and-puff style operation and a strong indicator of just how robust the process can perform under real-world conditions.”
  • The field trial marked readiness for commercial deployment with targeted hydrogen production costs below $0.50/kg.

“This breakthrough isn’t just a step forward, it’s a leap toward climate impact at scale,” Jillian Evanko, CEO and president at Chart Industries Inc., Gold H2 investor and advisor, added in the release. “By turning depleted oil fields into clean hydrogen generators, Gold H2 has provided a roadmap to produce low-cost, low-carbon energy using the very infrastructure that powered the last century. This changes the game for how the world can decarbonize heavy industry, power grids, and economies, faster and more affordably than we ever thought possible.”

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.
