A Houston-based coalition that launched this month aims to educate Texas officials about technology designed to shore up the state’s power grid.

The public-private Texas Reliability Coalition says it will promote utility-scale microgrid technology geared toward strengthening the resilience and reliability of the Texas power grid, particularly during extreme weather.

A utility-operated microgrid is a group of interconnected power loads and distributed energy sources that can operate in tandem with or apart from regular power grids, such as the grid run by the Electric Reliability Council of Texas (ERCOT). Legislation passed in 2023 enables the use of utility-scale microgrid technology in Texas’ deregulated energy market, according to the coalition.

John Elder, executive director of the coalition, says that with the legal framework now in place, the Public Utility Commission of Texas and ERCOT need to create rules to establish the Texas marketplace for microgrid technology. The goal, he says, is to “take the Texas grid from good to great” by installing microgrid technology, improving the infrastructure, and strengthening the system — all targeted toward meeting power needs during extreme weather and amid growing demand.

Houston-based CenterPoint Energy will test the utility-scale microgrid technology being promoted by the coalition. In a January 31 filing with the Public Utility Commission, CenterPoint says microgrid technology will be featured in a $36.5 million pilot program that’ll set up an estimated three to five microgrids in the company’s service area. The pilot program is slated to last from 2026 to 2028.

In the public affairs arena, five Houston executives are leading the new reliability commission’s microgrid initiative.

Elder, one of the coalition’s founding members, is president and CEO of Houston-based Acclaim Energy. Other founders include Ember Real Estate Investment & Development, Park Eight Development, and PowerSecure. Ember and Park Eight are based in Houston. Durham, North Carolina-based PowerSecure, which produces microgrid technology, is a subsidiary of energy provider Southern Co.

Aside from Elder, members of the coalition’s board are:

  • Stewart Black, board secretary of the coalition and vice president of Acclaim Energy’s midstream division
  • Todd Burrer, president of municipal utility districts at Inframark.
  • Harry Masterson, managing principal of Ember
  • Martin Narendorf, former vice president at CenterPoint Energy.

California co. announces fully sustainable, hydrogen-powered data center in Houston

moving in

The Houston area will soon be home to what's being lauded as the first fully sustainable 1-gigawatt data center on a 600-acres site east of Houston.

Data center-as-a-service company ECL, headquartered in Mountain View, California, announced its plans to build the ECL TerraSite-TX1. Hardware and cloud service company Lambda will serve as its first tenant. Lambda and other AI leaders will get access to necessary space and power for the next wave zero emission innovations.

Phase 1 of TerraSite-TX1 will be complete by summer of 2025 with a cost of approximately $450 million. The 50 megawatt of data center capacity will be utilized by data center cloud and AI cloud operators. The 1-gigawatt site will be constructed at a cost of approximately $8 billion. The funding will come from ECL and financial partners.

ECL Terrasite-TX1 comes at a needed time for Texas with The Electric Reliability Council of Texas stating on June 12 that the state’s power grid needs will grow approximately double by 2030. This is due in part to the growth of data centers and AI. The ECL Terrasite-TX1 is built to help eliminate the stress on the state’s power grid and help facilitate “state-level economic development and growth of the AI industry,” according to a news release.

ECL data centers are built to be modular, which allows for expansion in 1-megawatt increments. They are “ built to suit” and delivered in less than 12 months, which is shorter than the industry standard of 36 to 48.

“While others talk about delivering off-grid, hydrogen-powered data centers in five, ten, or 20 years, only ECL is giving the AI industry the space, power, and peace of mind they and their customers need, now,” Yuval Bachar, co-founder and CEO of ECL, says in a news release. “The level of innovation that we have introduced to the market is unprecedented and will serve not only us and our customers but the entire data center industry for decades to come.”

ECL’s ECL-MV1 is the world’s first off-grid, hydrogen-powered modular data center that operates 24/7 with zero emissions, less noise, and a negative water footprint that replenishes water to the community. ECL-MV1 offers a 10x increase in “energy efficiency with a power usage effectiveness of 1.05 and a 7-times improvement in data density per rack, which is ideal for AI high-density demand” according to the release.

“The data center technology committed to by ECL is truly transformative in the industry,” Lambda's Vice President for Data Center Infrastructure Ken Patchett adds. “We believe ECL’s technology could unlock a powerful and eco-conscious foundation for AI advancement. This new infrastructure could give researchers and developers essential computational resources while drastically reducing the environmental impact of AI operations.”

Houston geothermal startup selects Texas location for first energy storage facility

major milestone

Houston-based geothermal energy startup Sage Geosystems has teamed up with a utility provider for an energy storage facility in the San Antonio metro area.

The three-megawatt EarthStore facility will be on land controlled by the San Miguel Electric Cooperative, which produces electricity for customers in 47 South Texas counties. The facility will be located in the town of Christine, near the cooperative’s coal-fired power plant.

Sage says its energy storage system will be paired with solar energy to supply power for the grid operated by the Electric Reliability Council of Texas (ERCOT). The facility is set to open later this year.

“Once operational, our EarthStore facility in Christine will be the first geothermal energy storage system to store potential energy deep in the earth and supply electrons to a power grid,” Cindy Taff, CEO of Sage Geosystems, says in a news release.

The facility is being designed to store geothermal energy during six- to 10-hour periods.

“Long-duration energy storage is crucial for the ERCOT utility grid, especially with the increasing integration of intermittent wind and solar power generation,” says Craig Courter, CEO of the San Miguel Electric Cooperative.

Texas launches new investigation into Houston's power utility following deadly outages after Beryl

zooming in

Texas' attorney general launched an investigation Monday into Houston's electric utility over allegations of fraud and waste following Hurricane Beryl, adding to the mounting scrutiny after widespread power outages left millions without electricity for days.

The latest investigation of CenterPoint Energy comes after state regulators and Republican Gov. Greg Abbott have also demanded answers about storm preparations and the response to Beryl, a Category 1 hurricane that knocked out power to nearly 3 million people around the nation’s fourth-largest city.

The storm was blamed for at least three dozen deaths, including those of some residents who died in homes that were left without air conditioning in sweltering heat after the storm's passage.

“My office is aware of concerning allegations regarding CenterPoint and how its conduct affected readiness during Hurricane Beryl,” Ken Paxton, the state's Republican attorney general, said in a statement. “If the investigation uncovers unlawful activity, that activity will be met with the full force of the law.”

The utility pledged its support of the investigation.

“We look forward to cooperating with the Texas Attorney General or any other agency and have made clear our commitment to upholding the values of our company,” CenterPoint spokesperson John Sousa said.

Paxton did not cite any specific allegations of waste or fraud in his announcement and his office did not respond to requests for comment.

Abbott has demanded answers from CenterPoint for what he called its slow restoration efforts and poor communication with customers in the days leading up to the storm. The state's Public Utility Commission has launched its own investigation, and lawmakers grilled the company’s top executive over its failures at a hearing last month.

CenterPoint has largely defended its storm preparedness and said that it deployed thousands of additional workers to help restore power. The utility provider has also begun a monthslong plan to replace hundreds of wooden utility poles and double its tree-trimming efforts after the governor pressed for swift action.

Beryl damaged power lines and uprooted trees when it made its Texas landfall on July 8. It’s the latest natural disaster to hit Houston after a powerful storm ripped through the area in May, leaving nearly 1 million people without power.

Many residents fear that chronic outages have become the norm after Texas’ power grid failed amid a deadly winter storm in 2021.

CenterPoint has previously faced questions over the reliability of Houston's power grid.

In 2008, Hurricane Ike, a Category 2 storm, knocked out power to more than 2 people million and it took 19 days to fully restore electricity. The city of Houston created a task force initiative to investigate the company's response and determined it needed to automate parts of its grid to minimize outages.

CenterPoint received millions of dollars in federal funding to implement this technology years ago. However, according to executive vice president Jason Ryan, it's still a work in progress.

Some utility experts and critics say the company hasn’t adapted its technology fast enough to meet the extreme weather conditions Texas will continue to face.

Houston renewable energy developer teams up with global commercial real estate biz

collaboration station

Houston-based Catalyze, a developer of independent power systems, has teamed up with commercial real estate services powerhouse Cushman & Wakefield to expand installation of solar panels and battery storage technology at U.S. commercial and industrial properties.

The two companies say the partnership will help owners and tenants of office buildings, warehouses, and other commercial properties reduce utility costs, boost operating income, achieve environmental goals and ease stress on the power grid.

“This partnership marks a significant step forward in our mission to accelerate the adoption of renewable energy among commercial and industrial customers, benefiting both tenants and building owners,” Jared Haines, CEO of Catalyze, says in a news release.

The partnership will enable Cushman & Wakefield to decrease greenhouse gas emissions at facilities it manages for clients as well as its own corporate offices. The real estate sector accounts for about 40 percent of greenhouse gas emissions around the world.

“Our strategic partnership with Catalyze is a testament to our shared commitment to decarbonize the built environment by being at the forefront of the clean energy revolution,” says Jessica Francisco, Cushman & Wakefield’s chief sustainability officer. “Together, we are poised to advance the adoption of solar and storage technologies while driving down costs for our clients.”

In May, Catalyze announced that it secured $100 million in financing from NY Green Bank to support a 79 megawatt portfolio of community distributed generation solar projects across the state of New York.

Houston entrepreneur launches new venture to shine light on sustainability

texas innovator

A Houston nuclear engineer and entrepreneur wants consumers to capture their own ray of sunlight to brighten the prospect of making clean energy a bigger part of the power grid.

Solar Slice Founder Nathan Childress says his new venture offers a fulfilling way to encourage and promote solar energy and a greener planet. An experienced entrepreneur, Childress also serves as founder and CEO of technology software company Macorva.

Although trained in nuclear power plant design, solar power drew his interest as a cheaper and more accessible alternative, and Childress tells InnovationMap that he thinks that the transition to cleaner energy, in Texas especially, needs to step up.

With energy demand skyrocketing, and the push toward renewable solutions, solar seems like a safe bet for Childress, a former competitive high-stakes poker player. Childress cites a recent Yale University study that says 63 percent of Americans “feel a personal responsibility to help reduce global warming.”

But some studies show that 80 to 90 percent of the money invested into fighting climate change “aren’t going to things that people actually consider helpful,” he says.

“They’re more just projects that sound good, that are not actually taking any action,” says Childress, who has called Houston home for 25 years. He received his doctorate in medical physics at M.D. Anderson Cancer Center, where he worked on software that provided radiation therapy for patients.

The initial Kickstarter fundraising round, which will be launched soon, will finance the construction of one utility-scale solar farm, on about five to 10 acres, which would produce about 1 megawatt, or 1,000 kilowatts, of clean energy. The plant would make enough energy to power about 200 average homes.

Childress says interest has been strong, with several thousand signed up on the Kickstarter launch list. Some who are signed up expressed interest in a subscription, he said, and that may be offered later. Initially, though, for a one-time purchase of $95, a Solar Slice client can purchase one virtual 50W slice of solar power, produced by the farm. Over its lifetime, Childress says, that one purchase can offset three tons of carbon dioxide.

The app tracks carbon offsetting, and energy production for the slice, showing a client “exactly how much I have helped the climate, here’s exactly how (many) emissions I have prevented from putting in the atmosphere,” he says.

The energy produced by five slices can offset the average American’s carbon footprint for a year, and the power generated by the solar farm will be sold to the electric grid. As clients purchase more slices, they can earn eco-credits to donate to other climate-friendly partners, to plant trees or create pollinator habitats.

While Solar Slice is a for-profit venture, contributors won’t get rich or even make money from their purchase. Rather, it provides validation.

“Our focus is maximizing the real world impact, not for financial gain. This is not something people sign up (for) to make money. We’re really clear about that,” Childress says. “I want to show that it’s possible to have a for-profit company that is sustainable, that does good work.

“And hopefully, we can be part of the spirit…for a bigger movement, and for consumers and business, especially, to do things that matter.”

The largest U.S. solar plants are in Nevada and California, and those states are sites under consideration, but Childress says Texas is the most likely home for the initial project. The ten largest utility-scale solar plants in Texas by capacity are all in far west or central parts of the state, according to the state comptroller’s office.

Childress has a team of four, who are handling the marketing, plant design and site scouting, and hopes to hire five to 10 more, depending on response and growth. He says the Solar Slice consumer can directly connect in real time to the contribution that their purchase will make toward a green energy future.

“That was our inspiration..let’s start something that is really making a difference..and making really clear to the individuals what’s being done,” he says.

Solar energy has become a growing source of power for Texas, comprising about 6 percent of the state’s energy generation, as of 2022, the comptroller’s office says.

The state ranks first in projected growth of solar energy over the next five years, with more than 9,500 operating solar plants, and many thousands more announced, according to the state Public Utility Commission.

“We would absolutely love to make this into something where we are building plants around the nation, around the world,” Childress he says.

However, resistance to alternative energy projects like solar and wind, especially on a large scale, remains in some quarters.

Obtaining site permits for swaths of land can be also a challenge. For example, a recent survey by Berkeley Lab of 123 professionals from 62 unique, large-scale wind and solar energy facilities showed that about one-third of wind and solar siting applications in the past five years were canceled.

Half of the projects experienced delays of six months or longer. And according to the survey, developers expect the trend to continue, and become more expensive to address.

However, another Berkeley Lab survey of residents who live within three miles of a solar power plant showed that most view the plant positively. The larger the plant, the more negative the response in the survey. The smaller the farm, the more positive the reactions.

Childress says many of the common objections to utility-scale solar farms are misguided, and incorrect. For example, the concern that they would take over available farmland or take up too much space.

He says that even if the entire U.S. power grid relied solely on solar power, the plants would occupy not even a half percent of available land, which is about one percent farmland.

Report: Texas solar power, battery storage helped stabilize grid in summer 2024, but challenges remain

by the numbers

Research from the Federal Reserve Bank of Dallas shows that solar power and battery storage capacity helped stabilize Texas’ electric grid last summer.

Between June 1 and Aug. 31, solar power met nearly 25 percent of midday electricity demand within the Electric Reliability Council of Texas (ERCOT) power grid. Rising solar and battery output in ERCOT assisted Texans during a summer of triple-digit heat and record load demands, but the report fears that the state’s power load will be “pushed to its limits” soon.

The report examined how the grid performed during more demanding hours. At peak times, between 11 a.m. and 2 p.m. in the summer of 2024, solar output averaged nearly 17,000 megawatts compared with 12,000 megawatts during those hours in the previous year. Between 6 p.m. and 9 p.m., discharge from battery facilities averaged 714 megawatts in 2024 after averaging 238 megawatts for those hours in 2023. Solar and battery output have continued to grow since then, according to the report.

“Batteries made a meaningful contribution to what those shoulder periods look like and how much scarcity we get into during these peak events,” ERCOT CEO Pablo Vegas said at a board of directors conference call.

Increases in capacity from solar and battery-storage power in 2024 also eclipsed those of 2023. In 2023 ECOT added 4,570 megawatts of solar, compared to adding nearly 9,700 megawatts in 2024. Growth in battery storage capacity also increased from about 1,500 megawatts added in 2023 to more than 4,000 megawatts added in 2024. Natural gas capacity also saw increases while wind capacity dropped by about 50 percent.

Texas’ installation of utility-scale solar surpassed California’s in the spring of last year, and jumped from 1,900 megawatts in 2019 to over 20,000 megawatts in 2024 with solar meeting about 50 percent of Texas' peak power demand during some days.

While the numbers are encouraging, the report states that there could be future challenges, as more generating capacity will be required due to data center construction and broader electrification trends. The development of generating more capacity will rely on multiple factors like price signals and market conditions that invite more baseload and dispatchable generating capacity, which includes longer-duration batteries, and investment in power purchase agreements and other power arrangements by large-scale consumers, according to the report.

Additionally, peak demand during winter freezes presents challenges not seen in the summer. For example, in colder months, peak electricity demand often occurs in the early morning before solar energy is available, and it predicts that current battery storage may be insufficient to meet the demand. The analysis indicated a 50% chance of rolling outages during a cold snap similar to December 2022 and an 80% chance if conditions mirror the February 2021 deep freeze at the grid’s current state.

The report also claimed that ERCOT’s energy-only market design and new incentive structures, such as the Texas Energy Fund, do not appear to be enough to meet the predicted future magnitude and speed of load growth.

Houston clean energy pioneer earns prestigious Welch Foundation award

Awards Season

A Rice University professor has earned a prestigious award from the Houston-based Welch Foundation, which supports chemistry research.

The foundation gave its 2025 Norman Hackerman Award in Chemical Research to Haotian Wang for his “exceptionally creative” research involving carbon dioxide electrochemistry. His research enables CO2 to be converted into valuable chemicals and fuels.

The award included $100,000 and a bronze sculpture.

“Dr. Wang’s extensive body of work and rigorous pursuit of efficient electrochemical solutions to practical problems set him apart as a top innovator among early-career researchers,” Catherine Murphy, chairwoman of the foundation’s Scientific Advisory Board, said in a news release.

Wang is an associate professor in the Department of Chemical and Biomolecular Engineering at Rice. The department’s Wang Group develops nanomaterials and electrolyzers for energy and environmental uses, such as energy storage, chemical and fuel generation, green synthesis and water treatment.

Wang also is co-founder of Solidec, a Houston startup that aims to turn his innovations into low-carbon fuels, carbon-negative hydrogen and carbon-neutral peroxide. The startup extracts molecules from water and air, then transforms them into pure chemicals and fuels that are free of carbon emissions.

Solidec has been selected for Chevron Technology Ventures’ catalyst program, a Rice One Small Step grant, a U.S. Department of Energy grant, and the first cohort of the Activate Houston program.

“Dr. Wang’s use of electrochemistry to close the carbon cycle and develop renewable sources of industrial chemicals directly intersects with the Welch Foundation mission of advancing chemistry while improving life,” Fred Brazelton, chairman and director of the Welch Foundation, said in the release.

Ramamoorthy Ramesh, executive vice president for research at Rice University, added: “We are proud to (Dr. Wang) at Rice. He’s using chemical engineering to solve a big problem for humanity, everything that the Welch Foundation stands for.”

Last year, the Hackerman Award went to Baylor College of Medicine's Livia Schiavinato Eberlin, who's known for her groundbreaking work in the application of mass spectrometry technologies, which are changing how physicians treat cancer and analyze tissues. Read more here.

Houston venture firm invests in Virginia fusion power plant company in collaboration with TAMU

fusion funding

Houston-based climate tech venture firm Ecosphere Ventures has partnered with Virginia Venture Partners and Virginia Innovation Partnership Corporation’s venture capital program to invest in Virginia-based NearStar Fusion Inc., which develops fusion energy power plants.

NearStar aims to use its proprietary plasma railgun technology to safely and affordably power baseload electricity on and off the power grid through a Magnetized Target Impact Fusion (MTIF) approach, according to a news release from the company.

NearStar’s power plants are designed to retrofit traditional fossil fuel power plants and are expected to serve heavy industry, data centers and military installations.

“Our design is well-suited to retrofit coal-burning power plants and reuse existing infrastructure such as balance of plant and grid connectivity, but I’m also excited about leveraging the existing workforce because you won’t need PhDs in plasma physics to work in our power plant,” Amit Singh, CEO of NearStar Fusion, said in a news release.

NearStar will also conduct experiments at the Texas A&M Hypervelocity Impact Laboratory (HVIL) in Bryan, Texas, on prototype fuel targets and evolving fuel capsule design. The company plans to publish the results of the experiments along with a concept paper this year. NearStar will work with The University of Alabama in Huntsville (UAH) to develop computer performance models for target implosions.

NearStar’s MTIF approach will utilize deuterium, which is a common isotope of hydrogen found in water. The process does not use tritium, which NearStar believes will save customers money.

“While avoiding tritium in our power plant design reduces scientific gain of the fusion process, we believe the vastly reduced system complexity and cost savings of eliminating complicated supply chains, regulatory oversight, and breeding of tritium allows NearStar to operate power plants more profitably and serve more customers worldwide, ”Douglas Witherspoon, NearStar founder and chief scientist, said in a news release.

Houston’s Ecosphere Ventures invests in climate tech and sustainability innovations from pre-seed to late-seed stages in the U.S. Ecosphere also supports first-time entrepreneurs and technical founders.
