Thanks to recently announced funding, the power grid for the territory served by the Electric Reliability Council of Texas (ERCOT) will be connected to grids in other states.

Officials hope building a 320-mile transmission line that connects the ERCOT electric grid to electric grids in the Southeast will prevent power outages like the massive blackout that occurred in 2022 when a winter storm blasted Texas.

San Francisco-based Pattern Energy says its Southern Spirit project will cost more than $2.6 billion. Full-scale construction is supposed to get underway in 2028, and the project is set to go online in 2031.

The U.S. Department of Energy recently approved up to $360 million for the transmission project. The transmission line will stretch from Texas’ border with Louisiana to Mississippi. It’ll supply about 3,000 megawatts of electricity in either direction. That’s enough power for about 750,000 residential customers during ERCOT’s peak hours.

ERCOT’s more than 54,100 miles of transmission lines supply power to about 90 percent of Texans.

“The U.S. transmission network is the backbone of our nation’s electricity system. Though our grid has served U.S. energy needs for more than a century, our country’s needs are changing,” David Turk, under secretary at the Department of Energy, says in a news release.

“DOE’s approach to deploying near-term solutions and developing long-term planning tools will ensure our electric grid is more interconnected and resilient than ever before,” Turk adds, “while also supporting greater electricity demand.”

The other three projects that recently received funding from the DOE include:

  • Aroostook Renewable Project, which will construct a new substation in Haynesville, Maine, and a 111-mile transmission line connecting to a substation in Pittsfield, Maine.
  • Cimarron Link, a 400-mile HVDC transmission line from Texas County, Oklahoma to Tulsa, Oklahoma
  • Southline, which will construct a 108-mile transmission line between Hidalgo County, New Mexico, and Las Cruces, New Mexico. The DOE previously supported a 175-mile line from Hidalgo County, New Mexico, to Pima County, Arizona, in Southline Phase 1 on the first round of the Transmission Facilitation Program.

This month's funding completes the $2.5 billion in awards from the Transmission Facilitation Program which is administered through the Building a Better Grid Initiative that launched in January 2022. Its mission has been to develop nationally significant transmission lines, increase resilience by connecting regions of the country and improve access to clean energy sources, according to the DOE.

Earlier this year, ERCOT, which manages 90 percent of Texas’ power supply, forecasted a major spike in demand for electricity over the next five to seven years

Meta taps Houston geothermal co. to power data center growth with clean energy

big tech

A Houston company has signed a new agreement with Meta Platforms Inc. — Facebook's parent company — to power the tech giant's data center growth.

Houston-based Sage Geosystems agreed to deliver up to 150 megawatts of new geothermal baseload power to Meta. The companies made the announcement this week at the United States Department Energy’s Catalyzing Next Generation Geothermal Development Workshop.

The deal is significant because it's the first next-generation geothermal project located to the east of the Rocky Mountains, the companies report in a news release.

“This announcement is the perfect example of how the public and private sector can work together to make the clean energy transition a reality,” Cindy Taff, CEO of Sage Geosystems, says in the release. “We are thrilled to be at the forefront of the next generation of geothermal technology and applaud the DOE for supporting the commercialization of innovation solutions.

"As energy demand continues to grow, the need for reliable, resilient and sustainable power is paramount and our partnership with Meta underscores the critical need for innovative and sustainable energy solutions like ours,” she continues.

The project's first phase will aim to be operating in 2027. The plans reflect how geothermal is being recognized as a growing carbon-free energy source in the country, and how Meta is committed to clean energy initiatives.

“The U.S. has seen unprecedented growth in demand for energy as our economy grows, the manufacturing sector booms thanks to the Biden-Harris Administration’s Investing in America agenda, and new industries like AI expand,” U.S. Energy Deputy Secretary David Turk says. “The Administration views this increased demand as a huge opportunity to add more clean, firm power to the grid and geothermal energy is a game-changer as we work to grow our clean power supply.”

Sage's technology — called Geopressured Geothermal System — works deep in the earth to develop energy storage and geothermal baseload power.

“Meta thanks the Department of Energy’s leadership on promoting and supporting the exploration of new energy sources like geothermal," Urvi Parekh, head of renewable energy at Meta, says. "That leadership supports Meta’s goal to enable the addition of reliable, affordable, and carbon-free power to the grid with this geothermal energy deal. We are excited to partner with such an innovative company like Sage Geosystems that is a proven leader in geothermal development on this project and beyond.”

Sage recently teamed up with a utility provider for an energy storage facility in the San Antonio metro area to build its three-megawatt EarthStore facility.

The company is also working on an exploratory geothermal project for the Army’s Fort Bliss post in Texas, which is the third U.S. Department of Defense geothermal initiative in the Lone Star State.

Houston researchers develop heating method to recover critical minerals from e-waste

hot new research

Researchers at Rice University have developed a new technique to efficiently recycle electronic waste and harvest critical minerals using rapid heating.

Most electronic devices use flame-retardant plastic. The plastic is formulated from a critical metal called antimony.

However, recapturing antimony is typically a challenging task since it first has to be released from the plastic. As it is released, other compounds can form, such as organic bromides, which are toxic and difficult to capture. However, the organic bromides can also be reused and have applications in industrial chemicals when safely captured.

“Conventionally heating the plastic releases the antimony in a volatile and difficult-to-collect form as well as creating and releasing hazardous organic bromide compounds,” Leo Haoxin Ye, first author of the paper and a graduate student at Rice, said in a news release. “Other options are risky or more impractical, such as using strong acids, organic solvents or multistep treatment options.”

To address this issue, leading Rice chemistry professor James Tour, Ye and their team adapted Tour’s flash Joule heating technique, which heats materials to hundreds of degrees Celsius in milliseconds, according to Rice.

The team ground up flame-retardant plastic waste and placed it between two sheets of electrically heated carbon paper before using what’s known as isothermal-clamped flash Joule heating to release and collect the antimony.

The team found that limiting the time the plastic spent in the high temperature range dramatically reduced the production of the hazardous organic bromide compounds. The plastic remained between 200 degrees and 500 degrees Celsius for only 9.4 milliseconds, according to Rice.

Through the process, the team recovered 90 percent of antimony from tested materials and converted 83 percent of the bromide into hydrogen bromide. Their findings were published this month in the journal Nature Chemical Engineering.

“Isothermal-clamped flash Joule heating could improve the speed, safety and practicality of antimony recovery from discarded flame-retardant plastics,” Tour added in the release. “This represents an important step forward to conserving and reusing our critical antimony supply while also regenerating bromide salts for reuse.”

The study noted that the world is currently trending toward producing 82 million metric tons of flame-retardant plastic waste by 2030, which adds to the fact that e-waste is the fastest-growing solid waste stream in the world.

The research was funded by the Air Force Office of Scientific Research and the U.S. Army Corps of Engineers.

Tesla unveils new Roadster sports car, which can thrust itself in the air

Tesla Talk

Tesla has unveiled its new Roadster sports car, which can thrust itself in the air, among other engineering bells and whistles. But drivers shouldn't expect to take it for a spin anytime soon.

Elon Musk's electric car company rolled out its second-generation Roadster at a Thursday event, showing off a set of cold gas thrusters and a “multi-mode” suction system that can fling the car in the air for short spurts and spin the vehicle mid-flight.

“Turns out the future does have flying cars,” Musk, Tesla's CEO, wrote on his social media platform X shortly after.

That future could be a ways off, however, given the regulatory hurdles for flying vehicles and the tangle of state rules that still need to be met.

“I’m not sure every state is going to allow a driver in the middle of traffic to suddenly elevate himself and fly," said David Vladeck, a Georgetown Law professor and former director of the FTC’s Bureau of Consumer Protection. “There is going to be a long process to let anything like that on a road.”

Thursday's event was hosted at the Texas rocket testing and development center for SpaceX — Musk's publicly-traded rocket company — and Tesla's executives noted that they “borrowed” some SpaceX technology to get the new Roadster in the air. Beyond quick jumps and flips, Tesla also said the car can accelerate from zero to 60 miles (96.6 km) an hour in less than a second.

This launch arrived after years of delays and anticipation around the new Roadster — and Tesla shares climbed in morning trading on Friday before falling amid a sell-off in companies tied to artificial intelligence.

The wait isn't completely over. Musk said production for consumers won't begin until 2028. Tesla also didn't immediately set a price tag on its latest EV.

Tesla was taking reservations for Roadster “rocket” car purchases on its website Friday morning, though the fine print said there was no guarantee when the vehicle would be delivered — or whether it would be delivered at all.

Bryant Walker Smith, former vice chair of a Department of Transportation advisory group on innovation, was unimpressed — though he did note Musk's ability to keep Tesla's stock high.

“This was a demonstration of a one-off car using a technology around for many years and will not be coming to public roads in 2028," said Smith, a law professor at the University of South Carolina. “Tesla pretty uniquely has been able to sell itself on a future that is an order of magnitude greater than reality.”

Musk has repeatedly said that the future of driving will be autonomous — and Austin-based Tesla has focused much of its business on building out self-driving features for its vehicles and, more recently, launching its own (still limited) robotaxi business.

But the company maintains that the Roadster will be made to have humans behind the wheel, calling the EV the “best of the last human-driven cars.”

Thursday's demo was technically autonomous “to make sure we don’t kill anyone,” Musk noted. But long-term, he said, the new Roadster will be “the only manually driven car that Tesla makes.”

“This is not necessarily a safety-optimized car,” Musk later added, met by laughter from the audience. But “it takes the fun meter to 11 out of 10.”

Tesla's first Roadster was launched back in 2008. And in 2018, Musk went as far as placing one on a rocket — with a mannequin dubbed “Starman” in the driver's seat — and launching it into space.

Again, the second-generation Roadster isn't immediately hitting the market. And whether the ambitious new vehicle boosts the company's bottom line remains to be seen.

In second-quarter earnings reported over the summer, Tesla's profits fell as the company spent more on research and development for its robotaxi and robotics businesses — which cut into money made from an otherwise sharp increase in vehicle sales. Net income totaled $1.11 billion for the period, while revenue climbed to $28.24 billion.

TEX-E names New Climate Ventures as latest expert in residence

energy mentors

Texas Exchange for Energy & Climate Entrepreneurship (TEX-E) has named its latest expert in residence.

The Houston-based energy transition nonprofit recently announced that New Climate Ventures will join the newly established program. The Expert-in-Residence partnership aims to connect TEX-E Fellows with "the people and organizations shaping the future of energy and entrepreneurship," the nonprofit previously announced.

Taylor Chapman, an investment principal at New Climate Ventures, sits on TEX-E's board of directors. New Climate Ventures invests in early-stage startups building next-gen technologies in the energy, materials and fuels sectors. The venture capital firm's portfolio includes Houston-based clean energy startups like Solidec, Syzygy Plasmonics and Rheom Materials.

“If you know me, you know that I'm passionate about ensuring that my beloved hometown, Houston, is the energy capital of the future — not just of the past," Chapman said in a LinkedIn post. "TEX-E is building a key piece to ensure that's the case: a strong pipeline of graduate and college students immersed [and] versed in the world of energy [and] climate entrepreneurship."

TEX-E says the partnership with New Climate Ventures will allow its fellows opportunities to learn from investors that work with emerging companies and understand how they evaluate new technologies.

TEX-E announced Houston-based geothermal unicorn Fervo Energy and venture capital firm Mercury Fund as its first experts in residence in August. At the time, it said the partnerships would allow its fellows to network and work with Tim Latimer, CEO of Fervo; Sarah Jewett, COO of Fervo; and Blair Garrou, managing partner of Mercury Fund.

The nonprofit was founded in 2022 through partnerships with MIT Martin Trust Center for Entrepreneurship and Greentown Labs. It works with university students from six schools: Rice University, University of Houston, Prairie View A&M University, The University of Texas at Austin, Texas A&M University and MIT.
