In an electrifying sign for the renewables sector of Houston's energy industry, wind for the first time has essentially tied with coal as a power source for Texas homes and businesses.

In 2019, wind (19.97 percent) and coal (20.27 percent) were locked in a statistical dead heat to be the No. 2 energy source for customers of the Electric Reliability Council of Texas, or ERCOT. Natural gas ranked first (40.2 percent). The Austin-based nonprofit manages about 90 percent of the state's electrical grid.

Houston stands to benefit greatly from these winds of change.

Long dominant in the oil and gas industry as the Energy Capital of the World, Houston is adapting to the shifting tide from traditional energy sources to renewable energy sources like wind and solar. Over 30 companies involved in wind energy are based in the Houston area. Major local players in wind energy include BP Wind Energy North America Inc., EDP Renewables North America LLC, and Pattern Energy Group Inc. In addition, many of the state's more than 130 wind-generation projects are operated from Houston.

Bob Harvey, president and CEO of the Greater Houston Partnership, says the region's "unparalleled experience" with massive energy initiatives supplies an edge in the burgeoning renewable energy sector.

"Houston's talent base knows energy, from development to commercial operations, and the region offers a competitive advantage to renewable energy companies looking to develop projects both domestically and around the world," Harvey says. "Houston and Texas are well positioned as leaders who are developing large-scale renewable energy projects in both wind and solar."

Harvey says ERCOT's aggressive pursuit of wind and solar power also bodes well for Houston and the entire state.

"When combined with our natural advantages of great sites for wind and solar, our market structure has made Texas a global leader in the transition to low-carbon power generation," he says. "We expect Houston will continue to play a major role as wind, solar, and other renewable energy sources continue to rise on a global scale."

Susan Sloan, vice president of state affairs at the American Wind Energy Association, notes that Texas leads all states for wind energy, with 25 gigawatts of capacity generated by nearly 14,000 wind turbines. The Lone Star State produces about one-fourth of the country's wind power, and the wind energy industry employs more than 25,000 Texans.

With another 9 gigawatts of capacity coming online, "Texas continues to champion investment in wind energy as the state's electric load continues to increase," says Sloan, who's based in Austin. "Wind is an established and growing part of the Texas energy economy, and will be for years to come."

Texas has made great strides in wind energy in the past decade. In 2010, wind represented only 7.8 percent of ERCOT's power generation and ranked as the grid's No. 4 energy source, while coal stood at 39.5 percent and ranked first.

In September 2019, Norwegian energy research firm Rystad Energy predicted wind will bypass coal as a Texas energy source in 2020. Rystad Energy, which has an office in Houston, expects wind to generate 87 terawatt-hours of electricity in Texas this year compared with 84.4 terawatt-hours from coal. One terawatt-hour equals the output of 1 trillion watts over a one-hour period.

"Texas is just one of many red states that have recently 'gone green' by harnessing their great wind-generation potential," Carlos Torres-Diaz, head of gas market research at Rystad Energy, said in a release. Renewable energy sources like wind "are reaching a level where new installations are not driven solely by policies or subsidies, but by economics," he added.

Houston researchers make headway on affordable, sustainable sodium-ion battery

Energy Solutions

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”

FAA demands investigation into SpaceX's out-of-control Starship flight

Out of this world

The Federal Aviation Administration is demanding an accident investigation into the out-of-control Starship flight by SpaceX on May 27.

Tuesday's test flight from Texas lasted longer than the previous two failed demos of the world's biggest and most powerful rocket, which ended in flames over the Atlantic. The latest spacecraft made it halfway around the world to the Indian Ocean, but not before going into a spin and breaking apart.

The FAA said Friday that no injuries or public damage were reported.

The first-stage booster — recycled from an earlier flight — also burst apart while descending over the Gulf of Mexico. But that was the result of deliberately extreme testing approved by the FAA in advance.

All wreckage from both sections of the 403-foot (123-meter) rocket came down within the designated hazard zones, according to the FAA.

The FAA will oversee SpaceX's investigation, which is required before another Starship can launch.

CEO Elon Musk said he wants to pick up the pace of Starship test flights, with the ultimate goal of launching them to Mars. NASA needs Starship as the means of landing astronauts on the moon in the next few years.

TMC med-tech company closes $2.5M series A, plans expansion

fresh funding

Insight Surgery, a United Kingdom-based startup that specializes in surgical technology, has raised $2.5 million in a series A round led by New York City-based life sciences investor Nodenza Venture Partners. The company launched its U.S. business in 2023 with the opening of a cleanroom manufacturing facility at Houston’s Texas Medical Center.

The startup says the investment comes on the heels of the U.S. Food and Drug Administration (FDA) granting clearance to the company’s surgical guides for orthopedic surgery. Insight says the fresh capital will support its U.S. expansion, including one new manufacturing facility at an East Coast hospital and another at a West Coast hospital.

Insight says the investment “will provide surgeons with rapid access to sophisticated tools that improve patient outcomes, reduce risk, and expedite recovery.”

Insight’s proprietary digital platform, EmbedMed, digitizes the surgical planning process and allows the rapid design and manufacturing of patient-specific guides for orthopedic surgery.

“Our mission is to make advanced surgical planning tools accessible and scalable across the U.S. healthcare system,” Insight CEO Henry Pinchbeck said in a news release. “This investment allows us to accelerate our plan to enable every orthopedic surgeon in the U.S. to have easy access to personalized surgical devices within surgically meaningful timelines.”

Ross Morton, managing Partner at Nodenza, says Insight’s “disruptive” technology may enable the company to become “the leader in the personalized surgery market.”

The startup recently entered a strategic partnership with Ricoh USA, a provider of information management and digital services for businesses. It also has forged partnerships with the Hospital for Special Surgery in New York City, University of Chicago Medicine, University of Florida Health and UAB Medicine in Birmingham, Alabama.
