This week, world leaders are discussing climate change and the future of our planet at the United Nations Climate Change Conference, also known as COP26, but local leaders were also discussing much closer to home.

Greentown Labs hosted its Climatetech Summit on Thursday, November 4, at both its offices in Houston and Sommerville, Massachusetts. The hybrid event featured a full day of networking, panels, and thought leadership.

Missed the conversation? Here are five key moments from the event.

​"Houston cannot transition without transitioning its workforce, and we need to help with that and make sure that people understand that. Demystifying the jobs of the future is key."

— says Juliana Garaizar, Greentown Labs' head of Houston incubator and vice president of innovation, in her welcome address.

"The energy transition in Houston needs to happen in an equitable way," she says. "Houston is the most diverse city in the US. It is up to us now to make it the most inclusive."

"The world will continue to need a lot of hydrocarbons for quite a long period of time, and Houston can and should remain a leader there. But it will not be an engine for growth."

— says Bobby Tudor, former chair of the Greater Houston Partnership and chairman of Tudor, Pickering, Holt & Co, in his keynote.

"If we are not going to have that business, which accounts for approximately 40 percent of all jobs in Greater Houston, be an engine of growth, we sure as heck better find businesses that are, or we will not have the same kind of prosperity that we've had in our region," Tudor says.

"The Energy Capital of the World will be the leader in the global energy transition."

— says Mayor Sylvester Turner in his address.

"As a lifelong Houston, I am proud of our history and proud of the innovation, growth, and prosperity the energy industry brings to our community," he continues. "But, as leaders of the energy industry, I believe it is our responsibility to continue this legacy and develop the innovative technologies and practices needed to decarbonize the entire energy sector worldwide."

"Texas has more potential to produce clean energy — wind, solar, storage — and efficiency than any other state."

says HARC President + CEO John Hall in his address.

"And we're fortunate that today — even though we continue to lead the country in producing oil and gas — 40 percent of the electricity being used in this state is zero emitting."

"You don't get change by wishing and hoping. You need to plan and to act."

says Quantum New Energy CEO Patricia Vega on the panel about transitioning the workforce.

"We live in a world where we can track steps, calories, and likes on social media, but if I ask each one of you what is your carbon footprint or carbon efficiency, many of us don't know how to answer those questions and don't have the tools," she adds.

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.
