Transition News

Houston and Boston climate tech incubator Greentown Labs has named Georgina Campbell Flatter as the organization’s incoming CEO.

Flatter will transition to Greentown from her role as co-founder and executive director of TomorrowNow.org, a global nonprofit that studies and connects next-generation weather and climate technologies with communities most affected by climate change.

“We are at a transformational moment in the energy transition, with an unprecedented opportunity to drive solutions in energy production, sustainability, and climate resilience,” Flatter said in a news release. “Greentown Labs is, and has always been, a home for entrepreneurs and a powerhouse of collaboration and innovation.”

Previously, Flatter worked to launch TomorrowNow out of tomorrow.io, a Boston-based AI-powered weather intelligence and satellite technology company. The organization secured millions in climate philanthropy from partners, including the Gates Foundation, which helped deliver cutting-edge climate solutions to millions of African farmers weekly.

Flatter also spent 10 years at the Massachusetts Institute of Technology (MIT), where she was a senior lecturer and led global initiatives at the intersection of technology and social impact. Her research work includes time at Langer Lab and Sun Catalytix, an MIT – ARPA-E-funded spin-out that focused on energy storage solutions inspired by natural photosynthesis. Flatter is also an Acumen Rockefeller Global Food Systems Fellow and was closely involved with Greentown Labs when it was founded in Boston in 2011, according to the release.

“It’s rare to find an individual who has impressive climate and energy expertise along with nonprofit and entrepreneurial leadership—we’re fortunate Georgie brings all of this and more to Greentown Labs,” Bobby Tudor, Greentown Labs Board Chair and Chairman of the Houston Energy Transition Initiative, said in a news release.

Flatter will collaborate with Kevin Dutt, Greentown’s Interim CEO, and also continue to serve on Greentown’s Board of Directors, which was recently announced in December and contributed to a successful $4 million funding round. She’s also slated to speak at CERAWeek next month.

“In this next chapter, I’m excited to build on our entrepreneurial roots and the strength of our ever-growing communities in Boston and Houston,” Flatter added in a news release. “Together, we will unite entrepreneurs, partners, and resources to tackle frontier challenges and scale breakthrough technologies.”

Greentown also named Naheed Malik its new chief financial officer last month. The announcements come after Greentown’s former CEO and president, Kevin Knobloch, announced that he would step down in July 2024 after less than a year in the role.

TMC, Memorial Hermann launch partnership to spur new patient care technologies

medtech partnership

Texas Medical Center and Memorial Hermann Health System have launched a new collaboration for developing patient care technology.

Through the partnership, Memorial Hermann employees and physicians will now be able to participate in the TMC Center for Device Innovation (CDI), which will assist them in translating product innovation ideas into working prototypes. The first group of entrepreneurs will pitch their innovations in early 2026, according to a release from TMC.

“Memorial Hermann is excited to launch this new partnership with the TMC CDI,” Ini Ekiko Thomas, vice president of information technology at Memorial Hermann, said in the news release. “As we continue to grow (a) culture of innovation, we look forward to supporting our employees, affiliated physicians and providers in new ways.”

Mentors from Memorial Hermann, TMC Innovation and industry experts with specialties in medicine, regulatory strategy, reimbursement planning and investor readiness will assist with the program. The innovators will also gain access to support systems like product innovation and translation strategy, get dedicated engineering and machinist resources and personal workbench space at the CDI.

“The prototyping facilities and opportunities at TMC are world-class and globally recognized, attracting innovators from around the world to advance their technologies,” Tom Luby, chief innovation officer at TMC Innovation Factor, said in the release.

Memorial Hermann says the partnership will support its innovation hub’s “pilot and scale approach” and hopes that it will extend the hub’s impact in “supporting researchers, clinicians and staff in developing patentable, commercially viable products.”

“We are excited to expand our partnership with Memorial Hermann and open the doors of our Center for Device Innovation to their employees and physicians—already among the best in medical care,” Luby added in the release. “We look forward to seeing what they accomplish next, utilizing our labs and gaining insights from top leaders across our campus.”

Google to invest $40 billion in AI data centers in Texas

Google is investing a huge chunk of money in Texas: According to a release, the company will invest $40 billion on cloud and artificial intelligence (AI) infrastructure, with the development of new data centers in Armstrong and Haskell counties.

The company announced its intentions at a meeting on November 14 attended by federal, state, and local leaders including Gov. Greg Abbott who called it "a Texas-sized investment."

Google will open two new data center campuses in Haskell County and a data center campus in Armstrong County.

Additionally, the first building at the company’s Red Oak campus in Ellis County is now operational. Google is continuing to invest in its existing Midlothian campus and Dallas cloud region, which are part of the company’s global network of 42 cloud regions that deliver high-performance, low-latency services that businesses and organizations use to build and scale their own AI-powered solutions.

Energy demands

Google is committed to responsibly growing its infrastructure by bringing new energy resources onto the grid, paying for costs associated with its operations, and supporting community energy efficiency initiatives.

One of the new Haskell data centers will be co-located with — or built directly alongside — a new solar and battery energy storage plant, creating the first industrial park to be developed through Google’s partnership with Intersect and TPG Rise Climate announced last year.

Google has contracted to add more than 6,200 megawatts (MW) of net new energy generation and capacity to the Texas electricity grid through power purchase agreements (PPAs) with energy developers such as AES Corporation, Enel North America, Intersect, Clearway, ENGIE, SB Energy, Ørsted, and X-Elio.

Water demands

Google’s three new facilities in Armstrong and Haskell counties will use air-cooling technology, limiting water use to site operations like kitchens. The company is also contributing $2.6 million to help Texas Water Trade create and enhance up to 1,000 acres of wetlands along the Trinity-San Jacinto Estuary. Google is also sponsoring a regenerative agriculture program with Indigo Ag in the Dallas-Fort Worth area and an irrigation efficiency project with N-Drip in the Texas High Plains.

In addition to the data centers, Google is committing $7 million in grants to support AI-related initiatives in healthcare, energy, and education across the state. This includes helping CareMessage enhance rural healthcare access; enabling the University of Texas at Austin and Texas Tech University to address energy challenges that will arise with AI, and expanding AI training for Texas educators and students through support to Houston City College.
