A new partnership between The Hertz Corp. and the City of Houston will bring 2,100 rental electric vehicles to Houston, according to an announcement from the organizations earlier this week.

Dubbed Hertz Electrifies Houston, the program aims to boost Houston's EV rental fleet, as well add to the city's charging infrastructure and EV education and training opportunities.

The new vehicles will come from automakers Tesla, Polestar, and GM and can be rented to leisure and business customers, as well as rideshare drivers.

In partnership with bp pulse, Hertz Electrifies Houston will also bring a new EV fast-charging hub to Hobby Airport that's designed to serve ride-hail, taxi fleets and the general public.

"Our goal is to convert all non-emergency, light-duty municipal vehicles to electric by 2030," Mayor Sylvester Turner says in a statement. "This partnership with Hertz will provide an invaluable boost to achieve this goal and the goal of our Climate Action Plan for Houston to be a net-zero city by 2050."

In addition to the new fleet and charging hub, Hertz announced it will also donate an EV to Lone Star College-North Harris to help the college provide EV training to students in its auto servicing curriculum.

"Lone Star College-North Harris houses one of top automotive programs in Texas," Archie Blanson, president of Lone Star College-North Harris, says in the statement. "To make our students competitive and meet industry demand, we must ensure we are bringing the latest technologies, including a diversified fleet of EVs into the classroom.”

Earlier this month, Hertz also launched a Hertz Electrifies program in Denver. The initiative aims to bring 5,200 rental EVs to Denver. In 2022, the company first announced its plan to partner with bp pulse to install a national network of EV charging solutions for its customers.

Houston also has grown into a hub for EV and EV charging innovation recently. Houston-based Zeta Energy is leading efforts to develop efficient EV batteries, and received $4 million in funding from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program earlier this year.

Houston's Revterra has also created a kinetic energy storage system that enables rapid EV charging. The company’s founder and CEO, Ben Jawdat, spoke about the energy transition on the Houston Innovators Podcast last month.

Cleantech incubator announces location in Houston, names newest partners

Greentown's moving in

After announcing its plans to expand to Houston in June, Boston-based Greentown Labs has selected its site for its cleantech startup and tech incubator.

Houston Mayor Sylvester Turner and the Greater Houston Partnership announced that Greentown Houston will be opening in the Innovation District, being developed by Rice Management Co. and home to The Ion. The site is located at 4200 San Jacinto St., which was Houston's last remaining Fiesta grocery story before it closed in July.

The facility is expected to open this coming spring and will feature 40,000 square feet of prototyping lab, office, and community space that can house about 50 startups, totaling 200 to 300 employees.

"We are thrilled to announce the selection of Greentown Labs' inaugural location in partnership with RMC, the City of Houston, the Partnership, and leading global energy and climate impact-focused companies," says Emily Reichert, CEO of Greentown Labs, in a press release. "In order to meet the urgent challenge of climate change, we must engage the talent and assets of major ecosystems around the country. We look forward to catalyzing the Houston ecosystem's support for climatetech startups as we work together toward a sustainable future for all."

Greentown Labs launched in 2011 as community of climatetech and cleantech innovators bringing together startups, corporates, investors, policymakers, and more to focus on scaling climate solutions. Greentown Labs' first location is 100,000 square feet and located just outside of Boston in Somerville, Massachusetts. Currently, it's home to more than 100 startups and has supported more than 280 startups since the incubator's founding. According to the release, these startups have created more than 6,500 jobs and raised over $850 million in funding

"We are so pleased that Greentown Houston will locate in the heart of the Innovation District, where they will seamlessly integrate into the region's robust energy innovation ecosystem of major corporate energy R&D centers, corporate venture arms, VC-backed energy startups, and other startup development organizations supporting energy technology," says Susan Davenport, chief economic development officer at the Greater Houston Partnership, in the release. "Houston truly is the hub of the global energy industry, and Greentown Houston will ensure we continue to attract the next generation of energy leaders who will create and scale innovations that will change the world."

Greentown Houston, which previously announced several founding partners in June, has just named new partners, including: RMC, Microsoft, Saint-Gobain, and Direct Energy. According to the release, Greentown Houston is also looking for Grand Opening Partners. Naturgy and and FCC Environmental Services (FCC) are the first to join on as a grand opening partners, and startups and prospective partners can reach out for more information via this form.

Reichert previously told InnovationMap that it was looking for an existing industrial-type building that could be retrofitted to meet the needs of industrial startups that need lab space. She also said that this approach is very similar to how they opened their first location.

The new location will be in the 16-acre Innovation District that's being developed by RMC, which will be anchored by The Ion, a 270,000-square-foot hub that is being renovated from the former Sears building.

"What we love about Greentown Labs as much as its commitment to helping Houston become a leader in energy transition and climate change action is its proven track record of job creation through the support of local visionaries and entrepreneurs," says Ryan LeVasseur, managing director of Direct Real Estate at RMC, in the release. "Greentown Houston, like The Ion, is a great catalyst for growing the Innovation District and expanding economic opportunities for all Houstonians. We're thrilled Greentown Labs selected Houston for its first expansion and are honored it will be such a big part of the Innovation District moving forward."

Acquiring the new Greentown location is a big win for the mayor, who released the city's Climate Action Plan earlier this year. The plan lays out a goal to make Houston carbon neutral by 2050.

"We are proud to welcome Greentown Labs to Houston, and we are excited about the new possibilities this expansion will bring to our City's growing innovation ecosystem," says Turner in the release. "Organizations and partners like Greentown Labs will play a vital role in helping our City meet the goals outlined in the Climate Action Plan and will put us on the right track for becoming a leader in the global energy transition. The City of Houston looks forward to witnessing the innovation, growth, and prosperity Greentown Labs will bring to the Energy Capital of the World."

Greentown Labs will host a celebratory networking event on September 24 at 4 p.m. Registration for the EnergyBar is open here.

Houston foundation grants $27M to support Texas chemistry research

fresh funding

Houston-based The Welch Foundation has doled out $27 million in its latest round of grants for chemical research, equipment and postdoctoral fellowships.

According to a June announcement, $25.5 million was allocated for the foundation's longstanding research grants, which provide $100,000 per year in funding for three years to full-time, regular tenure or tenure-track faculty members in Texas. The foundation made 85 grants to faculty at 16 Texas institutions for 2025, including:

  • Michael I. Jacobs, assistant professor in the chemistry and biochemistry department at Texas State University, who is investigating the structure and thermodynamics of intrinsically disordered proteins, which could "reveal clues about how life began," according to the foundation.
  • Kendra K. Frederick, assistant professor in the biophysics department at The University of Texas Southwestern Medical Center, who is studying a protein linked to Parkinson’s disease.
  • Jennifer S. Brodbelt, professor in chemistry at The University of Texas at Austin, who is testing a theory called full replica symmetry breaking (fullRSB) on glass-like materials, which has implications for complex systems in physics, chemistry and biology.

Additional funding will be allocated to the Welch Postdoctoral Fellows of the Life Sciences Research Foundation. The program provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas. Two fellows from Rice University and Baylor University will receive $100,000 annually for three years.

The Welch Foundation also issued $975,000 through its equipment grant program to 13 institutions to help them develop "richer laboratory experience(s)." The universities matched funds of $352,346.

Since 1954, the Welch Foundation has contributed over $1.1 billion for Texas-nurtured advancements in chemistry through research grants, endowed chairs and other chemistry-related ventures. Last year, the foundation granted more than $40.5 million in academic research grants, equipment grants and fellowships.

“Through funding basic chemical research, we are actively investing in the future of humankind,” Adam Kuspa, president of The Welch Foundation, said the news release. “We are proud to support so many talented researchers across Texas and continue to be inspired by the important work they complete every day.”

New Houston biotech co. developing capsules for hard-to-treat tumors

biotech breakthroughs

Houston company Sentinel BioTherapeutics has made promising headway in cancer immunotherapy for patients who don’t respond positively to more traditional treatments. New biotech venture creation studio RBL LLC (pronounced “rebel”) recently debuted the company at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago.

Rima Chakrabarti is a neurologist by training. Though she says she’s “passionate about treating the brain,” her greatest fervor currently lies in leading Sentinel as its CEO. Sentinel is RBL’s first clinical venture, and Chakrabarti also serves as cofounder and managing partner of the venture studio.

The team sees an opportunity to use cytokine interleukin-2 (IL-2) capsules to fight many solid tumors for which immunotherapy hasn't been effective in the past. “We plan to develop a pipeline of drugs that way,” Chakrabarti says.

This may all sound brand-new, but Sentinel’s research goes back years to the work of Omid Veiseh, director of the Rice Biotechnology Launch Pad (RBLP). Through another, now-defunct company called Avenge Bio, Veiseh and Paul Wotton — also with RBLP and now RBL’s CEO and chairman of Sentinel — invested close to $45 million in capital toward their promising discovery.

From preclinical data on studies in mice, Avenge was able to manufacture its platform focused on ovarian cancer treatments and test it on 14 human patients. “That's essentially opened the door to understanding the clinical efficacy of this drug as well as it's brought this to the attention of the FDA, such that now we're able to continue that conversation,” says Chakrabarti. She emphasizes the point that Avenge’s demise was not due to the science, but to the company's unsuccessful outsourcing to a Massachusetts management team.

“They hadn't analyzed a lot of the data that we got access to upon the acquisition,” explains Chakrabarti. “When we analyzed the data, we saw this dose-dependent immune activation, very specific upregulation of checkpoints on T cells. We came to understand how effective this agent could be as an immune priming agent in a way that Avenge Bio hadn't been developing this drug.”

Chakrabarti says that Sentinel’s phase II trials are coming soon. They’ll continue their previous work with ovarian cancer, but Chakrabarti says that she also believes that the IL-2 capsules will be effective in the treatment of endometrial cancer. There’s also potential for people with other cancers located in the peritoneal cavity, such as colorectal cancer, gastrointestinal cancer and even primary peritoneal carcinomatosis.

“We're delivering these capsules into the peritoneal cavity and seeing both the safety as well as the immune activation,” Chakrabarti says. “We're seeing that up-regulation of the checkpoint that I mentioned. We're seeing a strong safety signal. This drug was very well-tolerated by patients where IL-2 has always had a challenge in being a well-tolerated drug.”

When phase II will take place is up to the success of Sentinel’s fundraising push. What we do know is that it will be led by Amir Jazaeri at MD Anderson Cancer Center. Part of the goal this summer is also to create an automated cell manufacturing process and prove that Sentinel can store its product long-term.

“This isn’t just another cell therapy,” Chakrabarti says.

"Sentinel's cytokine factory platform is the breakthrough technology that we believe has the potential to define the next era of cancer treatment," adds Wotton.

How Houston's innovation sector fared in 2025 Texas legislative session

That's a Wrap

The Greater Houston Partnership is touting a number of victories during the recently concluded Texas legislative session that will or could benefit the Houston area. They range from billions of dollars for dementia research to millions of dollars for energy projects.

“These wins were only possible through deep collaboration, among our coalition partners, elected officials, business and community leaders, and the engaged members of the Partnership,” according to a partnership blog post. “Together, we’ve demonstrated how a united voice for Houston helps drive results that benefit all Texans.”

In terms of business innovation, legislators carved out $715 million for nuclear, semiconductor, and other economic development projects, and a potential $1 billion pool of tax incentives through 2029 to support research-and-development projects. The partnership said these investments “position Houston and Texas for long-term growth.”

Dementia institute

One of the biggest legislative wins cited by the Greater Houston Partnership was passage of legislation sponsored by Sen. Joan Huffman, a Houston Republican, to provide $3 billion in funding over 10 years for the Dementia Prevention and Research Institute of Texas. Voters will be asked in November to vote on a ballot initiative that would set aside $3 billion for the new institute.

The dementia institute would be structured much like the Cancer Prevention and Research Institute of Texas (CPRIT), a state agency that provides funding for cancer research in the Lone Star State. Since its founding in 2008, CPRIT has awarded nearly $3.9 billion in research grants.

“By establishing the Dementia Prevention and Research Institute of Texas, we are positioning our state to lead the charge against one of the most devastating health challenges of our time,” Huffman said. “With $3 billion in funding over the next decade, we will drive critical research, develop new strategies for prevention and treatment, and support our healthcare community. Now, it’s up to voters to ensure this initiative moves forward.”

More than 500,000 Texans suffer from some form of dementia, including Alzheimer’s disease, according to Lt. Gov. Dan Patrick.

“With a steadfast commitment, Texas has the potential to become a world leader in combating [dementia] through the search for effective treatments and, ultimately, a cure,” Patrick said.

Funding for education

In the K-12 sector, lawmakers earmarked an extra $195 million for Houston ISD, $126.7 million for Cypress-Fairbanks ISD, $103.1 million for Katy ISD, $80.6 million for Fort Bend ISD, and $61 million for Aldine ISD, the partnership said.

In higher education, legislators allocated:

     
  • $1.17 billion for the University of Houston College of Medicine, University of Texas Health Science Center at Houston, UT MD Anderson Cancer Center, and Baylor College of Medicine
  • $922 million for the University of Houston System
  • $167 million for Texas Southern University
  • $10 million for the Center for Biotechnology at San Jacinto College.

Infrastructure

In the infrastructure arena, state lawmakers:

     
  • Approved $265 million for Houston-area water and flood mitigation projects, including $100 million for the Lynchburg Pump Station
  • Created the Lake Houston Dredging and Maintenance District
  • Established a fund for the Gulf Coast Protection District to supply $550 million for projects to make the coastline and ship channel more resilient

"Nuclear power renaissance"

House Bill 14 (HB 14) aims to lead a “nuclear power renaissance in the United States,” according to Texas Gov. Greg Abbott’s office. HB 14 establishes the Texas Advanced Nuclear Energy Office, and allocates $350 million for nuclear development and deployment. Two nuclear power plants currently operate in Texas, generating 10 percent of the energy that feeds the Electric Reliability Council Texas (ERCOT) power grid.

“This initiative will also strengthen Texas’ nuclear manufacturing capacity, rebuild a domestic fuel cycle supply chain, and train the future nuclear workforce,” Abbott said in a news release earlier this year.

One of the beneficiaries of Texas’ nuclear push could be Washington, D.C.-based Last Energy, which plans to build 30 micro-nuclear reactors near Abilene to serve power-gobbling data centers across the state. Houston-based Pelican Energy Partners also might be able to take advantage of the legislation after raising a $450 million fund to invest in companies that supply nuclear energy services and equipment.

Reed Clay, president of the Texas Nuclear Alliance, called this legislation “the most important nuclear development program of any state.”

“It is a giant leap forward for Texas and the United States, whose nuclear program was all but dead for decades,” said Clay. “With the passage of HB 14 and associated legislation, Texas is now positioned to lead a nuclear renaissance that is rightly seen as imperative for the energy security and national security of the United States.”
