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 professor awarded $2.6M grant for retina, neurological research

seeing green

University of Houston College of Optometry Professor John O’Brien has received a $2.6 million grant from the National Eye Institute to continue his research on the retina and neurological functions.

O’Brien is considered a leading expert in retinal neuroscience with more than 20 years of research in the field. The new funding will allow O’Brien and his team to continue to study the dense assembly of proteins associated with electrical synapses, or gap junctions, in the retina.

Gap junctions transfer electrical signals between neurons. And the plasticity of gap junctions changes the strength of a synapse, in turn changing how visual information is processed. Previous research has shown that reduced functions of electrical synapses could be linked to autism, while their hyperfunction may lead to seizures.

“The research we propose will significantly advance our understanding of the molecular complexes that control the function of electrical synapses,” O’Brien said in a news release.

The team at UH will work to identify the proteins and examine how they impact electrical synapses. It is particularly interested in the Connexin 36, or Cx36, protein. According to O’Brien, phosphorylation of Cx36, a short-term chemical modification of the protein, serves as a key driver of plasticity. And the protein has been linked to refractive error development, which is one of the largest vision problems in the world today.

Additionally, OBrien’s research has shown that plasticity is essential for all-day vision, allowing the retina to adjust sensitivity and sharpen images. He has also built a catalog of the core set of proteins surrounding electrical synapses that are conserved across species. His research has been funded by the NEI since 2000.

Capwell Services

Houston-based methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the US and Canada, equivalent to more than 400 million metric tons of CO2e per year. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

Deep Anchor Solutions

Offshore energy consulting and design company Deep Anchor Solutions aims to help expedite the adoption of floating offshore energy infrastructure with its deeply embedded ring anchor (DERA) technology. According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has not raised VC funding, but has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTechNexus LiftOff and others. Lee is an Activate 2025 fellow.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers and rubbers. The company reports that it plans to open its first commercial plant in the next 18 months.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch and lead engineer Trey Sheridan, the company has raised just under $1 million in capital and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch and other organizations.

Torres Orbital Mining (TOM)

Space tech company Torres Orbital Mining aims to pioneer the sustainable extraction and processing of lunar regolith and designs and builds robotic systems for excavating, classifying, and delivering lunar material. The company aims to accelerate a permanent and ethical human presence on the Moon.

The company was founded this year by Luis Torres, a current MBA candidate at Rice Business.

Wellysis USA Inc.

Wellysis USA Inc. works to detect heart rhythm disorders with its continuous ECG/EKG monitor with AI reporting. Its S-Patch cardiac monitor is designed for extended testing periods of up to 14 days on a single battery charge. The device weighs only 9 grams, is waterproof and designed to be comfortable to wear, and is considered to have a high detection rate for arrhythmias. It is ideally suited for patient-centric clinical trials to help physicians make diagnoses faster, cheaper and more conveniently.

It was established in Houston in 2023 and participated in the JLABS SFF Program the same year. It closed a $12 million series B last year. It was founded by CEO Young Juhn, CTO Rick Kim, CFO JungSoo Kim and chief strategy officer JoongWoo Kim.

In his new role, Reale, a longtime leader in Houston’s startup ecosystem, will work to strengthen the innovation district's founder and investor network.

"Here’s what I’ve come to believe: the Ion is not just a building, not just a real estate play, and not just another innovation district. COVID, remote work, and shifting market dynamics changed the rules. Key ingredients like co-working, events, and community, while impactful, are no longer enough on their own," Reale shared on a LinkedIn post announcing the move. "What’s needed are advantages ... We need to intentionally design a system that repeatedly delivers advantages so founders can pull forward their visions."

Reale previously served as executive in residence and venture partner at TMC Venture Fund and co-founded Station Houston. He also serves as managing director of Integr8d Capital. He's an investor and serves on the board of directors for a number of venture-backed companies, including Cart.com, Lionguard and others.

The Ion will host "Today Is Day One – A conversation with John (JR) Reale" to welcome Reale to the role on Tuesday, Oct. 21. Reale will be joined at the event by Heath Butler, partner at Mercury, to discuss their thoughts on shaping Houston's founders ecosystem, as well as the Ion’s Founder Advantage Platform.

"On top of this connected architecture, we will build product. That product will be the Founder Advantage Platform to remove friction, compress time, and compound outcomes," Reale continued on LinkedIn. "This is the system that will drive repeatable experiences, and naturally, make these journeys so much more fun."
