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'sClimate 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.

2 Houston space tech cos. celebrate major tech milestones

big wins

Two Houston aerospace companies — Intuitive Machines and Venus Aerospace — have reached testing milestones for equipment they’re developing.

Intuitive Machines recently completed the first round of “human in the loop” testing for its Moon RACER (Reusable Autonomous Crewed Exploration Rover) lunar terrain vehicle. The company conducted the test at NASA’s Johnson Space Center.

RACER is one of three lunar terrain vehicles being considered by NASA for the space agency’s Artemis initiative, which will send astronauts to the moon.

NASA says human-in-the-loop testing can reveal design flaws and technical problems, and can lead to cost-efficient improvements. In addition, it can elevate the design process from 2D to 3D modeling.

Intuitive Machines says the testing “proved invaluable.” NASA astronauts served as test subjects who provided feedback about the Moon RACER’s functionality.

The Moon RACER, featuring a rechargeable electric battery and a robotic arm, will be able to accommodate two astronauts and more than 880 pounds of cargo. It’s being designed to pull a trailer loaded with more than 1,760 pounds of cargo.

Another Houston company, Venus Aerospace, recently achieved ignition of its VDR2 rocket engine. The engine, being developed in tandem with Ohio-based Velontra — which aims to produce hypersonic planes — combines the functions of a rotating detonation rocket engine with those of a ramjet.

A rotating detonation rocket engine, which isn’t equipped with moving parts, rapidly burns fuel via a supersonic detonation wave, according to the Air Force Research Laboratory. In turn, the engine delivers high performance in a small volume, the lab says. This savings in volume can offer range, speed, and affordability benefits compared with ramjets, rockets, and gas turbines.

A ramjet is a type of “air breathing” jet engine that does not include a rotary engine, according to the SKYbrary electronic database. Instead, it uses the forward motion of the engine to compress incoming air.

A ramjet can’t function at zero airspeed, so it can’t power an aircraft during all phases of flight, according to SKYbrary. Therefore, it must be paired with another kind of propulsion, such as a rotating detonation rocket engine, to enable acceleration at a speed where the ramjet can produce thrust.

“With this successful test and ignition, Venus Aerospace has demonstrated the exceptional ability to start a [ramjet] at takeoff speed, which is revolutionary,” the company says.

Venus Aerospace plans further testing of its engine in 2025.

METRO rolls out electric shuttles for downtown Houston commuters

on a roll

The innovative METRO microtransit program will be expanding to the downtown area, the Metropolitan Transit Authority of Harris County announced on Monday.

“Microtransit is a proven solution to get more people where they need to go safely and efficiently,” Houston Mayor John Whitmire said in a statement. “Connected communities are safer communities, and bringing microtransit to Houston builds on my promise for smart, fiscally-sound infrastructure growth.”

The program started in June 2023 when the city’s nonprofit Evolve Houston partnered with the for-profit Ryde company to offer free shuttle service to residents of Second and Third Ward. The shuttles are all-electric and take riders to bus stops, medical buildings, and grocery stores. Essentially, it works as a traditional ride-share service but focuses on multiple passengers in areas where bus access may involve hazards or other obstacles. Riders access the system through the Ride Circuit app.

So far, the microtransit system has made a positive impact in the wards according to METRO. This has led to the current expansion into the downtown area. The system is not designed to replace the standard bus service, but to help riders navigate to it through areas where bus service is more difficult.

“Integrating microtransit into METRO’s public transit system demonstrates a commitment to finding innovative solutions that meet our customers where they are,” said METRO Board Chair Elizabeth Gonzalez Brock. “This on-demand service provides a flexible, easier way to reach METRO buses and rail lines and will grow ridership by solving the first- and last-mile challenges that have hindered people’s ability to choose METRO.”

The City of Houston approved a renewal of the microtransit program in July, authorizing Evolve Houston to spend $1.3 million on it. Some, like council member Letitia Plummer, have questioned whether microtransit is really the future for METRO as the service cuts lines such as the University Corridor.

However, the microtransit system serves clear and longstanding needs in Houston. Getting to and from bus stops in the city with its long blocks, spread-out communities, and fickle pedestrian ways can be difficult, especially for poor or disabled riders. While the bus and rail work fine for longer distances, shorter ones can be underserved.

Even in places like downtown where stops are plentiful, movement between them can still involve walks of a mile or more, and may not serve for short trips.

“Our microtransit service is a game-changer for connecting people, and we are thrilled to launch it in downtown Houston,” said Evolve executive director Casey Brown. “The all-electric, on-demand service complements METRO’s existing fixed-route systems while offering a new solution for short trips. This launch marks an important milestone for our service, and we look forward to introducing additional zones in the new year — improving access to public transit and local destinations.”
