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.

Houston-based battery innovators receive $4M in federal funding

money moves

Houston-based Zeta Energy announced this week that it was selected to receive $4 million in federal funding for the development of efficient electric vehicle batteries.

The funds come from the U.S. Department of Energy's ARPA-E Electric Vehicles for American Low-Carbon Living, or EVs4ALL, program, which aims to increase the number of EVs on the roads by boosting the country’s supply chain of affordable, convenient, reliable and safe batteries.

Zeta Energy is one of 12 groups in the U.S. to receive funding from the program, which awarded $42 million in total.

“Electric vehicle sales in America have tripled since the start of this Administration and by addressing battery efficiency, resiliency and affordability, the projects announced today will make EVs attractive to even more drivers,” U.S. Secretary of Energy Jennifer M. Granholm said in a statement released earlier this week. “This is a win-win for our efforts to fight climate change and power America’s clean transportation future with technologies produced by researchers and scientists right here at home.”

Other teams to receive funding include 24M Technologies, national laboratories and universities like The Ohio State University, University of Maryland, Virginia Tech, among others. Zeta is the only Texas-based company to receive funds. It received one of the largest grants among the group.

"We are thrilled to have been selected for funding by the ARPA-E EVs4ALL program," Zeta Energy CEO Tom Pilette said in a statement. "We have been working hard to make this technology a reality, and we are really grateful to receive this recognition of the promise of our technology and the progress we have made on it."

Zeta Energy is known for its lithium sulfur batteries that traditionally have not been long lasting. While sulfur is an economical and abundant material, it traditionally would dissolve after a few uses in lithium sulfur batteries.

However, Zeta uses its proprietary sulfur-based cathodes and lithium metal anodes that have shown to have higher capacity and density and better safety profiles, according to the company's website.

According to ARPAE, the company will create a new anode that will "be highly accessible and rechargeable" with the funding.

Houston-based battery innovators close $23M series A

money moves

Houston-based Zeta Energy announced this month that it has closed a $23 million series A round led by New York VC firm Moore Strategic Ventures.

The funding will be used to expand Zeta's lab facility in the Houston area and further commercialize the company's innovative batteries for electric vehicles and energy storage.

"We are delighted to have Moore Strategic Ventures join Zeta Energy. Moore's focus on transportation, advanced materials, energy, and clean tech aligns perfectly with Zeta's strategic objectives," Charles Maslin, founder and CEO of Zeta Energy, said in a statement. "We are so excited to work together to help the world transition to clean energy and build a more sustainable future."

Founded in 2014, Zeta develops affordable and sustainable rechargeable batteries and is known for its lithium sulfur battery system. The system utilizes Zeta's proprietary sulfur-based cathodes and lithium metal anodes that have shown to have higher capacity and density and better safety profiles, according to the company's website.

The company is slated to move to a new 12,000-square-foot facility in West Houston in Q2 where it will employ 40 individuals, including 25 researchers, engineers, and developers.

"Houston is the ideal location for us to advance our core battery and materials technology," Zeta COO Tom Pilette said in a statement. "With this new facility we will be able to demonstrate the performance and cost characteristics of our proprietary technology and help accelerate electrification and the transition to green energy and beyond."

The news comes on the heels of Austin-based Tesla revealing details on a new "energy-storage park" South of Houston, equipped with 81 Megapack batteries that store clean energy. The site is predicted to help ease the impact of power grid losses in the state.

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
