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.

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.
