This Houston organization is on a mission to shrink the city's carbon footprint — one EV at a time

Equity and environmental impact characteristics often used to describe a company’s outlook on increased sustainability and fighting climate change.

Evolve Houston, which was founded in 2018 through Houston’s Climate Action Plan and relaunched last year, is one of the organizations leading the way, and now with their Grant Tracker program, they are giving back to those who are giving back to the planet.

“Raising awareness is a critical part of accelerating a new technology, this includes awareness of incentives that individuals and fleets in the Greater Houston region may be eligible for,” Casey Brown, executive director and president, tells EnergyCapital. “Beyond understanding incentives, most Houstonians have not experienced an EV for themselves. With the support of our Founding Members (Shell, NRG Energy, CenterPoint Energy, University of Houston, and the City of Houston), we offer educational and experiential ways for Houstonians to interact with EVs and learn more about the benefits.”

The Grant Tracker aims to make it easier to find funding opportunities, and assist with current grants available to organizations and individuals that are committed to a goal of zero emissions. The tracker serves as a tool to assist with purchasing an EV and charging equipment. Ultimately, Evolve wants to assist and fund those looking to make the transition to electric.

Anup Parikh and his company Pangea Charging, through EVOLVE, was granted a project to help bring charging capacity for EVs to help build the infrastructure in areas and apartment complexes that traditionally would not have them.

“People see electric vehicles as high-end and a luxury lifestyle, when in fact it can happen for everybody,” Parikh said in a promotional video.

In addition to the Grant Tracker program, Evolve’s Mobility Microgrant Initiative will partner with local nonprofits,community reviewers, and corporate catalysts to award funding to eMobility projects aimed at serving mobility needs in Houston's underserved neighborhoods. In July, Evolve teamed up with RYDE and District D Council Member Carolyn Evans-Shabazz to bring the free on-demand electric local shuttle service to residents in the Third Ward area, which was one of the many microgrants associated with the project. RYDE’s service in the area has been extended recently into the fall and “until further notice” according to a newsletter from EVOLVE.

“Private investments in this sector follow EV adoption,“ Brown says. “Investing in areas early creates more opportunity for EV technology interaction and benefits.

"We are excited about the success of our Equity Program and the exciting projects it has funded across Houston," he continues. "Today, we accomplish this through our eMobility Microgrant Initiative, a community-led investment program focused on historically disadvantaged communities, and aimed to tackle community needs with electric vehicle technologies. We have had a very successful Round 1 of investments this year and we are excited to announce round two grant winners in January of 2024.”

As Evolve continues to evolve its sphere of influence, the company still aims for its goal to have half of the vehicles in the city be electric by 2030. The company says that EVs should be for all Houstonians, not just for some.

“Houston maintains some of the lowest population density and longest commute distances of major U.S. cities, and we have an immense amount of business and goods that flow through Houston,” Brown said. “We see a landscape that can uniquely achieve larger financial and environmental benefits of EV technologies. One way that we share these benefits is being the Presenting Sponsor of the Houston Auto Show. We also summarize the local EV sector through our R.I.S.E. report and maintain an actionable, forward view in our EV Roadmap; both sources can be found on our website and are undergoing a refresh as we close 2023.”

A research lab at the University of Houston has developed a new type of material for sodium-ion batteries that could make them more efficient and boost their energy performance.

Led by Pieremanuele Canepa, Robert Welch assistant professor of electrical and computer engineering at UH, the Canepa Research Laboratory is working on a new material called sodium vanadium phosphate, which improves sodium-ion battery performance by increasing the energy density. Energy density is the amount of energy stored per kilogram, and the new material can do so by more than 15 percent. With a higher energy density of 458 watt-hours per kilogram — compared to the 396 watt-hours per kilogram in older sodium-ion batteries — this material brings sodium technology closer to competing with lithium-ion batteries, according to the researchers.

The Canepa Lab used theoretical expertise and computational methods to discover new materials and molecules to help advance clean energy technologies. The team at UH worked with the research groups headed by French researchers Christian Masquelier and Laurence Croguennec from the Laboratoire de Reáctivité et de Chimie des Solides, which is a CNRS laboratory part of the Université de Picardie Jules Verne, in Amiens France, and the Institut de Chimie de la Matière Condensée de Bordeaux, Université de Bordeaux, Bordeaux, France for the experimental work on the project.

The researchers then created a battery prototype using the new materia sodium vanadium phosphate, which demonstrated energy storage improvements. The material is part of a group called “Na superionic conductors” or NaSICONs, which is made to let sodium ions move in and out of the battery during charging and discharging.

“The continuous voltage change is a key feature,” Canepa says in a news release. “It means the battery can perform more efficiently without compromising the electrode stability. That’s a game-changer for sodium-ion technology.”

The synthesis method used to create sodium vanadium phosphate may be applied to other materials with similar chemistries, which could create new opportunities for advanced energy storage. A paper of this work was published in the journal Nature Materials.

"Our goal is to find clean, sustainable solutions for energy storage," Canepa adds. "This material shows that sodium-ion batteries can meet the high-energy demands of modern technology while being cost-effective and environmentally friendly."
