An innovative Houston-area company is on a mission to make using hydrogen energy easier and cheaper.

A recently announced partnership with investment firm, Balcor Companies, will help make this a reality as Kaizen Clean Energy looks to make hydrogen energy more accessible, reliable and affordable. Announced July 6, Balcor now has an ownership stake in Kaizen. The terms of the deal were not disclosed.

The company, based in Tomball, has developed a “micro grid” hydrogen power station — a mobile, scalable energy source that can be used anywhere, anytime.

Balcor Companies Founder and Director Chris Balat says his company is looking at their stake in KCE as an investment in shaping a more sustainable world.

“We are thrilled to make our first foray into the energy sector with Kaizen Energy as our trusted partner,” he says in a statement. "Our association with Kaizen is a testament to our commitment towards a sustainable future, driving positive change in the world while delivering value to our stakeholders.”

Kaizen's mission is to succeed where electric grids fail. One fallback source to help strained electric grids has typically been diesel generators. However, diesel generators increase local emissions which produce a significant amount of air pollution and health concerns. Kaizen’s hydrogen generators can be used to power buildings, homes, hospitals, data centers, events, and farm equipment. They are portable, which means it does not require any excessive infrastructure.

“Our system allows customers the ability to have renewable energy anywhere in the world in a very short time frame,” said Eric Smith, co-founder of KCE. “For EV charging, for power generation, to replace a diesel generator.”

Smith tells EnergyCapitalhtx the concept is very attractive to corporations who lease buildings as building out a permanent infrastructure could be costly and time consuming.

Robert Meaney, a Texas Tech engineering graduate, founded Kaizen Clean Energy in 2020, along with Eric Smith and Craig Klaasmeyer. Meaney designed the technology using a mixture of methanol and water to create hydrogen. A 330-gallon tank of the mixture produces about 150 kilograms of hydrogen — or 1.6 megawatt-hours of energy. The mixture lowers the risks of many of the drawbacks of hydrogen usage. For example, it can be stored for longer periods and transported long distances safely.

The microgrid fits into a small container and can be dropped on site at remote locations or in heavily congested grid areas. It also eliminates the cost of hydrogen transportation by generating hydrogen on-site with commonly available methanol, which can be both used for hydrogen fuel and converted to electricity for electric vehicle charging. This microgrid technology can both connect to the grid to supplement available power, or can be used during a power outage.

To put this energy source to use, KCE has partnered with Extreme E, an international off-road racing series that is part of Formula 1 and uses electric SUV’s to race in remote parts of the world. Kaizen’s units are also being used at a fleet-charging location in Los Angeles.

A View From HETI

Engineers at Rice University have developed a cleaner, innovative process to turn end-of-life lithium-ion battery waste into new lithium feedstock.

The findings, recently published in the journal Joule, demonstrate how the team’s new “recharge-to-recycle” reactor recharges the battery’s waste cathode materials to coax out lithium ions into water. The team was then able to form high-purity lithium hydroxide, which was clean enough to feed directly back into battery manufacturing.

The study has major implications for the electric vehicle sector, which significantly contributes to the waste stream from end-of-life battery packs. Additionally, lithium tends to be expensive to mine and refine, and current recycling methods are energy- and chemical-intensive.

“Directly producing high-purity lithium hydroxide shortens the path back into new batteries,” Haotian Wang, associate professor of chemical and biomolecular engineering, co-corresponding author of the study and co-founder of Solidec, said in a news release. “That means fewer processing steps, lower waste and a more resilient supply chain.”

Sibani Lisa Biswal, chair of Rice’s Department of Chemical and Biomolecular Engineering and the William M. McCardell Professor in Chemical Engineering, also served as co-corresponding author on the study.

“We asked a basic question: If charging a battery pulls lithium out of a cathode, why not use that same reaction to recycle?” Biswal added in the release. “By pairing that chemistry with a compact electrochemical reactor, we can separate lithium cleanly and produce the exact salt manufacturers want.”

The new process also showed scalability, according to Rice. The engineers scaled the device to 20 square centimeters, then ran a 1,000-hour stability test and processed 57 grams of industrial black mass supplied by industry partner Houston-based TotalEnergies. The results produced lithium hydroxide that was more than 99 percent pure. It also maintained an average lithium recovery rate of nearly 90 percent over the 1,000-hour test, showing its durability. The process also worked across multiple battery chemistries, including lithium iron phosphate, lithium manganese oxide and nickel-manganese-cobalt variants.

Looking ahead, the team plans to scale the process and consider ways it can sustain high efficiency for greater lithium hydroxide concentrations.

“We’ve made lithium extraction cleaner and simpler,” Biswal added in the release. “Now we see the next bottleneck clearly. Tackle concentration, and you unlock even better sustainability.
