Visiting Daikin: Houston energy transition innovation is the heart of operations

In the energy capital of the world, we often think and talk about the energy transition and low carbon solutions in the context of energy production and distribution – whether it’s adding more renewables to the grid, reducing the CO2 emissions of our existing energy resources with CCUS and Hydrogen, developing energy storage technology to manage intermittency, or deploying other innovative solutions designed to produce or deliver more energy with fewer emissions – Houston is leading on all fronts.

But these aren’t the only solutions needed as we seek to solve one of the most challenging issues of our time. We cannot focus only on innovating the production and distribution of energy. As the demand for energy grows, locally and globally, we must also think innovatively about reducing the demand for energy, while still maintaining, and improving, quality of life. I had the opportunity recently to visit a company that is doing just that, right here in the Houston region.

Daikin is the world’s leading air conditioning and refrigeration company, with their US headquarters and North America manufacturing facility based right here, just 30 minutes northwest of downtown Houston in Waller, Texas. The Daikin Texas Technology Park, a 4.2 million ft2 facility, equal to 74 football fields, is dedicated to developing, manufacturing and marketing innovative solutions for meeting its customers’ needs while also reducing the energy required to keep people cool. Currently, air conditioning accounts for around 10% of global electricity consumption, with rapid demand growth expected in the future. As electrification becomes a key pathway to the decarbonization of various industries, demand for low-carbon power will continue to grow.

Achieving an affordable, reliable, and low-carbon future will require innovation across the entire energy value chain – from production to consumption, and, as the world’s leading air conditioning manufacturer, Daikin, is leading the way in developing innovative solutions to achieve optimum comfort and energy savings.

Three things struck me during my recent visit to the Daikin Texas Technology Park (DTTP):

  1. Innovation is at the heart of their operation. The integration of engineering and manufacturing in a single location facilitates collaboration and product innovation and accelerates implementation. The LEED Gold Certified facility was also innovatively designed to maximize energy efficiency and minimize environmental impact.
  2. People are a priority. The diversity of the 8000+ employees working at the DTTP was incredible. During the visit, we had the opportunity to see team members from many different backgrounds and with various skills and education working in all parts of their operation. They also offer a STEM scholarship program in partnership with the Waller Area Chamber of Commerce.
  3. They are environmentally focused. Daikin is fully committed to providing energy solutions that improve quality of life while also reducing environmental impact through improved efficiency. The heating and air conditioning products manufactured at the DTTP are some of the most innovative and energy efficient products on the market today – producing a more even temperature and offering as much as a 30% reduction in energy use compared to standard AC systems, all with a considerably smaller footprint.

As someone who spends a great deal of time thinking about the pathways to solving the global dual challenge of more energy with fewer emissions, much of my time is spent learning about innovations on the supply side of energy. It is exciting to learn that there is just as much innovation happening on the demand side of energy – and to see it happening right here in Houston.

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.
