Japanese HVAC company Daikin Industries has completed a nearly one-megawatt solar power plant at its Daikin Comfort Technologies North America campus southeast of Waller.

Daikin says the new plant at its 4.2 million-square-foot Daikin Texas Technology Park will eliminate an estimated 845 metric tons of carbon emissions each year. The park houses the largest HVAC factory in North America.

“Daikin’s unwavering commitment to innovation drives us to continually perfect the air we share. With the launch of this solar project, we’re one step closer to being a net-zero CO2 emission factory by 2030,” Nathan Walker, senior vice president of environmental business development of locally based Daikin Comfort Technologies North America, said in a release. “This installation is a significant step in reducing our carbon footprint and underscores our commitment to energy efficiency, sustainability, and environmental stewardship.”

Solar power from the new facility will power the Daikin campus’ central chiller plant, which circulates about 125,000 gallons of chilled water annually and 75,000 gallons of hot water in the winter. Also, the solar setup is designed to connect to the electric grid that serves the campus. About 10,000 people work at the campus.

Daikin, a Fortune 1000 company, may not have been a familiar name to some Houstonians until January, when it took over the naming rights for the Houston Astros’ stadium. The naming rights agreement for Daikin Park, formerly Minute Maid Park, expires during the Astros’ 2039 season. The stadium had been named Minute Maid Park since 2002.

“The Astros are the pride of Houston, an organization that has built resiliency in hard times, and have succeeded to be a winning team. The coming together of both our organizations is a symbol of our love for our hometown and the communities of the Greater Houston area,” Takayuki “Taka” Inoue, executive vice president and chief sales and marketing officer at Daikin Comfort Technologies North America, said in November.

Global industrial company Daikin makes deal with Houston Astros on stadium rename

big deal

The Houston Astros' home will get a new name on Jan. 1, becoming Daikin Park under an agreement through the 2039 season the team announced Monday.

The stadium opened as Enron Field in 2000 as part of a 30-year, $100 million agreement but the name was removed in March 2002 following Enron Corp.'s bankruptcy filing and the ballpark briefly became Astros Field.

It was renamed Minute Maid Park in June 2002 as part of a deal with The Minute Maid Co., a Houston-based subsidiary of The Coca-Cola Co. Then-Astros owner Drayton McLane said at the time the agreement was for 28 years and for more than $100 million.

The new deal is with Daikin Comfort Technologies North America Inc., a subsidiary of Daikin Industries Ltd., which is based in Japan and is a leading air conditioning company.

Minute Maid will remain an Astros partner through 2029, the team said.

In August, Daikin, which has its 4.2 million-square-foot Daikin Texas Technology Park in Waller, Texas, partnered with the city of Houston to provide advanced air conditioning and heating solutions to help homeowners with energy efficiency and general comfort. The company pledged install up to 30 horizontal discharge inverter FIT heat pump units over the next three years.

A Japanese air conditioner manufacturer has teamed up with the city of Houston on an energy efficiency initiative.

Daikin Comfort Technologies, which has its 4.2 million-square-foot Daikin Texas Technology Park in Waller, Texas, has partnered with the city of Houston to provide advanced air conditioning and heating solutions to help homeowners with energy efficiency and general comfort.

The company will install up to 30 horizontal discharge inverter FIT heat pump units over the next three years. The units will be provided to low-to-moderate-income households, which will include seniors over the age of 62, and homes renovated through the Housing and Community Development Department’s Home Repair Program. The new units will offer internet connectivity for remote monitoring and control. The installations align with Houston's Home Repair Program reconstruction plans.

“We are proud to partner with the City of Houston to launch this program that can directly advance their vision for decarbonization and increasing grid resiliency through higher efficiency,” CEO Satoru Akama says in a news release. “Through this program, Homeowners will have a premium system that will not only provide comfort but save on their monthly bills and do so in a way that lowers site emissions of CO2 compared to traditional, non-inverter systems. At Daikin, we are focused on changing the culture of air conditioning in North America and are looking forward to having a direct impact in our hometown.”

The initiative coincides with the company’s 100th year anniversary and National Air Condition Appreciation Days, which was coined by Mayor John Whitmire on August 13. Air Conditioning Appreciation Days ran from July 3 until August 15.

“The city thanks Daikin for this collaboration. Houstonians, especially seniors, (that) must have the resources to stay comfortable during extreme temperatures,” Whitmire adds. “This partnership reflects our dedication to caring for the well-being of our community.”

Awareness is part of the appreciation days, as Daikin recommends homeowners and facilities to clean filters, schedule maintenance checkups and look at ways to lower energy use.

“Through these new energy-efficient solutions, Daikin is helping the city promote a more sustainable environment for our community, and we are thankful for their example of how public-private partnerships can make a positive difference in society,” Houston Council Member Sallie Alcorn says in a news release.

Houston scientists unveil faster, low-energy method to recycle lithium-ion batteries

Battery breakthrough

Rice University researchers have uncovered a more energy-efficient and faster way to recycle critical minerals from used lithium-ion batteries.

Traditional methods rely on high heat, long processing times and harsh chemicals to recover a small fraction of critical materials from batteries used in everything from smartphones to electric vehicles. However, the team from Rice's Department of Materials Science and Nanoengineering developed a process that uses a water-based solution containing amino chlorides to extract more metals in less time

The team published the findings in a recent edition of the scientific journal Small.

Simon King, a sophomore studying chemical and biomolecular engineering who completed this work as a summer research fellow at the Rice Advanced Materials Institute, served as first author of the study. He worked with corresponding authors Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering, and Sohini Bhattacharyya, a research scientist in Ajayan’s lab.

By using a hydroxylammonium chloride (HACI) solution, the team achieved roughly 65 percent extraction of key battery metals in just one minute at room temperature, according to the study. The efficiencies grew to roughly 75 percent for several metals under longer processing times.

“We were surprised by just how fast the reaction occurs, especially without the involvement of high temperatures,” King said in a news release. “Within the first minute, we’re already seeing the majority of the metal extraction take place.”

By not requiring high temperatures or long reaction times, Rice predicts the process could have a major impact on cost and the environmental impact of lithium battery recycling. Additionally, the water-based HACI solution makes waste handling easier and lowers certain environmental risks.

In addition to extracting the materials, the team went on to demonstrate that the recovered metals could be recycled and reprocessed into new battery materials.

“A big advantage of this system is that it works under relatively mild conditions,” Ajayan added in the release. “That opens the door to more sustainable and scalable recycling technologies.”
