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.

Rice University spinout lands $500K NSF grant to boost chip sustainability

cooler computing

HEXAspec, a spinout from Rice University's Liu Idea Lab for Innovation and Entrepreneurship, was recently awarded a $500,000 National Science Foundation Partnership for Innovation grant.

The team says it will use the funding to continue enhancing semiconductor chips’ thermal conductivity to boost computing power. According to a release from Rice, HEXAspec has developed breakthrough inorganic fillers that allow graphic processing units (GPUs) to use less water and electricity and generate less heat.

The technology has major implications for the future of computing with AI sustainably.

“With the huge scale of investment in new computing infrastructure, the problem of managing the heat produced by these GPUs and semiconductors has grown exponentially. We’re excited to use this award to further our material to meet the needs of existing and emerging industry partners and unlock a new era of computing,” HEXAspec co-founder Tianshu Zhai said in the release.

HEXAspec was founded by Zhai and Chen-Yang Lin, who both participated in the Rice Innovation Fellows program. A third co-founder, Jing Zhang, also worked as a postdoctoral researcher and a research scientist at Rice, according to HEXAspec's website.

The HEXASpec team won the Liu Idea Lab for Innovation and Entrepreneurship's H. Albert Napier Rice Launch Challenge in 2024. More recently, it also won this year's Energy Venture Day and Pitch Competition during CERAWeek in the TEX-E student track, taking home $25,000.

"The grant from the NSF is a game-changer, accelerating the path to market for this transformative technology," Kyle Judah, executive director of Lilie, added in the release.

Rice research team's study keeps CO2-to-fuel devices running 50 times longer

new findings

In a new study published in the journal Science, a team of Rice University researchers shared findings on how acid bubbles can improve the stability of electrochemical devices that convert carbon dioxide into useful fuels and chemicals.

The team led by Rice associate professor Hoatian Wang addressed an issue in the performance and stability of CO2 reduction systems. The gas flow channels in the systems often clog due to salt buildup, reducing efficiency and causing the devices to fail prematurely after about 80 hours of operation.

“Salt precipitation blocks CO2 transport and floods the gas diffusion electrode, which leads to performance failure,” Wang said in a news release. “This typically happens within a few hundred hours, which is far from commercial viability.”

By using an acid-humidified CO2 technique, the team was able to extend the operational life of a CO2 reduction system more than 50-fold, demonstrating more than 4,500 hours of stable operation in a scaled-up reactor.

The Rice team made a simple swap with a significant impact. Instead of using water to humidify the CO2 gas input into the reactor, the team bubbled the gas through an acid solution such as hydrochloric, formic or acetic acid. This process made more soluble salt formations that did not crystallize or block the channels.

The process has major implications for an emerging green technology known as electrochemical CO2 reduction, or CO2RR, that transforms climate-warming CO2 into products like carbon monoxide, ethylene, or alcohols. The products can be further refined into fuels or feedstocks.

“Using the traditional method of water-humidified CO2 could lead to salt formation in the cathode gas flow channels,” Shaoyun Hao, postdoctoral research associate in chemical and biomolecular engineering at Rice and co-first author, explained in the news release. “We hypothesized — and confirmed — that acid vapor could dissolve the salt and convert the low solubility KHCO3 into salt with higher solubility, thus shifting the solubility balance just enough to avoid clogging without affecting catalyst performance.”

The Rice team believes the work can lead to more scalable CO2 electrolyzers, which is vital if the technology is to be deployed at industrial scales as part of carbon capture and utilization strategies. Since the approach itself is relatively simple, it could lead to a more cost-effective and efficient solution. It also worked well with multiple catalyst types, including zinc oxide, copper oxide and bismuth oxide, which are allo used to target different CO2RR products.

“Our method addresses a long-standing obstacle with a low-cost, easily implementable solution,” Ahmad Elgazzar, co-first author and graduate student in chemical and biomolecular engineering at Rice, added in the release. “It’s a step toward making carbon utilization technologies more commercially viable and more sustainable.”

A team led by Wang and in collaboration with researchers from the University of Houston also shared findings on salt precipitation buildup and CO2RR in a recent edition of the journal Nature Energy. Read more here.
