A Houston school is cashing in a major gift from a local energy company in order to support the industry's future workforce, research, and more.

The University of Houston Energy Transition Institute received a $100,000 grant from the Baker Hughes Foundation this week, which will work towards the ETI’s goals to support workforce development programs, and environmental justice research.

The program addresses the impact of energy transition solutions in geographical areas most-affected by environmental impacts.

“We are proud to support the University of Houston in its environmental justice research and workforce development programs; at Baker Hughes, we strive to take energy forward, and are committed to a fair and just energy transition,” says Chief Sustainability Officer Allyson Book in a news release. “Novel educational approaches centered around social, climate and environmental justice are crucial to creating a sustainable future for generations to come.”

The grant aims to help ETI in analyzing environmental footprints of energy use processes, energy use processes, impact on health, and emissions, as well as support the university’s Energy Scholars Program, which focuses on research programs on carbon management, hydrogen, and circular plastics for undergraduate students.The donation also supports Baker Hughes’ work with the United Nations’ Sustainable Development Goals (SDGs) that work to ensure “inclusive and equitable quality education for all.”

“We look forward to working with the Baker Hughes Foundation to address grand challenges in energy and chemicals and create a sustainable and equitable future for all,” says Ramanan Krishnamoorti, vice president of energy and innovation at UH.

ETI launched a year ago through a $10 million grant from Shell USA Inc. and Shell Global Solutions (US) Inc., and is led by Joe Powell, who opted to take the helm of the program over retiring, telling EnergyCapital that it was an opportunity he couldn't pass up.

UH has announced a central campus innovation hub that will house UH's programs for STEM, social sciences, business and arts. Slated to open in 2025, the 70,000 square foot hub will house a makerspace, the Cyvia and Melvyn Wolff Center for Entrepreneurship, the Energy Transition Institute, innovation programs, and Presidential Frontier Faculty labs and offices.

“The University of Houston aims to transform lives and communities through education, research, innovation and service in a real-world setting," Krishnamoorti says in a news release. “I am confident that working together we will make a greater impact.”

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.
