Houston carbon storage solutions company names new energy transition leader at pivotal time of growth

ready to grow

Graham Payne sees a bright future for the multibillion-dollar energy transition economy in Houston.

“It’s been said that Houston is poised, like no other city, to lead the energy transition. And I’d have to agree, because we have all the requisite natural resources, industry, and talent,” says Payne, the new director of energy transition at Houston-based carbon capture, utilization, and storage (CCUS) company Caliche Development Partners II.

Caliche and other Houston-based energy transition companies secured $6.1 billion in private funding last year, up 62 percent from 2022, according to the Greater Houston Partnership.

“As the region positions itself as the leader in the global energy transition, Houston has seen constant growth in annual energy transition investments over the last five years,” the partnership says.

Payne, a geologist, comes to Caliche after holding roles at Battelle and Schlumberger, among other companies. Houston-based Sudduth Search recruited Payne for the Caliche job.

In his new position, Payne is overseeing permitting and completion of a leased 4,000-acre site in Beaumont for sequestration of carbon dioxide. Payne will also work on current and potential gas storage projects, which he says “will continue to play an important role in the energy mix.”

At previous employers, Payne has tackled various aspects of CCUS.

“The really enticing part about this job is the chance to put it all together, and then operate a full-scale operation,” he says. “I want this technology to move firmly out of the research phase and start making a measurable difference against climate change.”

Payne says Caliche is capable of successfully straddling the worlds of CCUS, natural gas storage, and industrial gas storage. The Beaumont project alone will be able sequester at least 30 million metric tons of carbon, a Caliche estimate indicates.

In November, Caliche announced the acquisition of its first CCUS assets, Golden Triangle Storage and Central Valley Gas Storage, following a $268 million infusion of capital from Orion Infrastructure Capital and GCM Grosvenor. Orion maintains offices in Houston, New York City, and London. GCM is based in Chicago.

The Golden Triangle and Central Valley deals were valued at a combined $186 million.

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.
