Researchers at the University of Houston have unlocked a new way to use crystals to safely dispose of radioactive waste.

The team of UH researchers published a paper in Cell Reports Physical Science this month detailing their discovery of how to use molecular crystals to capture large quantities of iodine, one of the most common products of radioactive fission, which is used to create nuclear energy.

According to a statement from UH, these molecular crystals are based on cyclotetrabenzil hydrazones. Ognjen Miljanic, professor of chemistry and author of the paper, and his team have created the organic molecules containing only carbon, hydrogen and oxygen atoms, which create ring-like crystals with eight smaller offshoots, earning them the nickname "The Octopus."

The discovery was made by Alexandra Robles, the first author of the study and a former doctoral student in Miljanic’s lab.

The crystals have an uptake capacity similar to that of porous metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), which traditionally have been considered the “pinnacle of iodine capture materials," according to UH. They allow iodine to be moved from one area to another, are reusable and can be produced using commercially available chemicals for about $1 per gram in an academic lab.

“They are quite easy to make and can be produced at a large scale from relatively inexpensive materials without any special protective atmosphere,” Miljanic said in a statement.

The team also believes the crystals can be used to capture additional elements like carbon dioxide.

“This is a type of simple molecule that can do all sorts of different things depending on how we integrate it with the rest of any given system,” Miljanic continued. “So, we’re pursuing all those applications as well.”

Next up, Miljanic is looking to find a partner that will help the team explore practical applications and commercial aspects.

UH has been making net-zero news lately. A team of students from UH placed in the top three teams in a national competition for the Department of Energy earlier this summer. The college also shared details about its forthcoming innovation hub, which will house UH's Energy Transition Institute, as well as other centers and programs.

Joseph Powell, founding director of UH's Energy Transition Institute, sat down with EnergyCapitalHTX last week to talk about UH's vision for the organization.

Energy AI company opens first U.S. office in Houston after Halliburton deal

houston expansion

Building on its partnership with Houston-based oilfield services provider Halliburton, energy-sector AI company Shape Digital recently opened an office at The Ion. It’s the company’s first U.S. location.

Shape Digital’s workforce in Houston includes employees specializing in tech support, business development and client services. The company’s local hiring projections and headcount weren’t available. The new office will be located within Industrious at the Ion, according to Rice Alliance.

A key driver of the new Houston office: The company forecasts North America will account for more than 20 percent of its business in 2027.

“North America is a critical market for industrial innovation, and Houston sits at the center of companies driving that progress,” Caio Sene, vice president of client services at Shape Digital, said in a release. “Growing our presence here allows us to work alongside operators as they look for practical ways to turn existing operational data into clear recommendations for what to do next.”

Shape Digital, which also has offices in Singapore and Brazil, develops decision-making platforms for the oil and gas sector.

The Ion District office gives Shape Digital a presence close to Halliburton’s headquarters. In May, the two companies forged a partnership to combine Halliburton’s Digital Field Solverdecision-making system with Shape Digital’s AI portfolio.

Shape Digital layers AI software atop existing operations data rather than replacing legacy systems or adding new software.

The company’s suite of AI agents draws on more than 200 operations-monitoring algorithms, continually learning from company and industry data. The suite comprises four products: Shape Aura, Shape Lighthouse, Shape Lumen and Shape Reef.

Shape Digital says that by working with a customer’s existing operations data, it can deliver ROI in less than two months without any additional investment in equipment or infrastructure.

The company is a 2021 spinoff of Japan-based Modec. Modec builds, owns, and operates floating offshore oil and gas production facilities. Its Modec America subsidiary is based in Houston.

Houston energy startup names former Cheniere execs to C-suite

new leaders

Houston-based energy infrastructure startup Joulent has brought aboard a new chief financial officer and new chief operating officer—both former executives at Houston-based Cheniere Energy.

The C-suite moves come three months after Joulent raised $1.75 billion from National Grid Ventures.

Michael Wortley joins Joulent as co-president and CFO. Wortley most recently was executive vice president and CFO at Cheniere, an LNG producer and exporter.

In conjunction with Wortley’s hiring, Brian Boland, who was Joulent’s interim CFO, has been named executive vice president, chief investment officer, and head of strategy.

Corey Grindal comes to Joulent as co-president and COO. Grindal most recently was executive vice president and COO at Cheniere.

“As Joulent evolves to meet the growing demand for power infrastructure, our expanded leadership team will help ensure we continue delivering the execution certainty our customers, partners, and investors expect,” Chris James, Joulent’s founder and CEO, said in a press release.

“Corey and Michael are accomplished operators with exceptional records of building and leading world-class energy infrastructure businesses, where they have embedded a culture defined by operational excellence and disciplined execution,” James added.

Joulet builds dedicated power-generating facilities that feed directly into data centers and other power-dependent facilities. This eliminates the need for companies to draw power from grids.

“With an initial multi-gigawatt development portfolio and strategic partnerships across the energy, infrastructure, and data center ecosystem, Joulent is helping remove power constraints to enable the next chapter of American innovation and U.S. reindustrialization,” the company says.

The $1.75 billion minority investment from National Grid Ventures complements Joulent’s existing partnerships.

Joulent, founded in 2023, emerged from stealth mode this summer. The company was founded by investment firm Engine No. 1.

Joulent’s first project, the Project Kilby natural gas facility in West Texas, will be co-located with a Microsoft data center. It’ll deliver about 2.67 gigawatts of power under a 20-year deal between Microsoft and Energy Forge One, a 50/50 joint venture between Chevron and Joulent.

Lithium refiner expands into Houston with new Energy Corridor office

new to hou

Battery-grade lithium carbonate manufacturer Stardust Power has expanded into Houston’s Energy Corridor, the company tells Energy Capital.

The company’s new office will serve as a project execution hub to support operations and planning for the company’s forthcoming lithium refinery in Muskogee, Oklahoma, according to a news release. The Greenwich, Connecticut-based, publicly traded company says the facility will be one of the largest lithium refining operations in the United States. The refinery is expected to have production capacity of up to 50,000 metric tons per year and seeks to address the critical shortage of U.S. lithium refining capacity.

Battery-grade lithium carbonate is commonly used in electric vehicle batteries and energy storage systems.

The company says it chose Houston as the location for its new execution hub for its rich history of expertise in engineering, a robust energy infrastructure ecosystem, and access to a leading talent pool for engineering, procurement and construction professionals. The Houston project hub will work closely with the company’s existing office in Oklahoma City.

“The Houston office strengthens our operational footprint at a critical phase of development,” Chris Celano, COO of Stardust Power, said in the release. “By building out a dedicated project management hub in one of the most experienced energy markets in the world, we are positioning the Company for execution as we advance the Muskogee refinery.”

Currently, the Houston office plans to accommodate a workforce of about 20 people with the possibility to add staff upon reaching project milestones, according to a representative from the company.

“This expansion reflects our commitment to deliver domestic, battery-grade lithium that supports U.S. energy security and industrial growth,” Celano added in the release.

In August, Stardust Power secured an offtake agreement to supply up to 20,000 metric tons of battery-grade lithium carbonate by 2030 from the Muskogee, Oklahoma, refinery to New York-based battery technology company Charge CCCV. Stardust reports that the deal adds to a separate non-binding agreement for up to 25,000 metric tons annually for 10 years with an undisclosed global trading company.
