Researchers at Rice University have developed a catalyst that could render steam methane reforming, or SMR, entirely emission-free by using light rather than heat to drive the reaction.

The researchers believe the work could prove to be a breakthrough for extending catalyst lifetimes. This will improve efficiencies and reduce costs for a number of industrial processes that are affected by a form of carbon buildup that can deactivate catalysts called coking.

The new copper-rhodium photocatalyst uses an antenna-reactor design. When it is exposed to a specific wavelength of light it breaks down methane and water vapor without external heating into hydrogen and carbon monoxide. The importance of this is it is a chemical industry feedstock that is not a greenhouse gas. Rice’s work also shows that the antenna-reactor technology can overcome catalyst deactivation due to oxidation and coking by employing hot carriers to remove oxygen species and carbon deposits, which effectively regenerates the catalyst with light.

The new SMR reaction pathway build off a 2011 discovery from Peter Nordlander, Rice’s Wiess Chair and Professor of Physics and Astronomy and professor of electrical and computer engineering and materials science and nanoengineering, and Naomi Halas. They are the authors on the study about the research that was published in Nature Catalysis. The study showed that the collective oscillations of electrons that occur when metal nanoparticles are exposed to light can emit “hot carriers” or high-energy electrons and holes that can be used to drive chemical reactions.

“This is one of our most impactful findings so far, because it offers an improved alternative to what is arguably the most important chemical reaction for modern society,” Norlander says in a news release.

The research was supported by Robert A. Welch Foundation (C-1220, C-1222) and the Air Force Office of Scientific Research (FA9550-15-1-0022) with the Shared Equipment Authority at Rice providing data analysis support.

“This research showcases the potential for innovative photochemistry to reshape critical industrial processes, moving us closer to an environmentally sustainable energy future,” Halas adds.

Hydrogen has been studied as it could assist with the transition to a sustainable energy ecosystem, but the chemical process responsible for more than half of the current global hydrogen production is a substantial source of greenhouse gas emissions.Hydrogen is produced in large facilities that require the gas to be transported to its point of use. Light-driven SMR allows for on-demand hydrogen generation,which researchers believe is a key benefit for use in mobility-related applications like hydrogen fueling stations or and possibly vehicles.

Investment bank opens new Houston office focused on energy sector

Investment bank Cohen & Co. Capital Markets has opened a Houston office to serve as the hub of its energy advisory business and has tapped investment banking veteran Rahul Jasuja as the office’s leader.

Jasuja joined Cohen & Co. Capital Markets, a subsidiary of financial services company Cohen & Co., as managing director, and head of energy and energy transition investment banking. Cohen’s capital markets arm closed $44 billion worth of deals last year.

Jasuja previously worked at energy-focused Houston investment bank Mast Capital Advisors, where he was managing director of investment banking. Before Mast Capital, Jasuja was director of energy investment banking in the Houston office of Wells Fargo Securities.

“Meeting rising [energy] demand will require disciplined capital allocation across traditional energy, sustainable fuels, and firm, dispatchable solutions such as nuclear and geothermal,” Jasuja said in a news release. “Houston remains the center of gravity where capital, operating expertise, and execution come together to make that transition investable.”

The Houston office will focus on four energy verticals:

  • Energy systems such as nuclear and geothermal
  • Energy supply chains
  • Energy-transition fuel and technology
  • Traditional energy
“We are making a committed investment in Houston because we believe the infrastructure powering AI, defense, and energy transition — from nuclear to rare-earth technology — represents the next secular cycle of value creation,” Jerry Serowik, head of Cohen & Co. Capital Markets, added in the release.

MD Anderson makes AI partnership to advance precision oncology

AI Oncology

Few experts will disagree that data-driven medicine is one of the most certain ways forward for our health. However, actually adopting it comes at a steep curve. But what if using the technology were democratized?

This is the question that SOPHiA GENETICS has been seeking to answer since 2011 with its universal AI platform, SOPHiA DDM. The cloud-native system analyzes and interprets complex health care data across technologies and institutions, allowing hospitals and clinicians to gain clinically actionable insights faster and at scale.

The University of Texas MD Anderson Cancer Center has just announced its official collaboration with SOPHiA GENETICS to accelerate breakthroughs in precision oncology. Together, they are developing a novel sequencing oncology test, as well as creating several programs targeted at the research and development of additional technology.

That technology will allow the hospital to develop new ways to chart the growth and changes of tumors in real time, pick the best clinical trials and medications for patients and make genomic testing more reliable. Shashikant Kulkarni, deputy division head for Molecular Pathology, and Dr. J. Bryan, assistant professor, will lead the collaboration on MD Anderson’s end.

“Cancer research has evolved rapidly, and we have more health data available than ever before. Our collaboration with SOPHiA GENETICS reflects how our lab is evolving and integrating advanced analytics and AI to better interpret complex molecular information,” Dr. Donna Hansel, division head of Pathology and Laboratory Medicine at MD Anderson, said in a press release. “This collaboration will expand our ability to translate high-dimensional data into insights that can meaningfully advance research and precision oncology.”

SOPHiA GENETICS is based in Switzerland and France, and has its U.S. offices in Boston.

“This collaboration with MD Anderson amplifies our shared ambition to push the boundaries of what is possible in cancer research,” Dr. Philippe Menu, chief product officer and chief medical officer at SOPHiA GENETICS, added in the release. “With SOPHiA DDM as a unifying analytical layer, we are enabling new discoveries, accelerating breakthroughs in precision oncology and, most importantly, enabling patients around the globe to benefit from these innovations by bringing leading technologies to all geographies quickly and at scale.”

Houston company plans lunar mission to test clean energy resource

Houston-based natural resource and lunar development company Black Moon Energy Corporation (BMEC) announced that it is planning a robotic mission to the surface of the moon within the next five years.

The company has engaged NASA’s Jet Propulsion Laboratory (JPL) and Caltech to carry out the mission’s robotic systems, scientific instrumentation, data acquisition and mission operations. Black Moon will lead mission management, resource-assessment strategy and large-scale operations planning.

The goal of the year-long expedition will be to gather data and perform operations to determine the feasibility of a lunar Helium-3 supply chain. Helium-3 is abundant on the surface of the moon, but extremely rare on Earth. BMEC believes it could be a solution to the world's accelerating energy challenges.

Helium-3 fusion releases 4 million times more energy than the combustion of fossil fuels and four times more energy than traditional nuclear fission in a “clean” manner with no primary radioactive products or environmental issues, according to BMEC. Additionally, the company estimates that there is enough lunar Helium-3 to power humanity for thousands of years.

"By combining Black Moon's expertise in resource development with JPL and Caltech's renowned scientific and engineering capabilities, we are building the knowledge base required to power a new era of clean, abundant, and affordable energy for the entire planet," David Warden, CEO of BMEC, said in a news release.

The company says that information gathered from the planned lunar mission will support potential applications in fusion power generation, national security systems, quantum computing, radiation detection, medical imaging and cryogenic technologies.

Black Moon Energy was founded in 2022 by David Warden, Leroy Chiao, Peter Jones and Dan Warden. Chiao served as a NASA astronaut for 15 years. The other founders have held positions at Rice University, Schlumberger, BP and other major energy space organizations.
