Houston-based energy industry analyst Clay Seigle has joined the Center for Strategic and International Studies (CSIS) as a senior fellow and the James R. Schlesinger Chair for Energy and Geopolitics in the Energy Security and Climate Change (ESCC) Program.

“I’m honored to join CSIS as Senior Fellow and the James R. Schlesinger Chair for Energy and Geopolitics,” Seigle said in a news release. “In a time of unprecedented change in global energy markets, CSIS is uniquely positioned to advance policies that promote security, resilience, and innovation. I look forward to working alongside Joseph (Majkut, director of the Energy Security and Climate Change Program) and our outstanding colleagues to deliver impactful research and expand CSIS’s engagement with stakeholders in Washington and Houston.”

Seigle most recently served as director of Global Oil at Rapidan Energy Group, a D.C.-based independent energy analysis firm. At REG, he provided expert analysis on oil market forecasts and geopolitical scenarios to government and private sector stakeholders. He has also held leadership and analysis roles at organizations including Cambridge Energy Research Associates (CERA), the U.S. Department of Energy, Enron and others. He specializes in market intelligence, global energy security and political risk.

Seigle is a board member of the Houston Committee on Foreign Relations and chairs its Finance Committee. He is also a former vice president of the U.S. Association for Energy Economics. He holds a master’s degree in international relations (Middle East) and economics from Johns Hopkins University’s School of Advanced International Studies and a bachelor’s degree in government from the University of Texas at Austin.

The ESCC’s work has focused on developing diverse energy resources for the U.S. and providing leaders with insights on how to address challenges like climate change. According to CSIS, the ESCC program recently launched an Economic Security and Technology Department that aims to tackle topics like using artificial intelligence to maintain energy security.

“Our longstanding energy program is a centerpiece of our department’s work on the drivers of U.S. economic security in an era of technology competition,” Navin Girishankar, president of the CSIS Economic Security and Technology Department, said in a news release. “Clay’s deep understanding of energy markets and energy security will be an asset to CSIS leadership on these issues in the years to come. We are delighted that he is joining our team at a critical time for U.S. economic security policy.”

A new study by researchers from Rice University’s Department of Materials Science and NanoEngineering, Baylor University and the Indian Institute of Science Education and Research Thiruvananthapuram has introduced a solution that could help develop more affordable and sustainable sodium-ion batteries.

The findings were recently published in the journal Advanced Functional Materials.

The team worked with tiny cone- and disc-shaped carbon materials from oil and gas industry byproducts with a pure graphitic structure. The forms allow for more efficient energy storage with larger sodium and potassium ions, which is a challenge for anodes in battery research. Sodium and potassium are more widely available and cheaper than lithium.

“For years, we’ve known that sodium and potassium are attractive alternatives to lithium,” Pulickel Ajayan, the Benjamin M. and Mary Greenwood Anderson Professor of Engineering at Rice, said in a news release. “But the challenge has always been finding carbon-based anode materials that can store these larger ions efficiently.”

Lithium-ion batteries traditionally rely on graphite as an anode material. However, traditional graphite structures cannot efficiently store sodium or potassium energy, since the atoms are too big and interactions become too complex to slide in and out of graphite’s layers. The cone and disc structures “offer curvature and spacing that welcome sodium and potassium ions without the need for chemical doping (the process of intentionally adding small amounts of specific atoms or molecules to change its properties) or other artificial modifications,” according to the study.

“This is one of the first clear demonstrations of sodium-ion intercalation in pure graphitic materials with such stability,” Atin Pramanik, first author of the study and a postdoctoral associate in Ajayan’s lab, said in the release. “It challenges the belief that pure graphite can’t work with sodium.”

In lab tests, the carbon cones and discs stored about 230 milliamp-hours of charge per gram (mAh/g) by using sodium ions. They still held 151 mAh/g even after 2,000 fast charging cycles. They also worked with potassium-ion batteries.

“We believe this discovery opens up a new design space for battery anodes,” Ajayan added in the release. “Instead of changing the chemistry, we’re changing the shape, and that’s proving to be just as interesting.”
