A Houston engineering solutions company has teamed up with a company to advance zero-emission lithium extraction technology.

KBR (NYSE: KBR) has signed an alliance agreement with France-based GeoLith SAS to offer its advanced Direct Lithium Extraction (DLE) technology, Li-Capt, which allows for zero-emission lithium extraction from untapped sources like oil well brines and geothermal.

"We are excited to collaborate with GeoLith to pioneer advancements in accessing currently untapped sources of lithium to meet the world's increasing lithium-ion battery demand,” KBR President Jay Ibrahim says in a news release. “This alliance supports the global transition towards electrification and reinforces our commitment to a net-zero carbon future. As a world leader in evaporation and crystallization technologies, KBR is well positioned to provide end-to-end solutions essential to the development of sustainable mobility."

Per the agreement, KBR will serve as the exclusive global licensor of GeoLith's Li-Capt technology. The Li-Capt tech helps produce pure lithium concentrate and is adaptable to brine compositions and extraction sources. KBR already boasts an existing suite of battery material technologies like PureLiSM, which is a high purity lithium production technology. The combination of the two technologies aim to provide clients with solutions to produce battery-grade lithium carbonate or lithium hydroxide monohydrate. Those are key components for advanced batteries in electric vehicles.

“The transition to electrification requires strong partnerships across the value chain, and we are proud to work with KBR to advance and commercialize our technology on a global scale," Jean-Philippe Gibaud, CEO of GeoLith SAS, says in the release. "Our Li-Capt technology ensures zero-emission lithium extraction, enabling the production of lithium concentrates from a process technology that achieves unparalleled levels of extraction efficiency and lithium selectivity."

KBR was recently awarded a contract by First State Hydrogen, which is building an electrolysis-powered green hydrogen production project. The study is part of First State Hydrogen's plan to provide clean energy to Delaware and the U.S. mid-Atlantic region. Additionally, KBR’s K-GreeN technology has been selected by a group of organizations — including Lotte Chemical, KNOC (Korea National Oil Corp), and Samsung Engineering — for the Sarawak, Malaysia-based H2biscus green ammonia project being developed by Lotte Chemical. The K-GreeN is a proprietary green ammonia development process. According to the company, KBR has licensed, engineered, or constructed over 250 ammonia plants since its founding in 1943.

Houston researchers make headway on developing low-cost sodium-ion batteries

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.”
