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.

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.
