Spring-headquartered ExxonMobil Corp. has announced a new MOU for an offtake agreement for up to 100,000 metric tons of lithium carbonate.

The agreement is with LG Chem, which is building its cathode plant in Tennessee and expects it to be the largest of its kind in the country. The project broke ground a year ago and expects an annual production capacity of 60,000 tons. The lithium will be supplied by ExxonMobil.

“America needs secure domestic supply of critical minerals like lithium,” Dan Ammann, president of ExxonMobil Low Carbon Solutions, says in a news release. “ExxonMobil is proud to lead the way in establishing domestic lithium production, creating jobs, driving economic growth, and enhancing energy security here in the United States.”

The industry currently has a lithium supply shortage due to the material's use in electric vehicle batteries and the fact that most of production happens overseas.

“Building a lithium supply chain with ExxonMobil, one of the world’s largest energy companies, holds great significance,” Shin Hak-cheol, CEO of LG Chem, adds. “We will continue to strengthen LG Chem’s competitiveness in the global supply chain for critical minerals.”

Per the release, the final investment decision is still pending.

Earlier this year, Exxon entered into another energy transition partnership, teaming up with Japan’s Mitsubishi to potentially produce low-carbon ammonia and nearly carbon-free hydrogen at ExxonMobil’s facility in Baytown.

Last month, the company announced it had signed the biggest offshore carbon dioxide storage lease in the U.S. ExxonMobil says the more than 271,000-acre site, being leased from the Texas General Land Office, complements the onshore CO2 storage portfolio that it’s assembling.

New CEO named to batteries co., to build out direct lithium extraction operations globally

at the helm

A Houston- and Vancouver-based battery materials company has named a new CEO, effective later this summer.

International Battery Metals (IBAT) announced the appointment of Iris Jancik as CEO. She will focus on expanding commercial deployment of IBAT's patented modular direct lithium extraction (DLE) plants, and begin in the role in mid-August.

Currently, IBAT is commissioning the DLE plant with an initial design capacity of 5,000 metric tons a year. The plant expects to begin lithium production in June. The plant will process brine produced from lithium-containing waste-magnesium salts, and the lithium chloride product will provide feed for high-purity lithium carbonate production by US Mag.

The plant is the first commercial DLE plant in North America and the first modular DLE plant in the world. IBAT also recently announced the installation of its first commercial lithium production plant, which is co-located at US Magnesium's (US Mag) operations outside Salt Lake City, Utah.

Jancik served as CEO of IDE Americas, a subsidiary of IDE Technologies, which is a global desalination and water treatment solutions company prior to joining IBAT. She holds an M.B.A. in international business from Texas A&M University, and brings expertise as an engineer with extensive global contracting and management experience.

"Iris brings deep expertise in water infrastructure, which is core to our DLE water-recycling process, and the requisite global commercial chops to build on IBAT's momentum," John Burba, CTO and director of International Battery Metals, says in a news release. "I expect IBAT to take on new frontiers for growth with Iris at the helm and look forward to collaborating with her."

Jancik will be taking over for the person credited with accelerating IBAT's technology to its first commercial phase , Garry Flowers, who joined IBAT for a two-year period, starting as president in July 2022 and then named CEO in December 2022.

According to IBAT, IBAT's modular lithium extraction plant has been independently verified to extract more than 97% lithium from brine. Lithium production is rising to reach approximately 180,000 metric tons in 2023 with approximately 22,000 metric tons coming from an established DLE project in Argentina.

"IBAT's proprietary commercialized DLE technology is proven, ready to push-start a US lithium industry, and revolutionize global production, making this a prime time to join the organization," Jancik adds. "Burgeoning battery demand requires a wholesale change in how lithium is produced, and IBAT delivers the right combination of efficiency, sustainability and scalability to reach new heights.”

Houston maritime startup raises $43M to electrify cargo vessels

A Houston-based maritime technology company that is working to reduce emissions in the cargo and shipping industry has raised VC funding and opened a new Houston headquarters.

Fleetzero announced that it closed a $43 million Series A financing round this month led by Obvious Ventures with participation from Maersk Growth, Breakthrough Energy Ventures, 8090 Industries, Y Combinator, Shorewind, Benson Capital and others. The funding will go toward expanding manufacturing of its Leviathan hybrid and electric marine propulsion system, according to a news release.

The technology is optimized for high-energy and zero-emission operation of large vessels. It uses EV technology but is built for maritime environments and can be used on new or existing ships with hybrid or all-electric functions, according to Fleetzero's website. The propulsion system was retrofitted and tested on Fleetzero’s test ship, the Pacific Joule, and has been deployed globally on commercial vessels.

Fleetzero is also developing unmanned cargo vessel technology.

"Fleetzero is making robotic ships a reality today. The team is moving us from dirty, dangerous, and expensive to clean, safe, and cost-effective. It's like watching the future today," Andrew Beebe, managing director at Obvious Ventures, said in the news release. "We backed the team because they are mariners and engineers, know the industry deeply, and are scaling with real ships and customers, not just renderings."

Fleetzero also announced that it has opened a new manufacturing and research and development facility, which will serve as the company's new headquarters. The facility features a marine robotics and autonomy lab, a marine propulsion R&D center and a production line with a capacity of 300 megawatt-hours per year. The company reports that it plans to increase production to three gigawatt-hours per year over the next five years.

"Houston has the people who know how to build and operate big hardware–ships, rigs, refineries and power systems," Mike Carter, co-founder and COO of Fleetzero, added in the release. "We're pairing that industrial DNA with modern batteries, autonomy, and software to bring back shipbuilding to the U.S."

Shell partners with UK-based co. for hydrogen electrolyzer pilot

ultra-efficient electrolyzer

Shell Global Solutions International, a subsidiary of Shell, which maintains its U.S. headquarters in Houston, has signed a collaboration agreement with London-based Supercritical Solutions to advance Supercritical’s ultra-efficient hydrogen electrolyzer technology toward a field pilot demonstration.

In the deal, the companies will collaborate on a paid technology feasibility study that will support the evaluation and planning of the pilot demonstration, according to a news release. Supercritical Solutions’ technology aims to deliver high-efficiency renewable hydrogen at a lower cost for the industrial hydrogen market.

"Signing this collaboration agreement with Shell is a major milestone for Supercritical Solutions and an important step on our commercialisation journey,” Luke Tan, co-founder of Supercritical, said in the news release. “We are directly addressing the cost and complexity barriers facing the renewable hydrogen market. We are excited to move forward with a company like Shell, whose global leadership has been proven to accelerate innovative technologies to market.”

Supercritical’s hydrogen electrolyser technology can operate at high temperatures and pressures of up to 220 bar without the need for an external hydrogen compressor, rare-earth materials or easily degradable membranes. The technology removes the typical compression step in the process while delivering hydrogen at industry standards. It requires significantly less energy than many traditional electrolyzers and is more cost-efficient.

This recent investment builds on an ongoing relationship between Shell and Supercritical. Supercritical was founded in 2020 and was runner-up in Shell’s New Energy Challenge, which helps startups and scaleups develop sustainable technologies, in 2021. Shell Ventures then invested in Supercritical’s Series A funding round in 2024 with Toyota Ventures.
