Warren Buffett Backs Domestic Lithium Extraction from Geothermal Brine: A Sustainable Solution for the Electric Vehicle Boom?

The electric vehicle (EV) revolution is driving a surge in demand for lithium, a key component of lithium-ion batteries. This has sparked a global race to secure reliable and sustainable sources of the metal. Enter Warren Buffett, the legendary investor, who is making a strategic move into lithium extraction through a joint venture between Berkshire Hathaway Energy Renewables (BHE Renewables) and Occidental Petroleum. This innovative project aims to extract lithium from geothermal brine, a potential game-changer for the domestic lithium supply chain in the United States.

Why Geothermal Brine for Lithium Extraction?

Traditionally, lithium is extracted from brines or hard rock deposits. However, these methods can be environmentally destructive and energy-intensive. Geothermal brine, on the other hand, offers a more sustainable approach.

Why Warren Buffett Domestic Lithium Extraction?

• Readily Available Resource: Geothermal power plants already pump vast quantities of hot, salty brine to the surface of the earth to generate electricity. This brine naturally contains lithium, making it a readily available source for extraction.
• Reduced Environmental Impact: Extracting lithium from geothermal brine can piggyback on existing infrastructure, minimizing additional land disturbance and energy consumption. Additionally, geothermal energy is a clean and renewable source of power, further reducing the environmental footprint.
• Potential for Co-Production: The joint venture between BHE Renewables and Occidental Petroleum leverages existing geothermal facilities for lithium extraction alongside electricity generation. This co-production approach can potentially reduce overall costs and improve economic viability.

The Imperial Valley: A Lithium Hotspot

The focus of this new venture is California’s Imperial Valley, a region known for its geothermal resources. The Salton Sea, located within the Imperial Valley, is estimated to hold vast lithium reserves. BHE Renewables operates ten geothermal power plants in the area, processing millions of gallons of lithium-rich brine per minute.

Pilot Testing and Building a Domestic Supply Chain

The collaboration between BHE Renewables and Occidental Petroleum will utilize technology developed by TerraLithium, a subsidiary of Occidental Petroleum. This technology will be piloted at BHE Renewables’ Imperial Valley facilities to determine the feasibility of extracting lithium in an environmentally sound manner.

If successful, the project could pave the way for the construction of commercial-scale lithium production facilities in the Imperial Valley. This would significantly contribute to establishing a robust domestic lithium supply chain in the US, reducing reliance on foreign sources and potentially lowering costs for EV manufacturers.

The Competition: ExxonMobil Enters the Fray

Warren Buffett is not alone in recognizing the strategic importance of lithium. In late 2023, ExxonMobil announced its own plans to enter the lithium production game, aiming to be a leading supplier for EVs by 2030. This increased competition highlights the growing importance of lithium in the clean energy transition.

Warren Buffett: Challenges and Considerations

Despite the potential benefits, extracting lithium from geothermal brine is not without challenges. Here are some key considerations:

• Environmental Impact: While generally considered more sustainable than traditional methods, the environmental impact of geothermal brine extraction needs careful evaluation. Potential concerns include water usage, brine disposal, and potential seismic activity.
• Technical Challenges: Developing efficient and cost-effective technologies for lithium extraction from geothermal brine requires ongoing research and development.
• Regulatory Hurdles: Obtaining permits and navigating environmental regulations can be a significant hurdle for new extraction projects.

Warren Buffett: OXY Stock

In a downturn for oil stocks, Occidental Petroleum (OXY) fell 1.4% to $59.78 on Tuesday. This follows a 3% drop on Monday, bringing the stock price down 15% since its April 12th peak of $71.19. According to MarketSurge charts, OXY is currently trading below its key 200-day moving average. The decline coincides with a broader slump in the oil market, with West Texas Intermediate crude oil prices dipping to a four-month low below $73 a barrel

In a move highlighting the shift in energy demands, Warren Buffett’s Berkshire Hathaway subsidiary, Berkshire Hathaway Energy, has partnered with Occidental Petroleum (OXY) to enter the lithium production game. This comes on the heels of Exxon Mobil (XOM) announcing similar plans in late 2023, aiming to be a major lithium supplier for electric vehicles by 2030. Exxon’s ambitious goal targets enough lithium production to support over 1 million EVs annually, with their first production set for 2027. Discussions between Exxon and potential customers in the EV and battery manufacturing space are ongoing.

The Road Ahead: A Sustainable Future for Lithium?

The joint venture between Berkshire Hathaway and Occidental Petroleum represents a significant step towards a more sustainable domestic lithium supply chain in the US. The success of the pilot project and the ability to address potential environmental concerns will be crucial in determining the long-term viability of this approach.
