BioLargo Acquires Rights to Sodium-Sulfur Battery Energy Storage Technology

WESTMINSTER, CA / ACCESSWIRE / March 22, 2023 / BioLargo, Inc. (OTCQB:BLGO), a cleantech innovator and full-service environmental engineering company whose products address challenges to environmental and human health, has announced its acquisition of a proprietary sodium-sulfur battery technology. With a strategic focus on advancing technologies that address challenges in the water-energy nexus, the Company has identified this sodium-sulfur battery technology as a high-value solution that has a series of features that set it apart from currently available battery technologies in the market.

BioLargo has formed and secured initial seed capital for BioLargo Energy Technologies, Inc. ("BETI"), a subsidiary designed to address the ongoing shift toward renewable energy production and the growth in global electricity demand, and the consequent drastic expansion in energy storage capacity in the US and world-wide that will be needed to accommodate increased demand and the intermittent nature of renewable energy sources like wind and solar.

BETI will lead the manufacturing, scale-up, and operations for the sodium-sulfur battery technology with the help of one of the technology's original developers, who has joined BETI. Batteries built based on the underlying technology a decade ago demonstrated features that far surpass comparable lithium-ion batteries, the dominant incumbent technology in the market:

• This sodium-sulfur battery technology demonstrates increased safety, no runaway fire risks, and a more sustainable design - with no rare-earth elements - that is capable of being manufactured completely from the domestic supply chain.
• Unlike lithium-ion batteries, BioLargo's battery can charge and discharge completely, with no degradation of performance, ensuring virtually unlimited charge/discharge cycles.
• BioLargo's battery technology also demonstrates increased energy efficiency and energy density in comparison to lithium-ion batteries, and a longer useful life expectancy of at least ten years.

BioLargo's battery operates at a higher temperature and has relatively heavier casing as compared to lithium-ion batteries, making it well suited for bringing superior performance to stationary applications like electric vehicle charging stations, grid-scale energy storage, and commercial and residential storage.
