Coulomb technology: advanced hvac-free sodium-ion energy storage
Coulomb Technology develops advanced, air-cooled sodium-ion battery energy storage systems, such as the GridReady™ platform, to provide safer and more reliable energy storage for commercial, industrial, and defense applications. These systems matter because they eliminate the fire hazards and complex HVAC cooling requirements of traditional lithium-ion batteries, operating safely in extreme temperatures (-40°C to +60°C) while reducing the 15-year total cost of ownership by roughly 14% and avoiding volatile, foreign-dominated lithium supply chains. The solution works by pairing highly durable sodium-ion cells—capable of 8,000+ cycles and safe zero-volt discharges—with the proprietary EnergiOS™ software platform, which uses AI to automatically optimize energy dispatch for bill savings, backup power, and utility compliance. Having proven their technology at Technology Readiness Level 6 through active, funded pilots with the U.S. Air Force (600,000foran837kWhmicrogrid) and the U.S. Navy(240,000 for starter batteries), Coulomb's next steps involve raising an $8 million Seed round, securing commercial integration partners, and establishing a fully domestic U.S. supply chain, which includes a planned 10 GWh cell manufacturing plant in Upstate New York.
About Chasm Opportunities
Chasm Opportunities is a consulting firm established in 2024 that specializes in helping dual-use technology companies navigate the process of transitioning their innovations into defense and government markets. The firm offers strategic consulting, program management, and relationship management services, aiming to bridge the gap between early-stage development and government programs of record. Founded by David Madden, who draws on over three decades of experience in defense acquisition, research, and innovation, the company utilizes a proprietary methodology to map project requirements, identify sponsors, and secure transition paths for small business clients.
By focusing on process and execution, Chasm Opportunities helps founders and small business leaders move past common failure points in defense contracting, such as navigating SBIR/STTR programs and understanding sponsor logic. The firm works across various industries, including energy systems, material development, and manufacturing, providing personalized guidance to move credible prototypes toward successful integration into military and commercial applications. Through its private community, Chasm Crossers, the firm also supports a network of founders engaged in the complexities of government market entry.
