Built on Science.
Driven by Mission.
We are an American energy storage company combining deep battery science, AI-driven software, and a domestic supply chain to make sodium-ion the default choice for commercial, defense, and industrial energy storage.
Energy Storage You Can Bank On.
The energy transition demands storage that is safer, smarter, and cheaper to own over its lifetime. Coulomb Technology was founded to solve exactly that — building sodium-ion battery systems that eliminate the safety, supply chain, and total cost problems that have held back commercial energy storage adoption.
We believe the best energy storage system is one that works autonomously, generates revenue while it protects your operations, and never requires a service call. That belief drives every design decision we make — from cell chemistry to software to interconnection workflow.
Where We're Headed
A phased roadmap from beachhead products (DC cabinet + starter battery) to a U.S. cell factory, turnkey integration services, and ultimately a full Energy-as-a-Service platform — making Coulomb the easiest sodium-ion platform to specify, integrate, commission, and support.
How We Win
We win by becoming the easiest sodium-ion platform to specify, integrate, commission, and support — delivering bankable ROI data, pre-certified interconnection workflows, and autonomous AI dispatch that eliminates the operational burden for every stakeholder in the value chain.
61 Years of Battery, Energy & Scale-Up Experience
Our team brings together PhD battery scientists, systems engineers from Apple and Flex, energy industry veterans from Tesla and Natron Energy, and research institution collaborators from Oak Ridge National Laboratory and UT Austin — united by a single goal: making sodium-ion the default energy storage platform.
Deep Battery Science
Multiple PhD-level scientists specializing in battery chemistry, DFT modeling, cell development, and materials science — with research partnerships at Oak Ridge National Laboratory, Stony Brook University, and UT Austin.
Systems Engineering
Hardware and software systems engineers with backgrounds at Apple, Flex, AMETEK, and Lyten — bringing manufacturing scale-up, embedded systems, and power electronics expertise to every product we ship.
Energy Industry Veterans
Sales and operations leaders with 25+ years in EVs, chargers, and battery systems — drawing on experience from Tesla, Natron Energy, First Solar, and Eguana to build commercial channels and customer relationships.
Research & Government
Principal investigators at Oak Ridge National Laboratory and UT Austin, plus government affairs leadership with deep DOD and federal procurement expertise — enabling our Buy American Act and ITAR compliance pathway.
Why Sodium-Ion. Why Now.
Three fundamental problems have held back commercial energy storage adoption. Our sodium-ion chemistry and AI-driven software platform eliminates all three simultaneously.
Safety Without Compromise
Sodium-ion chemistry is fundamentally non-flammable — no thermal runaway, no cobalt, no lithium. This eliminates the mounting insurance scrutiny, AHJ approval friction, and liability exposure that liquid-cooled lithium-ion creates in enclosed industrial and defense environments.
Lower Total Cost of Ownership
Air-cooled design eliminates the HVAC system required by liquid-cooled LFP — removing capital cost, energy overhead, and maintenance complexity. Combined with a 20-year projected battery life and 14% lower 15-year TCO, Coulomb systems deliver the best lifetime economics in the market.
Domestic Supply Chain
The United States holds the largest sodium reserves in the world. Our domestic manufacturing pathway supports Buy American Act and ITAR compliance requirements for defense procurement — eliminating the geopolitical supply chain risk that defines every lithium-ion deployment today.
Trusted by the U.S. Military.
Our technology has been selected and funded by the U.S. Air Force and U.S. Navy — validating our sodium-ion platform in the most demanding operational environments in the world.
SBIR — Kirtland AFB Micro-Grid
837 kWh DC block deployment at Kirtland Air Force Base. Proves cabinet integration and performance in mission-critical environments. Validates our air-cooled, sodium-ion BESS for defense infrastructure.
SBIR P1 — Naval Starter Battery
24V / 30Ah sodium-ion starter battery for military applications. Proves high-power discharge and starter duty-cycle validation. Pathway to Phase 2 manufacturing and field evaluation with major OEMs.
Grants & Founder Funding
$2.2M in non-dilutive funding from government grants and founders — including California Energy Commission, NJ EDA Main Street Acquisition Support Grant, and New Energy New York CHARGE UP program.
