Safety is a top priority for defense applications, where personnel and equipment are often deployed in high-risk environments. Traditional lithium-ion batteries present significant fire hazards, particularly in confined or extreme conditions where overheating can lead to thermal runaway—a chain reaction that causes fires or explosions. This is a serious risk in military applications where evacuation or fire suppression can be challenging.

Many military operations, especially those in remote or contested areas, rely heavily on diesel generators, which are expensive and logistically complex to maintain due to fossil fuel supply chains. In combat zones, fuel convoys are often targeted by enemy forces. By using non-flammable Alsym Green battery systems alongside renewable energy systems, military units can reduce their dependency on fuel convoys, lowering the risks associated with transporting fuel and decreasing logistical burdens. Alsym Green’s low LCOS can also reduce the dependency on fossil fuels by providing a cost-effective alternative.

Alsym Green’s non-flammable chemistry virtually eliminates the risk of fire, even in the event of physical damage or exposure to extreme temperatures. With a wide operational temperature range, Alsym Green batteries can withstand a wide variety of environmental conditions without compromising performance or safety. This makes them ideal for use in both hot and cold climates, ensuring continuous and safe operation without the need for complex cooling or heating systems. Furthermore, their ability to withstand damage and abuse enhances their durability in demanding military scenarios, reducing the risk of catastrophic failures during critical missions.

Alsym Green battery systems not only enhance safety by eliminating fire risks but also improve health conditions for military personnel by reducing the reliance on noisy, emission-heavy diesel generators. By providing clean, silent power, Alsym Green helps lower exposure to harmful diesel exhaust and reduces noise pollution in confined spaces such as forward operating bases, vehicles, and naval vessels, creating a safer and healthier working environment for defense operations.

Military operations require energy storage systems that are capable of delivering reliable, long-duration power across a wide range of applications. Whether powering bases, command centers, or remote operations, energy storage systems must offer both flexibility and high performance. Alsym Green batteries provide 2x to 10x the energy density of other non-lithium alternatives, such as zinc-bromine or vanadium flow technologies. This allows a 20’ BESS container incorporating Alsym Green to store up to 1.7 MWh of energy, providing military installations with a robust and efficient energy solution.

The batteries’ wide discharge range (2 to 110 hours) and fast recharge time (as little as 4 hours) make them ideal for both short-term and long-duration applications, ensuring that defense units have consistent, reliable power when needed. Alsym Green also delivers round-trip efficiency comparable to lithium-ion batteries, without the associated risks. Additionally, its industry-leading levelized cost of storage (LCOS) makes it a cost-effective solution for defense applications, helping the military manage energy costs while maintaining operational readiness.

Alsym Green’s wide operating tolerances and temperature range provide critical flexibility for the DoD by ensuring reliable performance in diverse and extreme environments, from desert bases to arctic outposts. Alsym Green can operate effectively in military installations around the world, reducing the need for complex cooling or heating systems, which are crucial for forward-deployed units and harsh climate scenarios.

With a high round-trip efficiency (RTE) of 92%, Alsym Green maximizes energy use, making it ideal for applications such as microgrids, where efficient energy storage and discharge are essential to maintaining operational readiness. Its low self-discharge rate ensures that stored energy remains available for extended periods, critical for operations in remote or off-grid locations where energy replenishment may be intermittent or delayed.

Additionally, Alsym Green’s ability to be stored at zero state of charge allows military units to stockpile batteries for long-term missions or disaster recovery scenarios. For example, in forward operating bases or disaster relief missions, these batteries can be activated on demand without requiring constant recharging, providing the DoD with strategic energy reserves for unpredictable situations or extended deployments.

Alsym Green’s unique combination of safety, supply chain resilience, and high performance makes it suitable for a wide range of military applications:
