Advanced Energy Storage: Linchpin for a Renewable Energy Future
The performance of lithium ion at a fraction of the cost and risk
Alsym™ Energy has developed an innovative low-cost, high-performance rechargeable energy storage technology that’s free of lithium and cobalt, and ideal for applications such as stationary storage, maritime shipping, and electric vehicles.
By using readily available, inherently non-toxic and non-flammable energy storage materials, Alsym is working to deliver wide-duration storage with performance comparable to lithium ion at a much lower cost, speeding the pace of decarbonization for people around the world.
Markets We Serve
- Short & Long-Duration Storage
Short & Long-Duration Energy Storage
Short & Long-Duration Energy Storage
Electricity generation is shifting to renewables, but solar and wind power must be backed up at scale to ensure 24/7 availability. High battery prices are slowing the pace of storage deployment, and storage integrators are competing with automakers for supply. Lithium-ion systems are mostly unsuitable for urbanized areas due to fire risks and production of highly toxic gases. As high-profile storage fires become more common, communities are working to delay or even block new storage installations.
Safer options exist, but most have low energy densities and low power with large footprints. With system-level capacities similar to lithium-ion and the ability to operate at temperatures up to 45 C, Alsym is the only high-performance, non-flammable battery storage option capable of replacing lithium-ion in urban areas and hot climates. By eliminating the risk of fires and explosions, Alsym batteries are also less expensive to operate as they don’t require expensive climate control or liquid cooling systems.
Alsym technology combines fast charge rates and user-configurable discharge durations with high round-trip efficiency in a minimal footprint for maximum energy and power with low LCOS. With high power density and on-demand user-configurable discharge rates, wide-duration Alsym batteries are an ideal solution for both short-duration and long-duration energy storage (LDES) needs.
Marine, Maritime & Off-Shore
Marine, Maritime & Off-Shore
There’s little tolerance for hazardous battery chemistries in maritime applications. Unlike lithium-ion batteries, Alsym batteries are made from materials that are inherently non-flammable, reducing the risks to human life and cargo and helping to lower insurance costs and cumulative liabilities.
Motorcyles, Scooters, & Two-Wheelers
Motorcyles, Scooters, & Two-Wheelers
The global electric motorcycle and scooter market is set to triple by 2030. Today, over sixty million are sold every year, and most run on fossil fuels. Battery electric models are in demand, but buyers are extremely cost-sensitive and concerned about battery fires. Lithium-ion batteries in two wheelers can spontaneously combust due to poor heat dissipation—a problem that will only get worse as the world warms.
Our low-cost, non-flammable batteries are poised to be an ideal solution for the two-wheeler market, maximizing performance and profit margins while greatly improving rider safety.
Electric Vehicles
Electric Vehicles
Even with recent advancements, the cost of lithium-ion batteries is roughly double what’s needed for EVs to reach cost parity with comparable internal combustion engine (ICE) vehicles. This means that EVs are largely confined to the premium and luxury end of the market. Low-cost, high-performance Alsym batteries will enable global adoption of battery-electric vehicles across consumer and commercial segments.
Energy storage technology without lithium and cobalt
Our energy storage technology avoids many of the issues that surround lithium-ion batteries and uses no lithium or cobalt. Alsym energy storage batteries are non-flammable and non-toxic by design, using readily available materials.
