WEST - Optimized Electrostatic Energy Storage Modules

Supercapacitor technology offers significant advantages over chemical storage alternatives. WEST’s scalable electrostatic storage solutions empower clients to upgrade their systems as energy needs grow, with building blocks designed to last for decades.

Our autonomous modules require no periodic maintenance throughout their lifetime. Field servicing, if ever needed, is simple, with easily replaceable components and minimal tools.

Designed for extreme temperatures, our modules operate reliably in both hot and cold environments without the need for parasitic heating or cooling loads.  Electrostatic storage eliminates concerns like degradation, BMS limitations, and efficiency loss – letting you design with confidence!

NO HEAT GENERATION OR THERMAL RUNAWAY
Chemical batteries produce heat during operation which, at a certain point, can become exothermic, meaning it burns at a temperature that is self-sustaining and extremely difficult to extinguish. Because WEST modules operate without creating heat, this risk of fire does not exist.

20 YEAR WARRANTY
Modules are scalable energy storage building blocks with an expected lifespan of 45 years. WEST storage systems far surpass the average lifespan of Li-ion solutions.

MULTIPLE CYCLES PER DAY
WEST modules are capable of more than two charging and discharging cycles per day. Many chemical battery warranties are voided by over-cycling or simply limited to one cycle/day or less.

ULTRA-HIGH EFFICIENCY
WEST modules are 97% efficient at the module level. Compare this to many Li-ion batteries that lose as much as  10% (in heat) in every cycle. Over time these Li-ion losses increase and become even more prohibitively expensive.

FAST CHARGING
WEST modules are capable of 30-40 minute charging, allowing them to address any energy storage need in the market. No chemical battery can compete with this performance (lead acid = 10-12 hours, Li-ion = ~4 hours

DISCHARGE IN MINUTES OR MONTHS
WEST modules can discharge super-fast OR super-slow OR hold a full charge for years without leakage. Our long duration energy storage suits the needs of all end-users.

100% USABLE CAPACITY
Many Li-Ion battery manufacturers tell customers they can use 100% of the storage. With chemical batteries this can only be achieved by either:
1) Placing more than nameplate capacity into the system or
2) Building significant degradation allowance into the warranty.

MINISCULE CAPACITY DEGRADATION
Proven in the field in extreme temperatures for 10 years without measurable degradation. Since the technology provides for electrostatic storage (energy stored as energy), instead of a heat-producing electrochemical reaction (energy stored in a chemical), there is no stress on the materials over time.

OPERATE IN EXTREME HEAT & COLD
WEST modules can operate in a wide range of temperatures, from -40ºF to +150ºF / -40ºC to +65ºC without experiencing damage. Li-Ion batteries will  experience permanent damage at temperatures below  -5ºC / 23ºF and above +45ºC / 113ºF.

VIRTUALLY NO MAINTENANCE
WEST modules need virtually no periodic maintenance. They monitor and protect themselves throughout their lifetimes. Every part or component can be repaired and replaced in the field.

COST EFFECTIVE
Due to its long life, ability to cycle multiple times per day, and high round-trip efficiency, WEST storage delivers the lowest long-term cost of energy in the industry. Importantly, WEST storage systems last as long or longer than alternative off-grid or grid-tied system.  

FLEXIBLE MODULAR DESIGN
WEST storage systems are designed to be expanded over time as your energy needs grow. Plus, our use of standard components makes maintenance a breeze.

WEST is redefining energy storage with our optimized supercapacitor technology. Discover why clients across the globe are making the shift to WEST.

Safety

Most batteries are “electrochemical” devices. WEST’s energy storage modules are “electrostatic” devices, wherein electricity is stored as electricity. Since this process does not involve a chemical conversion, our systems do not generate heat. Without heat and chemicals, fire risk is virtually erased, and by eliminating the need for system heating and cooling, WEST offers better and safer performance, a 45 year design life and lower cost. 

A 45 Year Build Life

WEST’s co-founders have built a product that is changing the industry. Our optimized supercapacitor-based systems were designed and developed after identifying the biggest challenges in the field, and then developing a product that could address them effectively. 

20 Year Warranty

Our out of the box thinking resulted in remarkable performance and results that we can back with a rock solid 20 year warranty.
