Energy Storage Battery Selection
energy storage sub-chemistry analysis
Fractal is an expert at battery selection for energy storage systems. Through hands-on experience and cutting-edge sub-chemistry optimization modeling, Fractal can drastically increase the economics of your energy storage project.
There are many sub-chemistries of batteries available in the marketplace. Each variation has its own set of parameters that Fractal will rigorously evaluate to determine the best fit for each Business Model.
Build dispatch model based on maximum revenue and/or cost avoidance potential
Identify power and energy requirements for each Business Model
Identify roundtrip efficiency due to C Rate, SOC and losses
System sizing and capacity augmentation schedule
Quantify and assess costs (Capital & O&M)
Determine the most reliable and cost-effective solution
fractal selects the best technology and chemistry for your project
Fractal is vendor and technology agnostic. We design systems with the highest reliability, lowest total cost of ownership, and maximum revenue for the life of your project. There are several battery storage technologies that are available in the utility marketplace. Lithium-ion is currently the leading technology, but niche applications may require other technologies e.g. high temperature, off-grid applications.We have worked extensively with all of the following electrical energy storage technologies:
|Nickel-metal Hydride Batteries|
|Sodium-nickel Chloride Batteries|
|All-vanadium Redox Flow|
|Zinc-bromine Redox Flow|
|Zinc-iron Redox Flow|
|Natural Gas Fuel Cells|
|Compressed Air (CAES)|
During the battery selection process, Fractal considers and evaluates many critical factors to determine the best-fit technology. For a given duty cycle, the difference between Lithium Nickel Manganese Cobalt Oxide, Lithium Titanate or Lithium Iron Phosphate can be upwards of 80% profitability.
capacity degradation modeling
Fractal models degradation to determine annual battery capacity (MWh) and energy capacity (MWh). Fractal can also calculate and optimize a PPA rate ($/MWh) for energy storage as a service models.
